The implementation of green food industry packaging imperative

At present, China food packaging materials, plastic applications for more than 50% of the total amount of food packaging materials, ranking first in all kinds of packaging materials, the vast majority of plastic food packaging can not be recycled, resulting in environmental damage. Therefore, we should vigorously develop green packaging. The variety of food packaging has its own characteristics. Not long ago, held in Tianjin, \”the whole industry chain of food packaging Third Security Forum\”, the participants discussed in detail on biodegradable plastics, cold chain packaging, smart packaging and food safety issues. Not long ago, the United States sponsored by the Lion Media Group, China Packaging Federation in association with the International Chamber of Commerce and plastic packaging Packaging International Electronic Commerce Chamber of Commerce supports the \”Third food packaging industry chain Security Forum\” held in Tianjin. Delegates were described in detail on the different characteristics of various packaging and future trends. 食品行业推行绿色包装势在必行 data – shocking the implementation of green packaging imperative Jin Hui Siu Lung hi-tech Co., Ltd. President Liya Juan to share with you a set of data: China\’s food packaging metal packaging accounted for 8% -10%; paper packaging 32% -35%; glass packaging 4-6%; other packaging about 4%; more than 50% of plastic packaging. At present, China food packaging materials, plastic applications for more than 50% of the total amount of food packaging materials, ranking first all kinds of packaging materials. Most of plastic food packaging can not be recycled. ASD\’s latest research report shows that China\’s average per person per day with all kinds of plastic bags 5-8, the vast majority of disposable plastic bags, Chinese consumption of disposable plastic bags each year about 100 million tons, when coupled with other food packaging, conservatively estimated at 200 million tons. At present, National Express daily volume reached 60 million, annually 17 billion m using adhesive tape, plastic bags usage reaches 8.2 billion. Expected in 2020, National Express will reach 50 billion, 20 billion plastic bags, bubble cushioning bags 7 billion. Three takeaway from the current data platform, the average daily order of about 7 million or so single, every single addition to the three plastic lunch boxes, one to two layers of plastic bags, it also includes disposable chopsticks, plastic spoons, soup cup , straws, disposable food items abandoned after these are generally not recycled into the system. It is estimated that China now only disposable plastic lunch boxes and all kinds of foam packaging on the annual consumption of nearly 50 million tons.Look around the world, each year about 800 tons of plastic garbage into the ocean, China accounted for nearly one-third. Plastic waste floating in the world\’s oceans, the oceans are currently more than 150 million tons of plastic waste, covering an area of ​​88%. 90% of the birds died due to eating plastic, thus causing global annual economic losses of at least $ 13 billion. According to the data, the total amount of food packaging accounts for about 60% of the entire packaging industry. The world\’s annual output of plastic packaging amounted to 80 billion to $ 120 billion, but 95% of these plastic packaging for single use only. \”35\”, the total stock pile of plastic waste has reached 8.8 billion tons, these waste plastics processing cost is 55 times the cost, such as natural decay takes more than 200 years. How to deal with plastic waste? Incineration of waste plastics will produce large amounts of dioxins and other toxic gases, causing secondary pollution and the greenhouse effect. Landfill is the main method of waste disposal in most cities, garbage deposit a total of more than 75 acres of land occupation, annual economic losses of 300 million yuan, now we have tens of thousands of suburban landfill closure. Plastic natural degradation takes more than 200 years, precipitation additives can contaminate soil and groundwater. Non-degradable plastic packaging of heavy use, causing serious white pollution, ecological environment has brought great irreparable damage. It kindled a glimmer of hope that the domestic ban plastic policy easing pressure plastic waste, also in the implementation of the global ban plastic, countries are vigorously promoting green packaging. biodegradable plastic packaging market has great potential Jin Hui Siu Lung tech Co., Ltd. Liya Juan said that in recent years, biodegradable plastics demand continues to grow. 2016–2019 annual demand for biodegradable plastic packaging market will maintain double-digit annual growth rate, by 2019 the global biodegradable plastic packaging market value of more than $ 8.415 billion. According to this forecast, food and beverage packaging will be the largest of biodegradable plastic main application areas for food packaging biodegradable plastics accounted for more than 70%. In recent years, domestic and actively explore and study of biodegradable compostable plastics, of PBAT (polybutylene adipate / terephthalate), PLA (polylactic acid), PBS (polybutylene succinate), the PHA ( polyhydroxy fatty acid ester), of PHBV (polyhydroxybutyrate – valerate) came into being, which, PBAT due to the better ductility and elongation at break, good processing performance, as great potential for development of new environmentally friendly materials. New biodegradable compostable plastic solve white pollution at its source. It has the same performance as traditional plastics; alternative to traditional plastics processing into a variety of products, effective against white pollution; can promote economic growth and ecologically sustainable development. In the case of reduction can not be used, and is not suitable for secondary usage recovered PBAT best biodegradable plastics film packaging material embodiment. Guangzhou Miao Tak New Materials Co. representatives of the explanation for the definition and application of biodegradable materials. Completely made of biodegradable plastics is a polymer having biodegradability by microbial fermentation of natural or synthetic polymer (such as starch, cellulose, chitin) or agricultural have to biobased materials absolute body, degradation to carbon dioxide and water Wait. Destructive biodegradable plastics include starch modified (or filled) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, and PS as the plastic body, partially degraded, plastics fragmentation. Currently, application of biodegradable material, simple application including shopping bags, garbage bags, and other plastic sheeting; moderate applications including lunch boxes, electronic components, easy packing applications; 3D depth applications including printing, printing the composite film / hard plastic and other fine packaging, medical equipment and so on. China\’s market being dominated by simple