RAW MATERIAL
PLA
Item No: YPRX-PLA01
Molecular Formula: H-[OCHCH3CO]n-OH
CAS NO: 26100-51-6
Color: White
Standard: GB/T 29284-2012
PLA can be made into film products with high transparency, good barrier properties, excellent processability and mechanical properities,and can be used for flexible packaging of fruits and vegetables.
PLA can form a weekly acidic environment on the surface of the product. It has a basis for antibacterial and antifungal. If other antibacterial agents are used in addition, it can achieve an antibacterial rate of more than 90%, and can be used for antibacterial packaging of products.
PBS
Item No: YPRX-PBS01, YPRX-PBS02
Molecular Formula: HO-(CO-(CH2)4-CO-O-(CH2)4-0)n-H
CAS NO: 25777-14-4
Standard: GB/T 30294-2013
Color: Natural white
Application: injection molding tablewares and cutlery textile, fishing net, engineering components medical applications, etc.
PBS is widely used in packaging (including food packaging, cosmetic bottles, drug bottles), tableware, disposable medical supplies, agricultural film, pesticide and fertilizer slow-release materials, biomedical polymer materials and other fields.
It can not only meet the demand through petrochemical products, but also produce natural renewable crop products such as cellulose, diary by-products, glucose, fructose and lactose through biological fermentation, so as to realize green circular production from nature and return to nature.
PBAT
Item No: YPRX-PBAT01
Molecular Formula: H-(O-(CH2)4-O-CO-(CH2)4-CO-)n-(O-(CH2)4-O-CO-C6H4-CO-)m-H)
CAS NO: 55231-08-8
Color: Natural white
Standard: GB/T 32336-2015
PBAT (short for polybutylene adipate terephthalate) is a biodegradable random copolyme, specifically a copolyester of adipic acid, 1,4-butanediol and terephthalic acid(from dimethyl terephthalate).
PBAT is generally seen as a fully biodegradable alternative to low-density polyrthylene, having many similar properties including flexibility and resilience, which makes it ideal for blending with another biodegradable polymer, allowing it to be used for many similar uses such as plastic bags and wraps.
How do biodegradable bags degrade?
Degradable bag refers to a plastic bag that can be degraded under specific conditions, usually made of biodegradable materials such as polylactic acid (PLA) and polyester (PBAT).
The process of degradation is carried out through microbial action, hydrolysis, oxidation and other ways to decompose polymer molecules into small molecular substances, and eventually form natural substances such as carbon dioxide, water and organic matter, without causing pollution to the environment. Compared with ordinary plastic bags, degradable bags have the advantages of environmental protection and sustainability.

DAGRADATION PROCESS
Biodegradable bags refer to plastic bags that can be completely degraded under specific conditions. They are usually made of biodegradable materials such as polylactic acid (PLA) and polyester (PBAT), which reduce their stability during production and make them easier to degrade in the natural environment without residues.
Compared with ordinary plastic bags, biodegradable bags have the advantages of environmental protection and sustainability. The degradation process refers to the decomposition of polymer molecules into small molecules through microbial action, hydrolysis, oxidation, and other methods, ultimately forming natural substances such as carbon dioxide, water, and organic matter. The degradation products are carbon dioxide and water, which can be directly absorbed by plants in the soil, returned to the soil, or entered the general environment, and can be degraded without polluting the environment.
