Through abstract techniques, the product packaging is more artistic, leaving room for people to imagine. yltpackaging summarizes what aspects must be paid attention to when designing food packaging bags. The use of color: Color plays an important role in the design of food packaging bags. Each color has its own meaning and emotion. It can radiate people’s feelings and arouse people’s psychological resonance. The collocation of color has the function of making the picture vivid, harmonious and unified. Color has a relatively fixed application rule in food packaging design; if this rule is not followed, it will be difficult to achieve people’s psychological recognition and resonance. Complementary color matching and matching of the same color are the most used. Coordinated color matching can effectively enhance product value. Graphics and pattern design: Food can display the characteristics and essence of the product through the graphic design of the packaging. In the design of modern food packaging bags, the most used is to directly reflect the product in the picture. The use of graphics and patterns requires visual balance and conforms to people’s visual habits. The main and secondary performances are reflected in the proportion and position. The overall picture must have a visual focus, so that consumers can see this element first when they are far away, and then attract him to look at other parts of the package. Logo and text design: text occupies a relatively large proportion in the packaging picture. It is the most important way and means to convey product information to consumers. It must give people a clear visual impression. The text in the design of food packaging bags should avoid being complicated and messy, and different types of products require different design styles. The font design of product packaging must be coordinated and consistent with the packaging picture, so that the product packaging can be integrated and visualized.
