ABSTRACT PACKAGING METHOD AND APPARATUS A package is steam-shrunk while subjected to a substantially constant sub-atmospheric pressure generated by a suction fan 22 operating at the same time as a steam generator 13 maintaining the prevailing pressure within a chamber interior 20 at a sub-atmospheric pressure in the presence of steam. The low pressure of the steam ensures that its temperature is well below the boiling point of water and avoids thermal damage to the material of a container 12 being shrunk.
