A laminated film with a multi-layer sealing film

Abstract

The invention belongs to the technical field of laminated films, in particular to a laminated film with a multi-layer sealing film, comprising a film main body and a positioning block, the film main body comprising an inner layer, an outer layer and an intermediate layer; the intermediate layer Located between the inner layer and the outer layer; one side surface of the middle layer is provided with evenly arranged semicircular designed grooves; the surface of the middle layer is provided with evenly arranged through holes under the groove; the middle layer There are evenly arranged tearing lines inside; the upper surface of the middle layer is fixed and adhered with an evenly arranged easy-to-tear film; the present invention is convenient for tearing the film body, and it is convenient for the user to locate the end of the film body after tearing. It is convenient for users to find when they use it again, and at the same time, the film body is convenient and quick during 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
