1. A container useful to transport a liquid comprising:
- a spiral-wound wall having an exterior surface, at least one open end, an interior surface wherein the interior surface defines a portion of a boundary of a cavity;
a super-absorbent lining adhered to the interior surface in a sufficient amount to convert the liquid into a gel-like state when the liquid comes in contact therewith;
a closure lid impermeable to fluids and frictionally engaged with the container for closing the open end.

Abstract
The present invention relates to a packaging unit designed to absorb and/or adsorb liquid that is being transported or was spilled or was released. The packaging unit has at least one sealing multi-layer comprising a first water soluble film and an absorbent/adsorbent material. When the liquid contacts the water soluble film, the liquid passes through the water-soluble film. When the liquid contacts the absorbent/adsorbent material, the absorbent/adsorbent material immobilizes the liquid material. This immobilization prevents the liquid from escaping from the packaging container.
