Abstract
A serially interconnected chain of reclosable, zipper-lock plastic bags is arranged for facilitated handling in an automatic bag filling machine. The bag chain may be formed with single or plural connecting spot links between side edges of adjacent bags to maintain alignment of the bags in the chain as the chain is unwound from storage and threaded along a lateral transport path running through the filling machine. The connecting links are adapted to be broken during the loading operation so that separate, loaded bags may be discharged from the machine for packaging. Each bag is formed with raised ridge surface means running laterally thereacross adapted to be slidably received in a suitable guide track means of the filling machine to provide vertical support for the bags as the chain is being drawn between various work stations in the filling machine.
