UHT Milk "Replacement" PET bottle for the first time

KRONES presents the new technology of PET bottled UHT milk to the eyes of the world. The emergence of this technology has not only enriched the packaging form of milk, but also broke the market pattern of “consisting in the world” with paper containers such as Tetra Pak and Combibloc.

The process of filling milk and processing can be seen in the right table.

The main principle of KRONES's new aseptic filling technology is that the PET bottles are sterilized on the inner and outer surfaces of the bottle wall before the milk is filled (ie, the “washing” process), and then in a sterile environment. The milk is filled and the bottle caps are closed, and finally the caps are sterilized in a sterile environment. After this series of processes, a bottle of PET bottled milk was produced.

The advantages of PET bottled milk are:
● There is almost no lack or change in milk taste or color;
● No need to add preservatives;
● The PET bottle has a thin wall, a flexible design and a low cost.

If dairy companies adopt this technology, the change in packaging containers will not only make their products “light up” for consumers, but also the good taste and long shelf life will make consumers very satisfied.

This new form of milk packaging has been used by foreign dairy companies and has performed satisfactorily in the actual production and sales process.
The Centrale del Latte di Brescia SpA milk company based in Brescia, a city in northern Italy, produced the world's first PET bottled UHT milk with a shelf life of 90 days.

The new aseptic filling technology was provided by KRONES, a global market leader in beverage filling and packaging technology, in Neutraubling, Germany. A compact PET separation aseptic filling line can reach a filling volume of 12,000 bottles per hour on a small site. The 0.5L and 1L PET bottles used for this product are produced by KRONES' Contiform S high-strength stretch blow molding machine. The aseptic filling system was installed and put into operation in January 2004 and was successfully certified by a third-party testing laboratory in May.

In order to obtain a longer shelf life of milk, PET bottles have gradually replaced hard carton packaging. The Centrale del Latte di Brescia SpA Dairy Company has conducted extensive and in-depth studies on the characteristics of PET bottles and the possible interaction between PET bottles and milk. The results of their research are all good.

It is believed that with the continuous development of the dairy market, PET bottled UHT milk will be favored by consumers with its flexible and diverse packaging forms, good taste and rich nutrition.
