Problems solved by technology

In order to make full use of the aluminum-plastic film, it is hoped that the reserved heat-sealing edge should be as narrow as possible; at the same time, customers will also complain about the problem of insufficient heat-sealing strength during the use of aluminum-plastic film
The heat sealing strength is not enough, it is easy to cause safety problems such as liquid leakage, which poses a challenge to our current aluminum-plastic film products

Abstract

The invention provides an aluminum plastic film with low warping degree after deep punching and high heat sealing strength as well as a preparation method thereof. The aluminum plastic film is prepared by pressing a polyamide film layer, a first adhesion layer, an aluminum foil layer, a second adhesion layer and a polypropylene film layer into a whole body. According to the aluminum plastic film with low warping degree after deep punching, which is provided by the invention, the tensile strength of the polypropylene film is more than 40 MPa, the breaking elongation is more than 200 percent, and the stress generated by the polyamide film is counteracted by the stress generated by the high-strength casting polypropylene film layer in the deep punching process, so that the deep punching warping is avoided. The aluminum plastic film provided by the invention is simple in processing process, lightweight, high in deep punching depth, low in warping degree and high in heat sealing strength, and the product is safe and practical.

Description

technical field [0001] The invention relates to the field of lithium battery packaging materials, in particular to an aluminum-plastic film with low warpage and high heat-sealing strength after drawing and a preparation method thereof. Background technique [0002] At present, lithium-ion battery technology is becoming more and more mature, and it is widely used in 3C electronic products, power batteries, energy storage and other fields, which has a greater demand for lithium battery packaging materials. In the field of lithium battery packaging, there are currently three main packaging methods: cylindrical, square and soft. The soft bag is mainly made of aluminum-plastic film. Among the three methods, the market share of the aluminum-plastic film soft bag is increasing due to its advantages of light weight and safety. At present, the aluminum-plastic film used in lithium batteries is divided into dry method and thermal method. The structure of dry method is mostly PA / adhe...
