Example Embodiment

[0007] Example 1

[0008] Production of film labels with single-sided metal patterns. In a vacuum device, an aluminum layer is vapor-deposited on one side of a flexible insulating film made of materials such as thermosetting resin, and the thickness of the plating layer is preferably 300 angstroms to 500 angstroms. After that, the aluminum-plated insulating film is taken out of the vacuum device, and printing is performed on the aluminum-plated surface of the insulating film using a printing method known in the art to form a polyamide ink protective layer with a predetermined pattern or pattern on it. The predetermined figure or pattern corresponds to the desired figure or pattern. Then, the insulating film is introduced into the corrosion tank equipped with sodium hydroxide, and the aluminum layer outside the area covered by the polyamide ink protective layer is corroded and removed to obtain the required metal pattern or pattern on the aluminum-plated surface of the insulating f...

Example Embodiment

[0009] Example 2

[0010] Production of film labels with double-sided metal patterns. In a vacuum device, an aluminum layer is vapor-deposited on both sides of a flexible insulating film made of polyethylene terephthalate (PET), and the thickness of the plating layer is preferably 300 angstroms to 500 angstroms. Using PET as the film material, due to its transparency, after the coating on both sides of the film is corroded by acid or alkali, the reaction part appears transparent (one side is transparent or both sides are transparent at the same time), which can achieve the predetermined special visual effect. Those skilled in the art can understand that the plating layer and / or the thickness of the plating layer on both sides may also be the same or different according to needs. During evaporation, a pedestal that can rotatably support the insulating film can be set in the vacuum evaporation device. When one side of the insulating film is coated, the pedestal is rotated 180 degree...

Abstract

A process for preparing film label includes such steps as providing a film, vacuum evaporating of a metal layer on the film surface, printing a chemical corrosion resistant protecting layer whose shape is a needed graphics or pattern, chemical corroding to remove uncovered metal layer, and attaching the obtained metal graphics or pattern onto a paper substrate.

Description

technical field [0001] The invention relates to a method for making a film label. Background technique [0002] Film labels can be widely used in trademarks, seals, various types of packaging paper, etc. In the traditional film label printing process, metallization treatment such as hot stamping treatment or partial transfer treatment is required to obtain a certain visual effect, but both hot stamping treatment and partial transfer treatment require high processing costs and long processing time time. Contents of the invention [0003] The purpose of the present invention is to provide a low-cost and high-efficiency film label manufacturing method. [0004] The manufacturing method of the film label of the present invention comprises the steps of: providing a film; vacuum-depositing a metal coating on the surface of the film; printing a chemical corrosion-resistant protective layer on the metal coating, the shape of the protective layer corresponding to the required met...
