An adhesive strip is described which comprises

Controlled adhesion strip

A fastener tab for disposable diapers has improved tactile softness provided by surface morphologies of preselected projection and/or relief dimensions.

Method of manufacturing a soft diaper tape

Soft diaper tape

A release liner providing a release surface which comprises a first olefin polymer film formed having dispersed therein by high shear mixing a release substance which is polyethyleneimine octadecyl carbamide, polyvinyl octadecyl carbamate or a mixture thereof, coextruded or cocast onto a film formed from a second olefin polymer. The release liner has particular utility in diaper tape application.

Release films formed by coextrusion

A refastenable diaper is provided with a securing zone on the diaper outer cover of a peak strength of less than 2750 grams/inch. A refastenable adhesive taping system for the diaper includes an adhesive fastening tape comprising a flexible backing and a layer of pressure-sensitive adhesive permanently combined to said flexible backing and adapted to be applied to and released from the securing zone to fasten and open the diaper. The adhesive exhibits a 180.degree. peel adhesion of the tape to the securing zone that is less than the peak strength of the securing zone. The adhesive is selected to be within a specified rheological window, that is, have a maximum tan delta, or (tan delta).sub.max, of from 1.5 to 2.5 at 20.degree. C., reached at a frequency, or (w).sub.max, of greater than 500 rad/sec.
