Tea packaging is the key to ensure the quality of tea in the fields of purchase, sale, storage and circulation. A delicate and unique tea packaging can not only give people beautiful enjoyment, but also directly stimulate consumers' desire to buy in today's supermarkets and changing sales methods, thus achieving the purpose of promoting sales and playing the role of silent salesman. Good tea packaging has collection value, and can also be used as reusable packaging, which not only saves resources, but also promotes tea culture. A good tea packaging design must have a good foundation, which is the most essential thing of packaging, that is, how to keep the quality of tea from deteriorating. Only by fully understanding the characteristics of tea and the factors that lead to tea deterioration can we choose suitable materials and use them reasonably according to these characteristics to achieve perfection. Especially pure natural and pollution-free green food, it is necessary to strengthen environmental awareness and meet people's demand for returning to nature. The characteristics of tea are determined by the physical and chemical composition and quality of tea, such as hygroscopicity, oxidation, adsorption, fragility and variability. Therefore, when designing tea packaging, we should consider using suitable materials for packaging according to the above characteristics. It is necessary to choose a composite material with good moisture resistance, oxygen resistance, light resistance, odor resistance and certain tensile strength. According to investigation and study, polyester/aluminum foil/polyethylene composite is better used in the market at present, followed by stretched polypropylene/aluminum foil/polyethylene composite. These are often called aluminum platinum summer films, which are small daily tea bags. Now there is a new kind of packaging box, which is made of paper. The upper and lower lids of cans are made of metal, and the cans are offset paper/paper aluminum foil/polyethylene. The fresh-keeping effect is very strong, and it is much lighter than metal cans, and the design means are richer and more beautiful, giving designers more room to play. Tea packaging can generally be divided into two categories, namely, large packaging and small packaging. T-type large packaging is also called transport packaging. Mainly for the convenience of transportation, loading and unloading and storage. Generally, wooden cases, corrugated boxes, iron drums or tin drums are used. Small packaging, also known as retail packaging and sales packaging, can not only protect the quality of tea, but also have certain ornamental value, which is convenient for publicity, display, exhibition and carrying. There are many kinds of small packaging, which can be divided into hard packaging, semi-hard packaging and soft packaging according to different materials. For example, hard packaging includes tin cans, tin cans, porcelain bottles, glass bottles, craft wooden boxes, bamboo boxes, craft gold boxes and so on. Semi-rigid packaging has various cartons; Soft packaging includes paper bags, plastic food bags and various summer bags. The design can design suitable materials according to different needs. When designing tea packaging, the first thing to consider is its material and structure. Whether the packaging material is suitable or not directly affects the quality of goods, which is also determined by the attributes of tea, a special commodity. Therefore, it is generally easy to choose materials with precise structure and easy opening to make tea packaging. With the development of packaging industry and the combination of modern high technology, many new types of packaging have appeared. There are also many novel and unique tea packaging in the market, but some packages seem to be high-grade, but they tend to be over-packaged, and some are divorced from the attributes of commodities and blindly pursue a gorgeous decoration and floating colors, which is inconsistent with the quality of tea itself. For example, there is a kind of tea packaging with gold-plated plastic carving on the market. From the packaging, there is no information to be conveyed by any commodity, which gives people the impression that it is handicrafts, not tea.
