I know they're supposed to/increasingly have a recy-triangle with a number in, but it's hard to read on some packaging, and what if you only have a fragment that doesnt have the triangle on? Surely being able to say "it's a food container and it's yellow. It's HDPE" would be better, even if it meant everything in the fridge was suddenly in a blue container etc; manufacturers can use the sticky backed paper labelling to make their product stand out..

* but I'd extend it to everything]]>

Edit to add: it's good to avoid products in black-tinted plastic packaging, meat trays etc, as the machine can't see the IR colour through the black pigment. And to peel off those plastic film lids from trays and film bottle labels as they confuse the machine.]]>
