Pouch

Abstract

A pouch adapted to accommodate a hygienic article is described. The pouch comprises a body including a longitudinal axis, a transverse axis, and an intended opening axis substantially parallel to the longitudinal axis. The pouch including an oriented, multilayer film laminate. The film laminate includes at least one outer layer comprising 35% to 65% alkaline earth carbonate, the outer layer having a thermal conductivity; and a core layer comprising a lower thermal conductivity that is a lower thermal conductivity than the outer layer. The core layer is in contact with at least one layer of said outer layer. The film laminate is made by coextrusion of the outer layer and the core layer, and subsequent orientation. The film laminate further includes a CD tensile strength and a MD tensile strength wherein a MD:CD tensile strength ratio is at least about 6:1.

1 . A pouch adapted to accommodate a hygienic article comprising: 
 a body comprising having a longitudinal axis, a transverse axis, and an intended opening axis substantially parallel to the longitudinal axis;    said pouch comprised of an oriented, multilayer film laminate;    said film laminate comprising at least one outer layer comprising 35% to 65% alkaline earth carbonate; said outer layer having a thermal conductivity; and    a core layer comprising a lower thermal conductivity that is lower than said outer layer;    said core layer being in contact with at least one layer of said outer layer;    said film laminate being made by coextrusion of said outer layer and said core layer, and subsequent orientation; wherein    said film laminate further comprises a CD tensile strength and a MD tensile strength wherein a MD:CD tensile strength ratio is at least about 6:1.    
   
   
       2 . The pouch according to  claim 1  wherein said alkaline earth carbonate is CaCO 3 .  
   
   
       3 . The pouch according to  claim 2  wherein said outer layer comprises from about 40% to about 60% of CaCO 3 .  
   
   
       4 . The pouch according to  claim 1  wherein the multiplayer laminate comprises at least one outer layer comprising polyethylene and CaCO 3  and at least one core layer comprising polypropylene.  
   
   
       5 . The pouch according to  claim 1  wherein said core layer comprises a copolymer of polypropylene and polyethylene.  
   
   
       6 . The pouch of  claim 1  wherein said core layer comprises a copolymer of 90% polypropylene and 10% polyethylene.  
   
   
       7 . The pouch according to  claim 1  wherein the outer layer comprises LDPE.  
   
   
       8 . The pouch according to  claim 1  wherein the outer layer comprises LLDPE.  
   
   
       9 . The pouch of  claim 1  wherein the seal strength is greater than the tensile strength.
