The paper, the problem of the breakdown of PE composite membrane | | food industry information packaging manufacturers

Appearance of plastic goods is the most important invention in human history, it brings great convenience to the human time, the emergence of PE composite membrane for electronic transport, food, industrial supplies a lot of security function, PE composite film products in the field of precision instrument applied to again and again, even with the high speed of plastic goods, the environmental protection question is also on the agenda, headed by PE composite film, film and other plastic products of plastic waste serious impact to the environment, our days was also named white waste plastic waste, become over the past twenty years, is bad for the environment of one of the primary pests. PE composite membrane has been widely used in industrial areas, industrial products need to be serious, it is also about the quality of the protective film features more needs. PE composite membrane in the sixties and seventies arose in Europe and the United States in some developed countries, after continuous expansion, is now widely used and mechanical, surface, electronics, shipbuilding, construction materials, automobile manufacturing, etc. In our environmental protection question increasingly pay attention to, PE composite film and other plastic goods must to green products, no pollution, easy to decompose, recyclable away, talent for direct use and direct use of choice. In order to properly dispose of protective film waste problem, chemists is changing the protective film itself planning, so as to throw away the protective film completely decomposed in the not too long. Is in the eighty s brought about the rise in our country, after constantly of the symposium, also has come a long way. At that time, decomposable PE composite membrane, etc. There are two types of plastic. One kind is light type, this type of plastic in the process of manufacturing, every distance on the polymer chain is added the photosensitive groups. Such plastic under artificial light is a safe, secure, but under the irradiation of the sunlight, photosensitive groups can absorb satisfactory energy and make the polymer chains in the craze, hence leading to the decomposition of plastic. Another kind is biodegradable plastic, this kind of decomposable plastic is introduced into some groups on polymer chain, so that the air, soil microbes can make polymer chain cracking into pieces, then its complete decomposition.
