In a process for packaging a liquid or semi-liquid food or beverage in a container or oriented thermoplastics material with a head space above the product in the container, in which the container package is thermally processed at a temperature of 60 DEG to 140 DEG C to condition the product for storage, the material of the container body is previously heat-set to a temperature such that the thermal processing causes a volume shrinkage of 3% to 15%, and after cooling any pressure differential across the container body wall is insufficient to cause panelling. |
