Printing and forming process of environment-friendly APET plastic products

Abstract

The invention relates to a processing process of APET plastic products, in particular to a printing and forming process of environment-friendly APET plastic products. The printing process comprises the following steps:1) making an APET plastic plate; 2) embossing a leading wire on the APET plastic plate and laminating a film on the APET plastic plate; 3) cutting the APET plastic plate; 4) carrying out silk-screen printing; 5) coating the APET plastic plate with a protective film layer; 6) pressing sides; 7) carrying out die-cutting forming; and 8) carrying out high-frequency splicing. According to the process, the APET plastic is used as an original material of the plastic products so that the environment can be protected, the resources can be recycled, and the processing cost can be reduced; the reasonable printing process is adopted so that the pattern printing and the pattern die-cutting forming of the APET plastic sheet material can be smoothly completed in shortest time and in most convenient operation steps; and the most suitable forming process is adopted, so that the APET sheet material can be stereoscopically formed smoothly, and the APET plastic products which are attractive in printing, stable in quality and energy-saving can be obtained.

Description

Technical field [0001] The invention relates to a processing technology of APET plastic materials, in particular to a printing and molding technology of environmentally-friendly APET plastic products. Background technique [0002] With the rapid development and progress of my country's packaging and printing industry, for the increasingly accelerating pace of life, plastic sheet packaging with higher convenience is also rapidly emerging. Packaging boxes or plastic products made by plastic processing are waterproof, light and easy to carry. , The printing styles are many and beautiful, which makes the overall packaging effect excellent and attracts consumers. However, there are still several drawbacks in the current development of the plastic printing industry and resource problems. [0003] First of all, in terms of plastic selection, most plastic packaging products or products have poor degradability and are difficult and costly to recycle. After use, they will become waste garbage...

Problems solved by technology

[0003] First of all, in terms of plastic material selection, most plastic packaging or products have poor degradability and are difficult and costly to recycle. In terms of the basic development strategy, these plastic products are not conducive to the development of environmental protection concepts, so they cannot be produced and used for a long time

[0004] Secondly, there are also certain defects in the field of plastic processing. When plastic sheets are formed, heat-sealing joints are required. The traditional heat-sealing joint method is to use an ordinary heat-sealing machine to heat the plastic at high temperature to complete the heat-sealing joint, but this The working time of this heat-sealing method is too long, the efficiency is low, and the heat-sealing effect is not good for slightly thicker sheets, resulting in the failure to improve the overall production efficiency; however, if the high-frequency heat-sealing method is used to complete the heat-sealing joint , can improve the packaging efficiency to a certain extent, but not all plastic materials can be sealed by high-frequency welding and sealing, such as PVC and PDVC plastics containing chlorine, which will affect human health during high-frequency welding Chlorine-containing compounds, that is to say, from the perspective of comprehensive production efficiency and human health, the optional processing methods of applicable plastics are also subject to many limitations

[0005] Secondly, there are certain limitations in the printing method of plastics. At present, printing graphics and texts on plastic sheets is usually directly printed on the product through the spraying process, but the pattern printed by the spraying process is not clear enough, and spraying The process will also pollute the environment; if the graphics and text are printed by transfer printing, it will not be possible to reasonably control the operation process to obtain an excellent printing effect
