What's the difference between ordinary plastic bags and degradable plastic bags?

1, degradable plastic bags (that is, environmental protection plastic bags) with different materials are made of polymer materials such as PLA, PHAs, PBA, PBS, and non-degradable traditional plastic bags are made of PE plastic. ?

2. Degradable plastic bags with different production standards must meet the national standard GB/T2 166 1-2008, which has reached the environmental protection standard. Traditional non-degradable plastic bags do not have to meet this standard. ?

3. Degradable plastic bags with different decomposition time can generally be decomposed within one year, while Olympic environmental protection plastic bags can even be decomposed after 72 days of abandonment. Non-degradable plastic bags take 200 years to degrade.

4. Grange whitening fully degradable plastic bag is a traditional process, which can be completely degraded into air, moisture, organic matter and other harmless substances in a short time by adding degradable masterbatch.

Extended data:

Non-degradable plastic bags are harmful to human body;

1. The main raw materials of non-degradable plastic bags are polyethylene and polyvinyl chloride. When people come into contact with vinyl chloride, there will be symptoms such as wrist and finger edema, skin sclerosis, spleen enlargement, liver injury and so on. ?

Non-degradable plastic bags seriously affect our health. When the temperature reaches 65℃, using them to hold food will produce harmful substances, which will cause damage to human liver, kidney and central nervous system.

Non-degradable plastic bags are harmful to the environment;

1. If the non-degradable plastic bag is buried underground, it will take about 200 years to rot, which will have a bad influence on the soil pH and worsen the soil environment. If livestock eat plastic film, it will cause digestive tract diseases and even death.

2. Non-degradable plastic bags pose a threat to the survival of animals. Disposable plastic bags discarded on land and in the sea are swallowed by animals as food, resulting in animal death.
