A reinforcement for a bag or a sack is described. The reinforcement has an elongate body with a thinner mid-section than its ends. The reinforcement also has a locking clip slidingly engaged with the second middle portion. It is configured to slide in a direction parallel to the longitudinal axis from a first position, where the locking clip is not aligned with the bag fold line and where the bag and the elongate body are permitted to fold along the bag fold line, to a second position, where the locking clip is substantially aligned with the bag fold line and the body fold line, where the locking clip substantially prevents the bag and the elongate body from folding and substantially maintains the bag in an open position.

A system for structurally supporting the interior of a fluid reservoir is disclosed. The reservoir can have a reinforcing brace within the reservoir. The brace can be splittable or separable, which can allow the reservoir to be inverted, for example for easier cleaning. The brace can maintain the shape of the reservoir when the reservoir is filled with liquid, preventing the reservoir from forming a cylindrical cross-section. The control of the shape of the reservoir can prevent or minimize distortion of a backpack which is carrying the reservoir.

The present disclosure relates to a composite storage bin comprising a frame and a sack body: the frame comprises four U-shaped elbows with identical designs in length and bending for cubic contouring and multidirectional placement of the assembled frame; the sack body mounted on the assembled frame coordinates an orientation of placing the frame to deflect an opening of the sack body upward or sideways. The sack body, which is internally hung in or externally encloses the frame, has an opening around which positioning units stopped at elbows are prepared for supporting and positioning the sack body.

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.

A handled shipping bag or sack is described that is capable of manufacture without requiring registration of the handle to a width of the bag. The shipping bag includes a cover tape having perforations particularly well suited for finger holds of a user that center the users hand relative to the width of the bag without requiring a registration of the finger holds relative to the bag during the manufacture of the bag.

The invention discloses bi-axially oriented coated polyester films having high tear initiation resistance and comprising a polyester base film and a heat sealable coating, said heat sealable coating comprising one or more amorphous copolyester(s) comprising units of terephthalic acid, naphthalene dicarboxylic acid and at least one diol. The films are heat-sealable and peelable to polyester and aluminium containers. The invention also relates to a process for the manufacturing of such films, to the use of said films in food packaging and to the packages obtained therefrom.
