Polylactic acid (PLA) fiber has gained popularity as a filling material, particularly in hollow fillings, due to its unique combination of environmental and functional benefits.
PLA Fiber Filling
hollow fiber filling
Product Description
Polylactic acid (PLA) fiber is a biodegradable and eco-friendly material made from renewable resources like cornstarch or sugarcane,It is also known as corn fiber.
When used as a hollow filling material, PLA fibers offer additional benefits. The hollow structure enhances thermal insulation and lightweight properties, making it ideal for applications like bedding, jackets, and outdoor gear. The air trapped within the hollow structure helps retain warmth while keeping the material light and breathable.
PLA fibers also exhibit excellent moisture-wicking and hypoallergenic properties, ensuring comfort and safety for sensitive users. Additionally, they provide good resilience and softness, maintaining their shape and comfort over time.
PLA fibers, especially when used in hollow fillings, provide a sustainable, lightweight, and highly functional solution for various industries, all while supporting environmental responsibility.

Home Textiles
Examples: Pillows, cushions, comforters, mattresses.
- Softness and Loft: PLA fiber provides a plush and luxurious feel, ideal for creating soft yet supportive bedding products. Its hollow structure ensures the material maintains its loft, giving pillows and cushions a fluffy and voluminous appearance.
