A packaging material is provided including a substrate, and an oxygen transmission inhibiting layer that is carried by the substrate. The oxygen transmission inhibiting layer is formed of a composite material including a linear polysaccharide medium within which one or more additives are dispersed. The composite material is capable of forming a substantially continuous film to provide a barrier to transmission of oxygen gas. The oxygen transmission inhibiting layer is configured within the packaging material at a thickness that is efficacious in inhibiting the transmission of oxygen gas therethrough. A packaging device has two or more component parts, at least one of which is formed of the packaging material. The component parts of the packaging device are shaped and/or configured to be assembled to define an interior region within which goods are to be contained.

The invention relates to methods for lowering the melt viscosity and thereby improving heat-sealability of a polyester. The invention also relates to a method for manufacturing a heat-sealed container or package from fibrous-based, polyester-coated packaging material, and a method for heat-sealing polyester. The solution according to the invention is subjecting polyester to electron beam (EB) radiation. The lowered melt viscosity allows a lower heat-sealing temperature, and permits sealing of polyester to an uncoated fibrous surface. The preferred polyester for the invention is polylactide, as such or as blended with another polyester.
