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.
Check the corn after about 6 hours of drying time. The kernels should feel brittle and firm to the touch. Return them to the oven if necessary until they reach this point. Take the trays out of the oven and let them cool to room temperature. Store dried corn in an airtight storage container for up to 6 months.
