PolyKeg PRO with bag

PolyKeg PRO kegs with bag are supplied with the unique and exclusive Bag in Keg (BIK) system which guarantees correct tapping, avoiding excessive foam and product loss.

In addition, the special multi-layer film employed in the BIK system provides a high barrier to light, O2 and CO2, ensuring maximum protection of the product before and during tapping.

BIK System

Unique and exclusive to PolyKeg®, The Bag in Keg (BIK) system is available with 6 valves and is compatible with the most common existing tapping systems.

The only system with a dip tube inside the bag that ensures a proper and complete tapping, avoiding excessive foam and product loss.

It guarantees maximum protection of the product, before and during tapping, thanks to the innovative bag design, made with a special multi-layer film that provides a complete barrier to light, O2 and CO2, as well as a superior resistance to breakage and puncture.

It is ready for filling without any additional steps and extra costs on the customer's side. The bag kit is supplied flushed and vacuum sealed to ensure the absence of residual oxygen and excellent sanitary conditions inside the bag.
