Preparation method and structure of aluminum foil material specially used for packaging hair dyes

Abstract

The invention discloses a preparation method and a structure of an aluminum foil material specially used for packaging hair dyes. The structure sequentially comprises a polyester film A, an aluminum foil, a polyester film B and a polypropylene film from top to bottom, sectional bonding work is adopted to make the aluminum foil be bonded the lower layer of the polyester film A, to make the other layer of the aluminum foil be bonded to the polyester film B and to make the polypropylene film be bonded to the other layer of the polyester film B, all layers are bonded through matching an adhesive with pressing and heating of a hot press, standing is carried out at a certain temperature to realize drying and solidification, and a whole body obtained after sectional completion of adhesion of all layer materials is instantly heated to a predetermined temperature to realize outside-to-inside compounding molding in order to prepare the aluminum foil material specially used for packaging hair dyes. The material is used for double-agent one-piece left and right isolated packaging or single-agent independent packaging of the dyes, can effectively isolate unfavorable influences of light and oxygen and water in air on the content, gives good preservation environment, and highly guarantees the quality and the use safety of the dyes.

Description

technical field [0001] The invention relates to the technical field of hair dye materials, in particular to a preparation method and structure of an aluminum foil material specially used for packaging hair dyes. It is mainly through the bonding of multiple layers of materials, combined with instant heating and composite molding from the outside to the inside, so that when the packaging material is used in the packaging of hair dyes, it can be used as a double-agent one-piece isolation package or a single-agent independent packaging , and can effectively isolate the adverse effects of light, oxygen and moisture in the air on the contents, and at the same time give it the convenience of carrying and use, breaking through the limitations of bottled packaging or aluminum tube packaging for hair dyes. . Background technique [0002] General hair dyes and other chemical agents are composed of chemical components. If they are accidentally exposed to oxygen and moisture in the air ...

AI Technical Summary

Problems solved by technology

[0002] General hair dyes and other chemical agents are composed of chemical components. If they are accidentally exposed to oxygen and moisture in the air during storage, or exposed to sunlight for a long time, chemical changes are likely to occur and lead to deterioration or failure. The packaging of such products is usually packaged in bottles or aluminum tubes made of opaque materials, and then placed in paper packaging boxes for display and sales. In addition to the high cost of the overall packaging, another On the other hand, it also consumes a lot of space and is inconvenient to carry

[0003] Furthermore, in terms of this type of hair dye, usually two doses are formulated with different formulations, and then the two doses are mixed and used to achieve the purpose of hair dye. Currently, a group of hair dyes on the market require Use two bottled packages or two aluminum tube packages, and then use a paper outer box to pack the two bottles of hair dye or two aluminum tube hair dyes into one, resulting in the overall packaging cost. In addition, the used empty bottles or aluminum tubes and cartons also cause problems in environmental protection. As far as industrial utilization is concerned, it is really difficult to call the ideal packaging method, and it is necessary to try to solve it and improve it.

Hair dyes are packaged in bottle-style packaging or aluminum tube packaging, which leads to high packaging costs and many shortcomings such as subsequent environmental protection problems.
