Since the 1980s, the economic development of our country has been advancing by leaps and bounds, and all walks of life have achieved great results that attract worldwide attention. The living standards of the people have been greatly improved, and the dietary conditions and lifestyle have also been greatly changed. In particular, changes in rural dietary conditions and dietary patterns. People are pursuing a fast, simple, and comfortable lifestyle. Some people have changed their lifestyle from making breakfast to instant noodles, bread, ham, bag milk, etc. Various foods, gifts, and fruits and vegetables have also been changed from paper, bamboo, and wood packaging. For exquisite plastic packaging materials. Every household produces plastic garbage every day, so plastic waste generated from life is an important factor causing [white pollution". At present, the city's "white pollution" has received the attention of the government and relevant departments and has been initially resolved. However, 80% of China`s population is in rural areas, and the environmental pollution caused by plastic living garbage is increasing day by day. The pollution consequences have not aroused the general public`s understanding. China`s large population accounts for one-sixth of the global population. It is the common responsibility of the entire people and even humanity to manage plastic pollution, to protect the earth, and to create a beautiful living environment for our own survival and future generations. At present, the government has not yet had the ability to handle rural plastic waste. This requires governments at all levels to increase their management and publicity efforts. If we want to fundamentally solve this pollution problem, we must research and produce and use those biodegradable plastic packaging materials. This is a major issue that needs urgent solution. At present, domestic and foreign countries have developed and produced a variety of biodegradable plastic packaging materials instead of plastic packaging materials, and have been actively promoted and applied. 1 Degradable plastic film material 1.1 Water-soluble plastic packaging film The main raw materials of this product are polyvinyl alcohol (PVA) and starch, all components (including additives) are all C"H"O compounds and are non-toxic, and only physical dissolution occurs between the components during the filming process. , to improve its physical properties, mechanical properties, process performance and water solubility. Water-soluble film products belong to green packaging materials [1]. As for the degradation mechanism, PVA has the degradability characteristics of water and bio-industry. It dissolves first in water to form a glue solution and penetrates into the soil to increase soil stickiness, air permeability and water retention. Sex, especially suitable for sand soil transformation, the PVA in the soil can be decomposed by bacterial strains isolated from the soil, and ultimately can be degraded into CO2 and H2O. 1.2 Plastic film made of potato and whey This product is a kind of biodegradable plastic film made of potato and whey, which is produced by using enzymes to convert whey formed during cheese making and disused potatoes into The glucose syrup is then fermented with bacteria into a liquid containing lactic acid. The cheese in the liquid is separated by electrodialysis and heated to evaporate the water, leaving behind the polylactic acid molecules that can be made into films and coatings. The plastic film thus produced can be made into a fresh-keeping bag and replaces the packaging material coated with polyethylene and waterproof wax. The greatest advantage of this product is that it can be decomposed into lactic acid which is harmless to the environment. 2 Degradable foam material 2.1 Degradable foam plastics Degradable plastics can be divided into synthetic photodegradation according to the degradation mechanism, photodegradation with photosensitizers, and multifunctional plastics with various plastics. For synthetic photodegradable plastics, polyhydroxybutyrate (PHB) and polyhydroxylase lipid (PHV) are mainly studied at present. The degradation principle is that the polymer absorbs ultraviolet light and initiates photoinitiation, so that the chain energy is weakened and long chain is split. Lower molecular weight fragments. The physical properties are degraded, and the lower molecular weight fragments are further oxidized in the air, resulting in radical chain scission and further degradation into CO2 and water. 2.2 Add photosensitizers Photodegradable plastics Add a small amount of photosensitizer in the plastic processing process, due to the photo-initiating effect of photosensitizer and photochemical reaction to generate free radical initiators, it can accelerate the process of polymer photodegradation, photodegradable plastic only Can be degraded under solar irradiation conditions. 2.3 Biodegradable plastics are mostly incompletely biodegradable with starch and polyolefin plastics. The degradation mechanism of such plastics is that starch granules are first attacked and consumed by fungi and bacteria, thereby weakening the strength of the plastics. At the same time, after the plastics are in contact with certain salts existing in the soil, peroxides are formed by self-oxidation and promote plastics. The polymer chains in the polymer break, they promote each other and complement each other. The bacteria consumes starch, which increases the plastic surface and facilitates auto-oxidative degradation. As time passes, the polymer chain gradually breaks and shortens, causing the plastic strength to decrease until the molecular weight of the polymer is finally reduced to the extent that it can be metabolized by microorganisms. 