Breathable induction foil is an induction sealing foil with a breathability function, just as the name suggests. Combining the performance of induction seal and breathable film, it can selectively allow gas to enter and exit from package, making it possible to maintain the freshness of product for a long time, extend shelf life and improving quality of product according to product requirements. Breathable induction foil works on the same principle as that of common induction foil. They both melt the hot melt adhesive via high-frequency magnetic field induction heating to create a seal. The difference is that breathability has been added to induction foil with the help of micropores or microchannels in the material. These minute pores or channels are the kinds of films that can enter and exit the gas molecules in a limited range freely, effectively controlling the gas composition within packaging.
