Thermoplastic polymer film composite linerless aluminum foil tape

Abstract

The invention provides a thermoplastic polymer film composite linerless aluminum foil tape. According to the thermoplastic polymer film composite linerless aluminum foil tape provided by the invention, lining paper is not used; and as the lining paper is thrown away as garbage during the using process, resources can be greatly saved, the production cost can be reduced, and the weight of a finished product aluminum foil layer tape is also greatly reduced. According to the thermoplastic polymer film composite linerless aluminum foil tape provided by the invention, a thermoplastic polymer film and one side of an aluminum foil layer are adhered and stuck together by heating through a heating roller so as to realize the release effect, and the manufacturing process is simple; furthermore, the finished product is high in tensile strength, easy to break and easy to uncoil and tear off from a tape coil, and can avoid the phenomenon that the tape is stretched; and the finished product is very convenient to operate by a machine or by hands.

Description

technical field [0001] The invention relates to an aluminum foil tape, in particular to an aluminum foil tape without backing paper and a manufacturing method thereof. Background technique [0002] At present, there are generally four types of aluminum foil tapes used for pipe insulation and for fixing condensation pipes in refrigerators, air conditioners, and freezers: [0003] 1. Aluminum foil tape with lining paper. The disadvantage of this kind of aluminum foil tape is that it needs to use lining paper. When using the lining paper, it needs to be torn off and discarded as garbage, which wastes resources, and the production cost is high, which is not environmentally friendly and causes waste; [0004] 2. Film-coated aluminum foil tape without backing paper. This product includes a plastic film layer, an intermediate adhesive layer, an aluminum foil layer and a primer layer. The intermediate adhesive layer needs to be glued by a rubber roller to connect the plastic film la...

Problems solved by technology

[0003] 1. Aluminum foil tape with lining paper. The disadvantage of this kind of aluminum foil tape is that it needs to use lining paper. When using the lining paper, it needs to be torn off and discarded as garbage, which wastes resources, and the production cost is high, which is not environmentally friendly and causes waste;

[0004] 2. Film-coated aluminum foil tape without backing paper. This product includes a plastic film layer, an intermediate adhesive layer, an aluminum foil layer and a primer layer. The intermediate adhesive layer needs to be glued by a rubber roller to connect the plastic film layer and the aluminum foil. layer, high production cost, complex production process, and the product is difficult to tear off and inconvenient to use;

[0005] 3. Aluminum foil tape without backing paper, which uses a layer of silicone oil as a release agent on the aluminum foil layer. The disadvantage is that the silicone oil causes organic solvent pollution, and the thickness of the aluminum foil layer is thick, which greatly wastes aluminum foil resources and the strength of the product is insufficient. , easy to pull off;

Since silicone oil is pre-coated on the film as a release agent, the entire production process is complicated and the cost is high
