A recyclable composite zipper bag and a method for producing the same are provided. At least two side edges of two composite films are bonded by heat seal to form the bag body of the recyclable composite zipper bag. Each composite film includes an outer layer and an inner layer. The outer layer is a BOPE film and the inner layer is a PCR PE film. The outer layer and the inner layer are combined with each other. The composite film made of BOPE and PCR PE can increase impact and puncture resistance of the recyclable composite zipper bag and favor to recycle and reuse. In the method for producing a recyclable composite zipper bag, the composite films are bonded by heat seal at a temperature of 120-130° C. in order to effectively avoid wrinkling, thereby improving the yield of products.

A storage bag includes first and second side surfaces that form an interior of the bag with an opening to the interior. A first closure profile connected to the first side surface and positioned adjacent to the opening has a top edge and includes an interlocking member that extends between first and second sides of the first closure profile forms a lip between the interlocking member and the top edge. A second closure profile connected to the second side surface and positioned adjacent to the opening of the bag has a top edge and includes an interlocking member. A first portion of the lip of the second closure profile smoothly transitions into a third portion of the lip of the second closure profile, and the third portion of the lip of the second closure profile smoothly transitions into a second portion of the lip of the second closure profile.

A slider garage includes an overmolded body, the overmolded body oriented on a zipper, the overmolded body including an overmolded male portion and an overmolded female portion, the overmolded male and female portions positioned on an end of the zipper, such that each is on one side of the zipper, the overmolded male portion being shaped such that it fits in the overmolded female portion in a watertight fashion and the overmolded body is molded over a portion of the zipper.

An anti-theft delivery bag includes a bag having a front side and a rear side, the front side having an opening providing access to an interior portion of the bag. A fastener mechanism is positioned along the opening, the fastener mechanism configured to alternate between an opened position providing access to the interior portion, and a closed position preventing access to the interior portion. A locking device is configured to lock the fastener mechanism in the closed position. A strap is configured to be positioned on a door handle. A configurable latch member is attached to the rear side of the bag. The latch member includes a rectangular frame configured to be positioned against a mortise plate within a door jamb of a door, such that the latch member and the anti-theft delivery bag are secured in position when the door is closed and locked preventing theft of the bag.

A thermoplastic bag includes raised rib-like elements that allow the thermoplastic bag to expand. The thermoplastic bag further includes side seals having rib-like elements that allow the side seals to expand. Additionally, in one or more implementations, the thermoplastic bag includes one or more of a material formulation, a density of raised rib-like elements, a height of raised rib-like elements, or land areas that provide the raised rib-like elements with a reduced rebound ratio.

A zipper for a reclosable bag including an elongated groove profile having two arms which form a general U-shape to define an opening to a channel, and an elongated rib profile opposing the groove profile, wherein a plurality of first segments of the rib profile alternate with a plurality of second segments of the rib profile to create a structural discontinuity along a length thereof, wherein during interlocking the groove and rib profiles, an audible clicking sound of at least 50 dB on average is created during opening and closing.

A storage bag has first and second closure profiles adjacent to an opening of the bag. The first and second closure profiles are each provided with a closure member that extends along the length of the respective closure profile, with the closure member of the first closure profile being configured to engage with the closure member of the second closure profile to form a seal for the opening of the bag. The first closure profile further includes (a) a plurality of gripping ridges that extends from the closure member to the top edge of the first closure profile, and (b) a texture that extends in an area between the closure member and the top edge of the first closure profile, with the texture extending continuously (i) in the area between the closure member and the top edge of the first closure profile, and (ii) between each gripping ridge of the plurality of gripping ridges.

In order to allow a bag to be easily unsealed by sliding both sides of the bag in a longitudinal direction of a zipper tape irrespective of the rigidity of the zipper tape, a zipper-tape bag according to an aspect of the invention includes: a bag body including at least a pair of facing surfaces; and an elongated zipper tape whose cross sectional profile includes first and second bases each bonded to corresponding one of facing surfaces, and mutually engageable first and second engagement portion respectively protruded from the first and second bases, the zipper tape including an intermediate hinge at at least one point in the longitudinal direction.

Provided is a process for preparing a zipper pouch, wherein the process comprises: A) forming a first laminate by a process comprising i) bringing together a polyisocyanate component and a polyol component to form an adhesive composition, ii) applying a layer of the adhesive composition to a layer of polyethylene terephthalate, iii) then contacting the layer of the adhesive composition with a layer of polyethylene having thickness of 80 micrometer or more; B) contacting a polymeric zipper construction to the first laminate at temperature of 200 C or higher. Also provided is a zipper pouch made by that process.
