Abstract
The present invention relates to a liquid container containing a plurality of enclosed cells formed between at least a first layer and a second layer of polymeric material. Each enclosed cell contains essentially less than about 2 fluid ounces of an aqueous-based solid or liquid. Preferably, each enclosed cell contains less than about 1 fluid ounce of an aqueous-based solid or liquid. In a further aspect, the first layer and second layer of polymeric materials are perforated to allow separation of an individual enclosed cell from the remainder of the plurality of enclosed cells.
