Abstract
A blank includes an inner sheet having at least a base layer having a first side and a second side opposite the first side, the inner sheet including a film coupled to the first side of the base layer, and an outer sheet coupled to the second side of the base layer by an adhesive deposited between the outer sheet and the base layer such that a plurality of voids are formed between the outer sheet and the inner sheet, wherein the blank is configured to be folded into a multi-ply bag such that the film defines the inner cavity of the multi-ply bag.
Claims14
A repulpable multiple-ply container adapted for thermal management of a payload, the container comprising:
- a film layer defining an interior of the container configured to accept the payload therewithin, the film layer further configured to offer low emissivity and high reflectivity to radiant heat;
- a first paper layer coextensive with and continuously coupled to the film layer, the film layer and the first paper layer together providing an efficient combined R-value for thermal management within the interior of the container, the first paper layer having a first end, a second end, a top end, and a bottom end;
- a first adhesive pattern providing intermittent bonding points spaced between the first end and the second end and from the top end to the bottom end,
- a second adhesive pattern comprising a first strip of adhesive extending along the first end from the top end to the bottom end, a second strip of adhesive extending along the bottom end from the first end to the second end, and a third strip of adhesive extending along the second end from the top end to the bottom end;
- and
- a second paper layer coextensive with the first paper layer, intermittently bonded to the first paper layer opposite the film layer via the adhesive layer bonding points,
- wherein a plurality of air-filled gaps are created by the first paper layer, the second paper layer, and the adhesive layer bonding points further insulating the interior of the container while maintaining the repulpability of the container.

A container adapted for thermal management of a payload, the container comprising:
- a blank assembly comprising
- a first sheet assembly, the first sheet assembly comprising a base layer and a metallized film applied to the base layer, the metallized film comprising a reflective layer and a protective layer;
- a second sheet adhered to the base layer, the second sheet adhered to the base layer by an adhesive arranged at intermittent bonding points such that a plurality of voids are defined by the inner sheet assembly, the outer sheet assembly, and the adhesive, the intermittent bonding points organized into columns and rows between a first end and a second end and from a top end to a bottom end of the blank;
- wherein the plurality of voids define a plurality of air pockets, wherein at least one of the plurality of air pockets comprises a vent at the top end;
- wherein the blank assembly is defined from a plurality of wall panels, each wall panel being one of a main panel and a side panel;
- wherein the blank assembly is formed into the container by arranging the wall panels in end-to-end relationship to define a side wall of the container and by arranging a portion of the blank assembly as the bottom of the container such that the second sheet defines an outer surface of the container,
- wherein the metallized film is arranged to define an interior surface of the container, the interior surface defining a cavity configured to accept the payload therewithin, the metallized film further configured to offer low emissivity and high reflectivity to radiant heat;
- wherein the metallized film comprises a polymer;
- wherein each of the base layer and the second sheet are of paper;
- wherein each of the base layer, the second sheet, and the metallized film are repulpable.
