Development trend of the hottest tea packaging

The development trend of tea packaging

tea, which has a drinking history of thousands of years, has won more favor today when people pay more and more attention to health preservation. In 2003, the area of tea plantations in China reached 1.19 million hectares, and the total income of tea was 34billion yuan, equivalent to 7.4 times that of 1990. With the expansion of tea consumption market, the packaging of tea also tends to be diversified. The emergence of various packaging technologies has effectively promoted the sustainable and healthy development of China's tea industry

according to different production processes, China divides tea into green tea, black tea, oolong tea, scented tea, pressed tea, white tea and instant tea. Black tea is made by full fermentation, oolong tea by semi fermentation, green tea by non fermentation, scented tea by scenting, white tea by withering, and pressed tea by pressing products. In order to facilitate sales and achieve long-term storage, tea usually needs to be packaged

main packaging forms

at present, there are a wide variety of containers used for tea packaging in the market, including metal cans, lined bags, composite film bags, paper bags, bamboo (wood) boxes, etc. Due to the different physical properties of various packaging materials, such as moisture permeability and air permeability, the effect of preventing tea deterioration is also very different

metal can packaging

metal cans are made of tinned sheet steel. They are square and cylindrical in shape, including single-layer cover and double-layer cover. From the perspective of sealing, there are two types: general tank and sealed tank. Generally, the tank is packed with 5.8pct deoxidizer to remove the oxygen in the package. Sealed cans are mostly used for inflatable and vacuum packaging. The protective property of metal cans to tea is better than that of composite 21. Thermal conductivity: gb/t 3399 ⑴ 982 (1989) experimental method for thermal conductivity of plastics thermal protection plate method film, and its appearance is beautiful and noble

packed in lined bag box

the packaging box is made of plastic film layer or cardboard coated with moisture-proof paint as the packaging material. This kind of packaging not only has the function of composite film bag packaging, but also has the protective, rigid and other properties of carton packaging. If plastic bags are used inside to form small packaging bags, the protective effect is better

composite film bag packaging

at present, more and more tea packaging adopts composite film bag packaging. There are many kinds of composite films for packaging tea, such as moisture-proof cellophane/polyethylene/paper/aluminum foil/polyethylene, biaxially stretched polypropylene/aluminum foil/polyethylene, etc. the composite film has excellent gas resistance, moisture resistance, fragrance retention, odor prevention, etc. The composite film with aluminum foil has better properties, such as excellent shading. The packaging forms of composite film bags are various, including three side sealing shape, self-supporting bag shape, folding shape, etc. In addition, the composite film bag has good printability, which has a unique effect when used for sales packaging design

paper bag packaging

this is a kind of bag packaging with thin filter paper as the material, which is usually called bag brewing tea. When used, it is put into the tea set together with the paper bag. In the early days, tea bags were added with bag threads to facilitate multiple soaking. Considering the requirements of environmental protection, tea bags without bag threads are becoming increasingly popular. The main purpose of using filter paper bag packaging is to improve the leaching rate, and also make full use of the tea powder in the tea factory

bamboo (wood) box

bamboo (wood) box is mostly used as gift packaging. This kind of container is usually finely made, and the surface is printed with beautiful patterns, which has good decoration. Moreover, it is full of traditional Chinese culture and has strong market appeal. Its main drawback is that the sealing effect is poor, so aluminum foil coated bags are often used as inner packaging. The relatively high price is also one of the reasons that hinder its promotion

fresh keeping technology is the key

although tea is a dry food, its storage performance is much better than fresh goods, but it is also a kind of volatile food. If the storage method is slightly improper, it will lose its flavor in a very short period of time. No matter what kind of packaging material is used, it must have the function of moisture-proof, gas insulation and shading

moisture proof

the water content in tea should not exceed 5%, and 3% is the best for long-term storage. Otherwise, the ascorbic acid in tea is easy to decompose, and the color, aroma, taste, etc. of tea will change, especially at higher temperatures, the deterioration speed will be accelerated. Therefore, packaging materials with good moisture-proof performance can be selected for moisture-proof packaging, such as composite films based on aluminum foil or aluminum foil evaporation film, which can be highly moisture-proof. Black tea packaging should pay particular attention to moisture-proof treatment

