Abstract: During the manufacturing process the exterior surface of one or both of the sheets of plastic film which form the bags is treated with low temperature corona discharge plasma to raise the level of surface charge magnitude to at least 43 Dyne to increase the adhesion force between the bags. A recess is formed in each of the bags to further increase the adhesion. The increased adhesion causes the mouth of one bag to automatically open as the adjacent bag is removed from the rack. The recess is formed at the same time openings are created in the bags to accept the support rods of a dispensing rack. The bags can have simple edge sides or side gussets and may be provided in a package including a pouch which receives and supports the lower portions of the bags.

Abstract: A method of packaging point-of-purchase items involves supplying plastic bags as a continuously attached length of bags, each bag being separated from adjacent bags along the supply length by a perforated tear line. The length of bags is stored on a storage form or in another suitable manner permitting advancement of bags when pulled out of the stored condition. The perforated tear line cuts entirely through the web of bags. However, the perforation along one side of each bag is broken to present an open flap through which contents can be added to the bag prior to removal from the web. The method of using the bags for packaging produce, groceries or other articles generally selected at point of sale and which are generally segregated by type for later pricing by weight or unit, permits a user to at least partially fill a bag prior to removal from the web.

Abstract: A plastic bag is supplied as a continuously attached length of plural bags, each bag being separated from adjacent bags along a supply length by a perforated tear line. A seal which runs codirectionally with the tear line forms a closed bottom for each bag, such that when a bag is separated along the tear line from a remainder of the supply, the bag is enclosed along three of its four edges enabling containment of produce or other items placed therein via the opening at the fourth, and remaining edge of the bag which is coextensive with the perforation line. The supply length of bags is advantageously stored on a roll, fan folded, bundled or compactly stored in other suitable manner permitting advancement of consecutive bags when pulled out of the stored condition by a user.

Abstract: A web of pre-opened plastic bags is supplied as a continuously attached length on a storage form, each bag being separated from adjacent bags along a supply length by a perforated tear line. A seal which runs codirectionally with the tear line forms a closed bottom for each bag. The supply length of bags is advantageously stored on the storage form to permit advancement of consecutive bags when pulled out of the stored condition by a user. The perforation tear line cuts entirely through the continuous web supply of bags, however, the perforation along one side the bag is broken, such that the bag presents an open flap through which contents can be added to each bag prior to its removal from the remainder of the continuous bag supply. The storage form provides tension against the dispensing of bags.
