Abstract: The present invention relates to improvements for the manufacturing of a wave-cut bag of polymeric film, more specifically a wave-cut bag with a body having improved shock, tear and puncture resistance. The polymeric film has an embossed pattern of a plurality of embossed regions that are comprised of a plurality of parallel, linear embosses. Further disclosed is a process for intermittently applying the embossed pattern to a collapsed tube of a blown film extrusion process. The collapsed tube with the intermittently applied embossed pattern is particularly well suited for constructing wave-cut trash bags with the embossed pattern applied to a central body of the wave-cut bags.

Abstract: The present invention is directed to a method and apparatus for securely applying print to a web of continuous polymeric film. The web can first travel in a machine direction on a tensioning roller and onto a folding board whereupon the web is divided into first and second partial widths with a cross-section of the web taking on a U-shape or a V-shape. In between the cross-section of these two partial widths a printer can be placed such that the printer prints onto an inner surface of first partial width. Once the printing is complete, the folding of the web can be completed such that an inner surface of the second partial width is in contact with, covers, and protects the printed matter placed onto the first partial width.

Abstract: The present invention relates to polymeric bags, particularly polymeric drawstring trash bags. The present invention comprises a trash bag having an elastic drawstring. The elastic drawstring trash bag features an integrated short seal comprising an inner seal, an outer seal, and an intermediate seal. The integrated short seal functions to reduce the upper opening of the drawstring trash bag, while the elastic drawstring utilized with the bag provides a bag that allows the bag to fit snugly on many common trash receptacles.

Abstract: The present invention is directed to a method of incrementally stretching polymeric film formed from a blown film extrusion process. The present invention is further directed to a polymeric bag formed from an incrementally stretched polymeric film. The incremental stretching is performed on a collapsed polymeric bubble via a pair of intermeshing rollers. The incrementally stretched polymeric film may be stretched only along a portion of its width. The polymeric bag may be a drawstring trash bag with an extended hem where only the extended hem of the bag or the body of the bag comprises incrementally stretched polymeric film.

Abstract: The present invention is directed to a thermoplastic bag comprised of a front panel and a back panel. The front panel and back panel are generally joined along a first side edge, a second side edge, and a bottom edge of the respective front panel and back panel. The front panel has a distal edge with the distal edge folded over the front panel to provide a hem and an overlap area immediately below the first hem. The overlap encapsulates a scent carrier that can provide a scent to the thermoplastic bag.

Abstract: The present invention relates to improvements for T-shirt bags formed from a side gusseted tube of polymeric film. In particular, the embodiments of the invention provide means for reinforcing the handle seals of a T-shirt bag while limiting the amount of scrap material generated in the manufacturing process. In one embodiment, at least two seals are provided for forming each of the opposing two handles of the T-shirt bag. In further embodiments, a curved lower seal is provided as part of each handle's seal. In additional embodiments, a single seal of a continuous area is provided for each handle.
