The choice of plastic keg




It always takes a lot of efforts for the breweries to have a perfect beer, especially for the craft beer, normally it takes weeks or even months efforts, and when you bring your perfect products to the consumer with delight, maybe you need to consider how to fill your beer, in stainless steel keg or plastic keg? cost wise, and also to protect your perfect product in perfect quality for long time.

it’s an important decision sometimes, everybody want to have as much as possible low cost for sure, but still nobody want to loss their perfect beer, as it take so much efforts of them.

a lot of factors need to be considered by the breweries when they choose which type of kegs for their beer, e.g. cost, safety, easy to use, weight and transport, quality, shelf life, to keep the original taste/flavor, etc… these make the choice difficult, but every breweries should have their own priority for their perfect products, and from the comparison below for the beer kegs, every breweries should be able to find their prefer kegs to fit their demand for their perfect beers.



the benefits of stainless steel keg:

-        durable, a stainless steel keg can be used for many years if with good maintenance.

-        safety, no explosion even if under high pressure

-        low cost (per glass of draft beer), as it’s reusable.

-        long shelf life, can prevent the O2 migrated into beer and prevent the loss of CO2

-        can keep the original taste of beer, and prevent the flavor loss from the beer



the disadvantage of stainless steel keg:

-        too heavy, transport cost increasing

-        easy to be stolen or lost, part of them can not be returned.

-        expensive to buy a new stainless steel keg

-        need cleaning, drying, sterilization, etc…

-        possible chemical residue from the cleaning process.

-        big investment for cleaning line, big area to be needed too

-        need good maintenance, especially for the sealing rings and slight cracks caused by deformation, not easy to be detected.

-        beer contact with air and some O2 solved into beer during filling

-        the filled beer can not be 100% used, the last glass (normally about 500ml) will be lost



the benefits of one-way plastic keg:

-        lightweight, transport cost saving

-        one-way use, no stolen and lost issue

-        low cost to buy a new one-way plastic keg, easy for breweries to boost their sales in peak season

-        no cleaning, drying, sterilization needed, no relative investment for such process.

-        no chemical residue from the cleaning process

-        small area to be needed for filling process

-        no maintenance needed

-        for one-way keg without bag, beer contact with air and some O2 solved into beer during filling; if one-way keg with bag, no O2 solved into beer during filling

-        for one-way keg without bag, the filled beer can not be 100% used, the last glass (normally about 500ml) will be lost; but for one-way keg with bag, the beer can be 100% used.



the disadvantage of one-way plastic keg:

-        only one time use, the cost per glass of draft beer is higher than the stainless keg

-        the PET one-way keg can not stand high pressure, possible to be exploded under high pressure and cause safety issue.

-        the barrier performance to both O2 and CO2 is not as good as the stainless steel keg, the shelf life is shorter than the stainless steel keg.

-        difficult to keep the original taste of beer as CO2 loss as well the flavor loss.

-        possible small molecule migrated into beer, and react with the chemical content in the beer, and cause the flavor/taste change of the beer.



so, every type of keg has its benefits and its disadvantages, it’s difficult to say which type of keg is the best, it depends on different application for the kegs.

normally, for local market, stainless steel keg is much better than the one-way plastic keg; for export market, considering the returnable of the keg, relative cost, etc., the one-way plastic keg should be better, but if long shipping time need long shelf life, high temperature need strong keg, etc., then, some of the one-way plastic keg could be still inappropriate.

on the other hand, for small breweries, especially for home breweries, it’s a fact that it’s not possible for them to have too much investment to have a full automatic cleaning and filling line for the stainless steel keg, that way, the one-way plastic keg seems a better choice for them.

is there any keg which has all the benefits of both stainless steel keg and plastic keg? so that it’s easy for most of the breweries to choose the keg for their perfect beer? we can tell you: yes, there is one.

with many years research and development, we have a plastic reusable beer keg, it’s the first launched reusable plastic keg all over the world, it combine all the benefits of stainless steel keg and plastic kegs: cost, safety, easy to use, weight and transport, quality, shelf life, to keep the original taste/flavor, etc….. the core technologies including patent high tech multi barrier technology for long shelf life, strong and enough elongation of keg body for safety/no risk of explosion even under extremely high pressure, special polymer to prevent any small molecule migrated into beer, with the extremely high barrier performance together, to keep the original taste/flavor of your perfect beer during the whole shelf life, etc…… with such a  highest quality kegs, and our experts, we are sure that we can fit all your demands, no matter it’s IPA, Lager, Stout, Ale... no mater it’s big breweries or small breweries, microbreweries, or even home breweries … our reusable plastic beer keg should be able to provide the best protection for your perfect beer.

none explosion plastic beer keg

There are many different type of plastic kegs on the market for beer  packaging this decades, they are light weight, cheap, no need washing/cleaning/sterilization, etc., with high barrier performance to O2 and CO2 for long shelf life, most of them for one-way use and don't need to be returned, no worry of keg lost, etc... which is quite convenient for the breweries. Most of such kegs are intent to replace the stainless steel beer keg, and actually, more and more plastic kegs are using for beer packaging on the market now, but as most of such plastic kegs are for one-way use, the unit packaging cost (packaging cost per liter beer) is still higher than the one from stainless steel kegs, and the main issue is that, some of such plastic keg is not as safe as the stainless kegs, it limite the using of such plastic kegs for the beer packaging. As have to lower the cost of such plastic keg as much as possible, so that it's competitive to the stainless steel kegs, most of such plas...

Plastic ecokeg instead of one-way plastic keg

  Based on the accidents happened in the breweries/pubs & bars recently - one-way plastic kegs explosion caused broken of hands, piecing of hands, burst of eye balls, etc... even if these are caused by some of the cheap/low quality one-way plastic kegs, not the Gprokeg non-explosion one-way plastic kegs related, and most of such accidents were paid by the insurance (the Chinese market), no loss of the manufacturers/ breweries, but some injuries will influrence the whole life of the workers, and we see the potential risk of such one-way plastic kegs for beer and/or carbonated beverages; on the other hand, the one-way plastic products will be not the direction of green/sustainable, etc... that for, from now on, Gpro Technology will stop to produce and supply the previous one-way plastic kegs. instead of the one-way plastic kegs, Gpro Technology upgraded them to a plastic ecokeg - HDPE blow molded plastic keg, with glass fiber reinforcement, which can stand over 15bar pressure, fr...
