The invention of plastic bags has indeed facilitated people's life to a great extent, but it has promoted environmental pollution to a certain extent. The birth of environmental protection plastic bags is precisely to solve the serious problem of pollution. So, what is the material of the environmental protection plastic bag? Here is a brief introduction.
First, the main materials of plastic bags commonly used in life are polyethylene (PE), polyvinyl chloride (PVC), etc. the former is mainly used in food bags and daily shopping bags; The latter is mainly used in printed matter, such as book packaging and film. In order to facilitate people's life on the basis of environmental protection, environmental protection plastic bags have been born.
Secondly, the materials of environmental protection plastic bags are mainly their own PE, PVC, LDPE, etc. but due to their characteristics of being difficult to degrade, some materials are added to the production of environmental protection plastic bags to help them decompose and degrade. Commonly added materials include: starch or modified starch, cellulose, photosensitizer or other biodegradable agents.
Finally, on the basis of ensuring the original non-toxic and tasteless characteristics of the plastic bags, the added materials of the environmental protection plastic bags can help them to degrade and decompose themselves in the outdoor for about 2-3 months, thus alleviating the pressure of environmental pollution to a great extent.
The main material of environmental protection plastic bags is to add some additives to help the degradation of raw materials, which can promote the decomposition of plastic bags. Under the premise of ensuring the environment, we can better provide people with convenient life.
