The degradable plastic bag should have two aspects: on the one hand, it is
made of natural materials that can be reused; On the other hand, it is not easy
to leave solid waste in the natural environment after it is damaged, causing
adverse effects on the environment (or the harm to the environment is very small
compared with other materials). Generally, it is difficult to degrade after
being discarded in the environment, even if a small part of it is decomposed, it
will also cause harmful substances. It is a consumable in daily life, and our
country consumes a lot of plastic shopping bags every year.
The good transparency, heat resistance, high tensile strength, impact
strength, rigidity and toughness of degradable plastic bags are almost the same.
Small thermal shrinkage, good adhesion with paper. The printing ink has good
printability and can protect the surface of printed matter It is resistant to
friction, moisture, light, water and dirt. It is a friendly packaging bag for
human and environment, and is of great significance to ecosystem and human
health. This kind of packaging can be dissolved and rebuilt in a relatively
limited time, and is a commodity of the concept of sustainable development. At
this stage, many terminal equipment companies have already applied such plastic
packaging bags.
