Abstract: Double funnel bag material and method, wherein continuous length plastic film material is formed into a plurality of coextensive funnel strips connected together as formed. Each of the funnel strips is provided along an edge which is remote from the edge connection with the companion strip, with a zig-zag edge defining a series of funnel pockets therealong. The funnel strips have bag wall film attached thereto. Then after separation of the strips and bag wall material assembly along the edge connection, the strips can be rolled-up for future use, or immediately used, by forming into individual bag sections to be filled, and the bag sections separated from the respective strips.

Abstract: Material and method for making three reclosable bag sections from separable fastener equipped web, comprising folding opposite free portions of the web upon themselves and folding an intervening portion of the web upon itself and thereby providing three bag sections in a generally Y orientation. Separably interlockable fastener profiles adjacent to juncture of the three sections being arranged to provide a respective bag top separable profile fastener assembly along each of the bag sections. The bag sections are separable from one another at the juncture. Pull flanges may be provided along the separable fastener assembly of each of the sections.

Abstract: Method and apparatus for making reclosable bag material and wherein a continuous length of preformed, flat bag wall web of multibag width is continuously run along flat stationary supporting surface. A plurality of continuous length fastener profile strips are joined into corunning assembled relation with the web on the surface. The strips are guided to retain their longitudinal running positions on the web. Bonding fusion energy is applied by way of openings in the surface and through the web toward the base surface of each of the fastener strips.

Abstract: A fastener assembly has two sets of fastener profile elements for a reclosable bag especially adapted for mutually facilitating alignment and interlocking closure interengagement of said fastener profile elements responsive to closing pressure applied from outside of the bag toward the fastener assembly.Further, the fastener assembly is so constructed that a lower portion of the fastener assembly effectively resists opening separation from the interlocking interengagement thereof by separating forces exerted on the wall panels of the bag from inside of the bag body, while the upper portion of the fastener assembly is adapted to be relatively easily separated by pulling apart pull flanges extending thereabove, and such pulling apart of the pull flanges sequentially thereafter being adapted to pull apart the lower portion of the fastener assembly for access through the mouth of the bag into the interior of the bag.
