Do you know everything about packing

Why do foods need packaging


Previously, the food we ate was grown, raised and processed in a relatively close retail network. Today, our food comes from all over the world.


Packaging has multiplied, and the need for a good environment for transporting and storing food runs through the distribution chain. Without proper design and packaging to ensure that food can be delivered to consumers in the most economical way in the first place, all the efforts in food production and processing will mean nothing.

What functions does the package contain


In recent years, the role of packaging in the food industry has grown rapidly. Technological and commercial innovations have transformed the simple use of packaging materials and containers into an important determinant of logistics efficiency. Nowadays, packaging plays an important role in the most basic protection and preservation of food from three levels.


(1) Primary packaging (the packaging we bring home from the supermarket) must be easy to identify, open (or reseal if necessary) and compatible with the food being packaged.


(2) Secondary packaging (done by the supermarket) is to gather the primary packaged products and divide them into packages of controllable size and weight that are easy to ship, display and sell.


(3) The third package (transport package) is a standard size forming unit load for bulk transport.


Therefore, for packaging to meet these functions, the following conditions must be met:


• Ensure the safety of packaged foods


Maintain the original quality of food


Prevent or minimize mechanical damage to food


• Provides useful information to be noted during the consumption of a food to facilitate the correct identification of the product (e.g. proper cooking method, storage temperature, etc.)


• Easy to move and handle (three layers of packaging, if necessary)


Packaging must also comply with food laws and regulations


Whether the packaging material will affect the food


Packaging materials can preserve the food inside, so that it will not deteriorate during the maintenance period, from external pollution, in the process of transportation and storage is not destroyed. On the other hand, packaging materials that come into direct contact with food must be guaranteed to be themselves harmless to food. The packaging materials for special foods must be carefully chosen with these factors in mind.


Is packaging a waste of materials and energy


Most fresh and processed foods form inedible materials (such as shells, skins, vegetable leaves, animal or fish bones) during the preparation of packaging. As a result, the discarded materials can be used as animal food or for other purposes rather than being thrown away as waste.


Energy is also saved, rather than having to convert inedible substances into edible ones that are passed on to consumers through the distribution and retail chains. Studies by the World Health Organization (WHO) show that food waste in underdeveloped regions of the world can reach 30-50% without food packaging and no more than 2-3% with good packaging.
