Product Description

Xiong County Xiashi Packing Co., Ltd. is the Chinese factory of Jinbo Breathing Paper. Breathable vapour barrier membrane is a functional film used in building enclosure structures. Using our products is not only moisture-proof and mold-proof, but also can improve the service life of the building.

What is a breathable vapour barrier membrane?

Breathable vapour barrier membrane is a kind of polymer functional film, which is mainly characterized by blocking the penetration of liquid water and air, but allowing water vapor to pass through. The main materials are PP and PE. The main function is waterproof and breathable: let the water vapor be discharged and prevent water and moisture from coming in from the outside.
