What is degradable plastic.

The definition of degradable plastics, adding a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biodegradants, etc.) of plastic.

For plastic products, various properties can meet the requirements of use, remain unchanged during the storage period, and can be degraded into environmentally friendly substances under natural environmental conditions after use. Therefore, it is also called environmentally friendly degradable plastic.

Tests have shown that most degradable plastics begin to become thinner, lose weight, and lose strength after being exposed to the general environment for 3 months, and gradually break into pieces. Ordinary degradable materials take hundreds of years to degrade.

The classification of degradable materials mainly includes these types

1. Photodegradable plastic

A photosensitizer is added to the plastic to gradually decompose the plastic under sunlight. It belongs to an earlier generation of degradable plastics, and its disadvantage is that the degradation time is difficult to predict due to sunlight and climate changes, so the degradation time cannot be controlled.

2. Folding biodegradable plastic

Under the action of microorganisms, plastics that can be completely decomposed into low-molecular compounds. It is characterized by convenient storage and transportation, as long as it is kept dry, it does not need to be protected from light, and has a wide range of applications. It can be used not only in agricultural mulch and packaging bags, but also in the field of medicine.

3. Photo/biodegradable plastic

A type of plastic that combines photodegradation and microorganisms. It has the characteristics of photodegradation and microbial degradation of plastics.

4. Water-degradable plastic

Water-absorbing substances are added to plastics, which can be dissolved in water after use. They are mainly used in medical and sanitary appliances (such as medical gloves) for easy destruction and disinfection.

Now our bottles and pump heads are gradually developing plastics with degradable materials. In order to protect the earth, we have developed PVC bottles in our bottles. He can play the function of protecting the environment and degrading. If you are interested in our biodegradable products, you can contact us directly, or send us an email. E-MAIL: sales@b-tech.cn
