PVC (Polyvinyl Chloride) is a thermoplastic with excellent mechanical properties and chemical stability, so it is widely used for various types of printed materials, packaging materials, cards, stickers, etc. PVC lamination is a common process of combining PVC sheets with other materials to increase the strength, durability, and decorative effect of the product. The process flow of PVC lamination will be described below.

Preparing the PVC sheet

The first step in PVC lamination is to prepare the PVC sheet and the substrate to be laminated.PVC sheets usually come in different thicknesses and colors, so choose the right PVC sheet according to your actual needs. The substrate can be wood, metal, glass, stone, or other materials, according to different product requirements to choose the appropriate substrate.

Surface treatment

Surface treatment is the key step to ensure that the PVC sheet and the substrate can be firmly bonded. PVC sheets and substrates are usually cleaned, sanded, and coated with special adhesives. Cleaning removes dust and impurities from the surface, sanding increases the roughness of the surface, which facilitates the penetration and adhesion of the adhesive, and the coating of the adhesive improves the bonding strength between the PVC sheet and the substrate.

Lamination

Lamination is the process of pressing the surface-treated PVC sheet to the substrate. The substrate is first coated with a special adhesive, and then the PVC sheet is placed on top of the adhesive, which is heated and pressurized to make a strong bond between the PVC sheet and the substrate. In this process, the control of temperature and pressure is very important, they directly affect the lamination effect and product quality. Specialized laminators or heat presses are usually used for the lamination operation.

Molding

After lamination, the product needs to be molded to meet different product requirements. Molding can be done by cutting, stamping, thermoforming, and other processes to process the laminated products into the required shapes and sizes.

Conclusion

PVC lamination is a common and important processing process, by combining PVC sheets with other materials, various personalized products can be made. However, when performing PVC lamination processing, the process parameters of each link must be strictly controlled to ensure product quality and production efficiency.
