Improvements in or relating to packaging.

摘要

A method of packaging a heat transformation product, such as popcorn (6), in a rigid container is described. The mouth of a bag (4) portion formed from a film of heat-extensible plastics material is contacted with the mouth of the container in which the product is situated. The bag portion is collapsed into the container by a pressure differential so that the bag substantially follows the interior contour of the container and the product. The interior volume of the container and the bag portion are at least sufficient to contain the product in its heat-transformed state. Packages produced by the method are also described.
