Embodiment Construction

[0010] Referring to Fig. 1 and Fig. 2, the double-sided pressure-sensitive film without release film is mainly composed of a base material 1 and two self-adhesive adhesive layers 2, 3, and the two self-adhesive adhesive layers 2, 3 are respectively tightly The two self-adhesive adhesive layers 2, 3 on adjacent substrates 1 are directly rolled together on both sides of the substrate 1, and there is no release film or release paper between them. The crosslinking densities of the two self-adhesive adhesive layers 2 and 3 on both sides of the base material 1 are not equal, so as to increase the cohesive strength of the adhesive layer itself and prevent the two self-adhesive adhesive layers 2 and 3 from sticking together It is difficult to separate and destroy the adhesive layer structure; the two self-adhesive adhesive layers 2, 3 can also be manufactured using raw materials of different polarities or different systems (such as solution type, emulsion type, rubber type or polyacryl...

Abstract

The invention discloses no-separate-type membrane double-side pressure-sensitive film, which is characterized by mainly comprising a substrate and two self adhesive layers. The two self adhesive layers are respectively attached on the two sides of the substrate, and the two self adhesive layers of the adjacent substrates directly are winded together without containing separate-type paper or separate-type membrane; there is no separate-type paper or separate-type membrane between the two self adhesive layers, so that the separate-type material does not need to shuck off during usage, the usage is convenient, and a large amount of separate-type material garbages are reduced, which not only reduces the operation steps during usage, facilitates the use of the consumer, but also reduces the generation of a large amount of garbages, saves a great deal of natural resources for the society, and also has important meaning on the environmental protection.

Description

technical field [0001] The invention relates to a film, in particular to a double-sided pressure-sensitive film without release film. Background technique [0002] The general double-sided pressure-sensitive film generally used in the market is mostly four-layer structure, and it comprises base material, the self-adhesive adhesive layer that is adsorbed on both sides of base material and isolation layer, and isolation layer is release paper or release film. The separation layer is to prevent the adhesive tapes from sticking to each other when they are rolled into rolls, making it difficult to untie them for use. When it needs to be used, untie the tape, peel off the release paper or film, and expose the adhesive surfaces on both sides of the tape for pasting and fixing objects; at the same time, the peeled off paper or film has completed its mission and serves as a Waste thrown away. This not only causes inconvenience in use, but also causes a large amount of rubbish. Co...
