A substantially paper-based composite container for an off-gassing product includes a paperboard can body having a substantially gas-impervious liner attached to an inner surface thereof, and a pair of substantially paper-based end closures attached to the opposite ends of the can body, each end closure defining a generally cylindrical sealing panel in contact with an inner surface of the can body. Heat-sealable materials are disposed on opposing surfaces of the sealing panel and can body. The sealing panels of the end closures are attached to the can body by heat seals. The heat seal for at least one of the end closures is discontinuous such that at least one vent channel extends through the heat seal so as to establish fluid communication between an interior of the composite container and the environment outside the composite container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.

A baking container having one or more rupture lines for ease of removal and separation from a baked foodstuff is described herein. The baking container has a sidewall and a planar bottom face. One or more rupture lines may run down a height of the sidewall and across a portion or all of the planar bottom face. Rupture lines having even spacing may form a strip, and the strip may have a pull tab to easily tear through the sidewall. The strip may be reinforced with a string or ribbon. The rupture lines may be formed by perforating or weakening areas of the baking container.

A wound package construct includes a first wound strip of package material that establishes an inner liner layer, a second wound strip of material that establishes an intermediate bodystock layer, and a third wound strip of material or cover strip that covers a seam formed by the wound bodystock layer but that does not cover all of the outer surface area of the wound bodystock layer. Therefore, the width of the cover strip is less than the width of the bodystock strip. As a result, the cover strip is not wide enough to cover the entire outer surface of the wound bodystock layer such that, after the cover strip is wrapped to cover the spiral bodystock seam, areas of the bodystock layer remain exposed between the two opposed length-wise edges of the cover strip.