2.4 Fully biodegradable plastics The raw materials are mainly natural polymer materials such as starch, honey and biodegradable synthetic polymers or water-soluble polymer materials as the main raw material, and the degradation mechanism is in the normal outdoor natural conditions, natural UV rays, oxygen, and microorganisms act on the product, breaking the main chain of the polymer, causing a drastic decrease in molecular weight. The starch entangled in the polyolefin molecules is decomposed at the same time. The product is broken at the touch, and the remaining substances can be accepted by the environment in insects and microorganisms. Continuing to return to nature. 3 Foaming Plant Fiber Buffer Packaging Materials Foaming plant fibers are made from plant fibers (waste newspapers, cardboard boxes and other plant fiber materials, etc.) and starch addition aids. At present, research on the production and mechanism of foamed plant fiber cushioning packaging materials are being conducted at home and abroad. Samples made in the laboratory have shown that the development of this product has great market potential [3]. The process methods adopted for the plant fiber foamed products are mainly concentrated on the non-added chemical foaming agent, that is, the foaming agent is not required to generate foaming, and the raw material is foamed by water vapor to form a granular foaming pulping. The product is more environmentally friendly than chemical foaming with additives. 4 Traditional Ecological Packaging Materials 4.1 Paper packaging materials Paper used as food packaging materials is the most economical, suitable printing, suitable for promotion, popular, environmental protection and pollution-free traditional packaging materials. In history, the majority of people used grass paper and paper ropes as various food packaging materials. China's papermaking resources are very rich, and the production process is simple. Most foods, fruits and vegetables can use paper products as packaging materials. According to experts` prediction, China`s current consumption of paper and paperboard packaging is about 50 million tons, of which the largest amount is corrugated cardboard and honeycomb paperboard. China can consume 15 million tons of corrugated paper annually. Corrugated paper is a kind of buffer packaging material that people used earlier. It has good processing performance, low cost, wide application temperature range, and it is not only conducive to environmental protection, but also can be recycled. China's accession to the World Trade Organization has a greater demand for paper product packaging, and some developed countries have stricter environmental food packaging requirements. Researching the use of paper products as food packaging will give companies a golden opportunity for development. 4.2 Wood and Bamboo Packaging Materials Bamboo and bamboo packaging materials are used in food packaging. Our country has a history of thousands of years. Foods such as noodles and pickled foods are woven into sticks using sticks and bamboo sticks, and then they are leak proof inside and outside the tins. Made of materials, especially all kinds of fear of squeezing foods need more bamboo and bamboo packaging, all kinds of fruits and vegetables still use bamboo or twigs woven into boxes. Bamboo and wood are rich in packaging materials, low in price, easy to recycle or reuse, and non-pollution. For example, the Great Wall dry red wine is packaged in wooden boxes. The wooden packaging box is noble and beautiful, and improves the grade and popularity of the wine, especially As a gift, a wooden box is a gift for relatives and friends, which is very popular among consumers. Research and development of bamboo and wood materials for food packaging, how to make more food use its bamboo and wood packaging, how to make traditional bamboo and wood packaging mechanized production, which is the responsibility and obligation of packaging design researchers. At present, the degree of mechanization is relatively high, and the development of bamboo and wood packaging flow operations, especially the use of synthetic or compressed wood, is more highly mechanized and is more conducive to mechanized production.

It specializes in the design, manufacture and sales of consumer packaging products. It has factories in 36 countries around the world. It has a population of 15,000 people and an annual turnover of 2.2 billion euros. The company recently produced a plastic cup named Compacto. This polystyrene plastic cup uses a special embossing process, which is easy to classify and distinguish. It is a plastic cup for hot drinks that is specially used for beverage vending machines. . The new Compacto retail beverage plastic cup is only 3 grams in weight. It is available in white cups and two-color cups embossed with coffee beans. It can be used in the hot beverage retail market. The biggest highlight is that when the cups are stacked on top of one another, the space is small. Compared to other common plastic cups, the 120 Compacto plastic cup stacks occupies a space equivalent to that of stacking 100 normal plastic cups. In this way, the Compacto plastic cup becomes more compact when it is placed in the box, which increases the number of cups to be packed, thus reducing the packaging cost. The Poole Group also received inspiration from the world-renowned Coca-Cola 1916 Contour bottle design to develop the latest Contour plastic cup for Coca-Cola. Coca-Cola's exclusive Contour plastic cups are designed to be processed with polystyrene and processed using the company's thermoforming process technology.

