ABSTRACT:
A process for packaging bulk commodities such as meat comprises vacuum sealing the commodity into a bag of plastics material and then causing the material of the bag to expand by a further reduction in pressure of the environment surrounding the bag. The material expands into contact with heaters which heat the material and when the environment surrounding the bag is returned to normal pressure, the material closely encloses the commodity.
