PRESSURE-SENSITIVE ADHESIVE CLOSURE FOR DISPOSABLE DIAPER |
摘要 |
41626 CAN 9A Pressure-Sensitive Adhesive Closure for Disposable Diaper A pressure-sensitive adhesive closure for a disposable diaper can exhibit high peel resistance both at low and high speeds while its peelability at high speeds is not excessively shocky when it employs a pressuresensitive adhesive of a certain rheology and it has, covering the fastening area, a polyolefin layer having microtopographical features as in Figs. 1-6 of the drawing. As seen in Figs. 1-6, suitable microtopographical features are provided by a large number of closely spaced asperities at least two micrometers in height that have a jagged appearance at 500x. A pressuresensitive adhesive of suitable rheology can be provided by a blend of an AB block copolymer, such as a copolymer of styrene and either isoprene or butadiene, and tackifying resin, preferably a mixture of liquid and solid tackifying resins. |
