Furniture profiles are often made of materials such as medium-density fiberboard (MDF), particle board, plastics such as PP and PVC, and more recently combinations of plastic and wood, known as wood plastic composites (WPC). They can be used as furniture finishing or edge strips or as panels for interior design. Profiles are given a decorative finish in the wrapping process; the wrapping film is continuously coated with adhesive in the wrapping machine and evenly applied to the profile by pressure rollers.
Openair-Plasma® provides effective pre-treatment of furniture and window profiles just before pressure is used to apply the film. This makes it possible to use solvent-free adhesive on otherwise non-polar profile surfaces. No additional application of adhesion promoter (primer) is needed.
The advantages of Openair-Plasma® in profile wrapping include in particular reliable, continuous process sequencing and a simple, reproducible process.
