         9 . The container of  claim 8 , wherein the heat seal primer facilitates sealing of the barrier layer along the first end margin to the support layer along the second end margin and facilitates sealing of the barrier layer along the bottom margin to the bottom wall. 
     
     
         10 . The container of  claim 1 , wherein the barrier layer has a melting point of over 225 degrees Celsius. 
     
     
         11 . A sidewall blank for at least partially forming a container for holding one or more products, the sidewall blank comprising:
 a support layer; and   a barrier layer comprising polyethylene terephthalate;   wherein a first end margin of the sidewall blank and a second end margin of the sidewall blank are for being at least partially attached to one another in an overlapping relationship to form a seam when the container is formed from the sidewall blank.   
     
     
         12 . The sidewall blank of  claim 11 , wherein the barrier layer extending along the first end margin is for being fused to the second end margin to form a seal along the seam when the container is formed from the sidewall blank. 
     
     
         13 . The sidewall blank of  claim 12 , wherein a heat seal primer is included at least along the first end margin for facilitating sealing of the barrier layer along the first end margin to the second end margin when the container is formed from the sidewall blank. 
     
     
         14 . The sidewall blank of  claim 11 , wherein a heat seal primer is included at least along the first end margin for facilitating sealing of the first end margin to the second end margin when the container is formed from the sidewall blank. 
     
     
         15 . The sidewall blank of  claim 14 , wherein the heat seal primer is printed on the barrier layer along at least the first end margin. 
     
     
         16 . The sidewall blank of  claim 14 , wherein the heat seal primer is for facilitating sealing of the barrier layer along the first end margin to the support layer along the second end margin. 
     
     
         17 . In combination, the sidewall blank of  claim 11  and a bottom blank for forming the container, wherein the bottom blank is for at least partially forming a bottom wall when the container is formed from the sidewall blank and the bottom blank, and wherein a bottom margin of the sidewall blank and a portion of the bottom blank are for being arranged in an overlapping relationship along a bottom seam of the container formed from the sidewall blank and the bottom blank. 
     
     
         18 . The combination of  claim 17 , wherein a heat seal primer is included at least along the first end margin and the bottom margin of the sidewall blank to facilitate sealing of the first end margin to the second end margin of the sidewall blank when the container is formed from the sidewall blank and the bottom blank and to facilitate sealing of the bottom margin of the sidewall blank to the bottom blank when the container is formed from the sidewall blank and the bottom blank. 
     
     
         19 . The combination of  claim 18 , wherein the heat seal primer is for facilitating sealing of the barrier layer along the first end margin of the sidewall blank to the support layer along the second end margin of the sidewall blank when the container is formed from the sidewall blank and the bottom blank and is for facilitating sealing of the barrier layer along the bottom margin of the sidewall blank to the bottom blank when the container is formed from the sidewall blank and the bottom blank. 
     
     
         20 . The sidewall blank of  claim 11 , wherein the barrier layer has a melting point of over 225 degrees Celsius. 
     
     
         21 . A method of forming a container, the method comprising;
 obtaining a sidewall blank, the sidewall blank comprising a support layer and a barrier layer, wherein the barrier layer comprises polyethylene terephthalate;   forming the sidewall blank into a sidewall of the container so that the sidewall extends at least partially around an interior of the container; and   forming a seam of the sidewall comprising attaching a first end margin and a second end margin of the sidewall to one another in an overlapping relationship.   
     
     
         22 . The method of  claim 21 , wherein the forming the seam of the sidewall comprises fusing the barrier layer extending along the first end margin to the second end margin to form a seal along the seam, and wherein a heat seal primer included at least along the first end margin facilitates sealing of the barrier layer along the first end margin to the second end margin. 
     
     
         23 . The method of  claim 21 , wherein a heat seal primer is included at least along the first end margin and the heat seal primer facilitates sealing of the first end margin to the second end margin. 
     
     
         24 . The method of  claim 23 , further comprising obtaining a bottom blank, and forming the bottom blank into a bottom wall of the container, comprising arranging a bottom margin of the sidewall blank and a portion of the bottom blank in an overlapping relationship along a bottom seam of the container. 
     
     
         25 . The method of  claim 21 , wherein the barrier layer has a melting point of over 225 degrees Celsius.
