Non-Woven PLA Fabric - Factory Compostable Tea Filter Roll
Compostable PLA non-woven filter fabric for ultrasonic triangle tea bag machines. Two GSM options, multiple roll widths, DIN EN 13432 certified. We process and supply from our Hangzhou workshop.
Product Details
Choosing a filter material for your tea bag line involves more than checking a spec sheet. You need to know how the material behaves on your machine, how it handles during storage, and whether your end customers will accept the compostability claims on your packaging.
We supply PLA non-woven fabric in two weights for ultrasonic triangle tea bag machines. The material is made from polylactic acid, a biopolymer produced from renewable plant starches through fermentation and polymerization. We do not produce the raw resin or spin the fibers ourselves; that is done by specialized biopolymer manufacturers. What we do in our Hangzhou workshop is take the finished PLA non-woven fabric, slit it to the widths you need, inspect every roll for consistency, and package it so it reaches your production line ready to run.
The two weights we stock are 21 GSM and 25 GSM. Both work on ultrasonic sealing equipment. The 21 GSM gives you a lighter, faster-flowing filter suited to finer cut teas. The 25 GSM is slightly denser, which helps if you are packing herbal blends with larger leaf pieces or if you want a little more body in the cup. Widths run from 120mm to 180mm as standard, and we can slit custom widths if your machine calls for something specific.

Processed in Our Hangzhou Workshop
We source finished PLA non-woven fabric and process it in our workshop - slitting to width, inspecting each roll, and packaging for direct use on your ultrasonic tea bag machine.
Same Widths as Nylon and PET
Switch between materials without changing your forming station or packaging artwork. Simplifies inventory and reduces retooling downtime.
Two GSM Options
21 GSM for lighter, faster extraction with finer teas. 25 GSM for denser filtration and herbal blends. Both ultrasonic-compatible and available in 120-180mm widths.
DIN EN 13432 Certified
Meets compostable packaging standards. Decomposes into CO2 and water under industrial composting conditions within 90-180 days. SGS documentation available on request.

Applications
Ideal Uses for Our PLA Tea Bag Material
Triangle Tea Bags
Primary format for ultrasonic machines. Pyramid shape allows good water circulation; PLA non-woven holds its shape during the 2-5 minute brew.
Herbal Infusions
25 GSM suits chamomile, peppermint, rooibos with larger particles. Health-conscious consumers respond well to plant-based filter claims.
Cold Brew Tea
Durable in refrigerated water over 8-12 hours. 25 GSM recommended for longer contact times without over-extraction.
Dual Product Lines
Run compostable and standard lines on the same machine. Same roll widths mean no retooling between production runs.
