i operate a tandem inline extrusion coating machine. it's 178ft long and has two coating heads. we make flexible packaging, medical products (all 3m surgical drape used in the world is produced on my machine, just in case you were nervous about surgery before!), and food packaging. the rolls come off my machine as jumbo's, anywhere from 1500 to 6000 lbs, and get shipped directly or slit for customers in house. i snagged some pics last night before i left, we were running cosmetic web, which can be used for anything like ketchup to toothpaste to travel shampoo packets.
