PLA monofilament is a continuous filament made of polylactic acid (PLA). Its raw material comes from lactic acid produced during the fermentation of crops such as corn, cassava, and wheat, making it a truly bio-based and environmentally friendly material.
With increasingly stringent environmental regulations and global brands accelerating the use of green alternative materials, PLA monofilament, with its advantages of being biodegradable, compostable, and sourced from renewable resources, is becoming a key material in industries such as textiles, food packaging, and medical supplies.
Monofee, as a professional monofilament yarn manufacturer, provides PLA monofilament in various specifications. Currently, the 30D specification is widely used in tea bags, and customized versions can also be flexibly customized according to customer needs.
PLA Monofilament Material Analysis
-
Diameter Range: 0.05–1.0 mm
-
Melting Point: 200–235℃
-
Strength: ≥3.0 cN/dtex
-
Appearance: Good gloss, high transparency
-
Touch: Soft and smooth, excellent hand feel
-
Other Properties: Good heat resistance, moderate water absorption, natural antibacterial properties, flame retardancy
After use, PLA monofilament decomposes into water and carbon dioxide in industrial composting environments, completely entering the natural carbon cycle without causing secondary pollution.
Compared to traditional PP, PET, and other difficult-to-degrade materials, PLA monofilament is an indispensable alternative in the future sustainable industrial chain.
