ABSTRACT:
A method and apparatus for packaging perishable goods such as red meat. The packaging contains a base (1), a lid (3), and a flexible web (5) of gas permeable material held over the goods (7) so the goods are held to the base (1). A suitable gas is retained within the packaging which can permeate the flexible web (5) to enhance the keeping properties of the goods (7). The method and apparatus provide that the flexible web (5) is held between a pair of web holding means (65) and stretched towards the goods (7) as the lid (3) is moved to close the package, all within a gas flushing chamber. Such stretching holds the goods (7) firmly to the base (1).
