Packaging materials of tea&beverage in China
On the domestic market, sales of tea packaging materials are used in a wide range of currently mainly PET bottles and aluminum cans. This is mainly because of China's tea market just a view towards the introduction of growth stage. Early use of three-piece tinplate cans as a tea beverage packaging business due to product cost is too high, high prices have been gradually phased out. Heat-resistant PET bottle of tea beverage processing process is simple, quality and easy to control, easy to start small and medium enterprises. Aluminum cans by domestic sales of carbonated tea beverages Wang Shi influence, and its annual consumption of tea drinks, very impressive.
There are some manufacturers use of non-heat-resistant PET bottles as a tea beverage containers, but most are not very good quality of the product, shelf-life period of serious browning appeared tea color, sedimentation, metamorphism and so on. This is because most manufacturers are using mineral water filling line for PET bottled tea drinks, as production equipment, and the present equipment, mineral water filling line, does not apply to tea beverage aseptic filling, or about 60 ℃ hot filling loaded, its less stable, filling the environment when you are not stable and prone to secondary pollution, leading to excessive bacteria, tea degenerate.
Currently used as a tea beverage aseptic Tetra Pak packages are basically Taiwan-funded enterprises, such as unity, Master, life, etc. Also, as the sun rose, Huiyuan, deep Hui, Hui-Er-Kang has adopted this part of the manufacturer's financial strength more abundant, but also a wealth of experience in tea production. Their products taste good, stable quality, sales situation and optimism in recent years, China's tea market share of sales is high.
Tea beverage packaging trends
The first is a drink of tea drinks, so virtually all appear in the other beverage packaging in the tea drinks are applied. However, tea has its own characteristics: ① The polyphenols in tea drinks substances and their oxidation products during storage easily with caffeine, soluble protein, pectin formation of turbidity and sedimentation; ② the polyphenols is also easy to oxidation, easy to form a black complex with iron ions resulting in color and flavor drinks on the Deterioration; ③ tea a long time at high temperature sterilization, easy to lose flavor and is easy to produce and cooked Tang Wei (cooked flavor), thus affecting the tea itself, flavor; 5 tea drinks are mostly low-acid beverages (PH ≥ 4.5), generally high-temperature sterilization; ⑤ mostly popular drink tea beverage is required at low prices to stimulate consumer desire to purchase.
Most beverage manufacturers more from the equipment, one-time investment costs and production costs up to consider the choice of type of packaging, while ignoring the characteristics of their own tea. For now appearing on the market a variety of packaging point of view, in order to wrap sterile composite aluminum and PET bottles for packaging of tea drinks more appropriate to the nature of its chemical stability, not with tea in the chemical reaction of substances. The sterilization process using ultra-high temperature instantaneous sterilization processes (UH T), filling processes commonly used filling sterile environment or hot filling, can maintain Tea flavor. Another sterile wrap and aluminum composite made of PET bottles can be a greater capacity, packaging, suitable for families and party spending. From Japan and Taiwan in recent years the development of tea beverage packaging point of view, can also be found in large volumes of packaging is a trend.
