<p>An absorbent product has an elongate matted strip of absorbent material, including super absorber, within an enveloping container. This has a double skin bottom and a single, folded top skin and is heat sealed around its periphery to contain the absorbent material. The top skin has an elongate, double Z fold along its length. As the container absorbs moisture it expands from a flat form to a round shape. The super absorber causes tension in the skins of the container as it reaches its absorption limit which tears the self-adhesive strips. The folds unfold and the round shape slumps to expose inner webs. An indicator in the form off the words“FULL-CHANGE”printed in a bright colour repeatedly along the inner webs is provided to alert maintenance staff of the need to change filled absorbent products for fresh one.</p> |
