Abstract

This invention relates to an elasticated materials comprising a stiff carrier material that is satisfactorily elasticated with one or more elastic strands with a low load force, due to the use of a specific bonding pattern, with specific bonding areas. The bonding areas are typically separate bonding areas positioned on separate intervals along the length direction of the carrier material, whereby each bonding area comprises one or more separate bonding zones, extending in the width (X) direction.The invention also relates to absorbent articles comprising this elasticated material and processes for making the elasticated material.
