Printing film manufacture method and manufacture machine for implementing the method

Abstract

The invention relates to a printing film manufacturing method and a manufacturing machine for implementing the method. The method includes the steps of feeding a first film material roll, printing, drying and color fixing, feeding a second film material roll, mutually sticking, cutting, and the like. The manufacturing machine includes the composition mechanisms like a multi-head printing device, a first rotating wheel group, a second rotating wheel group, a cutting device, and the like. In the invention, a semi-finished product needed for manufacturing the printing film can be fast manufactured into a finished product by printing, sticking film and cutting. Besides, the printing film manufactured by the invention can be used as a paster in a film so as to lead a matter in the injection molding to be capable of accomplishing mutual fusion with the printing film preplaced in a die.

Description

technical field [0001] The present invention relates to a printing film manufacturing method and a manufacturing machine implementing the method, which are used to manufacture in-mold stickers that can be preset in an injection molding mold. The present invention particularly relates to a printing film manufacturing process that provides a complete manufacturing process Method and printing film manufacturing machine. Background technique [0002] The application of printed stickers is quite extensive. For example, the packaging appearance of daily necessities can be seen everywhere, such as bottled drinks, tissue boxes, ice products, etc. At present, most of the packaging methods used for such products are stickers first. After the printing is completed, it is then wrapped or attached to the appearance of the main body of the package. For example, the plastic printing film that keeps the appearance of the bottle is one of them. Another type of sticker packaging application i...

Problems solved by technology

In order to meet the above needs, the present invention develops a printing film suitable for food packaging. It mainly uses two opposite films to completely cover the printing layer to prevent the printing layer from being damaged by the temperature in the environment. , Humidity changes and exudation can increase the safety of food. However, the production process of this kind of printing is different from that of the existing printing stickers, so special manufacturing machines are needed to achieve it; the existing printing The manufacture of stickers is mainly through the process of feeding, printing, color fixing, etc. to make semi-finished stickers, and then use another machine to coat and oil to form a protective layer according to requirements, and then use another machine to finish the finished product The cutting of each section of the manufacturing process needs to repeatedly concentrate the semi-finished products, and then transport them to another machine for the next station of processing operations. In the manufacturing process, it can be said to be time-consuming and laborious, and too much handling process will easily lead to semi-finished products. Damaged; again, the present invention mainly manufactures a kind of printing film with biaxially stretched polypropylene (Bi-axial OrientedPoly Propylene, BOPP) as base film layer and cover layer, the characteristic of this kind of print film is that base film layer and covering The layers are the same material, and when they are heated and laminated, they can produce a proper mutual melting effect and can effectively cover the printing layer. Therefore, the continuous manufacturing process is absolutely important for the output quality of this printing film. Moreover, if it can be cut and shaped into finished products when the production is completed, the damage of the finished product will be greatly reduced, and the cost of handling and labor will also be saved, and the production efficiency will also be improved.
