Abstract

The invention belongs to the technical field of protective films, and particularly relates to a PET silica gel protective film, which comprises a film body, a silica gel layer arranged at the top end of the film body, sealing pieces arranged on the two sides of the film body, a refrigerating layer arranged at the bottom end of the film body, a deoxygenization layer arranged between the refrigerating layer and the silica gel layer, a deoxygenization working layer arranged in the deoxygenization layer, a deoxidizing interlayer is arranged between the deoxidizing working layers in the deoxidizing layer, an iron layer is arranged at the top end in the deoxidizing working layer, a carbon layer is arranged at the bottom end in the deoxidizing working layer, deoxidizing holes are formed in the two side walls of the deoxidizing working layer in a penetrating mode, a refrigerating working layer is arranged in the refrigerating layer, and refrigerating holes are formed in the two side walls of the refrigerating working layer in a penetrating mode; and a refrigerating interlayer is arranged between the refrigerating working layers in the refrigerating layer. By arranging a sealing sheet, the deoxidizing layer and the refrigerating layer, an oxygen-free environment can be provided for an object packaged and protected by the protective film, and a low-temperature environment can be provided for the object packaged and protected by the protective film for a long time.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a PET silica gel protective film. Background technique [0002] PET silicone protective film is made of plastic film or aluminum-plastic composite material, etc., coated with low-viscosity pressure-sensitive adhesive on one side, and then cut into rolls. Attached to the surface of the profile, it can effectively prevent the surface of the profile from being scratched or polluted during extrusion molding, transportation, window forming, and installation. Its appearance has brought great convenience to profile production, door and window assembly and construction units, but there are the following problems: [0003] 1. When the protective film acts on objects, it can form a well-closed, dustproof and waterproof space. The transportation and storage of the acting objects often requires a low-temperature environment, and the protective film does not have the function of pro...
