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.
Step 2. Place ears of corn in your refrigerator as soon as possible. Leave the husk on, if possible, and let the corn sit in the fridge uncovered. Keep the temperature at or below 40 degrees to reduce the amount of natural sugars in the corn from turning to starch at higher temperatures.
