A tamperproof bag includes a base, a pair of opposing end walls, and a pair of opposing sidewalls extending upwardly from the base to form an open upper end, defining an interior volume. Each end wall includes a height greater than a height of each sidewall, allowing for easier handling. An adhesive strip is disposed on an interior-facing surface of at least one end wall. The adhesive strip is configured to secure the end walls together to form a sealed closure and prevent access to the interior volume. Separation of the pair of end walls once adhered forms a tear in the bag, which may identify that an unauthorized access attempt to the bag has been made and prevents reclosure of the bag. A tab connected to a perforated strip that aligns with the adhesive strip provides a mechanism for accessing the interior of the bag.

A bag wherein in a first mode the mouth of the bag has a perimeter defined by the front panel and back panel and two sides of the bag closure. Strips at the mouth are not configured to close the bag in the first mode. The bag also has a second mode. This allows a second mode opening to the bag's containment region to be created. The perimeter of the second mode opening is defined by the two mutually engageable closure strips.

A method includes obtaining an elongated supply strip formed from an elongated profile body and an elongated flange and modifying portions of the profile body and/or the flange in different locations along a length of the supply strip to define termination ends of closure strips. The supply strip is separated into at least one of the closure strips at the termination ends. The flange in the closure strip is coupled to one or more panels of a resealable enclosure, and the panels are partially sealed to define an opening into the resealable enclosure. The profile body is configured to repeatedly couple with and decouple from itself to close and open the opening in the resealable enclosure. The panels are sealed to each other such that the ends of the closure strip are sealed between the panels.

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.

Provided is a receptacle system, including a receptacle chassis that defines a volume and that defines, at an edge of the receptacle chassis, an aperture that provides access to the volume. The receptacle chassis includes a first face that is adjacent the volume, and a second face that is opposite the receptacle chassis from the first face and that is adjacent to an exterior volume. The receptacle chassis includes an object securing system that is included on at least one of the first face or the second face, and that is configured to secure the receptacle chassis to an object. Also, provided is a receptacle template system, including a planar member defines a first slot and a second slot that extend through the planar member from a first face to a second face and that are configured to receive a cutting device.

A tear away food bag includes tear seams, or other features, providing controlled tearing away of portions of the bags. The food bag is suitable for use as a lunch bag, a picnic bag, or a take out food bag. A bottom portion of the bag may be torn away from the food bag to provide a food holder and top portions maybe torn away from the food bag to provide place mats.

The product efficiency of bags each with an end face part is increased. A panel webs is guided to be divided along a line of weakness of the panel web and to be folded along division edges of the panel web. This guiding of the first panel and temporary sealed sections cause a side gusset to be cut open along a line of weakness of the side gusset such that open surfaces are formed. After the forming of the open surfaces, an end face web is supplied to be superposed on folded parts of the panel web and the open surfaces of the side gusset.

A rock bag and method of manufacturing same are provided herein. In one embodiment, the rock bag has a first set of opposed sides, each side of which is substantially the same dimensions, a second set of opposed sides, each side of which is substantially the same dimensions, and a bottom side formed to operatively couple with the first and second set of opposed sides such that the rock bag forms an enclosure with five sides and an opening opposite the bottom side. And the material forming the sides comprises between 40% and 90% rock content.

The invention relates to a folded bag and a method for forming a bag from a square or rectangular shaped sheet, which method comprises the steps of dividing the sheet into nine fields arranged such that eight fields surround a central field; folding the sheet along folding-lines between and across the fields in such a way that the central field forms the bottom of the bag and the eight surrounding fields form the sides of the bag and at least one inner wall providing separated compartments in the bag.

Disclosed are embodiments of a versatile storage bag and methods of making same. The versatile storage bag may have first and second sidewalls, a double-locking closure mechanism with a first closure element extending along the first sidewall and a second closure element extending along the second sidewall, each closure element having a channel and an elongated member configured for interlocking with one another. A double-seal along three sides of the first sidewall and the second sidewall form a gusset between two seals, leaving an opening through the double-locking closure mechanism. Corner seals may be formed at the corners of the first and second sidewalls, further reinforcing the double-locking closure mechanism for an airtight and hence waterproof seal. The versatile storage bag may be made of a food-grade polyethylene vinyl acetate blend, approximately 90% or less ethylene vinyl acetate and approximately 10% or less polyethylene.
