German company Schreiner ProTech has developed a new tap seal for the Huber Packaging Group's five-litre Draftking beer keg.

According to Schreiner ProTech, a business unit of Schreiner Group, beer poured from the party keg retains its freshness for up to one month.

The specialty seal can be used by breweries to advertise their brands by having the labels custom-printed with their logos, and cannot be closed again without being noticed once the keg has been opened, ensuring reliable authenticity protection.

The seal comes with an adhesive that ensures better bonding with the low-energy plastic material of the tap.

Schreiner ProTech said the project development aims to achieve a process-stable authenticity seal for the Draftking beer keg.

Huber Packaging Group beverage business unit manager Markus Britsch, commenting on the new development, said, "The authenticity seal has to be particularly sturdy to withstand the production environment of the filling lines and external cleaning of the kegs at the breweries."

Initially, material tests were conducted by the experts from Schreiner in the laboratory to guarantee rugged marking and functional adhesion of the label, to qualify the film.

The company adjusted the material, liner and roll make-up to the high cycle rate of the keg production line, and the label dispensing system was developed in such a way that it guarantees trouble-free application, as the seals are dispensed in parallel to the automated production run.

By using flexo-printing technology, Schreiner pre-prints the original seals with brand graphics.
