Beer in a CarboPouch

The development of the CarboPouch, a stand-up pouch for low-carbonated drinks, opens the possibility for draft beer microbreweries to fill on-site clean, ready-to-go stand-up pouches, featuring a spout and a cap. Storage and shelf-life requires refrigeration, but the organoleptic film structure ensures no intrusion of flavour and is designed to handle the pouch ‘stretch’ after filling and carbonation expansion.

The stand-up pouch technologies most recently developed by PPi Technologies Global contain flexible stand-up pouches for wine, beer and spirits. Besides the interesting VinoPaQ, which is targeting the bag-in-box wine market as an alternative, is the eye-catching and much more interesting stand-up pouch for low-carbonated drinks, such as beer. Although stand-up pouches for drinks are quite common, the technology for flexible stand-up pouches for carbonated drinks is clearly a dimension higher.

The BeerPaQ, also known as CarboPouch, is developed targeting the small craft beer brewers, who, in several countries, are located in a restaurant or supermarket. But also the organisers of big sports or music events now have the possibility to fill clean, ready-to-drink, single portion, non-dangerous Single45 of Single25 stand-up pouches with beer. The CarboPouch can also be filled with low-carbonated water.

The film structure is designed to handle the pouch ‘stretch’ after carbonation, and the filling process doesn’t leave a ‘free headspace’ in the stand-up pouch after filling. The three-side sealed stand-up pouch fits perfectly in the hand and while neither sun light nor oxygen can interfere the beer has a shelf-life of 30 days in the refrigerator. The BeerPaQ has a 90% less CO2 footprint in comparison with an equivalent Bag-In-Box packaging.

The Single45 is a 16 oz. (454 ml) and the Single25 an 8 oz. (227 ml) stand-up pouch. Multi64 (1,8 litre) bulk pouches are available for outdoor activities. Also available is a 150ml size for children and is used for water; 200ml, 250ml, and 300ml sizes are also available.

The film structure used for the traditional standard stand-up pouch is fairly thick to give it a certain stability before opening, but almost none stability after opening. The CarboPouch gives a rigid stand-up pouch for low-carbonated drinks (with the exception of carbonated soft drinks), which also offers a stability after opening.
In contrast with traditional stand-up pouches, the CarboPouch stands upside-down, resting on its tamper-evident closure, which is located over the threaded drinking fitment.
