The meaning of non-degradable environmentally friendly plastic bags
The so-called non-degradable environmental protection plastic bags are ordinary polyethylene plastic bags. The degradable plastic bag is added with some special ingredients to make it easier to degrade.

The difference between non-degradable environmental protection plastic bags and degradable.

  1. Different materials, degradable plastic bags (that is, environmentally friendly plastic bags) are made of PLA, PHAs, PBA, PBS and other polymer materials. The traditional non-degradable plastic bag is made of PE plastic material.
  2. Different production standards, degradable plastic bags need to meet the national standard GB/T21661-2008, which has reached environmental protection standards. The traditional non-degradable plastic bags do not need to comply with this standard.
  3. The decomposition time is different. The degradable plastic bags can generally be decomposed within one year, and the Olympic environmental protection plastic bags can even start to decompose 72 days after being discarded. Non-degradable plastic bags will take 200 years to degrade them.

How to distinguish whether plastic bags are degradable?

If it is a plastic bag for food, it must also be printed with food safety. The qs mark is permitted and marked “for food”.
  2. For storage of degradable garbage bags, the shelf life of degradable plastic bags is only about three months. Even if they are not used, they will naturally degrade within five months. By six months, the plastic bags will be covered with “snowflakes”. use. Under composting conditions, even the newly produced degradable plastic bags can be completely degraded in only three months.

Why use degradable environmentally friendly garbage bags?
Biodegradable environmental protection plastic bags and plastic tableware are new types of biodegradable materials. Ordinary plastic bags and plastic tableware involve the problem of “white pollution”. They do not decompose underground and are harmful to crops, water sources, animal husbandry and humans themselves. After the degradable plastic products are buried in the soil, because the surrounding environment can meet the decomposition requirements, they will be completely decomposed into carbon dioxide and water, which belongs to the organic cycle and is harmless to the human body and the environment.
