ABSTRACT:
A method of producing packaging in which the goods to be packaged are engaged against a rigid base and a flexible material is held taut over the goods. Portions of the flexible material near the side edges thereof are engaged and moved to a position below the top of the goods. The intermediate portions of the flexible material are tensioned and stretched thereby compressing the goods to the base. A lid is applied over the base so there is a space between the lid and the flexible material which is secured to the base below the goods to maintain the goods against the base. A gas is charged into the space to preserve the goods, ad the lid and flexible material are sealed to the base with the gas in the space.
