Have you every opened a carton of ice cream and what you see is the dreaded layer of freezer burn? That happens due to the product being stored at off temperatures (getting warmer and then cooler) or from the product being shelved too long.
Frozen food packaging has a job to preserve food from the time it is prepared to the time it is eaten — all the way throughout the product’s journey. The packaging helps to maintain original color, flavor and texture and generally more of their nutrients than foods preserved by other methods. Fruits & vegetables, meat and seafood, and frozen desserts & ice cream and baked goods are packaged in bags, boxes, tubs & cups, trays, wrappers and pouches. And each pack type must be able to handle the trip.
