Abstract
A novel high-transparency package film for indicator-type preservatives belongs to the technical field of package films. A plastic film layer is arranged at the outer layer of the package film; a heat sealing breathable film layer is arranged at the inner layer of the package film; a non-porous breathable layer is arranged between the plastic film layer and the heat sealing breathable film layer; the non-porous breathable layer is glued and compounded with the plastic film layer through a first bonding layer; and the non-porous breathable layer is glued and compounded with the heat sealing breathable film layer through a second bonding layer. The novel high-transparency package film for the indicator-type preservatives is simple in structure and reasonable in design; an indicator package area and an oxygen absorbent package area of the package film is not required to be distinguished anymore; the processing technique is simple; the rate of finished products is high; and the non-porous breathable layer is high in transparency and free from the hidden danger of powder leakage.
