Problems solved by technology

However, there is no functional film specially used for polarizers, which is prone to inconsistent angles with the polarizing coating of polarizers, resulting in halos caused by inconsistent light wavelength bands, and the release effect is poor, which is not convenient for lamination. After the adhesive surface is peeled off

Abstract

The invention discloses a special stripping functional film for a polaroid. The film comprises an alignment-angle coating, a PET polyester film and a release coating, wherein the alignment-angle coating, the PET polyester film and the release coating are laminated sequentially from top to bottom. According to the special stripping functional film for the polaroid, the structural design is reasonable, the PET polyester film is ingeniously coated with the alignment-angle coating and the release coating, and the ingredient proportioning ratio of the alignment-angle coating and the release coating is reasonably optimized, so that the film has a certain alignment angle which is consistent with an angle of a polarization coating of the polaroid, a halo phenomenon caused by inconsistency of wavebands of light is effectively reduced, the display quality is improved, and better use comfort is brought for people; and meanwhile, the film has a release function, so that the aim that the stripping is facilitated after the film is stuck to a glue face is achieved, the product quality is effectively guaranteed, the comprehensive competitiveness of products is improved, and thus the extensive popularization and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of polarizers, in particular to a special peelable functional film for polarizers. Background technique [0002] Polarizers are widely used in flat panel displays to improve display quality. With the rapid development of the domestic liquid crystal industry, the polarizer industry on domestic liquid crystals has also developed rapidly. In order to reduce the manufacturing cost of polarizers and break the supply bottleneck of functional films such as protective films and release films monopolized by Japanese companies, There is an urgent demand for domestic production of functional films dedicated to polarizers to replace Japanese and Korean products, prompting domestic functional film manufacturers to invest heavily in research and development. The release film refers to a film with a separable surface. The release film is not sticky or slightly sticky after being in contact with a specific material under l...
