         10 . The packaged product of  claim 9 , wherein the temperature sensitive product comprises a food product. 
     
     
         11 . The packaged product of  claim 10 , wherein the food product comprises a nutritional composition. 
     
     
         12 . A container assembly comprising:
 a support;   a temperature sensitive product positioned on the support; and   a packaging comprising a temperature barrier layer comprising at least one phase change material, the phase change material is within at least one compartment in the temperature barrier layer.   
     
     
         13 . The container assembly of  claim 12 , wherein the temperature sensitive product comprises a food product. 
     
     
         14 . The container assembly of  claim 13 , wherein the food product comprises a nutritional composition. 
     
     
         15 . The container assembly of  claim 12 , wherein the support comprises component selected from the group consisting of: a pallet, a slip sheet and combinations thereof. 
     
     
         16 . A storage assembly comprising:
 a storage unit;   a temperature sensitive product located within the storage unit; and   a packaging comprising a temperature barrier layer comprising at least one phase change material, the phase change material is within at least one compartment in the temperature barrier layer attached to at least one wall of the storage unit.   
     
     
         17 . The storage assembly of  claim 16 , wherein the temperature sensitive product comprises a food product. 
     
     
         18 . The storage assembly of  claim 17 , wherein the food product comprises a nutritional composition. 
     
     
         19 . The storage assembly of  claim 16 , wherein the storage unit is selected from the group consisting of trailer, refrigerator, freezer, cargo container and combinations thereof. 
     
     
         20 . The storage assembly of  claim 16 , further comprising; a transporter; wherein the storage assembly is attached to the transporter. 
     
     
         21 . The storage assembly of  claim 20 , wherein the temperature sensitive product comprises a food product. 
     
     
         22 . The storage assembly of  claim 21 , wherein the food product comprises a nutritional composition. 
     
     
         23 . The storage assembly of  claim 20 , wherein the transporter is selected from the group consisting of car, truck, semi-truck, airplane, helicopter, boat, train and ship.
