Abstract: A net-reinforced film structure includes a film layer and a netting attached to the film layer having a pattern of netting strands. The netting strands are sealed to an opposing film structure, which may be either a similar net-reinforced film or a standard sheet of film, along a linear seal area. The netting strands in the non-sealed areas of the net-reinforced film structure are free from attachment to the opposing film structure. The netting strands along the linear seal area have a wider cross-section than the netting strands at the non-sealed areas, and this wider cross-section facilitates the sealing process.

Abstract: A mesh reinforced breathable plastic film combines the vapor permeability of breathable plastic films with the strength characteristics of mesh reinforced films. A plastic mesh layer having a netlike structure reinforces a breathable layer. The mesh reinforced breathable plastic film can be used to securely contain items that require vapor to escape during travel or storage.

Abstract: A bag or liner adapted to collect items comprises first and second thermoplastic body panels, and at least one polymeric structure. The first and second body panels are joined along a pair of opposing sides and a bottom bridging the sides so as to form an open mouth. The joined first and second body panels form an interior space for collecting items. The at least one structure is a patch, tape or pouch. The at least one structure comprises a first layer being a barrier layer and including an odor-masking and/or neutralizing agent. The first layer is attached to the bag or liner via an adhesive, a heat seal or other attaching method such that the odor-masking and/or neutralizing agent is in communication with the interior space.

Abstract: A method and apparatus for sealing a drawtape to a hem of a thermoplastic film structure is disclosed. The thermoplastic film structure includes a panel, the hem, and the drawtape. The hem is formed along one end of the panel, and the drawtape is housed within the hem. In the method, the film structure is conveyed to a stationary heat sealer that includes a stationary heated block and a hot air blower spaced from the heated block. The film structure is momentarily stopped at the stationary heat sealer with hem disposed between the heated block and the hot air blower. While the film structure is stopped, the hot air blower blows heated air onto the hem to force the hem against the heated block, thereby sealing the drawtape to the hem.

Abstract: A plastic bag comprises first and second opposing panels, a reclosable zipper, and a slider. The first and second opposing panels are fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. The reclosable zipper extends along a mouth formed opposite the bottom. The zipper includes a first track with a first profile and a second track with a second profile. The first and second profiles are releasably engageable to each other. The slider is slidably mounted to the zipper for movement between a closed position and an open position. The first and second profiles are engaged to each other while the slider is in the closed position, and the first and second profiles are disengaged from each other in response to movement of the slider from the closed position to the open position.

Abstract: Method and apparatus for the manufacture of non-roping thermoplastic draw tape handles for insertion into thermoplastic bags and in particular for the continuous application of an adhesive coated reinforcing layer of material to the handled portion of the thermoplastic draw tape to reduce roping.

Abstract: An apparatus and process to permit high speed continuous motion heat sealing in the transverse direction of a moving, multiple layer web of polyethylene film. The apparatus includes a circular drum with a heated seal bar mounted flush with its cylindrical surface. The web of film wraps around the cylindrical surface of the drum and moves at the same speed. The web is pressed against the cylindrical surface by a least one rubber nip roll and is heat sealed in the area of the seal bar. The invention is particularly adapted for presealing the ends of the drawtape in the manufacture of drawtape bags.
