Unidirectional air-permeable film suction bag is an assembly with exhaust function. The unidirectional air-permeable membrane can effectively suck the gas in the infusion system into the assembly and discharge it out of the infusion system; at the same time, it can prevent the resin from penetrating into the assembly. The top layer is a high-barrier vacuum bag film, which effectively prevents the gas sucked in from the unidirectional breathable film from leaking from the top layer. A diversion net is used in the middle to facilitate the air flow. This product is suitable for vacuum infusion molding process. It can draw out the air evenly and quickly and prevent the loss of resin. It is especially recommended to be used in the blade production process.
