A liner comprising a body portion and a flap portion. The body portion comprises a front, a back, a first side, a second side, and a bottom. The body portion defines a cavity. The flap portion is hingedly connected to a top end of the back of the body portion. The flap portion is sized to cover the cavity. The body portion and the flap portion comprise a single piece of insulative material.

A modular box assembly includes a box; a first thermal liner constructed of a first length of pre-laminated material, the pre-laminated material comprising an insulation batt in facing contact with a first sheet and with a second sheet, the first thermal liner defining three first liner panels; and a second thermal liner constructed of a second length of the pre-laminated material, the second thermal liner defining three second liner panels. A bottom box panel is covered by one of a first liner panel not covering any side box panel and a second liner panel not covering any side box panel. The insulation batt is formed from a mixture of reinforcement fibers and thermoplastic binder fibers, the reinforcement fibers comprising one of natural fibers, recycled cardboard, and a mixture of recycled cardboard and paper fibers.

A modular box assembly includes a box with side panels defining a box cavity, a first thermal liner positioned within the box cavity, the first thermal liner including a first insulation batt disposed between sheets, the first thermal liner defining three first liner panels, at least one box side panel being covered by a first liner panel, and a second thermal liner positioned within the box cavity, the second thermal liner including a second insulation batt disposed between sheets, the second thermal liner defining three second liner panels. At least one other of the side box panels is covered by a second liner panel. The bottom box panel is covered by either a first liner panel not covering any side box panel or a second liner panel not covering any side box panel. Each insulation batt can be formed from a mixture of thermoplastic binder fibers and reinforcement fibers.

A box assembly includes a box defining a box cavity within the box; and at least one insulated panel disposed within the box cavity, the at least one insulated panel including at least one board and at least one insulation batt, the at least one board laminated to the at least one insulation batt, the at least one insulated panel configured to at least partially insulate the box cavity.

A thermal insulation article includes a thermally insulating pad shaped to be positioned in a cavity of a rectangular prism shipping container. The pad includes a solid compostable panel formed primarily of starch and/or plant fiber pulp that holds together as a single unit, and a water-proof or water-resistant film forming a pocket enclosing the panel. The panel includes a first section, a second section, and a third section connecting the first section to the second section, the first and second section each having a central portion and two flaps that extend from the central portion beyond the third section, and wherein the panel is foldable into an open box.

A modular box assembly includes a box defining a box cavity within the box, the box further defining a top end and a bottom end, the top end defining a box opening connected to the box cavity, the box including a side panel extending from the top end to the bottom end; a shoulder attached to the side panel, the shoulder extending inward from the side panel and into the box cavity, the shoulder including a first sub-shoulder and a second sub-shoulder, the first sub-shoulder, the second sub-shoulder, and the side panel defining a shoulder channel; and an inner box disposed in the box cavity, the inner box including a channel tab, the channel tab frictionally engaging the shoulder channel to secure and suspend the inner box within the box cavity between the top end and the bottom end.

A liner for use with a fluid dispensing vessel. The liner includes a flexible pouch defining an interior region and configured to be placed in a fluid dispensing vessel. The pouch includes a top end that is partially sealed and that includes a first opening. The pouch includes a fluid passageway defined by at least two sealed boundaries and that leads from the opening to the interior region. The pouch includes a bottom end that includes a second opening. The liner includes a fluid dispensing fitment connected to the pouch and configured to be in fluid communication with interior region via the second opening. When fluid is poured into the interior region of the pouch through the opening, it can be dispensed from the pouch through the fitment.
