Abstract
The invention discloses an anti-fogging membrane, relating to the field of packaging materials. The anti-fogging membrane comprises a light-resisting layer, an anti-fogging layer, a core layer and a protective layer, wherein the anti-fogging layer is arranged above the core layer and the light-resisting layer is made of a composite material of PBT and PC; the light-resisting layer is arranged above the anti-fogging layer; the anti-fogging layer is made of a composite material of BMA and EA materials; the protective layer is arranged under the core layer and the core layer is made of a PA material; and the protective layer is made of an HDPE material. The anti-fogging membrane has an excellent anti-fogging performance and good glossiness, and also has good acid and alkali resistance, corrosion resistance and ageing resistance, so that the anti-fogging membrane is a nontoxic environment-friendly membrane suitable for packaging fresh fruits, vegetables and the like.
Description
Technical field
The present invention relates to packaging material field, particularly relate to a kind of food packaging antifog film.
Background technology
Antifog film is that a kind of steam that prevents forms knot mist at film surface and affects the functional film of transparency.Such as bag, glue-free composite membrane etc. still keep the build-in attribute of BOPP film, such as keep the high grade of transparency, there is splendid added property and illustrative, and keep very high intensity, do not affect transport, store and use, if Chinese application number is that CN 203267424 U discloses a kind of antifog film, comprise pet base material, anti-fog layer is provided with above described pet base material, diaphragm is provided with above this anti-fog layer, the below of described pet base material is bonding with release liners by adhesive-layer simultaneously, the antifog film Main Auto vehicle window of this technology, rearview mirror, high-grade hotel glass and Domestic glass first-class, the reflect heat of most of solar energy can be gone back in the summer of sweltering heat, play and keep indoor temperature can not raise too much, reduce room conditioning load, thus reach energy-conservation object, in addition, its one side of the antifog film set forth is tough and tensile PET base material, one side is adhesive-layer, the one side that this adhesive-layer and eyeglass are painted has good bonding force, if eyeglass has been staved because of carelessness, fragment firmly can not will be fallen down by gluing, can prevent the glass be scattered from may cause damage to people and other article like this, but the antifog film of this technology does not have good glossiness, not there is better acid and alkali-resistance simultaneously yet, anticorrosive, resistance to ag(e)ing, be unwell to packaging fresh fruit, the food such as vegetables.
