Baloney. Reagent bottles are commonly made from glass. Hydrofluoric acid etches glass and therefore requires a polystyrene or fluorocarbon container. The beer foam head would be visible through the glass. HF also like to creep out of bottles and corrode any metal in the fridge. It's normally stored in multi-layer containers with some very large and specific labeling requirements. Anyone with experience handling chemicals knows that it's not likely to be stored in a mislabeled and unprotected glass reagent bottle.

Also, I'm told that alcoholic beverages in plastic bottles tastes rather horrible. The usual screwup is to use the same PET (polyethylene terephthalate) bottles as various soft drinks. PET is good for keeping CO2 inside the plastic bottle, but not so good at keeping oxygen from getting into your beer and making it taste disgustingly stale: That's also one reason why beer isn't sold in plastic bottles.

What will we do when we run out of TLA's?

the used to be be some beers in plastic here, it was PEN instead of PET and best before was only 3 months compared to the usual 9 month

You must surely have known I was just joking!!

It's difficult for me to determine. I usually give everyone the benefit of the doubt. I assume that they are serious and not wasting my time. However, for your benefit and to avoid my making the same mistake twice, I'll assume that everything that you write is hogwash, unless you clearly demonstrate with references, URL's, citations, quotes, calculations and examples that you are worthy of being taken seriously.

I am the wizard of news. I sometimes tend to confuse. But if you can't wait, I'll trim the debate. The end is always - you lose.

PEN is Polyethylene naphthalate "Because it provides a very good oxygen barrier, it is well-suited for bottling beverages that are susceptible to oxidation, such as beer."

"PEN, a cousin of PET, typically delivers a five-fold improvement in both CO2 and O2 barrier versus monolayer PET, along with higher heat resistance and good clarity. PEN has a Tg of 122 C, far exceeding that for PET, so PEN blends would allow mono layer bottles to be pasteurized. The high price of PEN and PEN/PET blends currently prevents widespread adoption for single-use containers. But sources at BP Amoco in Naper ville, Ill., which makes the key monomer for PEN, says monolayer PEN bottles are making inroads into multi-trip refillable beer and water bottles in Europe and Brazil."

Naphthalate-based bottles beckon

Most of the articles I found were from around 1995-96. Then, nothing. I wonder what happened. PEN costs 4 to 5 times as much as PET which might have killed PEN.

Interesting and thanks.

I just looked it up, they were used here from 1999 to around 2007 people were buying cans instead

How? You post nonsense more or less non-stop. How are we supposed to be able to distinguish between the nonsense you claim to have been aware was nonsense and the nonsense which reflects your sincere (if woefully ill-informed) beliefs?

That's the failsafe approach everyone here should take to anything I post. I thoroughly recommend it. :-D

Methinks you take the easy route. Leaving me with little doubt. What you recommend, is this will now end, as garbage in and garbage out.

Doesn't that get pretty boring?

"I don't like change" means "If they held a referendum on making blacks and women property again I'd be out the door to vote yes on it in 5 sec"

Well spotted, sir!

Conservative don't like anything very much. Apart of course from whingeing and bleating on about immigration, brexit, Johnny foreigner, taking back control, the remoaners, Boris is a very clever man, that communist Corbyn, blah blah, etc. etc. They are excruciatingly BORING!
