Abstract: Provided is a multi-compartment tray having at least two compartments that are connected at the time of sale and then able to be split into separate, detached compartments by a user. The compartments are conjoined by a 3-dimensional wave-shaped perforation region. Each perforation wave includes a crest and a trough and perforation tabs are formed on at least some of the crests and troughs and form the point of interconnection between the compartments. In use, a user can apply leverage to the offset planes resulting in bending/snapping of the compartments relative to one another and causing the perforation break, thereby separating the compartments.

Abstract: A multilayered polymeric structure for use as a packaging container comprising a first layer of oxygen barrier material and a second protective layer bonded to the first layer where the oxygen barrier layer material is selected from the group consisting of saponified ethylene-vinyl acetate copolymer, polyamide, polyvinyl alcohol, modification products thereof, and mixtures thereof, and the second protective layer comprises a polymer and an inorganic filler in an amount sufficient to further enhance the moisture barrier property of the outer protective layer over what it would be in the absence of the filler.

Abstract: A polymeric sheet structure for use in a packaging container. The sheet contains a first layer of oxygen barrier material and a second and optionally third protective layer bonded to the first layer. The oxygen barrier layer material can be saponified ethylene-vinyl acetate copolymer, polyamide, polyvinyl alcohol, modification products thereof, or mixtures thereof, and the second and third protective layer can contain a polymer and an inorganic filler with an aspect ratio distribution in an amount sufficient to further enhance the moisture barrier property of the outer protective layer over what it would be in the absence of the filler. Also a process for protecting an oxygen or moisture sensitive material that includes the step of enclosing the material in a container that is completely or partially constructed of the sheet structure.
