With the development of modern biotechnology, more and more attention has been paid to biodegradable plastics, which has become a new generation of research and development hotspot.
A. According to the principle of degradable mechanism
1. Photodegradable plastics：
A photosensitizer is added to the plastic to gradually decompose it in sunlight.
2. Biodegradable plastics：
Plastics that decompose completely into low molecular compounds under the action of microorganisms.
3. Light/biodegradable plastic bags：
A type of plastic that combines photodegradation and microbiota, having the characteristics of both photodegradation and microbiota degradation in order to achieve complete degradation.
4. Water-degradable plastic：
Add water-absorbing substances to plastics, which can be dissolved in water after use.
GTMSMART Pla Biodegradable Thermoforming Machines are in the category of biodegradable.
B. According to raw materials
Degradable materials extracted from biomass resources (such as plant fibers, starch, etc.).
1. Petrochemical based plastics(such as petroleum and natural gas.)
2. Bio-based plastics(such as plant fibers, starch, etc.).
GTMSMART Biodegradable Food Container Making Machines are in the category of bio-based plastics.
C. According to the degradation effect
1. Total degradation
2. Partial degradation
GTMSMART PLA Degradable Plastic Thermoforming Machines are in the category of Total degradation.
D.According to the use of classification
1. Environmental (natural) degradable plastics:
Namely new plastics, photodegradable plastics, biodegradable plastics, photooxide/biocomprehensive degradable plastics, thermoplastic starch resin degradable plastics, Co2-based biodegradable plastic
2. Biodegradable (environmental) plastics:
Used in medicine for surgical sutures, artificial bones, etc.
GTMSMART PLA Thermoforming Machines are in the category of Environmental (natural) degradable plastics.
