An industry on my layout is going to be Luetzow on Badger Siding on Davis Avenue in South Milwaukee on the UP, formerly the C&NW.
Mark “Fuzzy” Hintz has current photos and informtion about this siding on his very large website

Mark quotes an earlier post of mine where I see I spelled Luetzow wrong.
The company started as a dry cleaner but developed its own plastic bags for dry cleaning and converted entirely into a manufacturer of plastic bags. They get plastic pellets (about the size of aspirin) in ACF CenterFlo covered hoppers. These days they get two such cars at a time.
What makes this particular industry useful for a model railroader is that the unloading device and tubes are across the street from the factory itself, so in a tight spot you could simply omit the building and just have the cars and the unloading devices.
What was driving me a little nuts is that while I have photos of what the building looks like now, my recollection of what it looked like circa 1967-69 when I model the Chicago & North Western is decidedly hazy. And here is where the internet is so great … Luetzow has a website
http://www.eluetzow.com/index.shtml
and fortunately for me, they include a page of historic photos including what it looked like in the late 1950s which is exactly what I [now] recall it still looked like in 1967
