PLASTIC CONTAINERS WITH GAS BARRIER COATING AND OPTIONALLY HYDROPHILIC INSIDE COATING |
摘要 |
The invention is directed to a process for producing a plastic container with a barrier coating comprising 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 polyvinyl alcohol on the first polyvinyl acetal layer; c) applying at least one top coating layer of a second polyvinyl acetal on the polyvinyl alcohol layer. The surface of the plastic container may be pre-treated before coating. In addition to the barrier coating, the surface energy of at least a part of the inside surface of the plastic container may be increased by applying at least one inner hydrophilic coating layer. |
