The invention refers to an anatomic absorbent which contrary to similar products exhibits dynamic and anatomic action, accompanying the movement of the body of the user and providing increased protection against leakage. The absorbent of the invention comprises an absorbent substrate (3) sandwiched between a permeable and an impermeable layer (1, 2) which are sealed to each other at least at the ends of the absorbent. On each side, at least along a part of its length, there is provided between the edges of said layers (1, 2) a strip (6) of heat-shrinking material in the contracted state, so that each side takes the form of a raised flap (4 and 5). Said layers are bonded to the strips (6) at a plurality of regions interspaced along the lengths of the strips, there being no continuous bond between the layers and those parts of the flaps which are provided with the strips.

A process is provided for producing a novel two layered or three-layered film of polyethylene and ethylene vinyl acetate copolymer which is heat shrinkable, and after heat shrinking, is elastic and glueable. The process involves uniaxially stretching under controlled, relatively low temperature conditions.

A disposable diaper comprising an absorbent core disposed between a liquid-impermeable backing sheet and a liquid-permeable facing sheet and having means for closing and fastening the diaper around the waist which are independent from means for sealing the diaper around the thighs of the wearer. The diaper employs two regions of adhesive for this purpose. The first said region is preferably located at the upper end of the diaper and comprises two adhesive areas at or near the corners of the diaper. The second adhesive region is located at the other end of the diaper and comprises two adhesive areas which are located in the side margins of the diaper and are spaced away from the corners at said other end. There are slits between the corners of the diaper and the adhesive areas of the second adhesive region. These slits extend inwardly from the side margins of the diaper toward its center.
