The invention of plastic bags has indeed facilitated people's life to a great extent, but it has increased environmental pollution to a certain extent. The birth of environmentally friendly plastic bags is precisely to solve the serious problem of pollution. So, what is the material of environmentally friendly plastic bags? Here is a brief introduction.
First of all, the main materials of plastic bags commonly used in life are polyethylene (PE) and polyvinyl chloride (PVC). 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 came into being.
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, environmental protection plastic bags have added some materials to help them decompose and degrade. Commonly added materials include: starch or modified starch, cellulose, photosensitizer or other biodegradable agents.
Finally, the added materials of environmental protection plastic bags are mainly on the basis of ensuring the original non-toxic and tasteless characteristics of plastic bags, which can help them degrade and decompose themselves in about 2-3 months outdoors, which will alleviate the pressure of environmental pollution to a great extent.
The main material of environment-friendly plastic bags is to add some additive raw materials to help degrade, which can promote the decomposition of plastic bags. On the premise of ensuring the environment, better provide people with convenient life.
