Abstract
A process for the pretreatment of a polyolefin product before coating consisting essentially of the steps of treating the surface of the polyolefin product before coating using an organic solvent having a solubility parameter (SP value) equal or similar to that of the polyolefin and subsequently applying a plasma treating thereto in the presence of an active gas by microwave treating the active gas under vacuum. As a result of the process, the surface of the polyolefin product is activated and the adhesion of the coating film is improved.
