Embodiment 1

[0008] Produces film labels with single-sided metal graphics. 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 coating thickness is preferably 300 to 500 angstroms. Thereafter, the aluminum-plated insulating film is taken out from the vacuum device, and printed on the aluminum-plated surface of the insulating film by a printing method known in the art, and a polyamide ink protective layer of predetermined pattern or pattern is formed thereon. The predetermined figure or pattern corresponds to the desired figure or pattern. Then, the insulating film is introduced into an etching tank equipped with sodium hydroxide, and the aluminum layer outside the area covered by the polyamide ink protective layer is etched away to obtain the required metal figure or pattern on the aluminum-plated surface of the insulating film, instead of obtaining bronzing or The visual effect of partia...

Embodiment 2

[0010] Produces film labels with double-sided metal graphics. In a vacuum device, an aluminum layer is evaporated on both sides of a flexible insulating film made of polyethylene terephthalate (PET), and the coating thickness is preferably 300 to 500 angstroms. PET is used as the film material. Due to its transparent properties, after the coating on both sides of the film is corroded by acid or alkali, the reaction part will appear transparent (one side can be transparent or both sides can be transparent at the same time), so that the predetermined special visual effect can be achieved. Those skilled in the art can understand that, according to needs, the plating layer and / or the thickness of the plating layer on both sides can also be the same or different. During evaporation, a base that can rotate and support the insulating film can be set in the vacuum evaporation device. After one side of the insulating film is coated, the base is rotated 180 degrees to evaporate the othe...

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...
