UN PANAL READHERIBLE (10) QUE TIENE UNA ZONA DE SEGURIDAD (20) SOBRE LA CUBIERTA EXTERIOR DEL PAÑAL (12) CON UNA RESISTENCIA MAXIMA INFERIOR A 2750 GRAMOS/PULGADA. EL SISTEMA DE FIJACION DE CINTA ADHESIVA READHERIBLE DEL PAÑAL (10) INCLUYE UNA CINTA FIJACION ADHESIVA (24) QUE INCLUYE UN REFUERZO FLEXIBLE (32) Y UNA CAPA DE ADHESIVO PIEZOSENSIBLE (34) COMBINADA PERMANENTEMENTE CON EL REFUERZO FLEXIBLE (32) Y ADAPTADA PARA SER COLOCADA Y RETIRADA DE LA ZONA DE SEGURIDAD (20) PARA FIJAR Y SOLTAR EL PAÑAL (10). EL ADHESIVO PRESENTA UNA ADHERENCIA DE 180 GRADOS DE LA CINTA (24) A LA ZONA DE SEGURIDAD (20) INFERIOR A LA RESISTENCIA MAXIMA DE LA ZONA DE SEGURIDAD (20). EL ADHESIVO (34) SE SELECCIONA DE MODO QUE SE ENCUENTRE DENTRO DE UNA VENTANA REOLOGICA ESPECIFICA, ES DECIR, QUE TENGA UN DELTA DE TANINO MAXIMO DE 1,5 GRADOS CENTIGRADOS A 2,5 GRADOS CENTIGRADOS A 20 GRADOS CENTIGRADOS, ALCANZADOS A UNA FRECUENCIA SUPERIOR A 500 RAD/SEG. 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 DEG 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)max, of from 1.5 to 2.5 at 20 DEG C., reached at a frequency, or (w)max, of greater than 500 rad/sec.
