Packaging-packaging design has the cultural characteristics of the times and nationality. The formation of a nation will go through a long and tortuous historical development process. At different stages of this process, national culture will show different characteristics of the times. As long as we realize the inheritance and development of packaging design culture, there will be packaging design culture in the times. This is because the packaging design culture is first of all a historical development process, the aggregation and inheritance of the design culture of our nation in various times, the material society based on the reality of this era, the unity of the accumulation and continuous sublation of traditional design culture, and the unity of historicity and reality. The modernity of packaging design culture is mainly reflected in the spiritual and material aspects of packaging design culture. Design keeps up with the times and focuses on creativity. Today, with the rapid development of economic globalization and science and technology, the social form has undergone fundamental changes, especially the widespread dissemination of information, the increasingly fierce concepts, the diversification of social structure, values and aesthetic concepts, the frequent exchanges between people, the increasing demands of society and people, and the alienation of industrial civilization have brought about energy, environment and ecological crises. In the face of all this, whether we can adapt to it and use it to make packaging design a product of the times has become an important task for designers today. The nationality of packaging design involves the spread of culture. Due to the constraints of different natural and social conditions, every nation in the world has formed its own language, habits, morality, thinking, values and aesthetic concepts that are different from other nations, so it is inevitable to form a unique national culture. The nationality of packaging design is mainly manifested in the conceptual level of the cultural structure of packaging design, which reflects the psychology of the whole nation. Different nations and different environments have different cultural concepts, which are directly or indirectly expressed in design activities and works. For example, the scientific, logical and rigorous modeling style of German design, the novelty, dexterity, lightness and exquisiteness of Japanese design, and the elegance and romantic artistic conception of Italian design are all born in the cultural concept atmosphere of different nationalities. Another example is the implication of China's fluent and complete packaging design style and the integrity and symmetry in form, which is also the reflection of our people's introverted psychological characteristics and gentle and peaceful social consciousness. Culture affects consciousness, and consciousness determines thought. Under the influence of different cultures, people's design concepts, ways of thinking and practical achievements are branded with the national brand. Therefore, the humanity of packaging design lies in the nationality, the eternity lies in the times, and the universality is full of particularity, which is the dialectical and unified cultural view of packaging design. China is a big country of tea production and export in the world, with rich varieties of tea and vast producing areas. Tea industry plays an important role in China's national economy. China's tea has always enjoyed a high reputation in the world because of its good quality. However, the backward packaging has lowered the grade of China's tea, which has led to the continuous downturn in the international market position of China's tea. In the eyes of many foreigners, China tea is synonymous with cheap tea. It has always been the aim of China International Tea Packaging Design Competition to explore and cultivate talents for tea packaging design, promote the process of upgrading tea product packaging and improve the international competitiveness of "China Tea". Last year, the first tea packaging design competition held during the Tea Expo won wide acclaim both inside and outside the industry, which further improved the design level of tea packaging in China. The Organizing Committee of the Tea Expo initiated the second tea packaging design competition, collecting the packaging of "China Tea Gift" and Mid-Autumn Festival gift tea, and collecting special packaging according to the different characteristics of tea. The winning works will be grandly exhibited in China International Trade Center during the China International Tea Expo, and the selected works will be included in the China Tea Packaging Collection. In order to reduce the pressure of economic growth on resource supply, the concept of "green packaging" was introduced in this tea packaging design competition. Participants are advised to choose natural, environmentally-friendly and pollution-free materials, and refuse over-packaging on the basis of enhancing international competitiveness.
