REFASTENABLE ADHESIVE FASTENING SYSTEMS FOR DISPOSABLE ABSORBENT ARTICLES

摘要

Disposable absorbent articles such as baby diapers or adult incontinent briefs p rovided with a refastenable adhesive fastening system. The adhesive fastening system preferably comprises a pair of t ape tabs each having an adhesive surface which during use is adhered to a landing member having an adherence surface which may comprise only the backsheet that has no reinforcement for strength against tearing or may comprise a reinforced backshee t. The invention improves bond security while at the same time making the fastening system more easy to remove without tearing by car eful optimization of the properties of the adhesive, the tape tab, and the landing member. In particular, it has been found that the adhesive fastening system should have a Standard Shear Hang Time of greater than about 1000 minutes per square inch. The surface characteristics, toughness, and elasticity modulus of the landing member is optimized while the adhesive agressiveness (qui ck-slick) of the adhesive is optimized with preferred low coating weights of the adhesive and low calculated caliper for the landing member so as to provide an adhesive fastening system that bonds easily, holds securely and is refastenable.
