Abstract
Abstract A pad of plastic bags comprising a plurality of bag units, one above the other, each unit comprising a pair of oppositely disposed open-mouthed pockets connected to a common spacer portion by score lines or the like at the mouth ends of the pockets, each pocket having a lip at its mouth end spaced from the respective score line, the multiple bag units being connected to each other at the spacer portions by a weld or other connection at each side of the spacer portions, the connected spacer portions forming a base for all the bag units in the pad, the side welds acting as an anchor means to resist the forward pull on the lip as a bag is torn away by grasping the lip and pulling forward, whereby the bag is substantially fully opened and severed from the base at the same time.
