The difference between degradable packaging bags and fully degradable packaging bags

The difference between biodegradable packaging bags and fully biodegradable packaging bags:
Fully degradable pouches are bioplastics that naturally decompose under the action of microbial organisms and can completely decompose in a composting environment within a specific time (usually 6 months).

Degradable packaging bags can be divided into two types from the difference in raw materials and decomposition factors:
One is a plastic bag made of polyethylene plastic, mixed with starch, it is worth mentioning that it degrades only the starch part, and after decomposition, the plastic becomes fragments, which is not conducive to recycling.
The other is a plastic bag made of polyethylene plastic, mixed with photodegrader and calcium carbonate and other mineral powders, also known as photodegrading plastic bags, which are decomposed under the action of sunlight.

From the perspective of environmental protection, it is not recommended to use degradable bags with polyethylene, because after degradation, it becomes fragments, which is more unfavorable for recycling and more polluting to the environment.
