A woven laminated plastic bag having features that 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 sealed closure that at least a portion of which can be easily peeled open with less force than the remainder of the sealed closure.

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.

Equipment transport bag assemblies (20, 92, 98, 145, 152, 182) each including an upright, open-top, equipment-receiving bag (22, 110, 158) with associated equipment-handling assemblies (24, 92, 102, 164, 184). The assemblies (24, 92, 102, 164, 184) have load-bearing strap units (34, 114, 166, 186) operably associated with the transport bags (22, 110, 158) so that the strap units (34, 114, 166, 186) bear the primary loads during lifting and handling of the bag assemblies (20, 92, 98, 145, 152, 182).

Disclosed fluid reservoirs include closure mechanisms for sealing an upper opening of the reservoir. The reservoir can have plates adjacent the upper opening. When the upper end of the reservoir is folded, the plates can be positioned on opposite sides, and a closure frame can be slid over the plates to pressure them together. The plates can have pins that engage with slots in the closure frame, and a separate closure lock can be slid over the end of the closure frame to prevent the pins from exiting the slots. The plates can also bias the opening open when the closure is not engaged. Also disclosed are flexible fluid reservoirs that include structural elements, such as baffles, that help retain a desired shape of the reservoir when filled or empty. Some baffles can be elastically deformable to allow flattening and expansion of the bladder while biasing toward a neutral position.

A system, method and apparatus for transferring bulk material for transport, the method includes placing a first quantity of bulk material in a soft-sided bulk material container, extending a first hold-in across the container from a first side of the container to a second location, the second location being substantially toward a second side of the container, wherein the first hold-in is secured to the first side of the container, securing the first hold-in to the second location and placing a second quantity of bulk material in the container, the second quantity covering the first hold-in and securing the first hold-in to the second location with a weight of the second quantity of bulk material.

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.
