Description

Technical Field

[0001] The utility model relates to the technical field of adhesive films, in particular to a tread pattern type packaging adhesive film. Background Art

[0002] The advantages of photovoltaic encapsulation film in terms of adhesion, durability, optical properties, etc. make it more and more widely used in current components and various optical products. The film is processed into a finished product after a series of operations. Existing films often have problems such as low strength and easy slippage on the surface, which affects normal use. Summary of the invention

[0003] In order to solve the above technical problems, the utility model provides a tread-type packaging adhesive film, which can ensure the strength of the adhesive film and prevent the surface from slipping.

[0004] The technical solution is as follows: a tread-type packaging film, characterized in that it includes a film body, the film body includes an upper POE particle layer, a middle mixed particle layer and a lower POE particle layer, the film body is provided with tread protrusions arranged side by side at intervals, the tread protrusions include long strip protrusions and inclined short protrusions arranged on both sides of the long strip protrusions.

[0005] It is further characterized in that the intermediate mixed particle layer is a mixed layer of POE particles and EVA particles;

[0006] The directions of the inclined short protrusions on both sides of two adjacent long protrusions are opposite.

[0007] By adopting the utility model, the three-layer rubber film effectively improves the overall strength of the rubber film, and the tread protrusions are added on the surface, and the friction force when the rubber film contacts is improved by using the concave and convex surface, thereby effectively preventing the rubber film from slipping.

[0011] See Figures 1 to 3As shown, a tread type packaging film includes a film body 1, the film body 1 includes an upper POE particle layer 1-1, an intermediate mixed particle layer 1-2 and a lower POE particle layer 1-3, wherein the intermediate mixed particle layer 1-2 is a mixed layer of POE particles and EVA particles, POE is composed of octene and polyolefin resin, and a continuous phase and a dispersed phase are a two-phase separated polymer blend, POE is characterized by excellent toughness and good processability, there is no unsaturated bond in the POE molecular structure, and it has excellent aging resistance; POE has a narrow molecular weight distribution, good fluidity, and good compatibility with polyolefins; after EVA is added to POE, the resilience and toughness will be increased, and the wear resistance will also be improved.

[0012] The rubber film body 1 is provided with tread protrusions 2 arranged side by side and at intervals. The tread protrusions 2 include long protrusions 2-1 and inclined short protrusions 2-2 arranged on both sides of the long protrusions 2-1. The inclined short protrusions 2-2 on both sides of two adjacent long protrusions 2-1 are in opposite directions. The surface of the rubber film is uneven. When the rubber film contacts other objects, the presence of the tread protrusions 2 can effectively increase the friction of the surface, and it is not easy to slip.
