PROCESS OF COATING PLASTIC CONTAINERS WITH GAS BARRIER COATING TO ACHIEVE IMPROVED MOISTURE RESISTIVITY

摘要

The invention is directed to a process for producing a plastic container with a barrier coating comprising the steps a) applying at least one coating layer of a first polyvinyl acetal on at least a part of the plastic container; b) applying at least one coating layer of vinylalcohol/vinylacetate/ethylene terpolymer (PVAE) on the first polyvinyl acetal layer; c) applying at least one top coating layer of a second polyvinyl acetal on the PVA Elayer.
