Abstract

For the improvement of the adhesion to ethylene vinylacetate copolymer (EVA), poly (ethylene terephthalate) (PET) films were treated with low pressure plasmas in a laboratory batch reactor and in a pilot scale semi-continuous treatment system. The effects of the treatments were investigated by mechanical testing of the PET-EVA laminates, by XPS, by chemical derivatization for XPS, and by contact angle measurements including a data processing for the determination of Lewis acid/ base properties of the surfaces. It was found that the adhesion between the polymer surfaces seems to be based on rather specific interactions which ask for certain conditions for the surface treatment. The differences between the batch treatments and the semi-continuous treatments are discussed.
