ABSTRACT:
The invention comprises improved packaging for goods such as, for example, meats, and method and apparatus for producing such packaging. The package comprises a base over which the goods are placed. A web of flexible material is positioned over the goods, with the web being in tension and tightly engaging and compressing the goods to the base. The side portions of the web are secured to the base at positions below the top of the goods. A lid is positioned over the base and the web, and is sealed to the base and spaced from the web. The space is charged with a gas enhancing the preservation of the goods, with the gas preferably being at a pressure higher than the pressure under the web so that the goods are retained on the base both by the tension in the web and by the pressure differential which serves to further hold the goods on the base.
