Abstract

The invention provides a compression-resistant release film which comprises a base layer, a release agent coating is arranged on one side of the base layer, a second buffer layer is arranged on the other side of the base layer, a first buffer layer is arranged on the side, deviating from the base layer, of the second buffer layer, a first corrugated layer is arranged in the first buffer layer andis provided with a plurality of first corrugations which are uniformly distributed, a second corrugated layer is arranged in the second buffer layer and is provided with a plurality of second corrugations which are uniformly distributed, and the width of the first corrugations is not larger than that of the second corrugations. According to the release film, the first buffer layer is matched withthe second buffer layer, so that the release film has good buffer capacity, an impact force can be buffered, and good compression resistance is provided, under the action of external impact force, thefirst corrugations and the second corrugations in the first corrugated layer and the second corrugated layer can generate elastic deformation to convert the external force into elastic potential energy, so that the impact force is absorbed, and the compression resistance effect is improved.

Description

technical field [0001] The invention belongs to the technical field of release films, in particular to a pressure-resistant release film. Background technique [0002] Plastic base materials are widely used in the world because of their wide source of raw materials, low price and easy processing. At present, commonly used tough plastic substrates such as PC (polycarbonate), PCTG (polyester), PVC (polyvinyl chloride) and other molded products have problems such as low hardness, poor wear resistance, and easy scratches, while commonly used brittle Substrates such as PMMA (organic glass), TAC (cellulose acetate) and other products have high hardness and have a certain wear-resistant and anti-scratch effect, but there are problems such as easy fracture due to impact. [0003] The release film refers to a film whose surface can be distinguished. The release film is not sticky or slightly sticky after contacting with a specific material under limited conditions. [0004] In the ...
