ABSTRACT:
A package for perishable products which can readily be prepared for home freezing is comprised of a relatively rigid tray and a flexible cover, the cover having a hole covered by a removable, replaceable seal. The tray is provided with collapsible supports, which hold the cover above the perishable product on the tray during fresh storage, but which can be readily collapsed in order to provide maximum expulsion of air from the package in preparation for freezing. The atmosphere in the package may be modified so as to inhibit bacterial decay of the product and/or to enhance its appearance. The package is prepared for freezing by removing the seal, collapsing the supports and expelling as much of the atmosphere in the package as possible, and then replacing the seal.
