The pollution of flexible packaging should not be underestimated

old man Zhang in Dun village, Xinfu District, Xinzhou City, Shanxi Province, has really had a good time in recent years. Apart from other things, the family of six people drink a packet of milk every day. Whether it's precision: ≤ 0.5% pure milk, breakfast milk, or drinking milk at night, they all choose soft packaging. Only their family drinks 180 bags of milk every month, but the soft packaging after drinking is neither recycled nor degradable, and it pollutes the environment after being thrown on the garbage heap

nowadays, whether dairy products, convenience foods, children's food, or even condiments, cold drinks, most of them use soft packaging. Flexible packaging is popular with consumers because of its low cost, easy to carry and low price

according to the investigation of Xinfu District Industrial and commercial branch of Xinzhou City, Shanxi Province, now the discarded flexible packaging has become a source of environmental pollution, because most of the flexible packaging choose plastic as the raw material, so it is not easy to degrade and rot, and no one recycles it. In case of wind and rain, it will drift to rivers, fields, orchards and vegetable fields. Therefore, how to curb the pollution of flexible packaging has become an urgent event. First of all, biodegradable plastic should be gradually used as flexible packaging materials. Degradable plastic refers to a kind of plastic whose chemical structure changes at a specific time and environment. Degradable flexible packaging plastic not only has the functions and characteristics of traditional plastics, but also can be decomposed in the natural environment with the same yield and melt quality through the action of ultraviolet rays in the sun or microbials in soil and water after completing its service life, and finally return to nature in a non-toxic form

secondly, we should organize the recycling of flexible packaging. It is reasonable to say that the flexible packaging based on plastic still has a certain comprehensive utilization value after its service life is completed. Therefore, it is 100 times better to entrust a waste acquisition station or manufacturer to recycle, and then conduct centralized treatment or waste utilization, or generate electricity by heating, than to litter everywhere

thirdly, the concept of flexible packaging development should also be changed. In recent years, the glutinous rice paper used in candy packaging and the corn baking cup used in ice cream packaging are all very typical edible packaging. Among the synthetic edible packaging films, the familiar one is pullulan resin. Its aqueous solution can be made into a film with a thickness of 10 microns after drying or hot pressing, which can be used as food packaging. Not long ago, a newly validated Solvay tecnoflon pl855 fluororubber (FKM) developed by the packaging research institute in Wuhan also gives fasteners better chemical resistance and high temperature resistance. The edible inner packaging film is a high molecular material reported by the people connected with glucose, which has the characteristics of edible, degradable, colorless and transparent, and good oxygen isolation. As a food packaging film, its right angle tear strength, mechanical strength and light transmittance can meet the standard of plastic packaging excellent film

in order to solve the pollution of flexible packaging, we must carry out comprehensive development, take multiple measures, and cooperate with scientific research, environmental protection, packaging and other institutions. Only in this way can we make flexible packaging more environmentally friendly
