Production method of high-strength aluminum-plastic film

Abstract

The invention relates to a production method of a high-strength aluminum plastic film. Production equipment adopted by the production method comprises a bottom plate, a [-shaped frame body, a leveling device, a hot blowing device and an extrusion device, the [-shaped frame body is fixedly mounted on the upper end surface of the bottom plate, the leveling device is arranged on the left side in the [-shaped frame body, and the hot blowing device is mounted on the right side of the leveling device; and the extrusion device is arranged on the right side wall in the [-shaped frame body. The production method can solve the following possible problems in the existing aluminum plastic film manufacturing process: a, the cost is high, the flattening efficiency is low, and the production efficiency of an aluminum plastic film is greatly reduced because the upper end surfaces of a plastic film and an aluminum foil layer are manually extruded and flattened by a large amount of manpower; and b, in the conveying process of the plastic film and the aluminum foil layer, the plastic film and the aluminum foil layer are frequently wrinkled and damaged, so that the produced plastic film and the aluminum foil layer are not completely attracted, the quality of the produced aluminum plastic film is poor, and the using effect is reduced.

Description

technical field [0001] The invention relates to the field of aluminum-plastic film production, in particular to a production method of high-strength aluminum-plastic film. Background technique [0002] Aluminum-plastic film refers to a composite film that is compounded with an aluminum foil layer on the surface of the plastic film to make it have high strength and better protective performance. It is a very popular packaging material. During manufacture, the plastic film is usually transported flat first, and then the upper end of the plastic film is laminated with an aluminum foil layer, thereby producing a high-strength, durable aluminum-plastic film. [0003] At present, the existing aluminum-plastic film may encounter the following problems in the manufacturing process: a. The upper end surface of the plastic film and the aluminum foil layer is squeezed and leveled manually, which requires more manpower, resulting in higher cost and smooth The efficiency is low, which g...

Problems solved by technology

[0005] The present invention can solve the following problems that the existing aluminum-plastic film may encounter in the manufacturing process: a. The upper end faces of the plastic film and the aluminum foil layer are squeezed and leveled manually, which requires more manpower, resulting in higher cost, And the leveling efficiency is low, which greatly reduces the production efficiency of aluminum-plastic film; b. In the process of conveying the plastic film and aluminum foil layer, there are often wrinkles and breakages, resulting in incomplete absorption of the manufactured plastic film and aluminum foil layer. As a result, the quality of the produced aluminum-plastic film is poor, thereby reducing its use effect
