Dolium kegs are made from Invista® PET Polyshield® blended with 5% MXD6 Polyamide. This combination provides an oxygen barrier (Polyshield) and CO₂ retention (MXD6 Polyamide) while being 100% recyclable.

Dolium kegs are available in four sizes: 30L/7.97Gal Prime, 20L/5.28Gal Slimline, 12.5L/3.306Gal Slimline, and 24L/6.346Gal Prime. Every size is delivered within 2 weeks.

Dolium kegs have excellent gas retention properties. The CO₂ loss stays below 5% after 6 months, so your beverage keeps its carbonation throughout its shelf life.

No special equipment is needed. Dolium kegs are compatible with all standard filling systems and dispense equipment. They come with standard A, G, S and D spears and work without modification.

You don’t! That’s the beauty of Dolium one-way kegs. They come pre-sterilized and ready to fill. No cleaning, washing, or sanitizing is required, saving time, water, and chemicals.

Dolium kegs are perfect for beer, alcohol-free beer, wine, ciders, cold brew coffee, kombucha, and other craft beverages. The kegs limit CO₂ loss to less than 5% after 6 months and provide active oxygen barrier protection, ensuring your craft beverages reach consumers with perfect quality. Available in 30L, 20L, 12.5L, and 24L sizes to match different market needs.

Storage time depends on the beverage type, but the advanced barrier technology ensures extended shelf life. For specific recommendations for your beverage, please consult our technical team.

Dolium kegs should be stored in a cool, dry place away from direct sunlight, similar to any other beverage container. The kegs include UV protection, but avoiding direct sunlight helps maintain optimal product quality.

Absolutely! Dolium kegs are 100% recyclable and require no cleaning water or chemicals. They’re designed for the circular economy.

Dolium kegs are ideal for export markets due to their lightweight design and no return logistics requirement. We have distribution centers in Europe and the USA to serve global markets efficiently.

Dolium kegs offer significant advantages over traditional stainless steel kegs: zero upfront capital investment (traditional kegs require €30-60 per unit), no cleaning costs (saving 3-5L of water and chemicals per keg), 40% lighter weight for reduced shipping costs, no return logistics needed, and zero keg loss or theft risk. Dolium kegs maintain the same compatibility with all standard filling and dispense systems (A, G, S, D spears) while limiting CO₂ loss to less than 5% after 6 months and providing active oxygen barrier protection.

The total cost of ownership for Dolium kegs is significantly lower than traditional stainless steel kegs. Stainless steel kegs require €30-60 upfront capital investment per unit, plus ongoing costs for cleaning (water, chemicals, energy), maintenance, tracking systems, insurance, and reverse logistics. Dolium eliminates these costs entirely: no capital investment, no cleaning, no return logistics, no loss prevention costs. For low-rotation markets and export, Dolium typically delivers 30-50% total cost savings compared to traditional keg systems.

Yes. Every keg comes with a standard A, G, S or D spear and runs on your existing filling and draught equipment. No special heads or couplers needed.

The patented APRV (Automatic Pressure Relief Valve) opens at 5 bar and re-closes at 2 bar. An oxygen barrier and a CO₂ loss of less than 5% after 6 months protect the beverage in transit.

No capital, no cleaning, no return logistics, no loss. On low-rotation and export routes that is a lower total cost than stainless steel.

Up to 18 months of barrier protection. The product sheets give a best before date of 18 months after production, and the CO₂ loss stays below 5% after 6 months.

Four volumes: 30L Prime, 24L Prime, 20L SlimLine and 12.5L SlimLine, delivered within 2 weeks. Every model comes with a standard A, G, S or D spear, and can be prefilled with N or CO₂ if you want.
