Abstract
Abstract Bags are dispensed from a stack of bags by locating the stack of bags on a dispensing surface and elastically pinching the stack of bags to the dispensing surface with an elastic compression means. The bags are thus capable of being removed from the stack one at a time without otherwise disrupting the stack.
