Plastic waste has always been one of the biggest challenges that troubles today's society. Generally, plastic waste cannot degrade itself in the natural environment, and it has a significant impact on the environment and ecology. In order to solve the problems caused by plastic waste in our daily lives, biodegradable plastics have been applied. The biodegradable plastics currently used in China mainly include the following materials:
Polylactic acid (PLA): PLA is a biodegradable plastic prepared from plant materials such as corn and sugarcane. It has good transparency, processability, and degradability, and can be used in fields such as food packaging, medical devices, and agricultural films.
Polyhydroxy fatty acid esters (PHA): PHA is a type of biodegradable plastic synthesized by microbial fermentation, which has good biodegradability, biocompatibility, and processability. It can be applied in fields such as packaging materials, medical supplies, and agricultural films.
Polybutylene succinate (PBAT): PBAT is a kind of degradable plastic synthesized from butylene glycol, succinic acid and other raw materials. It has good degradability, flexibility and processability, and can be used in Bin bag, packaging film and other fields.
Polycaprolactone (PCL): PCL is a biodegradable plastic synthesized from caprolactone, which has good degradability, plasticity and biocompatibility. It can be applied in the medical field, 3D printing materials, packaging materials, etc.
Starch based degradable plastics: Starch based degradable plastics are degradable plastics prepared from starch as the main raw material, with good degradability and processability. It can be used in food packaging, agricultural film, Disposable tableware and other fields.
There are some differences in the performance of degradable plastics made of different materials, such as degradability rate, mechanical properties, thermal stability, etc. In terms of specific applications, each material of biodegradable plastic has the following characteristics:
PLA: With high transparency, it can be used for food packaging, medical devices, agricultural films, etc.
PHA: It has good biocompatibility and can be used for medical supplies, packaging materials, etc.
PBAT: It has good flexibility and can be used for Bin bag, packaging films, etc.
PCL: With a long degradation cycle, it can be used in the medical field, 3D printing materials, etc.
Starch based degradable plastic: It has good degradability and can be used for food packaging, agricultural film, Disposable tableware, etc.
Suitable biodegradable plastic materials need to be selected based on specific application scenarios and requirements. At the same time, different biodegradable plastic materials can also be mixed for better performance and degradation characteristics.
