The principle of PE Breathable Film

The principle of breathable film is very simple: INORGANIC + stretching micropores, in fact, the operation is very exquisite, only the right size, well-distributed micropores to be effective.

When the water vapor concentration on one side of the film is higher than that on the other side, a humidity gradient pressure difference is formed. This provides the basic conditions for gas (Vapor) convection, which tends to balance the relative humidity on both sides of the film.

The permeability film is used as a water-resisting film, which has a blocking effect on the liquid. Because of the many channels in the film, the ratio of length to diameter of the Zigzag Channel is very large, which can be understood as capillary. Therefore, in the same liquid (such as water) , the same pressure, as long as the capillary column height is less than the length of the capillary, you can ensure that the liquid will not leak.

Therefore, the water barrier of the film directly depends on the size of the pores and the length of the passage. This property can usually be measured by the water resistance pressure (ΔP) . When the water pressure exceeds the water resistance pressure value of the microporous membrane, the water will leak out.
