What are the principle characteristics of PVC films?

After heating and softening the PVC film, it is brought close to the medium-density fiberboard that has been sprayed with adhesive. The air between the PVC film and the adhesive film of the medium-density fiberboard is removed by vacuum, and the PVC film is tightly adhered to the medium-density fiberboard by atmospheric pressure. This technological process is called vacuum blister lamination.

·What are the characteristics of PVC blister lamination?

The adhesive used for vacuum blister lamination is vacuum blister adhesive, which is mainly composed of water-based polyurethane adhesive mixed with other resins. Theoretically, hot-melt adhesives and solvent-based adhesives can also be used, but water-based adhesives are non-toxic, odorless, reasonably priced, and suitable for mechanized operations.

The most prominent feature of this process is that it eliminates the need for spraying paint or coatings, making it a paint-free process. Besides, it can cover concave-convex grooves, curved edges, and hollow-carved parts, which is unmatched by other processes.

·Where is PVC blister lamination often used?

The vacuum blister lamination process is widely applied in the manufacturing of computer desks, speaker panels, cabinets, doors, and furniture, as well as in the processing and production of automotive interior parts.
