petainerKeg™ Range & Specifications

Standard petainerKegs are currently available in three sizes - 15, 20 and 30 liters (The 15L variant is not available in South Africa). The 20 and 30-liter kegs are also available in a version that is specifically designed for use on existing filling lines for metal kegs.

petainerKegs are designed for counter pressure filling.The volume of the filled keg will depend on the pressure used. All the kegs offer economic and environmental benefits when compared with metal kegs and other plastic variants. The benefits increase with the size of the keg - the larger the keg, the larger the savings.

The current range of sizes and the associated range of fittings mean that there is a suitable keg for almost every beverage application in bars, pubs, clubs and restaurants worldwide. In addition to beer, petainerKegs are suitable for a range of beverages including cider; wine, water, concentrates and low pressure carbonated soft drinks.

Product Specification


petainerKegs are manufactured from PET (Polyethylene Terephthalate) with a small proportion of nylon and a brown colorant. Fittings are made from plastic materials: POM (Polyoxymetylen), PP (Polypropylene), TPE (Thermoplastic Elastomer) and a stainless steel metal spring. All the materials used are approved for food use by the European Union and by the FDA in the USA.


Standard petainerKegs can be filled in small quantities using standard filling machines with an adapter from petainer’s partner KHS. However, for commercial volumes petainer recommends the use of specific equipment from KHS. Variants of the 20 and 30 liter keg in polypropylene casings are available that are specifically designed for use on existing filling lines.


petainerKegs can be supplied in outer cardboard boxes or with adapters to fit existing racking systems. On conveyor lines and automated filling machines they can be lifted by the neck when empty. Variants of the 20 and 30 liter kegs designed for use on existing filling lines are supplied in polypropylene casings. Clip on/clip off handles are available to assist with one-person or two-person manual handling of kegs in breweries and filling plants.

Hygiene and Safety

Kegs, preforms and fittings are manufactured under hygienic conditions in ISO 9000 and ISO 14000 certified plants.

Disposal and Recycling

The PET petainerKeg™ can be easily crushed and then recycled through the municipal or commercial plastics bottle-recycling infrastructure which exists in most developed markets. The fittings and cardboard carton or polypropylene casing are also recyclable. The petainerKeg™ is 100% compliant with EU packaging waste directive 94/62/EC and is recyclable according to European Standards EN 13428, EN 13430 and EN 13432.

Kegs For Existing Filling Lines (USD Kegs)

Versions of 20 and 30 liter petainerKegs are available that are specifically designed for existing brewery filling lines used for filling steel kegs. These are traditionally filled with the opening in the keg facing downwards and sealed onto the filling system.

The adapted version offers brewers the opportunity to gain all the advantages of the petainerKeg™ without needing to invest in new filling systems. The kegs are supplied in rigid polypropylene casings, which facilitate use on existing filling lines. The casings also make the kegs easy to handle in transport and by users in bars, clubs and restaurants - replacing the cardboard cartons of standard petainerKegs.

Like the petainerKegs themselves, the casings are designed for one-way use and are fully recyclable. They can be printed to users’ specifications to create new opportunities for branding.
