The Packaging industry needs solutions where adhesives and printing on packaging are reliable and remain effective for lifetime of the package. Increasing the industry relies on plasma surface treatment to ensure the effective marking and sealing of packages.
Applications such as printing use-by dates on plastic caps, decorative printing on packaging, whether on metal, plastic or glass materials all require surface preparation.
Plasma surface treatment can reduce the amount of adhesive or ink required. Plasma treatment increases the surface energy of the material, increasing the wettability of the surface so that the adhesive or ink spreads out more across it. This can reduce the bond line thickness which therefore requires less adhesive/ink to be applied.
There are a host of surface treating technologiesavailable, but ultimately your applicationwill determine which technology is best.
