Abstract
A package comprising an interior space and an exterior surface may have a plurality of disposable absorbent articles disposed within the interior space of the package. Each of the disposable absorbent articles may have a topsheet; a backsheet; a substantially cellulose free absorbent core located between the topsheet and the backsheet. The absorbent products may exhibit an In-Bag Stack Height of less about 80 mm as measured according to an In-Bag Stack Height Test.
Claims20
An absorbent product comprising:
- a package having height, width and depth dimensions, an interior space and an exterior surface, the package comprising a film;
- a plurality of disposable absorbent articles, which are bi-folded and arranged to form a stack of disposable absorbent articles, wherein the stack of disposable absorbent articles is compressed along a compression axis and disposed within the interior space of the package such that the compression axis of the stack of disposable absorbent articles is oriented substantially along the width dimension of the package, each of the folded disposable absorbent articles comprising a topsheet, a liquid impervious backsheet, a substantially cellulose free absorbent core located between the topsheet and the backsheet, a first waist region, a second waist region, and a crotch region extending longitudinally between the first and second waist regions, and a fastening member-adapted to releasably connect with a landing zone;
- wherein the backsheet comprises a thermoplastic film having an inner facing surface and an outer facing surface;
- wherein the substantially cellulose free absorbent core comprises a nonwoven substrate having first and second surfaces, an absorbent particulate polymer material disposed on the second surface of the nonwoven substrate and a thermoplastic composition applied to the absorbent particulate material, wherein the first surface of the nonwoven substrate faces the inner facing surface of the thermoplastic film;
- wherein more than 60% of the absorbent particulate polymer is disposed in a front half of each of the absorbent articles;
- wherein the absorbent product exhibits an In-Bag Stack Height from 72 mm to 80 mm wherein the In-Bag Stack Height is the width of the package divided by the number of the disposable articles per stack and then multiplied by ten;
- wherein the disposable absorbent articles exhibit a longitudinal bending stiffness of less than 355 N/m upon removal from the package;
- and
- wherein the thermoplastic composition has a softening point in the range between 50° C. and 300° C.
