It is sometimes convenient to categorize packages by layer or function: primary, secondary, etc. 1  Primary packaging is the material that first envelops the product and holds it. 2  Secondary packaging is outside the primary packaging, and may be used to prevent pilferage or to group primary packages together.
Does Corn Need To Be Refrigerated? Corn does not typically need to be refrigerated in order for it to be safe to eat. You will want to be aware of the fact that the longer you keep your corn in the refrigerator, the more flavor and vitamins you will lose, so it will not have quite as much nutritional value or taste to it.
Cornstarch should be kept covered in a cool dark place (the pantry) away from moisture. The best way to store it is in its original container with the lid re-sealed. As long as it remains dry, it will remain safe to use since the shelf life of cornstarch is really indefinite. Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste.
