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 an 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;
• an entirety of a length of the transverse edges of the front elastic belt is seamed with a certain length of transverse edges of the back elastic belt to define a pair of side seams, wherein the side seams have a seam length LS;
• and
• wherein the back elastic belt divided into multiple zones spanning in the transverse direction and defined by its location from a distal edge to a proximal edge relative to a percentage of the seam length LS, wherein the distal edge is considered 0% and the proximal edge is considered 100%;
• and
• wherein a waist guard portion extends towards the crotch region from a closed base line towards an open edge, wherein the waist guard portion is partially bonded to a remainder of the back elastic belt to define a pocket, wherein an area of the pocket substantially superposes the backsheet, wherein the back elastic belt is divided into 3 zones wherein:
• 0% to a distal edge of the waist guard portion is a back waist zone, the distal edge to a proximal edge of the waist guard portion is a protective zone, and the proximal edge of the waist guard portion to 100% is a buttock zone, wherein elastic members are disposed on each of the back waist zone, the protective zone other than the waist guard portion, and the buttock zone, and a tensile stress of the protective zone is higher than a tensile stress of either the back waist zone or the buttock zone.
