The main goal of food packaging is to secure the content and prevent any form of leakage or breakage. Food packaging also helps to protect the contents from germs, heat and moisture. Besides, it makes the process of distribution easier. 


Listed below are a few benefits of effective food packaging:


Protection and preservation: Food packaging shields food from three major types of external influences.

 Chemical protection is against compositional changes that might be caused due to exposure to gases, moisture or light.
 Biological protection is against micro-organisms, insects, and rodents.
 Physical protection offers a barrier against mechanical damage during distribution.


Reduction of food wastage: Packaging food helps to reduce food wastage by extending shelf-life and preventing leakage during transportation and distribution.


Marketing and product information: Packaging also provides an effective way to advertise the product and include necessary product information for the benefit of consumers.

Convenience: Efficient packaging offers ease of access, handling and disposal.

Tamper indication: Certain special packaging features help to reduce the risk of tampering and adulteration.


Broadly, food packaging can be classified into the following two types:

Retail containers: Retail containers include sachets, glass bottles, cans, over wraps, etc. These are not only used to protect the food but also provide information to consumers. The packaging also helps to advertise products for retail sale.


Shipping containers: These are basically intended to protect the food during the process of distribution and transport. They include sacks, containers, barrels, crates and foil bags.


It is essential to choose the right packaging material to ensure that the quality and freshness of the product is maintained. Some of the materials that are widely used for packaging food and beverages include the following:

Glass: Glass has a long history of being used as a food packaging material, especially liquids. Glass packaging offers an effective barrier against gases and water vapour, due to its impermeable nature. It is used in the production of jars and bottles that can be pasteurized at high temperatures. However, the disadvantage with glass packaging is the fact that insensitive handling may lead to breakage and transportation cost may escalate due to the weight of glass.


Metals: Metals are used in the production of metallic trays, foils, bags and cans. Metals have good barrier properties but they need to be sterilized before being used for packaging. An advantage with metal packaging is that they can be used for frozen and heated meals too. The disadvantage is the high cost involved in this form of packaging.


Cardboard: These can conveniently be used to package dry food like sugar, salt, flour and more. They are light but are permeable to water and air. Besides, this form of packaging has a very low impact on the environment due to the sustainable property of paper.


Plastic: Plastic can either be synthetic or biodegradable. Synthetic plastic packaging is characterized by low production cost, is lightweight and offers good barrier properties.


Laminates: This form of food packaging consists of thin layers of different materials like metallic plastic and paper. The advantage with laminate packaging is that they are airtight and this increases the shelf-life of products.


Food packaging materials should be of superior quality and comply with food safety standards. The packaging should be designed in a manner to provide utmost protection to the content in every way possible.


Some of the methods that are commonly used to ensure successful packaging are:

 Packaging migration testing
 Food contact testing
 Colour bleeding
Leak testing and more


A wide variety of testing equipment is available that help businesses maintain quality standards. With the use of the right equipment, you can get accurate results without any damage to the product.
