Petainer HYBRID Kegs are the first one-way kegs to use a circular economy design. They are fully compatible with automatic fillers and universal fittings. 

Petainer, the market leader in one-way PET kegs, is launching its new 30L and 20L Slimline petainerKeg Hybrid kegs at this year’s Brau Beviale  Hall 4 / 4-137.  The new formats complement the standard 20L Hybrid which is already in use around the world.

Hybrid is the first one-way PET keg to use a circular economy design, focused on recycling and reuse.  Designed for drinks producers such as breweries and wineries as a more cost-effective and sustainable alternative to traditional stainless-steel kegs, the keg provides a low-cost way of entering new domestic and international markets.

The keg’s snap-fit design allows for local blowing and assembly, reducing the carbon footprint of transport, as well as easier disassembly for better recyclability in market.  It is also the only keg where the top and bottom chimes can be reused by the brewery.  By removing return logistics and washing processes because it is filled, sent and recycled when it is empty, the keg reduces supply chain costs by up to 40% versus steel.

The Hybrid keg portfolio is designed to support brand expansion to new markets with improved safety features like puncture and drop resistance, burst pressure over 7bar and is fully functional at 40oC.  At just 10% the weight of a steel keg, the Hybrid provides superior stacking and handling for filling, transport and storage tested to ASTM standards for sea and road transportation making it ideal for export markets.

The new Hybrid kegs are suitable for hand filling and the majority of automatic keg filling lines, which means it can be used in breweries and retail outlets anywhere in the world without any additional capital expenditure required to switch from traditional steel kegs.

Like other products in the petainerKeg range, Hybrid can also be used with universal coupling systems, with flat fittings compatible with Micro Matic A and G systems and well-type fittings compatible with Micro Matic S and D systems, so customers know their product can be dispensed anywhere in the world.  In addition, the 20L Slimline Hybrid has been designed so that it fits in standard kegerators.

The kegs blended barrier provides protection from O2 and UV light while retaining CO2 to provide that straight from the brewery’s taste.  Independent tests show that the keg keeps the beer as fresh as other containers in the packaging mix.  Taste tests* conducted by the globally respected VLB Institute show that after nine months the taste is on a par with steel kegs.

“Our team of polymer scientists and technical experts have developed the first one-way PET kegs which have been designed with end of life in mind.  This, and the significant supply chain benefits Hybrid offers, minimises its environmental impact.  The Hybrid range provides breweries and drinks producers with a cost-effective way of building their brands in new markets and ensuring their product arrives in optimal condition.”
