Download the FREE petainerKeg App
I'm a maker Brewers, Cider makers and Vintners look to petainerKeg™ as an alternative to the massive historical capital investment in steel kegs. This option allows makers to send their product into new markets without risk and reduced cost. I'm a brand owner Brand Owners will enjoy opportunities in new markets as well as the brand exposure via packaging. I'm a distributor International distribution companies benefit from the classic keg with reduced storage, no return costs and reduced cost and theft that can open up new markets to them. I'm in the trade Publicans, Restaurateurs and Hoteliers can now reduce storage as petainerKeg™ can be crushed and recycled in one piece. The taste quality of the product is as good as, if not better, than the same product in steel keg.

What is the shelf life of my product – in a petainerKeg™?

The shelf life offered by any container is influenced by the sterility of the product inside, the filling process and the sterility of the container. The ability of the container to prevent the ingress of oxygen / egress of CO2 and protect from UV light are also important.

Petainer Kegs are delivered clean and micro-biologically sterile. The PET/scavenger contains nylon. As such, they can offer a shelf life equal to or better than any "standard" metal containers.

petainerkeg™ provides a filled shelf life of 9 months. Once the keg is tapped and operational, the product inside the keg is recommended to be used with a shelf life of 6-9 weeks.

petainerKegs contain a brown pigment within the plastic, and are transpored within a carton to eliminate UV light.

Is a blown keg delivered sterile and pressurised with CO2?

Blown petainerKegs are delivered clean and micro-biologically sterile. They are pressurised with sterile air.

Before filling, kegs must be purged (to remove O2) using inert gas – typically CO2, N2, or mixed gas.

Standard petainerKeg™ are suitable for carbonated products. Please contact Petainer before attempting to use with nitrogenated products.

Can I fill a petainerKeg™ on my current keg line?

20 and 30 litre keg formats have been designed for use on some existing, suitably modified metal keg filling lines.*

All petainerKegs reduce the cost of fleet storage and cleaning. In addition, USD kegs bring the benefit of experiencing PET technology, without initially investing in new filling systems.

Will PET taint/affect the flavour of my product?

No, Petainer has contracted independent taste studies with trained taste panels that confirm that petainerKeg™ does not affect the flavour of the beer or wine even after 12 months of storage. The studies also highlight that the PET taste results equal the results of stainless steel kegs.

Scientific research confirms this:
