Also, the accordion bottles I have are all PE.
Yes, I will give you the plastic code once I get home tonight.
One problem I see with your squeeze bottle thing is that the cap that will come with those bottles do not make good seal. I find most developers suck oxygen with such vigor that many thin wall plastic bottles actually collapse in with negative pressure.
I've used the same jugs for developer and fixer for years. Labeled "Delta1 Datatainer." Recycle code in the triangle on the bottom is "2" and labeled HDPE plastic.

Just as an FYI, I mistakenly purchased bottles marked "5". Dektol showed degradation after about 1 months in storage. Some sediment and filament like stuff showed up and color changed to light yellow. It did work after 6 months but I didn't like the fact it showed sign of change, so I don't use them anymore.
For film, I use a 2-bath developer. This stores really well, because the developing agent and the alkali are separate. A rather amusing frustration, though is that with repeated use the first bath gets smaller and the second bath gets bigger, so no rigid bottle is ever the right size.
I'll buy the squeeze spout bottles and let you guys know about the result.
I have been using emptied and washed 2- and 4 litre wine cask bladders for at least 16 years for storage of film and print developers (including 2 part developers such as Beutler), as well as fixer concentrate. Xtol lasts at least 12 months (I've used some successfully after 18 months!).
The casks are easy to fill - remove the tap, hold the circular tap opening upright, pour in the dev. replace the tap and carefully squeeze the bladder while holding open (slightly) the tap to remove the last of the air. You can then place the bladder back into its original box (open up the top where the handles are) and reseal same with tape. Then tape a label on the front of the wine box with name of contents and date.
A 2 litre cask can hold about 3 litres, and a 4 litre holds 5 litres - great size for most larger packets of film and paper developers.

that's interesting news!
Would you have an image of the bladders you are talking about, so I can find them here in Deutschland?

Have a check at your liquor supply shop (called "bottle shops" in Australia). If you can get one, open it up and have a look at the 'bladder' and you see what I mean...hope this helps
