Problems solved by technology

[0004] The aluminized film is compounded with PE and cardboard to form an aseptic packaging composite material. Now the common aseptic flexible packaging has a low gloss and poor aesthetics.
Moreover, under the technical conditions of extrusion coating technology, the aluminized film and its printed film surface have poor bonding strength, are easy to delaminate and peel off, and cannot meet the needs of current high-end packaging products.
[0005] At the same time, after the traditional ink is co-extruded and compounded, the ink film and the printing substrate are peeled off, resulting in the coating layer and the original PET film layer not being well combined, the surface of the printed product is blistered, and the pattern is damaged, seriously Affect the qualification rate of the product

Abstract

The invention discloses a processing technology of an aseptic package with metallic luster. The technology includes the steps of: (1) compounding an aluminum plated film, PE and a paperboard together to prepare a composite aluminum plated card paper; (2) employing ink to perform printing on the surface of the composite aluminum plated card paper, wherein the ink comprises: 10-28% of pigment, 45% of polyurethane, 8.5-26.5% of n-propyl acetate, 8% of propylene glycol methyl ether, 2% of a leveling agent, 3.5% of a wetting agent, and 5% of a chelating agent; (3) compounding a PE layer and an aluminum foil layer on the other side of the paperboard; (4) compounding a PE layer on the other side of the aluminum foil layer; (5) compounding functional resin on the printed aluminum plated film surface by a multi-layer coextrusion technology; (6) cutting the obtained composite material into a coiled material; and (7) conveying the coiled material into a filling machine, and carrying out sterilization, filling, sealing and molding; and (8) sealing a drinking port. The package has metallic luster, the aesthetic properties of the aseptic package is greatly improved, and the overall value of the aseptic package is increased.

Description

technical field [0001] The invention relates to the field of packaging, in particular to an aseptic packaging process with metallic luster. Background technique [0002] Flexible packaging is a commonly used packaging form now. With the development of products and the needs of customers, flexible packaging is developing in the direction of low cost, high performance and diversified appearance. Especially the diversification of products, the appearance of flexible packaging after printing is also Need to follow diversification. [0003] Aluminized film is a composite flexible packaging material formed by coating a layer of extremely thin metal aluminum on the surface of a plastic film. Generally, aluminized film is processed in a vacuum state, and the metal aluminum is melted and evaporated at high temperature in a high vacuum state. , so that the vapor deposition of aluminum accumulates on the surface of the plastic film, so that the surface of the plastic film has a metall...
