A bag has wall panels defining a receptacle space and providing a bag mouth arrangement between upper end portions of the wall panels. A tamper evident, and if desired hermetic seal, non-reclosable closure adjacent to a reclosable zipper and located adjacently below upper end portions of the wall panels is accessible to be opened when the zipper is open. The zipper is arranged for intermittent opening and closing of the bag and its opposite ends are sealed into the side edges of the bag. The non-reclosable closure may be a peel seal or a rupturable connection.

A chain of plastic bags having zipper-locking profiles is packaged in a rectangular carton in successive layers wherein the profiles of the bags of each layer are aligned generally along a straight line that is oblique with respect to a front wall of the carton, the straight lines aligning the profiles of successive layers following a zigzag course, which oscillates between the front wall and a back wall of the carton.

Thermoplastic film bag making material is processed between a hotseal jaw and cutoff knife assembly. The apparatus has complementary first and second jaws between which the material is received for sealing bag side edge areas of the bag making material. The first jaw has a groove and the second jaw has a cutoff knife for extension into the groove for separating the material into individual bags. A rubber anvil block is in a groove underlying a zipper of the bag material and the knife thrusts into the block and attains substantially straight edges in the bag cutoff. Improved end sealing of the zipper also results.

A method of making reclosable bag material and bags made therefrom, wherein the bag making film providing bag walls is provided with an extruded plastic profile reclosable fastener strip across a portion of the longitudinal formation axis of the film and bag walls to be located at the open end of the bag and the strip having a base web for attachment to the film, and bonding the base web of the fastener strip to the film so that on one wall of the bag the base web is attached above and below the profile structure on the strip and on the other wall of the bag the base web is bonded to the film at a location only above the centerline of the profile structure on the strip.

A method and apparatus for making reclosable bag material wherein a film has a longitudinal formation axis extending the length of a bag to be made therefrom and the film is incrementally advanced longitudinally, strips of extruded plastic profiled reclosable fastener strip are movable laterally axially across the film for location at one end of a bag made from the film with the profiles projecting in a direction toward the film, the strip is rotated to have the profiles facing away from the film and a strip base placed on the film and the base heat bonded to the film.

A reclosable plastic film for a bag and the method and mechanism for making the same. The film may be employed for making various types of bags, but in each case the arrangement provides for a tear strip wherein a series of perforations are placed in the film extending parallel to the fastener profiles, and a sealing cap layer is placed over the perforations which cap layer is grain oriented and sufficiently frangible so that as the film is torn along the line of perforations, the cap layer will tear, providing sealing until tearing occurs. A method and apparatus are provided wherein a completed film for a bag may be constructed in a single pass with the film first being perforated, the cap layer laid over the film while molten, and the profiles then attached to the film oriented relative to the location of the perforations.

A method and apparatus for forming bags such as in a form, fill and seal machine wherein the bags are formed by drawing film downwardly over a filling tube and cross-sealing the bag tube and applying a lateral stretching force to the bag tube at the location of cross-sealing preventing wrinkles at the location of the seam formed by the cross-sealing with the stretching force applied at the extreme lateral edge of the film preferably by opposed cam surfaces at each of the bag edge which contact each other at a point just outside of the bag edges and progressively walk into the edge of the bag with the point of contact shifting in an outward direction while it progresses inwardly on the bag to apply a stretching force to the film of the bag for smoothing the entire width.

A tray for foodstuffs or the like having a continuous edge rim and a flexible cover placed over the top of the tray and sealed to the rim with an elongate continuous interlockable separate rib and groove profile on strips sealed to the surface of the cover wherein upstanding pull flanges above the rib and groove profiles may be pulled apart and the cover severed between the profiles for access to the contents so that the cover may be opened and closed.
