Problems solved by technology

The aluminum film process in the plastic box industry adopts hot stamping and cold stamping. The cost of cold stamping is high and the adhesion is not good. Okay, the area is a little bigger, and ordinary machines can’t be ironed, and special machines are needed to produce it, not to mention the high cost, and the quality is not stable
In addition, in order to prevent the films from rubbing and scratching each other during the production process, the production of plastic boxes generally requires a layer of protective film on the surface of the film. , which has a great impact on the quality of the later products. If it is ironed on the reverse side, the front side will look poor, with uneven feeling and uneven color

Abstract

The invention discloses a coated photographic film with a window, a preparation method and an application thereof. The preparation method comprises the following steps of: (1) offset printing: printing a to-be-patterned part on a photographic film with ordinary ink, and printing a to-be-windowed part with special ink to obtain the photographic film; (2) coating: laminating a film on a reverse side of the photographic film obtained in step (1); (3) die cutting: penetrating through the part which needs to be windowed in the film; and (4) windowing: tearing down the film which is penetrated through in step (3) to obtain the coated photographic film with the window. The coated photographic film with the window is prepared by using two different inks, the preparation method is simple and easy to operate, the prepared photographic film is good in adhesive force, uniform and bright in color and attractive in appearance.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a film-coated film with a window and a preparation method and application thereof. Background technique [0002] There are many packaging plastic boxes with windows on the market, which can not only allow customers to see the inner product, but also fully package the product, allowing consumers to see the inner real product, making consumers feel real and at ease. It is a kind of It is an ideal packaging method, but the traditional packaging method of window opening and film sticking has high production costs and will cause material waste. [0003] Aluminum film is widely used in the field of food and pharmaceutical packaging due to its beautiful appearance, good sealing performance, good physical properties such as water vapor transmission rate and oxygen transmission rate. The aluminum film process in the plastic box industry adopts hot stamping and cold stamping. The cost o...
