Plastic shopping bags are packaging materials made from polyolefin as the main raw material and the appropriate addition of other substances.Polyolefin is mainly polyethylene, commonly known as soft glue, the main products include low density polyethylene or high pressure polyethylene (LDPE), high density polyethylene or low pressure polyethylene (HDPE), linear low density polyethylene (LLDPE) and Metallocene polyethylene (MLLDPE) four categories.To reduce its cost, most companies have added about 30% calcium carbonate to fill plastic shopping bags, which do not emit toxic gases when burned at the dump. For every 1 tons of plastic produced, 3 tons of oil are consumed. China's annual waste plastic entering landfills with domestic waste accounts for 3%-5% of the weight of landfill waste, most of which is waste plastic shopping bags, especially ultra-thin plastic bags with a thickness of less than 0.025 mm.
Waste plastics are not easy to degrade under natural conditions, resulting in long-term and potential ecological environment problems. First, waste plastic packaging mixed in the soil, easy to cause soil compaction, affecting crops to absorb nutrients and water, resulting in crop reduction; second, waste plastic packaging abandoned in land or water bodies, by animals as food swallowed, resulting in animal death incidents are common; third, waste plastic mixed into domestic waste is difficult to deal with, Household waste mixed with waste plastics is not suitable for composting, and sorted waste plastics are difficult to utilize because they cannot guarantee quality.
Based on the premise of protecting the environment, environmental shopping bags appear in front of everyone.
