What are the types of biodegradable bags?

2021-11-24

Common degradable plastic bags can be divided into fully biodegradable plastic bags, destructive biodegradable plastic bags, and light-degradable plastic bags.


Fully biodegradable plastic bags are made entirely of bio-based materials, using PLA and PHA plastics, all of which can be biodegraded into carbon dioxide and water. Through the adjustment of the formula of the fully biodegradable plastic bag, it can be more suitable for the biochemical treatment process of urban organic domestic waste, so as to solve the problem of the need to actively break the bag when the current residential area throws away food waste bins. Suffering from personal hygiene problems.


Destructive biodegradable plastic bags currently mainly include starch-modified traditional petroleum-based plastics, which biodegrade the added starch and decompose them into smaller petroleum-based plastic fragments. Because microplastics are still produced after decomposition, which is not completely degradable, some countries have begun to ban oxidative biodegradable plastics.


Photodegradable plastic bags are bags in which photosensitive groups are introduced into the polymer backbone or photosensitizers, photoinitiators, etc. are added to the plastic to make traditional plastics have photodegradation characteristics.
