Food manufacturers package products with consideration for a number of factors: protection, freshness, containment, serving size, marketability, and FDA compliance. Most food maufacturers will outsource their packaging needs to other companies to complete the multi-step process.

Packaging Materials

The most common packaging materials used by food manufacturers are plastic, aluminum and cardboard.

Plastic is the material of choice for most frozen foods, perishable food items, snack foods like chips and pretzels, and a variety of bakery items.

Aluminum is best for beverages like juices, soft drinks and beer, for canned perishable foods, and some baked goods.

Cardboard packaging is used for both frozen and fresh foods along with dry goods like cereals, mixes and rices.

Custom Display

Plastic, cardboard and aluminum are all customizable to display logos, photos, ingredient lists, nutrition facts, and any other information the manufacturer wishes to convey. While some food types allow for flexibilty in packaging material, the material used is usually determined by the nature of the food itself.

Plastic

In bottle form, plastics are used for drinks, marinades, cooking oils, and condiments. Plastic trays are used for fresh or frozen meats and fish.

Aluminum