anti oxidation

the oxygen content in tea packaging must be controlled below 1%. Too much oxygen will lead to oxidation and deterioration of some components in tea. For example, ascorbic acid is easily oxidized to deoxyascorbic acid, and further combines with amino acids to produce pigment reaction, which changes the taste of tea

in terms of packaging technology, vacuum packaging or inflatable packaging can be used to reduce the existence of oxygen. Vacuum packaging is to put tea into a soft film packaging bag with good air tightness, vacuum the bag during packaging, and then seal it. In case of inflatable packaging, nitrogen should be filled while air is extracted. The purpose of nitrogen filled packaging is to protect the stability of the color, aroma and taste of tea and maintain its original quality. Inflatable packaging has strict requirements on materials, mainly in the following aspects: non-toxic and odorless (including the odor of printing ink, solvent and adhesive); Good air tightness and low oxygen permeability; moisture-proof; It has sufficient mechanical strength and puncture resistance; Good heat sealing performance; Good shading performance

shading

because tea contains chlorophyll and other substances, when packaging tea, it must be shaded to prevent the photocatalytic reaction of chlorophyll and other components. In addition, ultraviolet radiation is also an important factor causing the deterioration of tea. Shading packaging technology can be used to solve this kind of problem. Since most plastic films have a light transmittance of 80% - 90%, in order to reduce the transmittance, ultraviolet inhibitors can be added to the packaging materials or the light transmittance can be reduced by printing and coloring. In addition, composite materials based on aluminum foil or vacuum aluminum coating can be used for shading packaging

gas barrier

the fragrance of tea is very easy to lose, so materials with good air tightness must be used for fragrance preservation packaging. In addition, tea is very easy to absorb the odor of the outside world, so that the aroma of tea is infected. Therefore, the peculiar smell produced by packaging materials and packaging technology should be strictly controlled

packaging design highlights characteristics

tea packaging is not only an important means to maintain quality, but also can add value to goods. Highlighting the characteristics of tea in each package is the most fundamental purpose of tea commodity packaging. The ingenious use of colors, patterns, words and other factors can often make tea packaging achieve the effect of silence rather than sound

color design

color is the most attractive one in packaging design. If the color is matched properly, consumers will have a pleasant feeling after seeing it, which can often arouse consumers' desire to buy. The color of the package is restricted by the commodity attribute, and the color itself also has its attribute, so the color should be used carefully, and strive to be less but precise, concise and lively. Whether it is fresh and elegant, gorgeous and moving, or plain and natural, we should not only consider the customs and appreciation habits of consumers, but also consider the different grades, occasions, varieties and characteristics of commodities and use different colors. Design should pay attention to the unity of color and overall style, and cannot use too many colors and lose the main tone. At the same time, similar products should be investigated and studied to learn from each other and design competitive packaging

pattern design

the pattern design of tea packaging can make goods more visualized, vivid and interesting. However, some packaging patterns on the market are old, cumbersome, not very marketable, and lack a sense of the times and personality. Many products tend to highlight nationality in packaging, which is understandable, but it is not just a dragon or a phoenix that can represent traditional culture. It is suggested that modern techniques can be used to deform the traditional pattern, making it more modern and concise, so as to give it new content, new form, and even new life

in addition to hand-painted patterns, photographic pictures can also be used in tea packaging. The objects of photography can include the color and shape of tea itself, elegant tea sets and the color of tea soup when brewing, the natural scenery and local customs of the origin, and so on. For example, West Lake Longjing tea is famous for its green color, fragrance, sweet taste and beautiful shape. It is produced in Shifeng, Longjing, Meijiawu and other places in Hangzhou's West Lake mountain area with undulating peaks and beautiful scenery. If the sales package is accompanied by charming scenery photos of the origin, the attractiveness of tea on the shelf can be greatly improved

text design

the food safety law has clearly stipulated that the text of the qualified tea packaging of the factory products by the production enterprises is also an important part of the design. A package can be without any decoration, but it cannot be without text. The words of tea packaging should be concise and easy to understand, which can fully reflect the attributes of goods

tea is a commodity with strong tradition and nationality. Chinese calligraphy has a long history, and has strong artistry and appreciation. It is certainly the best to properly use calligraphy to reflect the deep bottom rhyme of tea culture. However, on the whole, it should be clear to people at a glance, and avoid using too cursive fonts or too obscure words
