What Problems Should Be Paid Attention To In Food Packaging Box Design And Printing?

1. Safety and hygiene of food packaging box:

Food packaging box must ensure the safety of the packaging materials, non-toxic and non-volatile substances, that is to say, packaging materials themselves have stable tissue components. In addition, during the process of packaging process, there will be no chemical reaction with food components and chemical components. Chemical changes will not occur due to the changes of climate and normal environmental factors during storage and transfer.

2. Strength requirements for food packaging box:

Since food can reach consumers only after packing, it must pass the circulation process of stacking, transportation and storage, which requires food packaging to have certain strength and will not be damaged during circulation.

3. Requirements for the permeability of food packaging box:

The barrier requirements of food packaging are determined by the characteristics of food itself, and different food requirements for its packaging barrier characteristics are different. The barrier of food packaging can not enter the food in the packaging by all kinds of bacteria, dust, light, gas and water in the external environment, on the other hand, it is to ensure the moisture, grease, aromatic components, etc. contained in the food, and the essential components of food quality do not penetrate outward, so as to ensure that the packaged food does not deteriorate.

4. Requirements for temperature resistance of food packaging box:

In the process of food processing, most of them are heat treated, some are packaged and treated with high temperature, such as canned food and small cooking food, some are hot filling, such as so many hot drinks, and many foods have a long shelf life. If it reaches or exceeds one year, it is inevitable that the storage process of this kind of food under normal temperature will inevitably pass hot summer, and it should be continuously over 300C. All of these require food The package of the product has certain temperature resistance. With the different food and processing technology, the requirements of temperature resistance are different.

5. Promotional requirements for food packaging box:

Promotion is one of the important functions of food packaging. The promotion requires that food packaging materials should be easy to print, easy to shape, easy to color, light weight and so on. In this respect, plastics undoubtedly have unique advantages.
