摘要
A laminated packaging material for liquid-tight, dimensionally stable packages has superior gas-barrier properties, particularly oxygen barrier properties. The laminated packaging material includes a core layer and a barrier layer juxtaposed to the core layer. The barrier layer is formed from a polyvinyl alcohol, a polysaccharide and a cross-linking agent, the polysaccharide being chitosan and the cross-linking agent being a dialdehyde compound. A method for making the laminated packaging material is also disclosed.
