ABSTRACT:
A method of packaging goods such as red meats is disclosed. The goods (5) are packaged on a base (1) with an inner skin lid (11) which at least partially skin packs the goods (5) to the base (1) to hold the goods (5) to the base (1). An outer lid (7) is placed over the inner skin lid (11)and gas pressure is reduced therebetween causing the inner skin lid (11) to be urged relatively towards the undersurface of the outer lid (7). The outer lid (7) is then sealed to the inner lid (11) and the base (1). The inner skin lid (11) is of a material which will allow a required gas such as O.sub.2 to penetrate the inner skin lid (11) when the outer lid (7) is opened, removed or ruptured to, in turn, allow the red meat, if discolored, to bloom to a red color. The method enables unwanted gases such as O.sub.2 to be substantially excluded from the packaging until the outer lid (7) is opened, removed or ruptured.
