Microporous induction sealing is a novel packaging sealing technology. A microporous structure integrates on the basis of traditional induction sealing, so that the packaging not only can ensure the tightness of products, but also can meet a certain degree of air permeability needs and reaches better preservation effect. There Microporous induction sealing is created by punching small pores in the induction sealing film. These micropores are typically tens of micron and hundreds of microns in diameter, which is not easy to see directly by the eye. Once packaged, microporous membrane can be semipermeable to gases like O2 and CO2 whilst blocking moisture and dust.
