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 1. Store sweet corn in the refrigerator. Keep the corn in the husks, and place them in the crisper drawer of your refrigerator. Sweet corn not only goes bad quickly, but it also loses its sweetness over time. For these reasons, use refrigerated corn within two days. Step 2. Freeze corn still on the cobs.
