Plastic packaging materials, biodegradable development

Since the 20th century 50 - Since the 60 s plastic gradually into the packaging materials, plastic packaging materials for its variety, superior performance, easy processing, low cost and people's favour, plastic packaging materials after paper, in the rapidly developed into packaging materials, the most widely application, one of the main varieties are the most. Use of plastic packaging materials, improve the quality of people's life, promote the development of agriculture and industry, has played a huge role, but with the first application of plastic packaging materials, its a large amount of waste produced, also be a big burden for society, plastic products are usually famous for its stable performance, not easy to decompose rottenly, it could have been a strong point of material. But when its wastes into the environment, accumulate over a long period continue to increase, became a big burden on the environment, in the process of the development of plastic packaging industry, people gradually know the seriousness of this problem and gradually achieve harm the consensus of the natural environment, the governance of plastic waste, the development of degradable plastics as a development one of the key work for the sustainable development of plastic packaging materials. Plastic packaging film is one of the biggest advantages of less raw material consumption, low cost, has strong competitiveness, economic and development speed, is one of the most popular varieties of plastic packaging materials, from the perspective of environmental protection, plastic film class packaging materials compared with other packaging materials, reduction of advantage is obvious, in terms of reduction of point of view, it is the most varieties of environmental protection, but also because of plastic film bag packing single less consumption of raw materials, although in theory discarded plastic bags can be recycled, but the economics of recycling, under the condition of market economy, who also don't want to do lose money buying and selling of plastic film waste packing material, natural is one of the hardest to realize recycling of packaging materials, additional film bag is not easy to clean, and therefore is not easy to reuse, therefore, from the reuse, recycling and biodegradable's point of view, the traditional non-degradable plastic bags, and adaptability is poor environmental protection products, this chapter reflects the development of biodegradable plastic film, improve on plastic film products, this paper discussed the applicability of environmental protection.
