Abstract

A method of packaging goods including placing goods such as meat over a base, applying a flexible web of gas permeable skin wrapping plastics material over the base and the goods, evacuating air or gas from between the base and the skin wrapping so as to allow the skin wrapping to flexibly displace onto the goods and to at least partially skin pack said goods. A lid is then applied over the skin wrapping and spaced therefrom. A gas is provided in the space between the lid and the skin wrapping to enhance the keeping properties of the packaged goods by permeating the skin wrapping. The lid is sealed to the base so that the space is permanently retained, the skin wrapping is attached relative to the base. Following discoloration of the packaged goods over a period of time, a fresh gas is allowed to enter the package and contact the surface of the goods within the skin wrapping without removal of the skin wrapping, whereby the color of the goods is improved.
