Embodiment 1

[0027] Such as figure 2 A kind of viscous load-carrying release film shown, comprises viscous base film 3, is located at viscous base film 3 and is the diaphragm 4 of 0.3mm in thickness, and offers the glue area hole 5 on septum 4; Wherein, viscous base film 3 includes a bottom film and a viscous silicone coating on the bottom film. The diaphragm 4 is set on the viscous layer of the viscous bottom film 3. The bottom film is a silica gel bottom film. The viscous coating is a viscous silica gel coating. A gap of 0.25mm is provided between the membrane, the glue area hole 5 and the glue material 1 .

[0028] Working principle: In this embodiment, the low-viscosity load-bearing release film is replaced by the original non-adhesive load-bearing release film to improve the adhesion between the load-bearing release film and the adhesive material 1, and the diaphragm 4 is attached to the sticky bottom during use. On the film 3, wherein, during the attaching process, the non-release ...

Embodiment 2

[0030] In this embodiment, the thickness of the diaphragm 4 is 0.2mm, and the gap between the glue area hole 5 and the rubber material 1 is 0.15mm, and the rest are the same as in the first embodiment.

Embodiment 3

[0032] In this embodiment, the thickness of the diaphragm 4 is 0.15mm, and the gap between the glue area hole 5 and the rubber material 1 is 0.20mm, and the rest are the same as in the embodiment 1.

Abstract

The invention relates to an adhesive bearing release film. The adhesive bearing release film comprises an adhesive bottom film, a diaphragm arranged on the adhesive bottom film and adhesive area holes formed in the diaphragm. During die cutting processing, an adhesive material is arranged in the adhesive area holes and is bonded with the adhesive bottom film. The low-viscosity bearing release film can replace an original non-viscosity bearing release film, so that the adhesion degree between the bearing release film and the adhesive material is improved, and the problem that the adhesive material and the bearing release film are easy to fall off due to infirm adhesion during production of the low-viscosity adhesive material can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of die-cutting, and relates to an adhesive bearing release film. Background technique [0002] In die-cutting production, glue is a commonly used raw material, and the processed products are various, and the types of glue are also various. The common ones are single-sided glue, double-sided glue and other glue materials. Different types of glue have different processing methods and degrees of difficulty, and different materials are selected for processing glue with different viscosities. In general, the higher the weight of the release film, the higher the degree of adhesion of the glue to it. Therefore, when the glue with high viscosity chooses to carry the release film, the weight of the release film will be appropriately reduced. Glue needs to increase the weight of the release film. [0003] Such as figure 1 As shown, in the existing process of making adhesive materials, a layer of release film 2 is u...
