Coated, drunk packed multilayer rigid container body, and methods for reducing gas or vapor permeability through a multilayer rigid container body, for packaging a beverage, and for producing recycled container plastic

摘要

"METHOD OF MULTIPLE LAYER CONTAINER, PACKED DRINK, AND METHODS TO REDUCE GAS OR STEAM PERMEABILITY THROUGH A MULTIPLE LAYER RECIPIENT BODY, TO PACKED RECYCLED BEBED The multi-layer coated structure comprising a polymeric base layer, a zero valence material barrier layer, and a topcoat over the zero valence material barrier layer, the topcoat comprising a soluble compound capable of reducing the gas or vapor permeability of the multilayer structure. The barrier layer against zero valence material can also improve the barrier to UV light. Also described is a method for improving the gas or vapor barrier properties and the UV light barrier properties of an inorganic / polymer multilayer structure. According to one embodiment, Si-coated poly (ethylene terephthalate) containers are coated with a gas or vapor barrier enhancing topcoat. Also described is a method for recycling containers coated with a barrier layer against zero valence material.
