Surface treatment
Corona treatment is a high frequency discharge that increases the adhesion of a plastic surface.
Atmospheric plasma treatment systems increase surface receptiveness & adhesion to inks, coatings, adhesives, laminates, paints, & more. Surface modification provides manufacturing, assembly and decorating advantages by cleaning, etching and functionalizing surfaces.
Flame treatment is ideal for functionalizing surfaces of films and objects. Common materials flame treated in the converting industry include BOPP, PET, OPP, PE, coextruded films, paperboard, metal foil to increase adhesion.
Laser engraving;is to cut through and engraves the material surface. Following the engraving line or area in digital design, the laser vaporizes a thin layer of the material surface.