application. temperature controlled packaging products with high added value business opportunities of the early Jiangnan University transport packaging and cold chain logistics Research Professor Wang Jun said the package would do two things, electrical products packaging for damage control, food packaging in order to maintain or extend shelf life. Three major trends in food packaging for the whole nutrition, full quality, full security. Full nutrition – from the farm to the consumer; the whole quality – from the source to the end; full security – the security of raw materials, manufacturing safety, logistics, security, food safety. Wang Jun said that the packaging of industrial output value in 2002 more than 2,500 billion yuan in 2015 exceeded 150 trillion. The overall level of China\’s packaging industry started late, weak technology, small scale, low R & D investment, technological innovation serious shortage of capacity, a 20-year gaps with the developed countries. The current comprehensive cold chain circulation rate of 19%, while the cold chain circulation rates in developed countries the United States, Japan and other more than 85%. Cold chain logistics and home delivery customersGroups can be divided into B2B and B2C markets. 2014, Commerce Department data showed, B2B accounted for the overall market 3/4, B2C accounts for a quarter of the overall market. B2C e-commerce market is affected by the development, from 2012–2014 years, 3 years, its average annual growth rate has reached 80% -120%. 2015, cold chain logistics and home delivery market reached 4 billion yuan. Cold chain target temperature sensitive products such as food, drugs, biological products, fresh. Cold chain logistics in two ways: active and passive cold chain cold chain. Active cold chain is using active refrigeration equipment cold storage, refrigerated trucks, which is characterized by stable and reliable, but only for the storage and transportation of large quantities of products are generally used for B2B. Passive passive cold chain storage technology incubator, insulation bags. Its characteristics are small and flexible, can be applied to products and scattered \”last kilometer\”, generally used for B2C. Packaging temperature phase transformation by absorbing excess heat coolant. Reducing by heat exchange outside the packaging insulation material. Packing container outer surface area of ​​the temperature as low as possible; phase transition temperature of the coolant meets product requirements; coolant regenerator long time. For the main problems of insulation packaging materials, Wang believes there are three major problems, first of all, the \”white pollution.\” He said the petroleum-based foam material is currently the most cost-effective insulation material, but it can not degrade naturally has limitations in terms of export products. Second, the high cost. PU and airgel has excellent insulation properties, but its raw material and processing costs are too high, severely restricting its application. Third, the recovery problem. Currently Baowenrongqi popular for one-time use, there is a considerable waste of resources. Packaging direction on insulation materials, Wang said biodegradable foamed material is a petroleum-based direction, bio-based insulation material biomass raw materials, the foaming process using microwave new, environment-friendly development of new insulation material. Further, collapsible, returnable and recovery mechanisms are incubated Baowenrongqi a direction of the packaging material. Currently coolant applications are still some problems. First, the phase transition temperature is too narrow. Currently low temperature coolant main phase transition temperature of -18 ℃, 0 ℃ -2 ℃, and higher costs coolant 2 ℃ -10 ℃ desired bulk fruits and vegetables and low latent heat. Second, slow cool storage. Since the coolant is mainly regenerator cold static storage, thermal conductivity and the coolantThe lower the number, resulting in low heat exchange efficiency, slow speed regenerator affect efficiency. Third, the cost is too high. Due to the current coolant recovery mechanism is not perfect, resulting in temperature-controlled packaging costs remain high, not widely used. R & D focus and direction coolants are threefold: First, to develop high-performance coolant 2 ℃ -10 ℃; the second is the rapid coolant storage technology research and development. By increasing the coolant thermal conductivity, and the development of new technology to improve the dynamic charge cold coolant speed regenerator. Third, establish recycling mechanism coolant. Wang believes that challenging packaging temperature control, temperature control packaging lack of basic data, the standard is almost empty, the last kilometer and costs, transport efficiency, recycling reuse issues need to be resolved. The problems and opportunities coexist, high value-added products packaging business opportunities in the early temperature control, agricultural commodities passive cold chain packaging is still far away. intelligent clever packaging help food safety United States Lion Media Group on behalf of a large number of reference data describes the relationship of smart packaging and food safety. According to a research report, the current cost of fraud accounted for 2% of global economic output, or about $ 1.8 trillion a year for fraud. Even more shocking is that fraud it is growing at a rate of 15% per year extensions. Where consumer goods accounted for more than 46% of the fraud trade, including food and beverages, cosmetics and other items. To maintain brand equity, security and traceability measures implemented in the package will become crucial. With the arrival of the 4.0 concept of industrial, food packaging is also gradually moving towards high-end, smart packaging began to enter people\’s vision. Intelligent packaging Intelligent where? The first performance is intelligent food safety issues, smart packaging can detect the quality of the food, or is an effective anti-counterfeiting, safeguard the interests of consumers to the greatest extent, and product traceability function. United States Annette (Allied Market Report) released the 2020 food and beverage anti-counterfeiting packaging market forecast report, 2020, in the technical aspects of anti-counterfeiting packaging, hologram anti-counterfeiting technology will continue to maintain its dominant position, but RFID (RFID radio frequency identification ; radio Frequency identification abbreviation; radio frequency identification technology; commonly known as RFID) technology and two-dimensional bar code, especially code security will grow rapidly. At present, the entire hologramA security account for about two-thirds share of the market, the future is still dominant. Future, RFID technology will be 20.4% annual rate of rapid growth. Security barcode traceability contribute to maintaining the integrity of the supply chain, there is great potential for food security in traceability.
