         6 . The absorbent article according to  claim 1 , wherein the second glue application area comprises at least a first portion on one side of the longitudinal axis and at least a second portion on the other side of the longitudinal axis. 
     
     
         7 . The absorbent article according to  claim 6 , wherein the first and second portions of the second glue application area extend along the full length of first channel and the second channel. 
     
     
         8 . The absorbent article according to  claim 1 , wherein at least one of the first channel and the second channel comprise less absorbent material than the area between the first channel and the second channel. 
     
     
         9 . The absorbent article according to  claim 1 , wherein the absorbent material of the absorbent core comprises less than 20% of cellulosic fibers, by weight of the absorbent material. 
     
     
         10 . The absorbent article according to  claim 9 , wherein the absorbent material is free of cellulosic fibers. 
     
     
         11 . The absorbent article according to  claim 1 , wherein the first channel and the second channel are substantially free of absorbent material and wherein the first channel and the second channel are surrounded by absorbent material. 
     
     
         12 . The absorbent article according to  claim 1 , wherein a top side and a bottom side of the core wrap are attached to each other through the channels. 
     
     
         13 . The absorbent article according to  claim 1 , wherein the first channel and the second channel are longitudinally extending and each have a length as projected on the longitudinal axis which is at least 25% of the length of the absorbent core. 
     
     
         14 . The absorbent article according to  claim 1 , wherein the first channel and the second channel do not extend to any edge of the absorbent core. 
     
     
         15 . An absorbent article for personal hygiene having a wearer-facing side, a garment-facing side and a longitudinal axis, the article comprising:
 a topsheet on the wearer-facing side;   a backsheet on the garment-facing side;   an absorbent core between the topsheet and the backsheet, the absorbent core comprising:
 an absorbent material comprising a superabsorbent polymer; 
 a core wrap enclosing the absorbent material; 
 a first channel disposed on one side of the longitudinal axis and a second channel disposed on the other side of the longitudinal axis, and an area between the first channel and the second channel; 
 a first glue disposed in a first glue application area and having a first glue application pattern, wherein the first glue application area is at least partially disposed in the area between the channels; and 
 a second glue disposed in a second glue application area and a second glue application pattern, wherein the second glue application area is at least partially outside the area between the channels; 
 wherein the first glue application pattern differs from the second glue application pattern; and 
 wherein the first glue is continuous. 
   
     
     
         16 . The absorbent article according to  claim 15 , wherein the first channel and the second channel comprise less absorbent material than the area between the first channel and the second channel. 
     
     
         17 . The absorbent article according to  claim 15 , wherein a top side and a bottom side of the core wrap are attached to each other through at least one of the first channel and the second channel.
