A method and apparatus for vacuum-packaging and heat sealing a soft product, particularly a soft product comprised substantially of fabric or other similar sheet material (referred to herein as "soft product"), having a substantially impervious outer covering in an impervious packaging barrier bag, which provides a packaged product which is compact and uniformly shaped. An air flow panel is inserted between the barrier bag and the product to permit air flow between the impervious layer of the soft product and the impervious layer of the barrier bag such that there is even air flow from the barrier bag during the evacuation of air from the barrier bag during vacuum-packaging. A packing frame is used during vacuum-packaging which assists in creating a compact, uniformly shaped vacuum-packed soft product.
An apparatus for vacuum-packing an uncompressed soft product of a given height in a barrier bag, comprising:
A vacuum-packaging frame for creating a compact, uniformly shaped packaged soft product of a selected height, comprising a horizontal base panel, a side wall extending vertically from the base panel to a height substantially equal to said selected height of said soft product, and a top panel hingedly attached to the side wall and closeable over the base panel, said frame being adapted to receive a barrier bag in which said soft product is contained while resting on said base panel below said top panel during evacuation of air therefrom and during said evacuation said side wall providing the sole side closure around said barrier bag.
