The Difference Between Degradable And Non-degradable Plastics

The recent hot ban on plastic is related to the voice of the people, but it is also an urgent measure, because non-degradable raw materials are great harm to the human body and the natural environment.

How much do you know about the difference between degradable and non-degradable plastics?
First, let's talk about the meaning of non-degradable plastic: the key raw materials of non-degradable plastic bags are polyethylene and polyvinyl chloride, which are often used to install other objects and are indispensable to everyone's daily life. Due to its advantages of cheap, ultra-light net weight, large volume and easy storage and arrangement, the degradation cycle time of the packaging bag is very long, because of the uniqueness of the material, it must be about two hundred years to degrade, or most of the non-degradable, even if degraded, it will lead to caking damage to the soil layer and other conditions.

1, the material is not the same degradable plastic bags (that is, environmentally friendly plastic bags) the application material is PLA, PHAs, PBA, PBS and other fiber materials, and non-degradable traditional packaging bags are PE plastic materials.

2, product standards are not the same as degradable plastic bags must meet the national industry standard GB/T21661-2008, has achieved environmental protection level. Traditional non-degradable plastic bags do not need to comply with this specification.

3, the dissolution time is not the same degradable plastic bags can generally be dissolved within a year, and the Olympic green plastic bags can even be gradually dissolved 72 days after abandonment. The non-degradable packaging bag must take 200 years to degrade it.

Nanjing COLOWE Chemical Machinery Co., Ltd. is a specialized in the manufacture of the same direction screw mixing unit based plastic polymer mixing modification equipment company sincerely hope that we try to avoid the use of non-degradable plastic bags!
