One or more implementations of a multi-film thermoplastic structure include a first film having a first appearance in contact with a second film having a second appearance at one or more visually-distinct contact areas. Wherein the one or more visually-distinct contact areas, cause the first film to take on the second appearance of the second film. The visually-distinct contact areas being of a uniform gauge and configured to separate before either of the first film or the second film fails when subjected to peel forces.

The invention comprises, in an embodiment, a resealable packaging structure comprising a container having a bottom and at least one sidewall extending upwardly therefrom, wherein the sidewall terminates in a flange. A flexible resealable lid is sealed to the flange. The lid comprises a polyethylene terephthalate layer disposed adjacent the flange, a pressure sensitive adhesive layer disposed adjacent the polyethylene terephthalate layer, and an oriented polypropylene layer disposed adjacent the pressure sensitive adhesive layer. The polyethylene terephthalate layer comprises a laser scored line which penetrates through the thickness of the inner layer but not through the outer layer and defines an opening portion that can be lifted out of the plane of the inner layer, thereby creating an opening through the lid defined by the laser score line.

A liner for use with a fluid dispensing vessel. The liner includes a flexible pouch defining an interior region and configured to be placed in a fluid dispensing vessel. The pouch includes a top end that is partially sealed and that includes a first opening. The pouch includes a fluid passageway defined by at least two sealed boundaries and that leads from the opening to the interior region. The pouch includes a bottom end that includes a second opening. The liner includes a fluid dispensing fitment connected to the pouch and configured to be in fluid communication with interior region via the second opening. When fluid is poured into the interior region of the pouch through the opening, it can be dispensed from the pouch through the fitment.

A method of forming reinforced packages. The method can comprise forming an attached web by adhering a blank to a web of material and moving the attached web in a downstream direction through at least a tube forming assembly and a carton forming assembly. The method also can comprise at least partially forming a tube by folding at least a portion of the web of material as the attached web moves through the tube forming assembly, forming a reinforcement sleeve by folding at least a portion of the blank so that the reinforcement sleeve extends at least partially around the tube as the attached web moves through the carton forming assembly, and forming a reinforced package comprising the reinforcement sleeve and a tube portion by separating the tube portion from a remainder of the tube, the reinforcement sleeve being adhered to the tube portion.

A machine for the production of a stand up pouch from a web includes a film feed which moves the web at continuously at a constant speed through a punching station, a folding station, and a welding station. The welding station includes a pair of seal bars which are driven by a server motor at a speed equal to a speed of the web during the welding. The punch station includes at least one electromagnetic punch.

A pinch bottom sack fillable with bulk good includes a sleeve with at least one area element, wherein the sleeve includes a mesh and the area element a handle means including a load element at which a load force is applicable for lifting the sack, and the load element is configured such that it extends at least in some areas at least in a load condition in which the load force acts at the load element opposite to an outer side of the area element.

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.

A method and apparatus for making bags or pouches is disclosed. An ultrasonic sealer may be used to form the seals. Sealing patterns may be used to provide a desired strength profile.

The present invention discloses a method for preparing a paper band that incorporates a composite paper mesh, intended for the manufacture of bags for horticultural products, wherein the embodiment of the composite mesh comprises a process that includes dividing a paper reel (1) into continuous longitudinal strips (2-5), transversely segmenting a paper reel (6) to prepare cross pieces (7) which are applied on two longitudinal strips (2-5) parallel and spaced apart from each other, in successively distant positions along said strips and bonded by gluing, and applying on the support base grid structure thus obtained a mesh (10) of paper yarn which is joined to the support base by gluing, and that can be divided into portions that can be used for covering windows or openings included in the paper band, all this with the aid of automated means.

A method of making a paper bag for containing sanitary products, which includes conveying a paper web having a first side and a second side in a conveying direction; Applying a sealable coating to the first side of the paper web in sections, and applying second coating strips extending substantially transversely to the conveying direction and spaced apart from one another in the conveying direction; folding onto itself the first side of the paper web along the direction of conveyance to form a two-ply web having a folding configuration; and heat sealing the second coating strips to form side seams each defining a bag interior; separating the two-ply web along the heat sealed side seams to separate the two-ply web into individual paper bags.
