A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.

The present disclosure relates to an apparatus and method for manufacturing spouted pouch containers. The method includes arranging an upper and lower strip with their inner sides on top of each other, folding at least one longitudinal edge of the upper strip away from the lower strip to expose both an inner side portion of the folded longitudinal edge of the upper strip and an inner side portion of the lower strip, arranging a spouted cover strip on top of the exposed inner side portions, sealing pairs of side walls of the upper and lower strip to each other and sealing the spouted cover strip to the exposed inner side portion of the lower and upper strips, and cutting the upper strip and lower strip into individual pouch containers. The apparatus is provided for carrying out the manufacturing method.

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).

Fiber-based composite material for padded mailers and corresponding systems and methods are provided herein. A fiber-based composite includes a fiber-based backing material and a fiber-based padding attached to the backing material to provide cushioning for items within a mailer. The fiber-based padding is applied as a plurality of tubular structures, each defining a perimeter extending from a first point of attachment to a second point of attachment. The perimeter further defines an apex point which is spaced apart both laterally and vertically from a center point on the backing material that is between the first and second points of attachment. A plane connecting the center point and the apex point defines an angle with the backing material that is greater than 5 degrees and less than 75 degrees.

The present invention relates to improvements for shopping and merchandise bags with integral handles. Disclosed is a bag with integral handles and closure elements located below the integral handles. Further disclosed is a process for manufacturing a reclosable bag with integral handles. The handles and bag may be formed from a wave-cut polymeric tube. In addition, the handles of the bag may be formed from a wave-cut polymeric tube while the body of the bag is formed from a side-gusseted polymeric tube. The disclosed bags and methods to make such bags provide cost effective solutions for providing reclosable bags with integral handles.

A packaging material includes a web of pouches and an outer skin. One panel of the web has an inflation pattern that is not inflated. The web has a continuous inflation channel that is in fluid communication with the inflation pattern. Each of the pouches of the web can be inflated by inflating the inflation pattern while the outer skin already attached to the outside of the web. The outer skin is attached to the web only along edge lines of the pouches. The outer skin is detached from the web between the edge lines of the pouches. The outer skin is attached to the outside of the web such that the continuous inflation pattern extends above the outer skin.

A recloseable package is provided having a recloseable fastener assembly positioned on an inside surface of a front wall of the package. An openable region defined by the front wall of the package provides access to the recloseable fastener assembly and the package contents. The openable region typically comprises perforations or scoring. In order to facilitate such access during initial opening of the package by separation of profile strips of the fastener assembly, an access opening defined by the front wall of the package is provided at the openable region. At least one of the profile strips of the fastener assembly can be provided with a stand-off projection, which can be accessed through openable region. The projection desirably acts to separate the profile strips of the fastener assembly, to facilitate gripping and manipulation of the fastener assembly to facilitate its convenient use. Notably, this projection can be configured be deformable, to facilitate manipulation and separation of the profile strips of the fastener assembly. Additionally, a free edge portion of one of the profile strips can be colored so that the free edge portion is readily visually discernible through the access opening. Convenient opening of the openable region is thus facilitated.
