1、 Protect food and extend its shelf life
In the whole circulation process, food should be handled, loaded and
unloaded, transported and stored, which is easy to cause damage to the
appearance quality of food. After the food is packaged inside and outside, it
can avoid extrusion, impact, vibration, temperature difference and other
phenomena, and protect the food from damage.
In addition, the food produced has certain nutrients and moisture, which
provides the basic conditions for the propagation of bacteria in the air. The
packaging can separate the goods from oxygen, steam, stains, etc. to prevent
food deterioration and extend the shelf life of food.
Vacuum packaging can prevent food from being directly exposed to sunlight
and light, thus avoiding food oxidation, discoloration and taste change.
Anti leakage is also a necessary factor in packaging design. Some packages
include desiccants or deoxidizers to extend the shelf life.
2、 Space saving and convenient circulation
Some foods need to be packaged separately to better circulate in the
market. For example, for objects such as powders and granules, and for liquids
such as drinks and drinks, packaging is both a container and a circulation tool.
The appearance of packaging has facilitated their circulation and further
promoted the expansion of the scale of such products.
In addition, some food with local characteristics can only flow to other
places after packaging.
3、 Conveying information
The label in the package will convey the basic information of the product
to consumers, such as the production date, ingredients, production site, shelf
life, etc., and also tell consumers how to use the product and what precautions
should be taken. The label generated by the package is equivalent to a repeated
broadcast mouth, which avoids repeated publicity by the manufacturer and helps
consumers quickly understand the product.
4、 Improve product competitiveness
When design is paid more and more attention, packaging is endowed with
marketing value. In modern society, the quality of a design will directly affect
consumers' desire to buy. Good packaging can capture the psychological needs of
consumers through design, attract consumers, and enable them to buy. In
addition, packaging can also help products establish brand and form brand
effect.
