Analysis Of Composite Pet Bottle Life
Germany Dole is a major fruit juice producer, has recently conducted a thorough PET bottle packaging fruit juice shelf life test
.
Because Dole's products in the market play an important role in leading the fruit juice flavor, so for each brand, the company has a great interest in the final package to the shelf period, to ensure product quality. Containers have a number of components of any deficiencies in the required tolerance. Development of one of the most effective and most suitable packaging objects, not only convenient and practical, and safe and beautiful, these are very important. PET bottles in these areas played a pivotal role. 25 years ago, regardless of any type of liquid with a glass bottle packaging.
The implementation of plastic bottles, due to its long list of practical and design advantages of the conversion played a role in the market, replacing the glass, and enduring, this trend mainly due to the enthusiasm of users and retailers.
A market is expanding with the beverage market continues to expand, not only launched a new brand, and the emergence of new market component. Such as mixed fruit juice, yogurt fruit juice, vitamin juice and sports drinks. The emergence of these new varieties are needed with the new packaging, in particular the protection and preservation products. High-quality products require high-quality packaging. Polyester industry to develop effective response to market demand, such as: multi-layer PET bottle, hot filling PET bottles, PET bottles coated with glass bottles and metal containers can be comparable. Like many music vendors such concern is that multi-layer PET bottle retailers can ensure the requirements: at least six months shelf where the shelf, but also promised to provide to the consumer satisfaction of taste and quality.
This end, many music companies in 2002, yogurt juice drinks for the "sun" accelerated shelf life test. This is the AMCOR0. 5-liter PET bottle, using the heat sealing method of irrigation. Test confirmed that the shelf life of six months - than the standard (general) PET bottle with a huge three-month maximum life span increase. Meanwhile, more than music has also completed another important shelf-life test: the purpose of comparison with the standard multi-layer PET bottle PET bottle packaging effect. Long-term storage of neutrons in the case of drinks, more into these four aspects: color and flavor, vitamin loss (ascorbic acid) and the carbonation level. The three AMGUARD multilayer PET bottle with a single-layer PET bottle and a glass, are fitted with 500 ml of product was sealed test. This four from the AMCOR PET bottle PET bottle production plants each weight 28 grams. 3 AMGUARD multi-layer PET bottle with BIND-OX activity in blocking oxygen scavenger, and two other bottles of Participating the UV protective agent. 1 is a UV protective agent Participating polyester raw materials; the rest are ordinary white transparent bottle. Glass bottles sealed with the metal cover, and the polyester bottle cap with the anti-oxidant. The choice of beverage bottle packaging is very important role, and if the bottle caps can not provide the same protection and the role, then the protective effect of the bottle will be reduced.
Choice test product is cold filling (not sterile), light carbon (6 g / l) of the other sports drink mixed with orange (including 6% orange juice). This drink is considered by the representative of the typical beverage category.
Test conditions: test temperature at 21 degrees continuous light conditions, real time with a 6 months. This is the "worst conditions" under the test. Real life is not any product placement in such a high temperature for six months. Testing center is 4-6 months, samples will be tested, testing two main areas: technical data and appearance and taste. Vitamins: Once oxygen into the bottle through the product will lose vitamin C, flavor will deteriorate. Dole company to detect the loss of vitamins into the rate of penetration of oxygen, vitamin product existing large 350PPM. The loss of vitamin, multi-music company is high-resolution liquid chromatography (HPLC). Carbonation level: STEIFURTHSYSTEM carbon intensity using the method of temperature and pressure can be accurately determined.
Music companies and more understand that, when the beverage carbonation level of less than 4 g / liter, consumers will feel, because when filling up to 5 g / liter. Taste: Dole's expert sampling phases, separated by percentage.
Color: Color is always in the six months per bottle test, test proportion gradually become brown. Xiao Bian excellent Recommendation:
