A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.

A packaging bag has a bag body formed from a flat web and has a first front wall and a second front wall as well as a stand-up bottom formed in a bottom section by folding and gluing the front walls. The flat web has a varnish coating on an outside of the bag body, wherein the first front wall has an adhesive region free of the varnish coating in the bottom section of the bag body.

The present invention relates to a band (1) that can be stored in reel format, which has areas coated by a thermally-activatable adhesive material (2) following a coating pattern (3) that is repeated along the band with at least two main transversal strips (5a, 5b) that extend between two longitudinal edges (1c) of the band and that include areas (21) coated with a grammage of thermally-activatable adhesive material between 35 and 130 gr/m.sup.2. A specific use of the band (1) is for making mesh bags (10) and in particular to close a portion of a tubular mesh (11) by interleaving said mesh portion between two coinciding portions of the same or of two bands (1, 1) and with respective main transversal strips (5a, 5a) of the coating pattern (3) towards the mesh; applying pressure; and providing heat.

A side gusset paper container in which in the region of the transition of the front wall to a first part of the container bottom region, there is a first pre-crease, and in which in the region of the transition of the rear wall into a second part of the container bottom region, there is a second pre-crease. Furthermore, the disclosure relates to a method for producing a side gusset paper container, in which at least one or a plurality of linear pre-creases are formed in the inner side of a paper web. Additionally, the disclosure relates to a use of the side gusset paper container according to the disclosure as a compost collecting and/or carrying container and/or as a fillable container which is self-standing in the unfilled state.

A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

A protective product, such as, e.g., an envelope or pouch, is provided that includes at least one expanded slit paper sheet in an expanded state, and an embossed paper sheet facing the expanded slit paper sheet and fixed to the expanded slit paper sheet along at least a portion of a length in an expansion direction of the expanded slit sheet paper. In the preferred embodiments, the embossed paper sheet has a plurality of embossings that increase the rigidity of the embossed paper sheet, thereby inhibiting deformation of the embossed paper sheet that is fixed to the expanded slit sheet paper.

A method for manufacturing a sheet material container where the sheet material container includes one or a plurality of sheet members including a main-body forming sheet member that has an outer film layer and an inner film layer which are mutually stacked, a containing region that accommodates contents, and a container body that is configured from the main-body forming sheet member and that surrounds the containing region, and the main-body forming sheet member having a main-body sealing portion, which is an attached region between the outer film layer and the inner film layer, and a non-attached region where the outer film layer and the inner film layer are partially not attached, and further having a filling portion where a filler is enclosed between the layers of the outer film layer and the inner film layer in the non-attached region.

One or more implementations of a thermoplastic bag with a grab zone of deformations including raised rib-like elements positioned in a high-touch area of the bag. For example, the thermoplastic bag includes a hem skirt non-continuously laminated to a sidewall by one or more raised rib-like elements. The grab zone regions of one or more raised-rib-like elements are located in visible and high-touch areas to provide visual and tactile cues of strength and durability. Moreover, the grab zone regions of one or more raised rib-like elements serve to distribute pull and lift forces across a wider area in order to avoid common failures in high-touch areas such as over stretching, punctures, tears, and rips.

According to some illustrative embodiments, a protective product is provided that includes: at least one expandable slit paper sheet, said at least on expandable slit paper being expanded between opposing ends of said slit paper; a first embossed paper sheet facing said expanded slit paper sheet and a second paper sheet facing an opposite side of said at least one expanded slit paper sheet, at least one of said first embossed paper sheet and said second paper sheet being fixed to said expanded slit paper sheet at the opposing ends of said expanded slit paper sheet and thereby maintaining said expanded paper in its expanded state, said first embossed paper sheet having a plurality of embossings that increase the rigidity of said embossed paper sheet, whereby inhibiting deformation of said embossed paper sheet that is fixed to said expanded slit sheet paper.

A flexible package having an inner sheet having a first surface and a second surface. The flexible package has an article reservoir for accepting an article to be shipped and one or more expansion chambers. The expansion chambers can be inflated or otherwise expanded to provide structure to the flexible package and to protect the article in the article reservoir.
