A laminate structure that is formed from a first substrate, a second substrate, and discrete regions of particles sandwiched therebetween is provided. In particular, the first and second substrates are bonded together at certain portions such that bonded portions and unbonded portions are formed. The unbonded portions form pockets that contain the particles. The pockets have a length-to-width ratio of greater than about 2. The resulting laminate structure of the present invention can have inner regions that delaminate upon the application of a certain force (e.g., swelling of superabsorbent particles), as well as perimeter regions that do not substantially delaminate upon the application of the same force.
L'invention concerne une structure laminée formée d'un premier substrat, d'un second substrat, et de régions discrètes contenant des particules entre les deux. En particulier, le premier et le second substrat sont liés ensemble à certains endroits de manière à former des parties reliées et des parties non reliées. Les parties non reliées forment des poches contenant les particules. Les poches présentent un rapport longueur-largeur supérieur à 2. La structure laminée obtenue peut comprendre des régions internes se décollant avec l'application d'une certaine force (par exemple, le gonflement de particules superabsorbantes), ainsi que des régions périphériques ne se décollant sensiblement pas avec l'application de la même force.