For convenience retailers, these single-use Coca Cola plastic cups have a high-quality texture that is cleaner, safer, and easier to handle than general-purpose glass bottles. And it has a small footprint and is the ideal beverage cup. Reprinted from: Foreign Plastics

Plastic cups are popular with many people, especially children, adolescents, and activists. Because plastic cups have a variety of materials, the use of plastic products with poor safety levels can cause safety problems for long-term use. Because plastic cups have the advantages of various shapes, bright colors, low prices, and non-breakable, they are deeply loved by the public. Most plastic cups (such as space cups) that are now available on the market are made of polycarbonate (PC), which is one of the main raw materials for producing polycarbonate plastics. When choosing a plastic cup, you should pay attention to two points: First, look at the production license, and second, look at the plastic recycling mark. Production licenses are proof that the state allows companies to produce related products and that their products meet relevant safety requirements. The plastic recycling mark marks the basic material of the plastic, generally located at the bottom of the plastic product. It is a triangle with several numbers ranging from 1 to 7 to indicate different materials. If there is a [7" or [58" in the middle of the triangle and a PC is written below, the product may contain [bisphenol A". If there is a cup of PC material in your hand, how can you reduce the risk? Before using for the first time, wash with baking soda powder and warm water, and dry naturally at room temperature, because the bisphenol A will be released when it is used for the first time. many. Avoid heating during subsequent use. Do not use a dishwasher or a dishwasher. Do not expose it to direct sunlight for long periods of time. Do not use hot water or tea. If the container has any broken or broken, it is recommended to stop using it, because if there are tiny pits on the surface of the plastic product, bacteria can be easily hidden. At the same time to avoid repeated use of aging plastic appliances. Drinking glasses is still the preferred glass, ceramic or stainless steel cup. If you really want to use plastic cups for tea or hot water, it is best to choose a colorless plastic triangle with a [5" mark in the middle. This material is PP. The name of the plastic component is polypropylene, which can withstand high temperatures above 100 degrees. It is also harmless to the human body.

[Chinese Packaging Network News] PC is not only polycarbonate, is one of the most common plastic, this material itself is non-toxic, especially for the manufacture of baby bottles, space cups, etc., because it contains bisphenol A and controversial. In theory, as long as bisphenol A is 100% converted into a plastic structure during the production of a PC, it means that the product is completely free from bisphenol A, and therefore it becomes no threat to health. However, if a small amount of bisphenol A is not converted into a plastic structure of PC, it may be released into food or drink and threaten the health and safety of users, especially young people. To choose the plastic cup first understand PC and PP PP is an abbreviation of polypropylene, it has good heat resistance, the product can be disinfected and sterilized at a temperature above 100°C, and it is not deformed under 150°C under the condition of no external force. It is one of the most common plastics for microwave ovens. . But a closer investigation will reveal that PC material products on the market tend to be more expensive than PP material products. Customers tend to choose the concept of [more expensive, better quality". In fact, the price difference is due to the fact that there is currently 1 tons of PCs on the market. The price is much higher than the price of 1 ton PP. The relative ratio between the two materials will be found, PP wear resistance worse than the PC, so in the production of transparent cups, PCs are generally used as a material, PC products are more beautiful than PP products. But from a safety point of view, the processing temperature of PP plastics is 180-240°C, so boiling water does not decompose it, so PP is safer than PC. Is it dangerous to have boiled water in a PC cup? The cup with a bottom number of 7 is made of polycarbonate, ie PC. The general PC material plastic cup can withstand -30-140 °C temperature, but this is the physical properties of the material, but said that this material will not crack, melt in use at this temperature. But when we look at food safety, the higher the temperature, the more BPA will be released from the PC and the faster it will be. So the reason why PC has a health threat is because it will release bisphenol A at high temperatures, then this makes people "smell the color change" where is bisphenol A sacred? Bisphenol A (BPA) is commonly used in the industry to synthesize materials such as PC and epoxy resins. In modern industry, bisphenol A can be said to be ubiquitous, and it has its presence in mineral water bottles, medical devices, and food packaging. Every year, the world produces nearly 27 million tons of plastic containing bisphenol A. Although its industrial use is very large, it is not harmful to humans. According to the study, bisphenol A can lead to endocrine disorders, and may even cause obesity caused by cancer and metabolic disorders. The European Union believes that bisphenol A-containing milk bottles will induce precocious puberty. From March 2, 2011, the production of baby bottles containing chemical substances such as bisphenol A was banned. Therefore, it is best not to use PC cups for hot water, and do not place them in a microwave oven.

