What are the main functions of food packaging?

There is more to creating food packages than meets the eye. Here are a few of the most important functions:

Protection from Biological Agents: As well as protecting food from rats, insects, germs, bacteria, and other biological factors, food packaging also protects the food from spoilage or contamination.

Food Preservation: Properly packaged food has a longer shelf life because air and moisture are not allowed to reach food items. Open food items can rot within hours when exposed to air and moisture.

Better Usage: The packaging of food also makes it easier to store and use products, including milk cartons and sliced food items provided in cans.

Information:Every food item we buy is packaged with important information, such as the brand name, expiration date, and ingredients.

What types of food packaging are there?

There are several types of food packaging, including:

Trays: The containers have a flat shape with high sides to prevent the contents from falling out. They’re used for storing meat, seeds, fish, and drink cans.

Aseptic Packages: In aseptic cartons, food products and beverages are packaged in sterilized packaging that does not require refrigeration, such as whole liquid eggs, soup, milk, and other dairy products.

Boxes: Cereals, frozen foods, pizzas, fast food, and many other items are packed in boxes.

Bags: Snack crackers, chips, and packed fruits are commonly bagged (put into bags).

Cartons and Coated Paper: Egg cartons are the most recognizable form of food carton, while aseptic cartons and coated paper are typically used to carry liquid items such as milk.

Cans: Often used for beverages or canned food, cans are long-lasting and versatile. They are made from thin metal containers coated in tin to prevent corrosion.

Flexible Packaging: Bagged salad is an example of a product packaged in flexible packaging, such as plastic sheets, foil, or paper.

What are the different types of food packaging machines?

The scale of modern food processing has reached a point where hand packing every food product is no longer possible. Instead, food packaging machine does this job for us.

Case Packing Machines

Food can be packed into trays, cases, baskets, or crates using flexible packaging robots. Defective products can also be rejected using case packing systems.

Pick and Place Machines

They are commonly used to handle chocolates, snack crackers, and similar food products, which are typically picked up from one place and placed in another.


The Smartline automation solution reduces labor costs while speeding up the workflow of your food packaging line.

In addition to being very low-cost, it can load products, cases, and flow wrappers.

Cutting Machines

Innovative cutting solutions, such as food cutting robots, can create precise cutting shapes on food items. Cutting machines are used to slice bread or other food items into smaller pieces.


Generally, cartoning machines are used to make folding cartons and pack food into them. Folding cartons are generally flat cardboard pieces, and cartoners transform them into their final shape.

Packaging Machines

Different types of packaging are available, including blister, skin, and vacuum packaging.

In medicine, blister packs are used, while vacuum bags are used for smaller quantities.

Checkweighing Machines

An item is rejected if the weight of the final packed food item is incorrect, as they are installed at the end of a food packaging line.

Form, Fill, and Seal Machines

In form, fill, and seal machines, food items are filled into pouches or sachets and then sealed. Milk pouches, for example, are made using these machines.

Autocoding Machines

Using autocoding machines, labels are created and installed on food packets. These labels contain details such as manufacturing date, weight, and codes.
