First of all, performance can not be completely replaced, such as meat, seafood and other oily goods, using paper bags and cloth bags can not solve the problem well. Secondly, excessive use of paper bags will lead to excessive deforestation, damage the ecological balance, and cause catastrophic and unacceptable harm to the environment.

　　1.研究开发可回收利用的绿色包装材料。包装废弃物法规因地而异，但有一个共同的原则：鼓励少用原材料。在包装设计上应尽量使用同一材料、可分离可共存的材料并趋向于使用结构简单、容易循环再生的材料。在满足包装功能的前提下，尽量减少垃圾的产生量，从而呈现包装薄膜轻量化发展趋势。

　　1. Research and develop recyclable green packaging materials. Regulations on packaging waste vary from place to place, but there is a common principle: to encourage less use of raw materials. In the packaging design, we should try to use the same material, separable and coexistent material, and tend to use the material with simple structure and easy recycling. On the premise of satisfying the packaging function, reduce the amount of garbage as much as possible, so as to present the development trend of lightweight packaging film.

　　3. The research of plastic degradable technology degradable plastics are generally divided into biodegradable plastics, photodegradable plastics and bio / photodegradable plastics. The varieties researched and developed in China have covered photodegradation, photodegradation, photodegradation, high starch content type photodegradation, high calcium carbonate filled type photodegradation, total biodegradation and other categories; the application of degradable plastic products in packaging has spread to ordinary packaging film, shrink film, shopping bag, garbage bag and so on, which has played an active role in improving environmental quality Use. In order to protect the ecological balance, it is urgent to study the fully biodegradable plastics, especially the high-quality and low-cost biodegradable plastics filled with edible powder or inorganic minerals.

　　4.研发焚烧回收热能或采用炼钢炉再利用塑料废弃物的研究开发焚烧回收热能是塑料废弃物再资源化的一个主要手段，也是治理塑料废弃物的更现实的选择。今后应研究开发塑料垃圾处理提供热能的有关设备，设计出使用更为简便、寿命更长、更低的设备，以加速我国焚烧回收热能和利用炼钢炉再利用塑料废弃物的研究开发。

　　4. Research and development of recycling thermal energy by incineration or recycling plastic waste by steel-making furnace; recycling thermal energy by incineration is a major means of recycling plastic waste, and also the most realistic choice for the treatment of plastic waste. In the future, it is necessary to research and develop the equipment related to the thermal energy provided by plastic waste treatment, and design the equipment with more convenient use, longer service life and lower price, so as to accelerate the research and development of recycling thermal energy by incineration and recycling plastic waste by steel-making furnace in China.

　　5.可食性薄膜可食性包装膜是以天然可食性物质(如多糖、蛋白质等)为原料，通过不同分子间相互作用而形成的具有多孔网络结构的薄膜。如壳聚糖可食性包装膜、玉米蛋白质包装膜、改性纤维素可食性包装膜及复合型可食包装膜等，可食性薄膜可应用于各种即食性食品的内包装，在食品行业应具有巨大的市场。

　　5. Edible film edible packaging film is a kind of film with porous network structure, which is made of natural edible materials (such as polysaccharide, protein, etc.) through the interaction between different molecules. For example, chitosan edible packaging film, corn protein packaging film, modified cellulose edible packaging film and composite edible packaging film, etc., edible film can be applied to the inner packaging of various ready to eat foods, which should have a huge market in the food industry.

　　6.水溶性塑料包装薄膜水溶性塑料包装薄膜作为一种新颖的绿色包装材料，在欧美、日本等国被广泛用于各种产品的包装，例如农药、化肥、颜料、染料、清洁剂、水处理剂、矿物添加剂、洗涤剂、混凝土添加剂、摄影用化学试剂及园艺护理的化学试剂等。

　　6. Water soluble plastic packaging film as a new green packaging material, water soluble plastic packaging film is widely used in the packaging of various products in Europe, America, Japan and other countries, such as pesticides, fertilizers, pigments, dyes, detergents, water treatment agents, mineral additives, detergents, concrete additives, photographic chemicals and gardening care chemicals.

　　7.进行循环经济型塑料发展相应的对策、法律、法规和制度的制订和实施办法的研究。目前，我国固体塑料废弃物分放的设施在上海市已经出现，但仍有很多人随意投放。相当多的地区、部门和企业，表现出只顾眼前利益的短期行为。

　　7. Focus on the research on the corresponding countermeasures, laws, regulations and systems for the development and implementation of circular economy plastics. At present, China's solid plastic waste separation facilities have appeared in Shanghai, but there are still many people who drop them at will. A considerable number of regions, departments and enterprises have shown short-term behavior of focusing only on immediate interests.

　　8.CT材料日本化学公司经过10年的努力，已研制成功符合环保原则的食品包装容器专用塑料CT。CT不仅耐高温，还有一个更突出的优点，就是它的功能与俗称"泡法沫塑料"的PSP塑料制品相仿，而其体积只相当于后者的1/4。这样在回收时避免了因体积庞大而产生的诸多麻烦，并为对环境的负面影响创造了极有利的条件。

　　8. After 10 years of efforts, CT materials Japan Central Chemical Company has successfully developed a special plastic CT for food packaging containers in line with the principles of environmental protection. CT is not only resistant to high temperature, but also has the most outstanding advantage, that is, its function is similar to PSP plastic products commonly known as "foam plastic", and its volume is only 1 / 4 of the latter. In this way, many troubles caused by large volume are avoided in recycling, and favorable conditions are created for eliminating the negative impact on the environment.

　　9.新型高阻隔性塑料包装材料新型高阻隔性塑料在国外已广泛应用，国内也已引进这项技术。使用高强度高阻隔性塑料不仅可以提高对食品的保护，而且在包装相同量食品时可以减少塑料的用量，甚可以重复使用。现在国内常用的高阻隔性材料有铝箔、尼龙、聚酯、聚偏二氯乙烯等。随着食品对保护性要求的提高，阻隔性更好的乙烯、乙烯醇共聚物、聚乙烯醇等也开始应用。

　　9. New high barrier plastic packaging material new high barrier plastic has been widely used in foreign countries, and this technology has been introduced in China. The use of high-strength and high barrier plastics can not only improve the protection of food, but also reduce the amount of plastic when packaging the same amount of food, and even can be reused. At present, the commonly used high barrier materials in China are aluminum foil, nylon, polyester, polyvinylidene chloride, etc. With the improvement of food protection requirements, ethylene, vinyl alcohol copolymers and polyvinyl alcohol with better barrier properties have also been applied.