From January to August 2012, China`s output of daily plastic products has shown a good momentum of growth. The following are the specific data: From January to August 2012, the output of daily-use plastic products reached 3.077 million tons, a year-on-year increase of 10.83%. In August, China produced 377,000 tons of daily-use plastic products, a year-on-year increase of 11.61%. Judging from the output of various provinces and cities, from January to August 2012, the output of daily-use plastic products in Guangdong Province reached 710,000 tons, an increase of 21.56% year-on-year, accounting for 23.09% of the country's total output. Followed by Zhejiang, Hunan and Jiangsu provinces, they accounted for 20.58%, 8.51%, and 6.93% of the total output respectively.

No mold line, good anti-fall ability 2. development path: The first stage: Until the late 1970s and early 1980s, a large number of glass containers were used, and PVC, PE plastic bottles were produced using the extrusion blow process. The second stage: From the late 1980s to the 1990s, more glass containers were still used, but the injection blow process replaced the extrusion blow process with its advanced properties. In order to improve the quality of pharmaceutical packaging containers, the state has focused on supporting a number of state-owned enterprises such as Shanghai Haichang, Wuxi Hongguang, Wuhan Xiamei, Shandong Xinhua, Qinhuangdao Plastics, etc. The introduction of a number of WEATON injection blowers has greatly increased the strength of PE drugs. Bottle market share and quality. The third segment: In the early 1990s, with the development of injection technology in the country, PET bottles began to enter the pharmaceutical packaging arena, represented by Guangdong Southern Packaging Co., Ltd., and introduced a Faraday blowing device from the Japan Greenwood Solid Research Institute. A large number of PET bottles were produced and successfully delivered PET bottles in southern China. At the same time, due to the environmental impact of the glass production process, the Bureau of Medicine issued a policy that plastic products will be used instead of glass containers. Until 01 years ago, a pattern was formed: Southern Packaging used plastic PET bottles produced by one-step AQM machines to win most of the southern markets, while Central China, East China, and North China markets still used PE bottles, but some of them used two-step injections. Pull PET (represented by Huang Yanji) PET bottles. 3. Equipment development process: The rapid development of China's pharmaceutical packaging products in recent years, the increasing demand for plastic packaging containers, plastic packaging container molding equipment is also growing. As the blow molding equipment first injects the bottle mouth during operation to ensure the accuracy of the bottle mouth, and then blows the bottle body, thereby preventing the gas inside from penetrating into the bottle, ensuring that the bottle mouth and the bottle cap have Close performance. China's plastic injection blow-molded hollow container equipment can be produced in small quantities during the "6th Five-Year" and "7th Five-Year" period, but the precision and performance of the equipment itself are not as good as foreign equipment. At present, the production of this type of equipment requires greater efforts to improve precision and become a truly accurate injection blower. The so-called "precision injection blower" not only refers to the high stability of the equipment in the high-speed and high-pressure molding process, but also requires a high stability in the production of container size fluctuations and quality fluctuations, that is, the size of the production of the various parts of the container. And the geometric shape accuracy is higher, and other indicators such as the appearance of the container and the intrinsic quality of production efficiency can reach a higher level. This paper forecasts the development of injection blowers in China for the current and future period of time as follows: (1) Hydraulic control system with high sensitivity, high reproducibility and stability. In the hydraulic system, in order to achieve energy conversion, transmission and control functions, the plunger screw of the precision injection blower is driven by a hydraulic motor and is controlled by a hydraulic system. Injection molding pressure injection speed, plasticizing pressure, etc. Both are controlled and evenly regulated by the mounting system on the control valve of the hydraulic system. The adjustment of the speed of the blower screw depends on the electronic instrument. The electronic indicator consists of a sensor and a display. According to the difference in the unidirectional pulse, the computer determines the value of the screw speed and displays the value on the display accurately. (2) It has fine-tuned control performance, excellent and reliable operation, and easy-to-use electronic control system. Note that the adjustment of the speed of the blower screw depends on the electronic instrument. The electronic indicator consists of a sensor and a display. According to the difference in the unidirectional pulse, the computer determines the value of the screw rotation speed and accurately displays the value on the display. (3) High-speed and high-pressure injection of parisons can be performed, and the shrinkage of the container can be minimized during blow molding. Another feature of the precision injection blower is the development of injection pressure high pressure, the purpose of which is to reduce the shrinkage