Abstract
A package for storing oxygen sensitive goods includes a first web in the form of a tray which may include flanges, a valve or valves, carbon dioxide, a good or goods, such as red meat or other oxygen sensitive food and non-food products and a second web sealed to the tray in the form of a gas impermeable film to which has been fitted a one-way valve. The pressure within the package increases as a gaseous modified atmosphere is introduced through the one-way valve in the tray. The oxygen within the barrier bag is forced out of the one-way valve located on the film. A vacuum applied to the one-way valve on the film facilitates the removal of oxygen. Additionally, the atmosphere within the bag can be monitored by locating sensors within the gas stream leaving the one-way valve in the film as it leaves the interior of the package.
