Plastic packaging materials have the advantages of light weight, high strength, good impact resistance, transparency, moisture resistance, aesthetics, 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 Dry Casting Polished Surface Alumina Ceramic Wheel Roller energy in our country. However, plastic packaging materials have a fatal weakness, that is, their natural degradation time is long, some up to 100 years. The non-degradability of plastics causes its waste to exist for a long time. Moreover, plastic packaging waste is often discarded once consumed, so plastic packaging waste has become an increasingly prominent environmental problem, forming the so-called Dry Casting Polished Surface Alumina Ceramic Wheel Roller "white pollution", which puts a lot of pressure on the living environment of human beings. Recycling is imminent. Plastic cups are safer than paper cups
The plastic product code-named 5 can withstand temperature up to 130 degrees, can be filled with hot water and heated by microwave
The darker the straw, the less safe
Plastic straws are not suitable for drinking hot drinks
Plastic bowls and imitation porcelain bowls should Dry Casting Polished Surface Alumina Ceramic Wheel Roller be reduced
Do not use dark colored plastic bowls
Imitation porcelain tableware cannot contain acid
Code of mineral water bottle and pure water bucket "1"
Plastic bottles can store dry items
The water bottle with code number 5 is resistant to high temperature and can be reused
Qualified plastic lunch boxes are marked with "5" pp, and there is a vent hole on the lid. As plastics will add certain additives, the darker the color of the plastic, the deeper the added additives, or the more harmful substances remaining , Is not safe, and pp stands for polypropylene, which is not suitable for making plastic lunch boxes and is mainly not environmentally friendly.
