An oral tobacco pouch product includes a pouch wrapper formed of a web having a longitudinal integrated fin and lap seal. The pouch wrapper contains a filling material including tobacco material and optional additives. The longitudinal integrated fin and lap seal is formed on a forming collar.

The present invention is directed to tamper-evident mesh material, methods of manufacture therefor, and tamper-evident bags manufactured therefrom. The tamper-evident mesh material of the present invention may be used, for example, in the manufacture of a variety of tamper-evident security bags for use in applications where it is desirable to detect any traces or evidence of tampering with or of unauthorized access to the contents of the bag.

A reinforced multilayer material includes a mesh material covered on at least one side, and possibly both, by a layer of a resinous film material. The mesh material includes filaments that intersect one another, at least some of the filaments being composite filaments having a carrier portion of a relatively high melting point and a bonding portion of a relatively low melting point, the bonding portion of each composite filament being thermally bonded to other filaments at least some points of intersection. The multilayer material has a mass per unit area of less than 9.0 oz/yd.sup.2 and at least one of a) a bursting strength to mass per unit area ratio of at least 9.0 lbs./(oz/yd.sup.2), where bursting strength is measured in accordance with ASTM-D37 86 and b) a breaking elongation of at least 5% in the warp direction when breaking elongation is measured in accordance with ASTM-5034. A bag is provided that is made at least in part from a multilayer material having at least some of the characteristics described above.

A packaging bag has a bag body on a paper basis, which has front walls that lie opposite one another, side walls arranged between the front walls, and longitudinal edges that connect the front walls with the side walls. A material section that forms the assigned front wall and a material section that forms the assigned side wall, are connected with one another on the longitudinal edges to form a reinforcement fold that runs in the longitudinal direction, by way of a fixation layer that borders on each longitudinal edge. The fixation layer assigned to at least one of the reinforcement folds is an adhesive layer, wherein regions of the bag body between the reinforcement folds are free of an adhesive layer.

Bags for containing various retail items, such as food items, and methods of forming the same. In some aspects, a bag having a top and bottom is provided. The bags can include a first layer and a second layer opposite the first layer and uniformly extending from the first layer. In some aspects, the bag can further include a first side seam between a side of the first layer and an opposing side of the second layer and a second side seam between a side of the second layer and an opposing side of the second layer. The first layer and the second layer each have an un-folded edge substantially parallel to the bottom fold. In some aspects, the bags include a bottom V-shaped fold extending along a transverse axis relative to the first side seam and the second side seam, the bottom V-shaped fold forming a seamless bottom.

A bag has a front panel, a back panel, and a gusset, each having a thermoplastic ply at its interior face. The interior face of the gusset is thermally welded to the interior face of the front panel and back panel at respective joins from which extend respective panel extensions which are also thermally welded to each other at a third join. Extensions of the gusset cover parts of the respective panels and are thermally welded to them. Other parts of the panel extensions are not covered by the gusset extensions and are welded to each other to form the third join. The extensions can form a handle part for the bag.

A woven laminated plastic bag having an easy open feature is provided. The easy open feature is generally defined by a weakened portion in the bag. In various aspects the bag can be fabricated from a woven polyethylene layer which can be laminated with a polyethylene film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.

A flexible pouch for containing a product. The flexible pouch may include a pouch body formed from an opaque multilayer panel configured to protect the product contained in the flexible pouch from oxygen ingress into the flexible pouch. A gusset formed from a multilayer panel comprising an opaque portion and a transparent window portion may also be included, and the transparent window portion allows for configured for viewing the product within the flexible pouch.

A kraft sack is disclosed for products to be packed and stored in dust and granule forms such as chemical, food, mine, construction and building industry products. The kraft sack was manufactured to prevent from possible odour transition and humidity creation from and into package inside and outside of dust and granule raw materials, and provides protection thereof in order to maintain physical and chemical features of product against interior and exterior factors, against dusting that could occur during evacuation of air through perforation holes over kraft sacks during process of filling the kraft sack.

A woven laminated plastic bag having features that further prevent leakage of contents out of the bag, or infestation of organisms into the contents of the bag is provided. In various aspects the bag can be fabricated from woven polypropylene and/or polyethylene layer which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing. The bag can also include a tape covered easy open feature that facilitates removal of tightly adhered sealing tape.
