1. Packaging standards and regulations.
The second is the characteristics of frozen food and its protection conditions.
3. Performance and scope of application of packaging materials.
Fourth, food market positioning and regional conditions of circulation.
The fifth is the influence of the overall structure and material of the packaging on frozen food.
Sixth, reasonable packaging structure design and decoration design.
Seven is the packaging inspection.

Frozen food packaging should have five characteristics:
One is to have high barrier properties to prevent the contact of the product with oxygen and the volatilization of water.
The second is impact resistance and puncture resistance.
The third is low-temperature resistance, and the packaging material will not deform or crack even at a low temperature of -45 °C.
The fourth is oil resistance.
Fifth, it is hygienic, preventing the migration and penetration of toxic and harmful substances into food.
