Abstract
A tampon having an absorbent structure and an apertured film cover thermally bonded to the absorbent structure is disclosed. The cover is bonded to the absorbent structure through a plurality of discrete spots arranged about the surface of the absorbent structure to provide a cumulative cover-to-absorbent bond. The cumulative cover-to-absorbent bond has a shear strength of at least about 3 N. The plurality of discrete thermally-bonded spots define a bonded area and the bonded spots and the unbonded portions between the spots define a bond region. Preferably, the bonded area covers about 5% to about 30% of the bond region. In addition, a sealing element for a sealing roller is disclosed. The sealing element is profiled with a sealing pattern defined by sealing knobs arranged at distances to each other that project from a base of the sealing element. Each sealing knob has a perimeter shaped to eliminate aggressive edges.
