Aseptic processing is applied to foods that are aseptic and have to be kept in a sterile environment. These foods include liquid eggs, milk and dairy beverages, and other foods that are processed and need to be kept for a long time.

Trays are mainly used for packaging things that can be carried, such as meat, plant seeds, and beverages.

Bags are also a common form of food packaging, most commonly bags of snacks, such as chips and pretzels, and some fruits, such as apples and bananas.

Boxes are the easiest way to transport food. Frozen pizza, cereal, and snack crackers are all foods packaged in boxes.

Cans are also an excellent way to preserve and transport food. Most cans are made of steel or other thin metal, and foods such as canned fruit and eight-pack porridge are packaged using cans.

There are usually four categories of carton type packaging, such as egg cartons, which are mainly egg-shaped and add protection when food is moved. Aseptic cartons also fall into this category, such as milk and juice. Another classification of cartons is the folding carton, which is initially flat and requires assembly when used. The last category is the hill-wall top carton. These cartons usually contain milk or juice and require pinching the top hill wall and then pulling to open.

Flexible packaging is similar to bags. Flexible packaging protects food from the environment, and bagged salads are a common food item in flexible packaging.

Trays are used for mass transportation of products. And wrapping paper is usually used for individual items, effectively preventing food from being contaminated by hands, such as sugar paper.
