PLA Application

Polylactic Acid (PLA) Applications

Centered on bio-based, biodegradable PLA, we provide safe and eco-friendly new material solutions for food contact, textile fibers, 3D printing and more.

Health & Environmental Challenges

Global plastic bottle sales reach 1 million per minute, over 480 billion annually, mostly PET. After 10 months or under high temperature, PET can release carcinogen DEHP and is non-degradable, polluting land and oceans.
China's food delivery industry exceeds 20 million daily orders; disposable meal boxes are mainly PP and hard to degrade.
Baby bottles and essentials often use PC, which may release BPA and other toxins affecting child development.
PLA is plant-based with lactic acid monomer (a common food additive), making it an ideal alternative to PET, PP and PC.

Plastic waste and environmental challenges

What is PLA?

Polylactic acid (PLA) is a polymer made from biomass such as corn, cassava and sweet potato through fermentation to lactic acid and then polymerization. It has the basic characteristics of general polymers and is suitable for injection molding, thermoforming, blow molding, foaming, spinning and other processes.

Applications — Packaging & Food Containers

Food Contact

Safe and eco-friendly — ideal replacement for PET / PP / PC

Advantages of PLA

Safety: Raw materials from plants; lactic acid monomer is a common food additive and a major component of yogurt.
Eco-friendly: Biodegrades to CO₂ and water after use; petroleum plastics take centuries. PLA has lower lifecycle carbon — about two-thirds less than PET.
Our PLA grades S160, R160, SC160 are suitable for food contact materials. See product datasheets for specifications.

Applications — Packaging

Applications — Disposable Tableware

Textile Materials

Bio-based biodegradable fibers — a new era of green textiles

Advantages of PLA Fiber

PLA fiber is made from PLA by melt spinning and other processes — a fully biodegradable bio-based fiber.
Eco-friendly: Bio-based, fully biodegradable (under composting), low-carbon production.
Antibacterial & skin-friendly: Antibacterial rate >98%; weakly acidic surface is skin-friendly.
Moisture & breathability: Better than polyester; blends with cotton, viscose, Tencel, Modal, wool, etc.
Spinning grades S120, SC160 etc.; stereocomplex PLA offers excellent heat resistance with melting point above 210℃.

PLA Fiber Applications

Hygiene & medical: Sanitary pads, diapers, masks, surgical gowns, sutures, gauze, bandages, etc.
Apparel: Underwear, sportswear, baby clothing, socks, ties, etc.
Daily goods: Tea bags, wipes, towels, bedding, pillows, curtains, plush toys, filter bags, etc.
Outdoor: Seedling non-woven fabric, frost and weed control cloth, etc.

3D Printing

Eco-friendly additive manufacturing material — safe, low odor, easy to form

Eco-friendly 3D Printing Material — PLA

3D printing is a hallmark of the third industrial revolution. FDM is widely used for fixtures, teaching models, toys, design prototypes and surgical planning models.
PLA is a key printing polymer from biomass fermentation, low-carbon lifecycle, about two-thirds less carbon than PET.
Lactic acid monomer is a common food additive; degrades to CO₂ and water after use.

Usage Advantages

Good adhesion to print bed, no heated bed required
Better dimensional stability than ABS, less warping
Compatible with various 3D printer models
No pungent odor — suitable for desktop office use
Good surface gloss, fast melting speed
