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.
Peel the husk completely off, crack off the knob at the bottom, and boil in water for no more than three minutes. Fresh, sweet corn just needs to be heated up. Oh, and smothered in gobs of butter and a dash of salt. Thatâs how heâll dish it out at a family gathering come July 4th.
