Abstract
The invention relates to a system for fastening refastenable garment such as diaper or incontinent garment in which a tape and polymer backing material for the garment are provided such that tape may be removed after refastening to the diaper without tearing of the polymer material. The system of the invention utilizes a polypropylene tape material that is embossed on the outer surface and smooth on the adhesive-carrying surface. The adhesive on the tape is a semihard adhesive that provides high adhesion values to the polymer that nevertheless may be peeled free for removal of the tape and subsequent refastening. The polymer forming the outer backing if the diaper is a relatively thick, embossed polymer sheet. In the refastenable system of the invention the strength and adherence of the tape to the strong, embossed polymer backing sheet is controlled so as to achieve secure fastening with release of the adhesive from the embossed sheet without tearing.
