Described embodiments provide systems and methods for controlling the temperature of an item with a sheet. The sheet includes a front side and an obverse side, a first adhesive disposed along a first edge of the sheet on the front side of the sheet, such that when the sheet is folded over the item, the first adhesive engages with the front side of the sheet to create a container pocket having a container volume; and a second adhesive disposed on the front side of the sheet such that when the sheet is folded over the item, the second adhesive engages with the sheet to create a temperature control pocket with a volume less than the container volume. The sheet also includes a third adhesive for engaging with an ice pack, and a fourth adhesive and a fifth adhesive for creating side enclosures for the temperature control pocket.

Disclosed is a bulk bag having self-standing loops. The bulk bag is configured with a bag-shaped body having a reversed “U”-shaped loop protruding upwardly from an outside thereof and configured to flexibly stand upright by itself from a folded position upon unstacking of bodies, wherein the loop is coupled to the body at a position spaced downwardly apart from a top edge of the body by a predetermined distance, the loop having an air tube having a predetermined length and coupled to an outside of the loop. The loop is configured with a semicircular arc-shaped hook portion and “I”-shaped supporting portions respectively extending from opposite ends of the hook portion, and the air tube is coupled with the hook portion and an at least one supporting portion and is heat-treated and flexibly bent at a portion corresponding to a boundary point between the hook portion and the supporting portion.

A plastic film bottom bag has a plastic film front wall that is welded or adhesively joined to side wall sections of adjoining plastic film side walls, and/or a plastic film rear wall that is welded or adhesively joined to the side wall sections of the adjoining plastic film side walls, so as to form a seam or casing seam. Further disclosed is a plastic film bottom bag, in which at least one, in particular both, plastic film side walls are provided with a side fold that comprises a welded or adhesive joint extending from or at a distance from the bag opening edge in the direction of the bag end or up to the bag end. The disclosure further relates to blanks for the plastic film bottom bags described herein and to the use of the plastic film bottom bags described herein, as reusable bags or reusable handbags.

A thermal bag includes a thermal bag main body and an upper cover. A side shaping board is interlaid between the fabrics around the thermal bag main body. The upper cover includes a pair of half covers. An opening assembly is connected between the two half covers. Atop shaping board is interlaid between the fabrics of each of the half covers. A hinge assembly is connected between the side shaping board and the top shaping board located at the same side of the opening assembly. The hinge assembly drives the half covers to open/close the opening of the thermal bag quickly.

A tamper evident package for secure delivery of a product is disclosed. The tamper evident packaging includes a plurality of sidewalls having a closure providing access to an interior compartment of the packaging. The closure includes a closure slide that urges a closure seal into cooperative engagement during movement of the closure slide. Cooperating ratchet teeth are provided in the closure slide and at a closed end of the closure to retain the closure slide in a locked position. The closure slide includes a land for carrying a unique identifier code. The unique identifier code is visible through a window in the closure when the closure slide is in the locked position. The tamper evident packaging may be used with a product delivery service where the unique identifier code is used to identify an order through a packing of the product through receipt of the product by the customer.

A food carrying bag is provided having the dimensions to accommodate carrying a submarine sandwich or any other elongated food item in a horizontal orientation within the food carrying bag. The food carrying bag has a front panel, a back panel, and two opposite closed side ends with an opening along the top of the bag. In one embodiment, the food carrying bag includes a bottom gusset on the bottom panel. Alternatively, the food carrying bag includes a bottom gusset on the bottom panel and side gussets on the side panels. The food carrying bag includes handles that can be attached to the top of the bag or that can be cut out of an upper portion or region of the food carrying bag. The height of the food carrying bag is shorter in height and the width is accommodates most submarine sandwiches and elongated food items.

A tamper evident delivery bag assembly includes a first and second that each includes an upper section terminating at an upper edge of the first panel and an opposed upper edge of the second panel. The upper edges cooperate to define a bag opening into a content receiving region. The upper sections are movable between an opened condition and a closed condition, the closed condition where the upper edges are oriented in opposed, adjacent, relationship to one another. A handle is mounted to each upper section of the first and second panels, and each handle includes a pair of spaced-apart leg portions that are aligned adjacent one another when the upper sections are oriented in the closed condition. A single use closure tape is laterally mounted to the first panel upper section, and includes an upper lateral portion extending laterally above the first edge thereof in an unsealed condition. The tape upper lateral portion includes a pair of cutouts strategically aligned with the first leg portion of the first handle. The tape upper lateral portion can be folded over the second edge of the second panel such that an adhesive of the tape is brought into contact with the exterior surface of the second panel, substantially sealing the bag opening in a sealed condition. The leg portions of the handles are received through the cutouts of the tape.

A reusable, re-foldable bag with gussets includes a first bag wall; a first side panel; a second side panel; a second bag wall aligned and joined to the first bag wall by the first side panel and the second side panel at a first heat sealed side edge, a second heat sealed side edge, respectively; a bag bottom comprising a substantially planar, foldable surface, the first and the second bag walls, the first and the second side panels, and the bottom formed of a single sheet and together arranged to form a bag defining an opening at a top thereof; a first gusset and a second gusset heat sealed onto the first side panel at the interior of the bag; and a third gusset and a fourth gusset heat sealed onto the second side panel at the interior.

A tamper evident delivery bag assembly includes a single use closure tape is laterally mounted to the first panel upper section, and includes an upper lateral portion extending laterally above the first edge of the bag assembly in an unsealed condition. The tape upper lateral portion can be folded over the second edge of the second panel such that an adhesive of the tape is brought into contact with the exterior surface of the second panel, substantially sealing the bag opening in a sealed condition. The leg portions of the handles are received through the cutouts of the tape. The closure tape member further includes a note tab extending downwardly from a middle lateral portion thereof. The note tab includes a tab adhesive and a removable protective cover. When the protective cover is removed, the note can be placed between the tab adhesive and the exterior surface of the first panel, and adhered therebetween in a mounted condition.

A self-weighing expandable bag includes an inner receptacle that can slide vertically within an outer sleeve under the weight of bag contents. One or more springs, which may include coils and/or elastic fabric, connect the inner receptacle to the outer sleeve. One or more bag handles are attached to the sleeve. As the weight of the contents of the receptacle increases, the receptacle slides down within the sleeve and increasingly protrudes under the sleeve, expanding the vertical extent of the bag and revealing graphical markings underneath the sleeve and/or within a window defined in the sleeve.
