PET folding box production process:
1. Plastic box platemaking: CTP platemaking is commonly used in plastic box platemaking.
2. Plastic box selection materials: Generally, plastic box packaging is made of PET, PVC, PP and other materials. The thickness of PVC and PET is usually 0.10-0.0.55. PP can be as thick as 0.75MM because the material is too thick. The plastic box came out too rigid, and the appearance also looked dull.
3. PET folding box printing: the outside of the plastic box will not be printed, at most it is only silk screen. Because the plastic box is an outer packaging box, the printing requirements are very high.
4, PET folding box surface treatment: plastic box packaging usually requires surface treatment, the common ones are over-gloss glue, over-mat glue, over UV, over-varnish, over-mat oil. This is what we call offset printing.
5. PET folding box beer (die cutting): Beer is a more important part of the printing process. If you want beer to be accurate, you must use a knife mold to make it accurate. If the beer is not accurate, the beer is biased, and the beer continues to seriously affect the subsequent processing.
6. PET Folding Box Lamination: Usually printed products are filmed before beer, but the plastic box is beer first and then filmed. One is to avoid flower packaging, and the other is to pay attention to the overall beauty of the plastic box. It must be handmade to achieve a certain aesthetic appearance.
7. PET folding box sticking box: After laminating machine, it needs to go through the box sticking process (automatic sticking box, manual sticking box). PET folding box sticking box needs to pay attention to the choice of glue. Different materials require different types of glue.
