If the facts before the supply of food packaging are viewed, then their range of containers used for transportation products initially has now taken a back seat. When considering the type of delivery device used in the past, the main focus was standing from the standpoint of the manufacturer. As a matter of fact, until the end of the 19th century, generally all shipping materials processing techniques used are easy to transport their goods to market. Those containers made of clay, cork, or wood. 

Then in the 20th century, there was a shift drastically in the materials used for food packaging because most of them are made of glass, metal, and paper. Furthermore, another evolution followed as PETE (Polyethylene Terephthalate) material coming to the market. The benefit is that polyethylene can be easily stamped or molded into any imaginable shape.

Food packaging is important in preserving food during the entire distribution chain. Nevertheless, in recent years, the concept of packaged foods and techniques have increased the shelf life of many foods. Accordingly, these measures have improved the quality, safety, and sustainability of the market. 

Some basic functions of food packaging are:

Protection Barrier:

Ideal food packaging is used to protect the barrier from moisture, oxygen, dust, etc. Permeation is a critical factor when it comes to design. Food packaging may include oxygen absorbers, desiccants to extend product shelf life. 

Physical Protection:

This may require compression, shock, vibration, and temperature when enclosed in a single package.

Grouping:

Some minor items are grouped together in one package for efficient handling. Powder, granular or liquid materials need containment.
