In China, with the implementation of mandatory waste classification in
recent two years, biodegradable materials have gradually become a popular
concept. What are biodegradable materials and in what fields? How to distinguish
this material?
What is the biodegradable material and how to identify it?
The development of plastic bags towards green is closely related to
people's concern for environmental protection. Since the 1970s, many countries
have begun to develop green plastic bags. Since polyethylene and polypropylene
are mainly polyolefins, they cannot be decomposed in a short time. Finally,
scientists synthesized a series of polyester materials that can be decomposed by
microorganisms, and green materials extracted from some renewable resources
(such as straw, bagasse, corn starch, etc.) to make truly biodegradable green
plastic bags.
The biodegradable packaging bag must meet three conditions:
1、 It must be able to be completely degraded to produce carbon dioxide and
water;
2、 It must be completely degraded within 180 days under industrial
composting conditions;
3、 It is non-toxic after degradation and has no impact on the
environment.
Biodegradable materials have been widely used in the customization of
packaging bags, which can be treated in composting plants and become organic
fertilizers after 30-45 days. Since the 1990s, western countries have begun to
use biodegradable shopping bags and kitchen garbage bags.
Due to the short time of using biodegradable packaging bags in China, many
customers who need customized packaging bags do not know how to identify
biodegradable packaging bags. As this kind of packaging bag has no obvious
difference from ordinary plastic bags in appearance, a series of standards have
been issued in the world: ISO14855, EN13432, ASTM-D6400.
