1. The research and development of recyclable green packaging materials

Packaging waste regulations vary, but there is a common principle: to encourage less use of raw materials. Should try to use the same material in the packaging design,detachable material can coexist, and tend to use simple, easily recycled materials. Meet the packaging functions under the premise of minimizing the amount of garbage generated, thus rendering lightweight packaging film trends.

2.Research on biodegradable plastics technology biodegradable plastics are generally divided into biodegradable plastics, optical and biodegradable plastics / light degradable plastics. Variety of domestic R & D has covered photo degradation, biodegradation light, light Oxo-biodegradable, biodegradable high starch content type, high calcium carbonate filled light oxidative degradation, biodegradable and other categories; biodegradable plastics in packaging applications of , it has spread in common packaging film, shrink film, shopping bags, garbage bags, etc., for improving the quality of the environment has played a positive role. From the protection of ecological balance, the researchers completely biodegradable plastic is imminent;especially edible powder or inorganic mineral filled, high quality, low-cost biodegradable plastics are biodegradable plastics is currently an important research topic.

3. The edible packaging film is a natural edible substance (such as polysaccharides,proteins, etc.) as raw materials, through the interaction between different molecules and the formation of a film having a porous network structure. Such as chitosan edible packaging film, packaging films of corn protein, modified cellulose membrane composite edible packaging edible packaging film, edible film can be applied to a variety of instant food packaging in the food industry should be It has a huge market.

4. The water-soluble plastic packaging film of water-soluble plastic packaging film as a novel green packaging materials,in Europe, Japan and other countries are widely used in a variety of product packaging, such as pesticides, fertilizers, paints, dyes, detergents, water treatment agent, mineral additives, detergents, concrete additives,photographic chemicals and gardening care chemical reagents.

The use of high strength high barrier plastic can not only improve protection of food, but also in the packaging when the same amount of food can reduce the amount of plastic, and even can be reused. Now commonly used in high-barrier materials are aluminum foil, nylon, polyester, polyvinyl, chloride and the alike. With food to improve the protection requirements, better barrier ethylene vinyl alcohol copolymer, polyvinyl alcohol, began to apply.
