30L Disposable Plastic Beer Keg for Breweries
The 30L disposable plastic beer keg is a one way draft beer packaging solution for breweries that need flexible distribution without empty keg return. Compared with reusable stainless steel kegs, disposable PET kegs can simplify logistics, reduce keg tracking work and help serve distant or temporary markets more efficiently.
Features and Benefits
One Way Distribution
No return logistics are required after use, helping reduce keg loss and return management.
30L Draft Beer Capacity
Suitable for bars, restaurants, distributors, events and brewery draft beer supply.
Flexible Inner Bag System
Beer is stored inside the inner bag, helping reduce direct oxygen contact during dispensing.
No CO2 Cylinder Required
Pressurized air squeezes the inner bag from outside and pushes beer out smoothly.
Lightweight PET Body
The 30L unit weighs about 1.92kg, making handling easier than traditional metal kegs.
Recyclable PET Concept
PET material supports recyclable packaging strategies, depending on local recycling conditions.
How the Inner Bag System Works
BaiXi disposable PET beer kegs use a bag-in-keg dispensing principle. Beer is filled into the flexible inner bag. Compressed air is applied between the PET outer container and the inner bag, pushing beer out smoothly while helping reduce direct oxygen contact.
- Beer stays inside the flexible inner bag.
- Air pressure is applied outside the bag, not directly into the beer.
- The keg dispenses beer through a T type coupler.
- The design helps support freshness during draft beer service.
- No separate CO2 cylinder is required for distribution use.
