1. The design of theme characters in packaging is generally used for commodity names, brand names, brand words, etc., which is the expression of commodity attributes. The design of theme words should be prominent, and sometimes the theme words are directly designed as trademarks, such as Coca-Cola, in which English theme words are trademarks; Sometimes the theme words are also used side by side with trademarks to form a harmonious combination of commodity images. Generally, the design of theme text is more prominent and eye-catching to facilitate consumers' identification and purchase.

2. The readability of the explanatory text is very important, and it should be easy to understand, brief and highlight the theme, and it is not necessary to be lyrical and exaggerated like the copywriting language; However, we should also pay attention to the selection of fonts, and combine the attributes of packaging with suitable fonts, and use new fonts such as calligraphy fonts to make the explanatory text rich in changes. The instructions on the package should not be too much and too complicated. At the same time, we can't ignore the reading rate of human eyes. If consumers want to see and understand all the text content clearly, they should handle all the text content in sections according to the primary and secondary relations. In addition, it is necessary to consider the language according to different sales regions, and the language types of other sales regions can be added, but Chinese characters are still the main ones, except for foreign brands.

3. In order to strengthen the promotion, sometimes there will be some advertising words in the packaging, which are promotional words used to publicize the characteristics of the contents of the goods. Generally, the design of advertising language should be catchy, concise and lively. Compared with other types of words, the content and font design of words are more flexible and diverse. Generally, you can choose varied fonts according to your needs, or even directly use hard pen handwriting to show a natural and cordial feeling and narrow the distance between goods and consumers. Advertising language should be arranged on the main display surface.
