Is this a dumb idea for cone heads?

@fluketamer No Bro you are right on message

its others who invent issues with no foundation or verifiable justification but MIGHT cause a problem - naysayer

IMHO Lager may be a problem cos the average product is such thin weedy fizzy water that the slightest additional flavour might stick up your nose. Note this shouldnt apply to a traditional British Beer with it real fullsome flavour

Just look at those neat flat wine PET bottles above - fit in my pocket job - eh?

Yeah..that's PET. The box at the top is neither PET nor HDPE. As to

"food safe" BPA free

..I've had beer made in such vessels years ago.. It tasted like new-plastic, a taste I rediscovered when I first began brewing my own and used "food-grade BPA free" hoses. I quickly replaced the cheap hoses with Bevlex 200 and while I got rid of the plastic taste, I discovered what O2-permeable material tasted like and have since moved on.
Saving a buck is great, but as to a fermenter; You'll save more in not just time, effort and cash in the long run by sticking to the economical tested and true fermenters.
I heartily recommend shelling out for either a Fermzilla or a Fermonster (https://www.geterbrewed.com/fermonster-carboy-23-litres-with-tap/) ..you can always mod the fermonster later https://www.homebrewtalk.com/thread...lete-closed-transfer-system-for-cheap.680992/

Stop trying to confuse the issue with facts and experience.

I bought a 30 liter PP food plastic fruit barrel with a cap and airlock for 35 euros in an agricultural store. There is also a version with a faucet, but I don't want to use a faucet because it is difficult to keep clean, it leaks, and quite a bit of beer remains in the fermenter. If it is properly maintained (doesn't scratch the inside), I can do about fifty batch of beer in it.

PET plastic is not good for multiple use, and it also lets air in because it is not dense enough. If you try the same commercial beer from glass and plastic bottles, they do not taste the same. The one from the plastic bottle seems stale.

The world is full of PET fermenters. Oxygen permeability is very similar to PP and better than HDPE, as has already been mentioned.

Maybe we don't mean the same plastic? I'm referring to the PET plastic used to sell bottled water and juices.

"PET plastic, or polyethylene terephthalate, is a thermoplastic polymer resin and a type of polyester that's often used for packaging food and beverages"

Thing is that earlier poor experiences from 5 or more years ago have moved on since then as we became more aware of such things as BPA and O2 air spoilage etc. So I feel we should concentrate on current knowledge.
PET is well known and has its advocates. Also BPA free Polypropylene is now favoured and economically available.
Small homebrewers cant lash out on Stainless gear $$$$ and space is often limited.
So its horses for courses HFC or whatever floats your boat WFYB

Brew on baby.

There's only one PET plastic. Thickness matters for permeability of course. And it can be modified, as with the Kegland Oxebar products. FerMonsters are PET. Fermzillas are PET. Big Mouth Bubblers are PET (unless they're glass).

No plastic can be expected to last as long as stainless steel of course, but that's a whole different conversation. The most important thing with any plastic fermenter IMO is to avoid scratching the inside when cleaning, as this will give infections a place to hide.
