Abstract:
1. A container comprising: a sidewall comprising paperboard including one or more vent(s); a shrink film inner liner having an intermediate portion peripherally affixed to the sidewall at upper and lower circumferential bands, the vent(s) being disposed within a periphery of the intermediate portion wherein the intermediate portion is adapted to separate from the sidewall with an extent of shrinkage from about 0.125 inches to about 0.50 inches such that ambient air flows through the vent(s) to form an air pocket between the sidewall and the intermediate portion wherein the form, number, and location of the vent(s) are so located such that the shrinkage of the shrink film is not unduly hindered by slow pressure equalization between ambient air and the forming air pocket.
