process to improve the adherence of fine films deposited by the process pecvd in packages PET and resulting
NOVELTY – The PET packages PECVD thin film adhesion enhancement comprises oxygen plasma processing of the packages prior to application of the polyethylene film, in order to incorproate functional groups and also increase surface roughness. Also claimed is the product of the procss. CLAIMED PRODUCT – The product acquires a carbon film via the hydrogenated amorphous carbon plasma generated by acetylene and argon gases. USE – In polymer processing.
Main Application Field
A92 (Packaging and containers – including ropes and nets.); A17 (Polymers of unsubstituted aliphatic monoolefins; including polyethylene.); A23 (Polyamides; polyesters. (including polycarbonates, polyesteramides); alkyds; other unsaturated polymers.); A35 (Other processing and general – including vulcanisation, welding of plastics and adhesive processes. Testing.)
