Problems solved by technology

However, on some film materials, such as: OPP, the holographic pattern is molded by direct pressing after preheating. Due to the characteristics of the material, the actual processing effect is not satisfactory, and in order to make the holographic pattern on the material The pattern layer is deep, and the operator often needs to carry out long-term preheating temperature fine-tuning work
This increases the production cost of holographic OPP film materials, thus limiting the scope of application

Embodiment Construction

[0018] The content of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Set up one mother film unwinding device and one OPP film unwinding device respectively. First introduce the OPP film into the preheating roller group, then introduce the OPP film into the existing molding roller group that removes the holographic plate, and at the same time introduce the mother film into the molding roller group, so that the mother film and OPP film can be pressed at the molding roller group. Synthesis of bilayer membranes. The double-layer film body is introduced into the cooling roller group and the traction roller group in sequence, and the double-layer film body is manually peeled into the parent film and the finished film at the output of the traction roller group, and the parent film winding device and the finished film winding device are introduced correspondingly. device.

Abstract

The invention provides a process for processing holographic patterns on an OPP thin-film material. The holographic transfer printing process comprises the following steps: 1) a mother film with the holographic patterns and an OPP thin-film to be processed are unrolled respectively; 2) the OPP thin-film is preheated; 3) the mother film and the OPP thin-film are pressed together, thus forming a double-layer film body; 4) the double-layer film body is cooled; 5) the double-layer film body is stripped into the mother film and a finished product film; and 6) the mother film and the finished product film are rolled up respectively. By adopting the process, the holographic patterns with good effect can be processed on the OPP thin-film material, and a machine for performing the process has simple structure, which can effectively reduce the input cost of an enterprise. Moreover, the mother film can be used repeatedly, the production process is easy to control, and the process overcomes the deficiency of processing on the OPP thin-film in a molding plate roller pressing mode.

Description

technical field [0001] The invention relates to a process for processing a holographic pattern on an OPP film. Background technique [0002] The processing of the holographic pattern on the existing film material is realized by the holographic molding machine, and its working principle is as follows: the holographic molding machine is provided with a molded plate roller, and the molded plate roller is provided with a holographic plate, and the molded plate with the holographic plate is used. The plate roller presses the preheated film material, and the corresponding holographic pattern can be pressed on the film material. On the basis of this direct embossing method, the applicant has developed a molded plate roller (patent application number: 200710031313.3, name: holographic molded plate roller) specially used for a double-molded station holographic molding machine. 2 sets of molded plate rollers can produce seamless holographic patterns. It has been verified by practice...