rate after blow molding and increase the density of the container. Due to the high injection pressure and fast injection speed, compared with ordinary injection blower, the mold clamping system has good rigidity, good durability, sufficient injection mold clamping force, and can resist the pressure of high-pressure, high-speed injection of molten plastic. The mold deformation is minimal. (4) It has an excellent plasticizing device, which can fully plasticize the plastic under uniform temperature, and can measure correctly. When the melt is injected into the parison mold and begins to be formed into the blow mold, the plunger screw of the inner barrel of the injection blower rotates, so that the feeder transfers the plastic particles loaded into the juice to the front end of the screw and heats the same. Under the effect of plasticizing the material. When the molten material accumulated on the front of the barrel is equal to the set injection volume, a certain thrust is generated on the screw, so that the screw accurately measures the melted part and can appear on the display, thereby ensuring accurate pre-molding amount. (5) Precision Injection Molded Film, Design and Manufacturing Technology of Blow Mold The design and manufacture of precision blank molds and blow molds are prerequisites for obtaining precision containers. Therefore, in the design of the parison mold blow molds, the shrinkage rate of the plastic raw materials should be considered, and the factors affecting the accuracy of the mold structure design should be taken into account to minimize these factors. These factors are roughly the size of the raw material shrinkage, the distribution of shrinkage, the size of the injection molding parison and injection port, the mold temperature control pipe and blow mold cooling water distribution, as well as the choice of mold materials.

With the development of the plastics industry, plastic container products have been used more and more in food packaging. On the supermarket shelves, we can often see various beverages, mineral water, cooking oil, fresh milk, yogurt, soy sauce, etc. Most of them are packed in plastic containers. At present, the main materials used for manufacturing plastic packaging containers include: PET, PC, and PE. In the second quarter of 2010, the Shanghai Quality Supervision Bureau organized relevant quality inspection agencies to carry out special supervision and spot checks on the food plastic packaging containers in the city's production areas. A total of 79 products were spot-checked. The inspection items included sealing performance, drop performance, suspension test, and piles. Code test, evaporation residue, sensory, Pb, potassium permanganate consumption, decolorization test, etc. Of the 79 products that were spot-checked, 78 were qualified, and one type of polyethylene blow barrel was damaged after the drop test, and the drop test failed. The overall spot check rate was 98.7%, and the overall product quality was good.

Plastics used to make plastic cups in daily life are made of PET, PP, PE, PC, etc. How can I choose a healthy cup? What is the material of the plastic cup ? Everyone knows the cups of different plastic materials by identifying the number at the bottom of the cup. Let's take a look! How to distinguish the plastic water cup what material is good? No. 1: PET polyethylene terephthalate Common mineral water bottles, carbonated beverage bottles, etc. Heat resistant to 70 ° C is easy to deform, and there are substances harmful to the human body. After 10 months of plastic products, the carcinogen DEHP may be released. Do not put in the sun in the car; do not pack alcohol, oil and other substances. PET cups are commonly used in making coffee cups. Their transparency is relatively high. They are suitable for cold drinks, such as Starbucks and other chain stores. In addition, PET is used for beverage bottles. For example, Pepsi and mineral water bottles are made of PET. When hot water is installed, it will secrete substances harmful to human body such as bisphenol A. No. 2: HDPE high density polyethylene Common white medicine bottles, cleaning products, bath products. Don't use it as a water cup, or use it as a storage container for other items. Cleaning is not thorough and should not be recycled. No. 3: PVC PVC Common raincoats, building materials, plastic film, plastic boxes, etc. Excellent plasticity, low price, so it is very common to use, can only heat 81 ° C. High temperature is easy to produce bad substances, rarely used in food packaging. Difficult to clean and residue, do not recycle. Do not buy if you have a drink. No. 4: PS polystyrene Common bowls of instant noodles, fast food boxes. Can not be placed in the microwave to avoid release of chemicals due to excessive temperature. After acid (such as orange juice) and alkaline substances, it will decompose carcinogens. Avoid packing hot food with a snack box. Don't use a microwave to cook bowls of instant noodles. PS plastic cups are generally used to hold cold drinks, like ice cream, etc., high temperature is easy to produce and return material. No. 5: PC other classes Common kettles, space cups, and bottles. Department stores often use water cups of this kind as gifts. It is easy to release the toxic substance bisphenol A, which is harmful to the human body. Do not heat when using, do not expose to direct sunlight. Understand the knowledge of plastic water cups, in daily life, when buying plastic cups, you can first look at the raw materials used in the cups, and also go to the regular manufacturers to buy.
