Plasma, Flame & Corona Pretreatment for Surface Treating Plastics

Generally, plastics have chemically inert and nonporous surfaces with low surface tensions. This makes them nonreceptive to bonding with inks, adhesives, coatings, and other substrates.

Polyethylene and polypropylene for example have very low surface energy. Pretreatment of these and other engineered plastics improves bonding prior to printing, coating, and laminating. The best type of surface treater for your application will depend on several variables

If your application requires spot treatment of an object, air plasma and flame pretreatment systems can be mounted in a stationary position or integrated with a robot for precise treatment patterns. Candidates for this type of surface treatment include injection molded, blow molded, and thermoformed parts. ABS, ASA, EPDM, EVA, HDPE, LDPE, PC, PE, PET, PMMA, PP, PS, PU, PVC, PBT and TPU are materials that have proven receptive to these types of surface treatments.

For applications treating roll to roll film and webs Corona treaters are the most popular pretreatment choice. And Plasma treaters and Flame treaters can also be used to improve the adhesion of plastics.
