Production process: hot fusion welding

PP:polypropylene needle felt
PE:Polyester Needled Felt

Product Description:
Full hot melt filter bag adopts three-dimensional three-dimensional deep structure and heat-soluble seamless combination technology to ensure filtration efficiency and no leakage: suitable for low and medium viscosity liquid filtration environment, with stable higher filtration flow rate, can effectively intercept a variety of soft and hard impurities.

Product Features

-Different sealing ring mouths are available, suitable for various filters
-All hot melt process to ensure no side leakage
-The material does not contain silicone and other additives to avoid chemical leaching
-Special heat treatment process on the surface of the filter material to eliminate fiber shedding
-Food grade filtration requirements can be met
