Difference between biodegradable and non-biodegradable plastic bags
With the strengthening of awareness of environmental protection, non-biodegradable plastic bags have slowly been eliminated, which is an important measure for environmental protection. But for the majority of consumers, there are many people do not know how to distinguish whether the plastic bags are biodegradable, the following wxtyler to introduce you to the difference between biodegradable plastic bags and non-biodegradable plastic bags.
Biodegradable plastic bags and non-biodegradable plastic bags are mainly different as follows.
1, the material is not the same
Biodegradable plastic bags made of PLA, PHAS, PBA, PBS and other polymer materials, while non-biodegradable traditional plastic bags are made of PE plastic.
2, different production standards
Biodegradable plastic bags need to comply with the standard GB21661-2008 and meet the environmental requirements, but the traditional non-biodegradable plastic bags do not need to follow such standards.
3, the decomposition time is not the same
Biodegradable bags are generally shared within a year, and some materials can even be decomposed within 72 days. While non-biodegradable plastic bags will take hundreds of years to degrade them, will produce a lot of pressure on the environment.
Ordinary plastic bags because in the ground does not decompose, crops, water, livestock and humans themselves are harmful, there will be white pollution and other phenomena, but biodegradable plastic bags buried inside the soil after, because the surrounding environment can meet the decomposition requirements, will be completely decomposed into carbon dioxide and water, belonging to the organic cycle, for the human body and the environment is not harmful.
