RichardR9 Posted September 26, 2012 Share Posted September 26, 2012 I have had a few (5 or 6) PET bottles delaminate over the last couple of weeks. The inside seems to have peeled away from the outside. Any ideas what causes this, they are about 1 year old and have probably seen 6 or 7 brews each? Quite annoying really as I have been pretty careful with them I assume they are now unusable and I need to bin them?? Link to comment Share on other sites More sharing options...
Muddy Waters Posted September 26, 2012 Share Posted September 26, 2012 Hi Richard - I've never had that happen and I have PETs in rotation that would be years old. Sounds like maybe it is just a dud batch??? Link to comment Share on other sites More sharing options...
RichardR9 Posted September 26, 2012 Author Share Posted September 26, 2012 Hi Muddy - I did think it was odd, as I couldn't find much on this happening on the Internet. Maybe as you say a dud batch, strange that all the bottles have been fine, and suddenly a few go at once. Sounds like it's time to re-invest in some more Link to comment Share on other sites More sharing options...
Hairy Posted September 26, 2012 Share Posted September 26, 2012 I haven't had it happen either. I think in the UK they have 500ml PETs so perhaps they are made by a different manufacturer. Link to comment Share on other sites More sharing options...
RichardR9 Posted September 26, 2012 Author Share Posted September 26, 2012 They are the 500ml ones, looks like one to put down to experience Link to comment Share on other sites More sharing options...
GrahamB8 Posted September 26, 2012 Share Posted September 26, 2012 I have some delaminated 750's, quite a few actually. I used to still use them without problems. Link to comment Share on other sites More sharing options...
Muddy Waters Posted September 26, 2012 Share Posted September 26, 2012 I think you mean 740's [rightful]....pedantic? Me? Never [lol] Link to comment Share on other sites More sharing options...
PB2 Posted September 26, 2012 Share Posted September 26, 2012 They should still work okay for short term storage, assuming the inside layer is intact. Otherwise, give the DIY BEER agent in the UK a yell. Contact details are on the Brewing Products Distribution page Link to comment Share on other sites More sharing options...

RichardR9 Posted September 26, 2012 Author Share Posted September 26, 2012 Thanks PB2, I have a brew conditioning in a couple of the bottles now - so will keep an eye on them. Hopefully all will be ok [unsure] Link to comment Share on other sites More sharing options...

Otto Von Blotto Posted September 27, 2012 Share Posted September 27, 2012 Well that depends how careless you are regarding ensuring the beer is fully fermented before bottling, and adding the right amount of priming sugar. Of course infections can cause explosions too... however, I brewed for 3 years a while back, and almost a year since I started again and always used glass, never had one explode yet.[biggrin] The neighbour used to get some explosions back in the day though.

Guest Posted September 27, 2012 Share Posted September 27, 2012 On the other hand' date=' it's much harder to make a PET bottle explode.[/quote'] Beer that has been propperly fermented in clean bottles will not explode.. if you get explody bottles then it's time to have a look at your processes and get it right, regardless of what package it's in.

wilfw Posted September 27, 2012 Share Posted September 27, 2012 you know... you dont get that trouble with glass bottles [whistling On the other hand, it's much harder to make a PET bottle explode. And glass doesn't bounce anything like as well as plastic, (butter fingers?) I too have experienced this delamination but I'm sure the instructions that come with the bottles state that this does happen and will make no difference to the efficiency of the bottles. I've used mine several times and not had a problem. Link to comment Share on other sites More sharing options...
