Pant-type absorbent article and manufacturing method thereof

An absorbent article having a longitudinal direction and a transverse direction comprising a front elastic belt, a back elastic belt, a crotch region, a waist opening, and a pair of leg openings;

• the crotch region extending longitudinally between the front elastic belt and the back elastic belt;
• the absorbent article comprising an absorbent main body extending the entire longitudinal dimension of the crotch region and further extending partly into each of the front elastic belt and the back elastic belt, the absorbent main body comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent material region sandwiched therebetween;
• the entirety of the length of the transverse edges of the front elastic belt is seamed with a certain length of the transverse edges of the back elastic belt to define a pair of side seams, wherein the side seams have a seam length LS, the seam length LS is at least 110 mm;
• the back elastic belt divided into multiple zones spanning in the transverse direction and defined by its location from the distal edge to the proximal edge relative to the percentage of the seam length LS wherein the distal edge is considered 0% and the proximal edge is considered 100% wherein a waist guard portion is disposed such that the complete waist guard portion is provided within a location of from about 5% to about 60% of LS, the waist guard portion extending towards the crotch region from a closed base line towards an open edge, wherein the waist guard portion is partially bonded to the remainder of the back elastic belt to define a pocket, wherein the area of the pocket substantially superposes the backsheet;
• the waist guard portion comprising a waist guard elastic portion having a longitudinal dimension of no greater than about 50 mm, wherein the remainder of the back elastic belt superposing the waist guard elastic portion is defined a correlated portion, wherein the tensile stress of the waist guard elastic portion is higher than that of the correlated portion.
