The present invention is directed to a bag of polymeric film and a method to make the bag. The bag can be comprised of a front panel and a rear panel. The front and rear panels can each be comprised of multiple layers of film. The bag can be formed from a collapsed bubble of polymeric film that has been folded in half so that opposing edges of the collapsed bubble form an opening of the bag. One of the layers of the folded bubble can be split adjacent to an edge of the collapsed bubble and a draw tape film can be inserted between the layers of the folded and collapsed bubble. The collapsed bubble can further be embossed by a pattern that can provide enhanced properties to bags formed from the folded bubble.

Continuous method for making a web of draw strip bags, comprising providing a film web (F) wherein a first portion (11) and a second portion (12) overlap each other with free longitudinal side edges (7, 7′) thereof being essentially aligned with each other, back folding a first part (13) having said free side edge (7) of the first portion (11) outwardly away from said second portion (12) along a first fold line (B) by a first hemmer (120), and by folding a first subpart (15) of said first part (13) along a second fold line (C) whereby the free side edge (7) of the first portion (11) is brought into near alignment with said first fold line (B) while a second subpart (14) of said first part (13) of the first portion (11) remains back folded, whereby said first and second subparts (14, 15) of the first portion define a first hem (H1).

Improvements to asynchronous spatial listen before talk (LBT) procedures are disclosed. In a shared spectrum network spatial LBT procedures are used for directionally targeting the channel reservation process. Prior to transmitting channel reservation signaling, the transmitter and receiver determine an effective interference considering available multiple input, multiple output (MIMO) configuration information. When the effective interference exceeds a predefined threshold, the node may without transmission of its channel reservation signal. Otherwise, when the effective interference remains within the threshold, each node's transmitted channel reservation signal may also identify at least a beamforming matrix either as payload or used to precode the node's channel reservation signal.

A method and apparatus for making bags or pouches is disclosed. An ultrasonic sealer may be used to form the seals. Sealing patterns may be used to provide a desired strength profile.

The present disclosure relates to strata 2-ply drawstring trash bags implementing a J-flap extended hem to provide increased top-of-bag strength. In one or more embodiments, the J-flap extended hem includes a 2-ply web folded back on itself (e.g., during a hem folding operation to enclose the drawstring within a hem channel). In one or more implementations, a hem seal secures the 2-ply web to an inside surface of the trash bag. At least one ply of the 2-ply web fold-over extends past the hem seal and is additionally secured to the inside surface of the trash bag via one or more hem skirt seals. For reduced material consumption in certain embodiments, the J-flap extended hem of the present disclosure imparts added strength using only one ply of the 2-ply web fold-over. In some embodiments, at least one ply of the 2-ply web fold-over includes ring-rolled portions to add top-of-bag strength.

A storage bag comprising a floor, the floor having four corners and edges, the four corners defining a planar surface; a pair of opposing triangular interstitial regions, each triangular interstitial region having a vertex, two sides, and a base, the base of the triangle co-linear with one edge of the floor; a gusset, the gusset bisecting the floor region and both opposing interstitial regions, the gusset co-linear with the vertex of both of triangular interstitial regions; a pair of opposing body regions, the lower edge of each opposing body regions co-linear with two corners of the floor region; and, an opening, the corners of the opening forming an imaginary plane, wherein the planar surface formed by the corners of the floor region and the imaginary plane formed by the opening of the body region are in parallel planes after the storage bag is opened for use.
