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.

The bag may include a draw tape that may be used to cinch closed the opening of the bag. The draw tape has at least one stretched elastomeric strip attached to the draw tape in an extended condition. The draw tape may be smaller in size than the bag sidewalls. The draw tape may include an elastic characteristic, such as patterned ribs. In one embodiment, the roll of bag is kept under tension to maintain the elastomeric strips in a stretched condition.

A form-fill-seal machine and a method for manufacturing and filling a bag (100) having a drawstring tape or cord. The form-fill-seal machine includes a device to guide a film on the machine. A conveying device positions at least one drawstring tape or cord on the film. A folding device folds the film to form a first sheet and a second sheet of the bag. First and second welding jaws weld the first sheet and the second sheet to close two sides of the bag and leave a third side of the bag open. A filling chute fills the bag by the third side of the bag. Third welding jaws close the bag by sealing the third side.

Multi-layer bags may be formed to include first and second sidewalls joined along a first side edge, an opposite second side edge, and a closed bottom edge. The first and second layers may be non-continuously laminated together to include bonded regions in which the layers are bonded and unbonded regions in which the layers are not bonded. Such a bag may be described as a bag-in-a-bag type configuration in which the inner bag is non-continuously bonded to the outer bag. The inventors have surprisingly found that such configurations of non-continuous bonding provides increased and unexpected strength properties to the multi-layer films and bags.

The plastic bag may include flexible thermoplastic sidewalls that have a pattern imparted onto them. The wrinkle pattern may be a plurality of linear ribs formed into the sidewall that may be arranged adjacent and parallel to one another. To impart the pattern to the sidewall, a thermoplastic web used to make the sidewall may be directed between a first cylindrical roller and a second cylindrical roller, each of which may have a plurality of spaced ridges extending about their peripheries. When the web is directed between the first and second rollers, the meshing of the ridges may form ribs into the web.

The present invention is directed to a drawstring bag comprising a first panel and a second panel. The first panel and the second panel are joined along a first side, a bottom, and a second side. The first panel and the second panel thereby define an upper opening of the bag. The drawstring bag may further comprise a first pair of drawstrings disposed within a first hem along the upper opening of the bag in the first panel and a second pair of drawstrings disposed within a second hem along the upper opening of the bag in the second panel. The first pair of drawstrings may comprise a shorter elastic drawstring and a longer inelastic drawstring.

The invention relates to a form fill seal machine (200) for producing and filling a bag (100) with a band, said bag comprising a first sheet (112) and a second sheet (114) that together form a first edge (117) and a second edge (118) of the bag, and a band closing device (120), the machine comprising:a device (210) configured to feed a film (1) onto the machine,a conveying device (215) configured to position at least one band (136) on the film,a folding device (240) configured to fold the film (1) in such a way as to form the first sheet (112) and the second sheet (114) of the bag,welding jaws (245a, 245b) configured to weld the first sheet (112) and the second sheet (114) in such a way as to close two sides of the bag and leave a third side of the bag open,a filling chute (250) configured to fill the bag via the third side of the bag, andwelding jaws (255) configured to close the bag by sealing the third side.
