20L One Way PET Beer Keg Manufacturer
BaiXi supplies wholesale 20L one way PET beer kegs for breweries, beer distributors, taprooms, bars, restaurants, events and export beer distribution. Designed with a PET outer container and a flexible inner bag, this disposable beer keg helps reduce return logistics, keg loss, cleaning costs and storage pressure.
The 20L PET beer keg is suitable for craft beer, draft beer, small-batch beer, festival supply, restaurant dispensing and one-way beer delivery where stainless steel keg return is expensive or difficult.
20L Disposable PET Beer Keg for Breweries
The 20L one way PET beer keg is a lightweight and practical alternative to traditional stainless steel beer kegs. It is designed for single-trip beer distribution, which means the keg does not need to be returned, washed, stored or maintained after use.
For breweries expanding into new regions, temporary events, restaurant supply or export distribution, one way PET kegs can help simplify logistics and reduce operational complexity.
Features and Benefits
One Way Disposable Design
No return logistics are required after use, helping breweries reduce keg tracking, loss risk and return management.
Flexible Inner Bag System
Beer is stored inside a flexible inner bag, helping reduce direct contact between beer and oxygen during dispensing.
No CO2 Cylinder Required
Pressurized air compresses the inner bag from the outside, pushing beer out smoothly without a separate CO2 cylinder.
Lightweight PET Container
PET material makes the keg lighter than stainless steel kegs, improving handling and transportation efficiency.
20L Brewery Volume
The 20L capacity is suitable for bars, restaurants, festivals, taprooms and brewery distribution.
Recyclable Packaging Concept
PET material supports recyclable packaging strategies for breweries and beverage brands focused on sustainability.
What Is a One Way PET Beer Keg?
A one way PET beer keg is a disposable draft beer container made with a PET outer shell and an internal flexible beverage bag. Unlike reusable stainless steel kegs, it is designed for one-way distribution and does not need to return to the brewery after use.
This makes it useful for breweries selling to distant customers, export markets, outdoor festivals, temporary events or locations where collecting empty kegs is difficult.
How the Inner Bag System Works
BaiXi PET beer kegs use a bag-in-keg dispensing principle. Beer is filled into the flexible inner bag. During dispensing, compressed air is applied between the PET shell and the inner bag. The pressure pushes the beer out from the bag while helping reduce direct oxygen contact.
- Beer is stored inside the flexible inner bag.
- Air pressure is applied outside the bag, not directly into the beer.
- The beer is dispensed smoothly through the coupler.
- The design helps reduce oxidation risk during dispensing.
- No separate CO2 cylinder is required for distribution use.

Solutions for Breweries
Pain Point 1: High Stainless Steel Keg Investment
Stainless steel kegs require higher upfront investment and safety stock. Breweries also need storage space and inventory management for empty and filled kegs.
BaiXi Solution: One way PET kegs can be ordered according to actual distribution needs, reducing long-term keg stock pressure.
Pain Point 2: Complex Cleaning Before Filling
Reusable steel kegs must be professionally washed, sanitized and inspected before filling, which requires equipment, labor and production time.
BaiXi Solution: Disposable PET kegs simplify the preparation process and reduce repeated keg washing requirements.
Pain Point 3: Maintenance Cost
Stainless steel kegs, gas cylinders, regulators and accessories need inspection, maintenance or replacement.
BaiXi Solution: One way PET beer kegs reduce long-term maintenance responsibility and help simplify distribution equipment management.
Pain Point 4: Keg Loss
Reusable kegs move through breweries, distributors, retailers and end users before returning. This cycle is long and kegs may be lost.
BaiXi Solution: Disposable PET beer kegs do not need to be returned, helping reduce loss risk and return tracking.
