Laminated film with multi-layer sealing film

Abstract

The invention belongs to the technical field of laminated films, and particularly relates to a laminated film with a multi-layer sealing film. The laminated film comprises a film main body and a positioning block, wherein the film main body comprises an inner layer, an outer layer and a middle layer; the middle layer is positioned between the inner layer and the outer layer; semicircular grooves which are uniformly arranged are formed in the surface of one side of the middle layer; through holes which are uniformly arranged are formed in the surface of the middle layer below the groove; tearing lines which are uniformly arranged are arranged in the middle layer; and the upper surface of the middle layer is fixedly adhered with easy-to-tear films which are uniformly arranged. According to the laminated film, the film body can be conveniently torn, the end part of the film body can be conveniently positioned by a user after the film body is torn, the user can conveniently find the end part of the film body when the film body is used again, and meanwhile, the film body is convenient and rapid in the tearing process.

Description

technical field [0001] The invention belongs to the technical field of laminated films, in particular to a laminated film with multi-layer sealing films. Background technique [0002] Lamination molding method refers to the method of combining two or more layers of the same or different materials into a whole by heating and pressure, and the film is a thin and soft transparent sheet, which is made of plastic, adhesive, rubber or other materials. Manufactured, the scientific explanation of thin film is: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of the substrate. At the same time, during the lamination operation, the edge can be laminated so that the finished product has multiple Layer sealing film, and this is the prior art. [0003] However, there are still some deficiencies in the existing laminated film in use: when the existing laminated film is used, the general laminated film is rolled up by winding, and it is not convenien...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies in the prior art and solve the problem that the user cannot find the port in time when the laminated film is in use, the method of tearing by hand or scissors is too wasteful of manpower and material resources, and the tearing process is too time-consuming. Setting breakpoints on the surface of the laminated film cannot guarantee the overall strength and sealing effect of the laminated film, which can easily cause water leakage at the breakpoints, and even if the breakpoints are set to be torn by hand, it is still very easy to cause uneven tearing, resulting in The problem of waste of laminated film, a laminated film with multi-layer sealing film proposed by the present invention
