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.
To store your sweet corn, place it in a zip lock bag or in an airtight container in your refrigerator, husked or un-husked, to optimize its longevity. If stored properly it can last up to 7 days. Freezing your sweet corn can be a simple way to enjoy it year round. Simply start by husking your corn and removing any remaining silk from the cob. Blanch your cobs in boiling water for about 4-6minutes. Immediately remove and place in a bowl of ice water to stop the cooking process.
