Biodegradable plastics can completely degrade the plastics that need to be decomposed for 100 years in a short time, which makes outstanding contribution to environmental protection.
Plastic bags are used to exist in people's lives. No matter on the street or in the kitchen, plastic bags can be seen everywhere. Urban people eat breakfast, and the wide use of plastic film in the field greatly facilitates people's daily life, but also brings a huge disaster to the environment.
If the bag is buried in the ground, it will take about 100 years to decompose, and the soil will be seriously polluted; burning will produce harmful smoke, resulting in serious secondary pollution.
Many countries and regions have banned or restricted the use of plastic bags. San Francisco City Council passed a bill banning supermarkets, pharmacies and other retailers from using plastic bags. In cities such as Los Angeles, the government has begun recycling plastic bags. Plastic shopping bags or paid use are also prohibited in some places, including Canada, Australia and Brazil.
As the pollution caused by plastic is obvious, many marine organisms are suffocated by plastic, some of which are placed on their bodies and deformed. These tragedies happen almost every day. Therefore, degradable plastics have become a trend!
