Package right 



The right containers for frozen foods are of moisture- 

 vapor-resistant material that can be sealed tightly. If 

 foods aren't packaged right, they dry out and lose 

 vitamins. 



Many types of heat-sealed packages are satisfactory. 

 Plastic-coated boxes, and cartons with specially treated 

 liners or covers protect foods well and are easy to handle 

 and store. There are also ready-made bags for frozen 

 foods or you can make bags of any shape or size from 

 specially treated heat-sealing' material by running a warm 

 iron over the folded edges. 



Cover single-thickness cellophane bags with a carton 

 or mesh cloth known as "stockinette." 



Test heat-sealing liners with water to be sure they 



don't leak. After the liner dries, re-seal leaky seams with 

 a warm iron. 



Waxed cups are convenient but the seal is not vapor- 

 proof and food dries out and may darken during a long 

 period of storage. 



Glass jars may be used, but they do not pack so well 

 in the freezer and may break. Foods must be thawed 

 before cooking to remove from jar. Tin cans are satis- 

 factory for fruits, but should not be used for vegetables 

 until further research is done. 



Leave head space. — Food expands as it freezes. 



When packed without liquid, leave about 1/2 inch head 

 space at top of carton or bag for foods that pack tightly. 

 No head space is needed for loosely packed foods such 

 as broccoli or cauliflower.
