What is the difference between degradable plastic bags and traditional
plastic bags? It can be said that the production raw materials of the two are
very different, because the materials are different, so they have different
characteristics. The components of raw materials for the production of
degradable plastic bags not only use safe and healthy corn starch granules as
basic materials, but also add some components that can promote
decomposition.
Composition of production raw materials
In addition to corn starch, there are non-toxic and safe degradants,
modified starch and other cellulose, photosensitizers, etc. The addition of
these ingredients can accelerate the rate of biodegradation. Some
environment-friendly plastic bags will be gradually decomposed under light,
while others will be gradually decomposed in contact with biological flora. The
decomposition conditions required are different depending on the added
degradants. In terms of the use of production materials, the
environment-friendly plastic bags are non-toxic materials, and toxic materials
will not be added to the production process.
How long will it take to decompose
The decomposition time of traditional plastic bags is at least more than
200 years, while the degradation time of this new environment-friendly
degradable plastic bag is different due to different degradants. Some require 90
days to be decomposed under certain conditions, while others require half a year
to be decomposed. It should be noted that plastic bags that can be decomposed
will only be decomposed under certain time and conditions.
The composition of raw materials for the production of degradable plastic
bags is briefly introduced here. Because of the different ingredients, the
quality and characteristics of the finished products are different. The
toughness and durability of degradable plastic bags are much higher than those
of traditional plastic bags.
