Temperature tests of up to 50°C have been undertaken. Results indicate that the Petainer still performs within specification, but the effect on product is questionable.

Will PET taint/affect the flavor of my product?

No, Petainer has contracted independent taste studies with trained taste panels that confirm that petainerKeg™ does not affect the flavour of the beer or wine even after 12 months of storage. The studies also highlight that the PET taste results equal the results of stainless steel kegs.

Scientific research confirms this:

Do petainerKegs protect the quality of my product?

Use of ‘barrier technologies‘ to prevent oxygen ingress and maintain product quality is just one of the reasons we are the system of choice for breweries in many countries:

Report on taste testing

PET slows the egress of CO2, and a pigment protects against harmful UV light. Recent findings indicate that Petainer's PET blend not only prevents the ingress of Oxygen, but actively reduces dissolved oxygen, if present, in product.

How robust is the ‘cardboard’ carton in transport?

Our cartons support your products throughout their lifecycle if kept dry, and are handled with reasonable care.

Although not load bearing (like the polypropylene sleeves used on our 20l and 30l USD formats), all Petainer packaging uses less space, and can be 100% recycled at source (where facilities allow).

Can a bar’s beer line be cleaned while dispensing from a Petainer?

Yes, please direct your team to the following...

To disconnect:

1. Position the keg in an upright position.

2. Wrap a cloth around the fitting and dispensing head.

3. Pull the dispensing head handle upward.

4. Turn the dispensing head counter-clockwise and gently remove it from the keg, releasing pressure through the automatic pressure relief valve.

5. Keep the keg upright and cover the ‘open’ fitting.

Reconnect as quickly as possible:

1. Push the dispensing head into the ‘open’ fitting.

2. Hold the fitting with one hand, and with the other, turn the dispensing head clockwise until it stops.

3. Keep hold of the dispensing head, release the keg and push down the dispensing head handle.

The keg is ready to dispense.

How does the Petainer NPR valve work?
Kegs available on the G3 Online Store feature Non-Auto Pressure Release fittings (NPR) fittings and recyclable depressurizing tools. The NPR valve allows kegs to be tapped and untapped multiple times for easier use. Kegs come equipped with a venting tool, that is slid over the neck of the keg after it is filled.
The venting tool should ONLY BE USED AFTER KEG HAS BEEN EMPTIED. Once the keg is emptied the tool can be fitted into t
he valve, the valve will “open” and the keg can be crushed and disposed of.D npr valve for keg
