beer
In recent years, the international use of heat-resistant PET bottles (PET) packaging beer, in particular PET bottle coating technology (plasma technology) applications, with a 0.21mm carbon coating, its barrier properties are almost the same as glass, At the same time, it can withstand high-temperature sterilization treatment, expanding its scope of application, adapting to hot filling tea drinks and other packaging. In addition, the new polyester bottles of polyethylene naphthalate (PEN), which are attracting the attention of the packaging industry, are entering the beer industry, leading to innovations in beer packaging. Due to the similar molecular structure between PEN and PET, the naphthalene ring is used instead of the benzene ring, making PEN more excellent in barrier properties, UV resistance, heat resistance, and high temperature resistance than PET. (The amorphous PEN thermal transition temperature reaches 100°C. PET is only 70 °C). Since naphthalene is separated from coal tar, China has a rich source. In the near future, PEN will enter the packaging field in large quantities and will trigger another packaging revolution following PET.
The next step is whether to use glass or plastic packaging, the key is to see whether consumers recognize PET bottled beer. The current situation is that the plastic bottle process almost overcomes all technical problems and the shelf life can also meet the sales requirements. China is the second largest beverage market in the world, and the demand for beer packaging is huge. Therefore, with the popularization and promotion of the PET bottled beer market, it will also occupy a certain market share. In the existing consumer market, as Zhuhai Zhongfu has a leading position in the field of PET bottles, Haizhu Beer and Macau Beer, which are filled with PET bottles, have also received certain recognition from consumers.
fruit juice
In 2003, Australia successfully developed a juice packaging cup with high shielding performance. The shelf life of the cup packaging is 18 months. 3-layer co-extruded structure containing a layer of PP, a layer of EVOH, a layer of adhesive layer. The outer layer of PP can absorb ultraviolet rays, and the transparent packaging cup has high shielding performance, which can prevent the juice and jelly from discoloring under the light. The cup uses the packaging machine 'target=_blank> transparent film cover, which can be filled hot or cooked. Single-color or two-color gravure printing is used on thermoformed deep-drawn cups. Partial printing can be performed on the packaging machine 'target=_blank> cover and cup. The cup is wrapped in a paper sleeve and can be printed in 6 colors. With a diameter of 89.4mm and a depth of 105mm, the cup replaces part of the metal cans for packaging juice and jellies. The application prospect is very broad.
Tea beverage
At present, modern science and technology have broken through many problems in the production of tea beverages, and packaging and storage have become the key to which manufacturers must pay attention. At present, popular tea beverage packaging around the world includes glass bottles, metal cans, paper-aluminum-plastic composite brick type Tetra Pak, polyester bottles (PET, PEN), etc., while domestically used metal three-piece cans, Tetra Pak Bags and PET bottles.
Most domestic tea beverage manufacturers have set up a three-piece can production line. The advantages of metal cans are their strong adaptability to processing, low loss, excellent barrier properties, and colorful packaging printing. However, its production cost is high, and the requirements for interior coating are more stringent because canned teas often have quality problems due to non-uniform coating of the cans, and they do not meet the environmental protection requirements when they are discarded. With restrictions on the market, capital and technical conditions, the national industrial policy still does not allow large-scale promotion, but there are still certain needs in large and medium-sized cities.
PET is a kind of pressure-resistant polyester material, which is cheap, and has good transparency, airtightness and compressive strength. As domestic consumers pay special attention to tea beverages, when manufacturers introduce new tea beverage products, they must fully consider the taste, flavor, and product characteristics of tea consumption around the country. At the same time, they must also shape individual packaging of tea beverages that differ from ordinary soft drinks. In particular, polyester packaging with excellent performance, elegant appearance and economical convenience. For example, "Tea King" series of tea beverages are packed in polyester bottles, and they are especially matched with the whole bottle body's logo decoration. It is similar to the "Kirin" tea packaging.
