    In regards to the toothpaste example previously given - don't they already have to state the volume right on the container? I realize it's not the same as pre-expected volumes, but surely the calculation is easy (vol/price).

    I know this is a somewhat naive question, but what are milk bags? Do they distribute the milk in bags rather than cartons? That's seems like a good idea and we should consider that in America as well. Packaging is a huge amount of waste. One thing I question is plastic vs recycled paper, however (bag vs carton). Although the larger sizes still use plastic.
    Milk bags are thin plastic bags, that contain milk, typically 4L comes in a plastic bag containing 3 bags, there is a plastic pitcher that is made so that a bag fits inside. This replaced the old glass jug that was heavy and needed to be transported back to the dairy for washing and sterilizing. The biggest problem being that they were heavy and fragile, not a good combination. The bags are not perfect either, when first opened they sometimes need a hand to keep them from flopping over.

    I sometimes wonder if a good way to package liquid developers, would be similar, except with a stiff cardboard outer box, to protect the bag from puncture. Add a plastic seal where you screw in an optional small tap. Open the tap to remove the contents, the plastic bag then shrinks so that no air gets inside. The cardboard and plastic are made recyclable.

    I believe that's what a standard US milk carton is today. Recycled pulp with wax or similar coating in the inside.
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    The dutch maker Amaloco sold some paper developers and fixers in a system called "cubitainer", basically what many of you know as "bag-in-a-box" from the wine shop; a mylar bag in a carton box, the content is poured out, the bag shrinks and protects the liquid.

    It wasn´t just Amaloco, another vanished brand "PAL" sold their chemistry from these cubitainers - in the early 1990s they placed them at their dealers, allowing the customer to bring their own bottles and get only what their need.

    AFAIK Peter Loeffler refrained from continuing the cubitainer when he restarted Amaloco earlier this year. But you could get your own empty b-i-b -they are sold everywhere-, fill it with your favourite brand of developer and drain it over the next months.
    Tschüss,

    Cubitaner packaging is common for Large quantities of developer see for example http://www.freestylephoto.biz/6237-C...lon?cat_id=301 (or http://tinyurl.com/n6g8l3 if that split)

    most of us don't buy our developer 19 liters at a time.

    (off topic: The trick with the milk bags is to hit the pitcher with your fist on the bottom before you cut the corner off the bag. The bag will generally slide down a couple of centimetres which makes it less floppy)

    Cubetainers were common packaging for chemicals made by Kodak way back in the 60's.

    The 3 bags for 4 liters of milk were introduced here in British Columbia several years ago with a bang. They never became very popular. You can still get them, but way more milk gets sold in 4 liter recyclable jugs.

    Anyone have a source for a 3.75 liter cubitainer (for 3/4 of a batch of Xtol - I'd like to try replenishing a 1 1/4 liter container).

    It's funny, back in Toronto pretty much everyone I knew bought their milk in the bags. Here in Nanaimo I don't think I've ever seen them! Only the 1L and 2L cartons, with 4L plastic jugs.

    Regarding an earlier post, since when does Canada not use SI units? That's all I ever learned in school! The only reason I know how big an inch is is due to photography and helping my Dad with home projects as a kid. Strangely though, I know my weight in pounds and height in feet but not in kilograms or metres.

    That´s why Amaloco came over with 5l Cubitainers.
