Health hazards of plastic packaging
Plastic packaging materials have the advantages of light weight, high strength, good impact resistance, transparency, moisture resistance, beauty, stable chemical properties, good toughness and corrosion resistance. They have widely replaced metal, wood, paper, glass, leather, etc. in the packaging field. Therefore, plastic packaging has played an irreplaceable role in reducing the pressure on resources and energy in our country.
However, plastic packaging materials have a fatal weakness, that is, their natural degradation time is long, some as long as 100 years. The non-degradability of plastic causes its waste to exist for a long time. Moreover, plastic packaging waste is often discarded after consumption. Therefore, plastic packaging waste has become an increasingly prominent environmental problem, forming the so-called “white pollution”, which puts a lot of pressure on the human living environment. Therefore, the impact of plastic packaging waste Recycling is imminent.
