Embodiment 1

[0056] The invention provides a method of gravure printing on the surface of aluminum foil after pre-compositing, and the details of the printing method are as follows:

[0057] Step 1) Gluing treatment: Glue the 20μm thick LLDPE through the glue roller on the printing machine. The glue used for gluing is adhesive. The type and ratio of adhesive are SY-03G: SY-03B: ethyl ester = 20:4.8:28;

[0058] Step 2) Composite treatment: Laminate the glued LLDPE and AL aluminum foil with a thickness of 20 μm to form a 0.02mmAL aluminum foil / 0.02mmLLDPE semi-finished composite film;

[0059] Step 3) The first aging treatment: the 0.02mmAL aluminum foil / 0.02mmLLDPE semi-finished composite film made by compounding in step 2 is sent to the material rack of the curing room for hanging curing, and the semi-finished composite film is suspended on the material rack of the curing room. The time is 30 hours, and the temperature for curing in the curing chamber is 45°C;

[0060] Step 4) Gravure p...

Abstract

The invention discloses an intaglio printing method for the surface of a pre-compounded aluminum foil. The intaglio printing method comprises the steps of gluing treatment, compounding treatment, primary curing treatment, intaglio printing treatment, secondary curing treatment, cooling treatment, slitting treatment and final inspection treatment. The whole printing method is simple and suitable for a large-scale printing process. In addition, before the AL aluminum foil is printed, LLDPE is firstly glued, then the glued LLDPE and the AL aluminum foil are compounded and attached, and the curing and intaglio printing procedures are carried out. The strength of the AL aluminum foil film in the machining process is improved through compounding of the LLDPE and the AL aluminum foil, and wrinkles or breakage during printing of the AL aluminum foil can also be avoided.

Description

technical field [0001] The invention relates to the technical field of aluminum foil printing in the printing and packaging industry, in particular to a gravure printing method on the surface of aluminum foil after pre-compositing. Background technique [0002] Aluminum foil composite film is the most commonly used composite roll film, usually containing pure aluminum (AL) and aluminum plating (VMPET), [0003] At present, aluminum foil composite films are widely used in various packaging film products, including food packaging bags, low-temperature vacuum freezer bags, composite roll films, aluminum foil bags, etc. [0004] Generally, the manufacturing process of aluminum foil composite film is made by aluminum foil printing. The existing aluminum foil printing is to directly use aluminum foil as the substrate, and then print on the surface of the aluminum foil, and then compound the printed aluminum foil semi-finished product with other substrates. Production, this foil p...
