The customer service front desk (aka the "Inquiry") that my Dad managed at the North Vancouver, BC Kodak lab had places where large, heavy reinforced plastic bags would hang. When customers brought film in for processing, the film would be sorted as to type (Ektachrome, Kodachrome, movie film, slides, colour print film) and go into the appropriate bag. Those bags would then be regularly transported back to the appropriate parts of the lab.
Those bags were replaced from time to time. Each had big Kodak logos on them, and were appropriately yellow in colour.
As a result, at home we had one for storing certain tools, for storing shoe cleaning materials, for storing fishing gear ... (you get the idea).
Sadly the last ones were discarded as part of my parents' last move.
