Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of environment-friendly aluminum foil packaging material preparation technology, to solve some unreasonable factors in the process of the existing aluminum foil packaging material preparation proposed in the above-mentioned background technology, the existing aluminum foil packaging material preparation In the process, the core material ingot and the skin material wrapped on both sides are stacked together at a certain coating ratio, and the combination of the two is realized under certain temperature and pressure conditions. This preparation method has low production efficiency and high yield. Low, which reduces the efficiency; the existing aluminum foil packaging materials have insufficient product performance stability after preparation, and the existing aluminum foil packaging materials have poor stretch resistance after preparation

Abstract

The invention discloses a preparation technology of an environment-friendly aluminum foil packaging material. The preparation method comprises the following steps that an industrial aluminum foil is used as a base material, the aluminum foil is uncoiled; corona treatment is carried out; gravure printing and drying treatment are carried out; a protective layer coating is carried out; drying treatment is carried out again; a solvent-free adhesive coating is carried out; drying treatment is carried out on the aluminum foil with the solvent-free adhesive coating; and coiling and aging are carriedout. According to the method, the production efficiency is high, and the product performance is stable; pollution caused by contacting of an outer-layer ink and an inner-layer solvent-free adhesive during the coiling of the aluminum foil is prevented by the protective layer coating, so that an aluminum foil base material is protected and prevented from corroding; the solvent-free adhesive is used,so that the residual solvent is effectively reduced, and the cost is reduced; the solvent-free adhesive does not need to be diluted, the solvent-free adhesive can be directly produced on a machine, so that the labor of operating workers to prepare the adhesive is reduced; and meanwhile, the concentration of the solvent in the working site air is also reduced, and the working intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a preparation technology of an environment-friendly aluminum foil packaging material. Background technique [0002] A hot stamping material that is directly rolled into thin sheets by metal aluminum, and its hot stamping effect is similar to that of pure silver foil hot stamping, so it is also called fake silver foil. Due to the soft texture, good ductility and silvery white luster of aluminum, if the calendered sheet is mounted on offset paper with sodium silicate and other substances to make aluminum foil, it can also be printed. [0003] However, there are still some unreasonable factors in the preparation process of the existing aluminum foil packaging materials. In the preparation process of the existing aluminum foil packaging materials, the core material ingot and the double-sided wrapped leather material are laminated at a certain coating ratio. Together, and realize th...
