Under certain environmental conditions, after a certain period of time and one or more links, the structure of the biodegradable packing bag has changed and some other properties have been lost, such as the packaging that has undergone structural changes, mechanical properties, and appearance changes. The bags are called biodegradable packing bags.
There are many types of biodegradable packing bags, such as biodegradable flat bags, handbags, self-adhesive bags, vest bags, etc. Biodegradable packing bags are fully biodegradable, can be degraded into water and carbon dioxide, and have no impact on the environment. Biodegradable packing bags are soft and smooth to the touch, and have color differences such as light yellow and white. It has a wide range of uses, such as clothing self-adhesive bags, flat bags, biological express bags, vest bags, disposable product packaging bags, etc.
The film of biodegradable packing bags is made by blending and modifying polybutylene succinate (PBS) and polylactic acid (PLA), which has good comprehensive properties. Biodegradable packing bags can be degraded into water and carbon dioxide within three months under aerobic composting conditions, and the degradation conditions comply with EN13432 and ASTMD6400 standards. The advantage of biodegradable packing bags is that they are harmless to the environment. With the development of environmental protection, biodegradable plastic bags have become a trend. Biodegradable packing bags can be decomposed into water and carbon dioxide within 180 days under composting conditions.
Traditional plastic bags cannot be degraded in the natural environment, even for hundreds of years; even after degraded chemical components will still remain in the soil and water, causing harm to them.
