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 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.

Flexible film packages having a partial, initial seal against ambient atmosphere and are easily openable and reclosable. The flexible film packages are generally resealable to extend the shelf-life or freshness of products contained therein once the package is initially opened. By one approach, the flexible film has two opposing edge portions that meet to form a longitudinal seal extending from a first end seal to a second end seal. The flexible film may have a score that defines a package opening. An elongated closure layer (14) may extend over the score and may extend from a first end seal (26) to a second end seal (28) and within the opposing edge portions that form the longitudinal seal (24). The elongated closure layer may have a tack-free gripping portion (40) used to release at least a portion of the elongated closure from the flexible film to form the package opening.

A packaging material 1 is configured to pack a viscous product having one surface, an opposite surface, and side surfaces. The packaging material 1 includes a sheet 2 having a first surface portion 7 configured to cover the one surface of the viscous product, side surface portions 8-1 to 8-4 configured to cover the side surfaces, and second surface portions 9-1 to 9-4 disposed at the opposite surface, and tear tape 3 adhered to the sheet to cut the sheet. The tear tape is provided to start from the side surface portion or the second surface portion and to be branched into a first branched tape 3a and a second branched tape 3b across the first surface portion. The first branched tape is provided to pass through an edge of one side part of the first surface portion, and the second branched tape is provided to pass through an inner part of its width to form a grip 23 at the other side of the first surface portion, and continuously, to arrive at the other end of the first surface portion through an edge of the other side part of the first surface portion.

A cutting tape includes a leading portion, a first base, a second base and a seal layer. The leading portion is welded on a sealant layer with the seal layer interposed therebetween. The first base and the second base, which are laminated on the leading portion, respectively include thin laminated portions and body portions to be welded on the sealant layer. The laminated portions are welded on the leading portion. The body portions respectively have a substantially trapezoidal cross section projecting toward the sealant layer and having an inclined surface adjacent to the leading portion.

The present invention provides a package (10) comprising an outer film layer (32) and at least one inner film layer (34,36), the inner and outer film layers being mutually laminated. The package also comprises a pair of mutually spaced lines of weakness (20) in at least the outer film layer, and means (22) for initiating tearing of the film layers. The lines of weakness and tear initiation means are disposed such that activation of the tear initiation means causes controlled tearing of all the film layers along the lines of weakness. The package is particularly suitable for block products such as chocolate bars.

A resealable packaging container for housing goods includes a wrapper of a flexible material that encloses the goods within. A perforated panel is cut into the wrapper for movement between open and closed positions. The perforated panel defines a wrapper opening in the wrapper when the perforated panel is in the open position to allow access to the goods disposed within the resealable packaging container. A pressure sensitive coated collar adhesively engages the inner surface of the wrapper underneath the perforated panel to partially surround the wrapper opening. The pressure sensitive coated collar includes an open central portion that is disposed inwardly of the wrapper opening and an exposed region that extends between the wrapper opening and the open central portion. The perforated panel reseals to the exposed region of the pressure sensitive coated collar in the closed position.

A tearable closure and a container with a tearable closure is disclosed. The tearable closure includes non-penetrating perforations or score lines in and across the tearable closure on a first side, and has continuous film material on the second side. Such tearable closure can be incorporated into one of numerous types of containers, including envelopes, boxes, and bags. The tearable closure can be a flap, a lid, or a tape.

A reclosable flexible package having a reclosable closure comprising easy-to-use adhesive securement means in combination with non-reclosable closures provided above and below the reclosable closure. The package provides a re-openable seal for reclosing the bag upon a partial discharge of the contents thereof, such as food contents. The flexible package offers manufacturing ease and cost-savings, and tamper-resistance. The flexible package also may be incorporated into a bag-in-box package configuration. Methods of making and filling the package also are provided.

A ream wrap package formed by wrapping a sheet of polymeric film (21) around a stack of paper, the sheet having been severed from a web polymeric film having at least one line of weakness formed therein in the machine direction (MD) and within a region of the transverse direction (TD), to form a rectangular tube with sides overlapping, sealing one side to the other to form a girth seal (24), closing the tube at each end to form an envelope seal with tucked in ends and overlapping flaps (25, 25′, 26, 26′), at least one of which is trapezoidal, so that in the formed package there is at least one line of weakness (27) extending along the whole length of a surface of the package outside the girth seal, positioned so that it terminates at each end of the package within a region of the TD defined by that portion of the overlapping flaps where there are only two layers of the overlapping film
