1. Preservation principle: The primary task of food packaging is to keep the freshness and quality of food. Packaging design should consider preventing air, light, moisture and odor from entering, adopting appropriate materials and technologies, extending the shelf life of food, and ensuring that food is kept in the best condition during transportation, storage and sales.
2. Safety principle: Food packaging must meet health and safety standards to protect consumers' health. Packaging materials should be strictly screened to ensure that they will not have harmful effects on food. In addition, packaging design should avoid using materials that may release toxic substances to ensure the compatibility of packaging with food.
3. Marketing principle: packaging design should attract target consumer groups and convey the brand image and value of products. By designing unique and attractive packaging appearance, products stand out from supermarket shelves and arouse consumers' interest. The selection of colors, patterns, fonts and other elements should conform to the taste and culture of the target market and enhance the market competitiveness of products.
Considering the above three principles comprehensively, we can design practical and beautiful food packaging, meet the needs of consumers and ensure the quality and safety of products.
