Problems solved by technology

[0005] The object of the present invention is to provide a method for manufacturing an aluminum foil eight-side-sealed composite vacuum bag, by preparing aluminum foil rolls, PET polyester film rolls, and PET protective films respectively, and using a hot pressing roller to heat-coat the PET film on the aluminum foil roll, and Printing and aluminum washing hollow out the hot-coated PET film, and compound the PE protective film on the aluminum foil roll by preparing a water-soluble film adhesive, and then carry out slitting, rewinding and bag making, which solves the existing eight-sided problem. The protection, protection, and light-proof performance of the sealed packaging bag are poor, and the contents are easily affected by moisture.

Abstract

The invention discloses a method for producing an aluminum foil eight-edge-sealed compound vacuum bag and relates to the technical field of packaging bag preparation. The method for producing the aluminum foil eight-edge-sealed compound vacuum bag disclosed by the invention comprises the following steps: preparing an aluminum foil coil, preparing a PET polyester film reel, preparing a PE protective film, shunt winding, thermally covering a PET film, online printing, rewinding, washing aluminum and hollowing, compounding a PE protective film, drying and curing, performing compound qualificationdetection, slitting rewinding, and producing the bag. According to the method disclosed by the invention, by respectively preparing the aluminum foil coil, the PET polyester film reel and the PET protective film, the operation of thermally covering the PET film is performed on the aluminum foil coil by utilizing a hot pressing roller, and the thermally covered PET film is subjected to printing, aluminum washing and hollowing out. By preparing the water-soluble laminated adhesive, the PE protective film is compounded on the aluminum foil coil, and slitting rewinding and bag production can be performed, so that the protectiveness, protective property and shading property of the eight-edge-sealed packaging bag are improved, and the contents are not easy to be affected with damp.

Description

technical field [0001] The invention belongs to the technical field of packaging bag preparation, in particular to a method for manufacturing an aluminum foil eight-side-sealed composite vacuum bag. Background technique [0002] As we all know, the aluminum foil bag is a high-end packaging bag, and the printed aluminum foil bag is even more magnificent, which not only improves the grade of the goods packaged in the aluminum foil bag, but also improves the display value of the goods packaged in the aluminum foil bag. Package. [0003] Eight-side-seal packaging bags, also known as eight-side-seal zipper bags, eight-side-seal stand-up bags, and square-bottom bags, are the new favorites in the food packaging bag industry. [0004] The existing eight-side-seal packaging bag is mainly composed of two layers of film, including a printing layer and a heat-sealing layer, which have the advantages of good airtightness, but for products in the fields of high-end food, industry, electr...
