Abstract: A method for making a film bag with reinforced bag seams includes a film extruder that produces a continuous tube of film. A flattener produces a continuous web of flattened film which has an upper surface and a lower surface. A fold maker has a receiving portion positioned above the web and a displacing portion is positioned below the web that moves cyclically upward to a first position to locate a portion of the web into the receiving portion, thereby forming a fold. A fold retention device prevents the fold from opening. A presser flattens the fold against the web. A sealer seals through the fold, forming a reinforced bag seam. A cutter severs a sealed portion from an unsealed portion of the web. A transport mechanism moves the film from the extruder, through the flattener, into the fold maker, beneath the presser, into the sealer and to the cutter.

Abstract: A self-opening bag includes front and real walls joined at their respective first and second side and bottom edges. The bag is folded at least once parallel to its side edges. At least one attaching feature is located on the outer surface of the bag adjacent the upper end and between the folded walls. The bag is releasably attached to a subsequent bag. The at least one attaching feature causes the bag to open as the bag is pulled from the subsequent bag. The once folded bag may be sealed at the bottom edges after folding to form a star-sealed bag bottom. The bags may be removably attached to each other at a perforation line and wound onto a compact roll for use with a bag dispenser. The bags may have an upper seam, a U-shaped cut and a pair of bag handles. The bags may be corona treated.

Abstract: A core pin bag dispenser includes a planar base sized and shaped to fit beneath a roll of film bags. First and second upwardly extending rods are mounted to the base. A retaining pin is sized and shaped to fit slidably within a hollow core of the bag roll. The pin has first and second orthogonal apertures located adjacent the first and second ends that are spaced apart by at least a width of the roll of film bags and are sized and shaped to fit slidably over the first and second upwardly extending rods. An upward pointing snagging hook is mounted adjacent a front edge of the base and is sized and shaped to engage either a chisel cut or a perforation in the bags. Two of the dispensers are mounted to an adapter designed to fit into the side channels of a bin mounted to a vertical surface.

The support stand is pivotally mounted to an underside of the structure and optionally is securable in either a first, upper position or a second, lower position. A latch prevents unwanted removal of the dispenser from the rack. Two or more structures may be attached to the support stand, thereby providing a choice of bags. Openings are provided in the rack to provide visual access to outer surfaces of the dispenser.

Abstract: An apparatus for corona treating film includes a source of film material and at least one transport roller that is rotatably mounted in a frame. The transport roller has a longitudinal axis and has a width greater than the film. First and second treater heads have first and second leading edges, first and second trailing edges and are mounted parallel to the longitudinal axis. The second leading edge is parallel to and spaced from the first trailing edge by a second predetermined distance. The film is transported over the roller and a high voltage electric arc is provided to the first and second treater heads. The roller is grounded and provides a return path for the electric current provided to the first and second treater heads, thereby corona treating the front side or back side of the film if a second roller and third and fourth treater heads are used.

Abstract: A clamshell dispenser for film bags includes a planar base shaped to fit beneath a bag roll. Side travel limiters are attached to the base. A retaining bracket is hingedly mounted adjacent a front edge of the base to prevent the roll from moving outwardly from the dispenser when the bracket is latched. The bracket opens for introduction of the roll. An upward facing snagging hook engages either a chisel cut or a perforation in bags from the roll. A downward facing snagging hook may be attached to the retaining bracket. An adapter for a bin includes first and second bag dispensers mounted to a fixture. The fixture is shaped to fit within the bin. First and second axles are orthogonally attached to the fixture. The axles mount first and second positioning wheels that are located to slidably engage first and second integral channels in vertical sides of the bin.
