Insulating bag

An insulating bag assembly comprising:

• an insulating bag defining a top bag end, a bottom bag end, and an interior cavity, the insulating bag comprising:
• a pair of opposing main panels and a pair of opposing side panels, each of the main panels and side panels extending from the top bag end to the bottom bag end;
• a bottom panel disposed at the bottom bag end;
• and
• an upper bag portion extending from the top bag end;
• wherein the insulating bag comprises a paper base layer, a temperature-preserving liner applied to the paper base layer, a protective layer positioned over the temperature-preserving liner, and the temperature-preserving liner further comprises a reflective layer;
• and
• bag contents received within the interior cavity, the bag contents comprising a cold pack;
• wherein the protective layer is configured to protect the reflective layer from oxidation.

A method of packaging a food item in an insulating bag comprising:

• providing the insulating bag, the insulating bag defining a top bag end, a bottom bag end, an interior cavity, and a cavity opening formed at the top bag end, the insulating bag comprising:
• a pair of opposing main panels and a pair of opposing side panels, each of the main panels and side panels extending from the top bag end to the bottom bag end;
• a bottom panel disposed at the bottom bag end;
• a pair of opposing main top flaps, each main top flap hingedly connected to a corresponding one of the main panels at the top bag end;
• and
• a pair of opposing side top flaps, each side top flap hingedly connected to a corresponding one of the side panels at the top bag end;
• wherein the insulating bag comprises a paper base layer, a temperature-preserving liner applied to the paper base layer, a protective layer positioned over the temperature-preserving liner, and the temperature-preserving liner further comprises a reflective layer, the protective layer being configured to protect the reflective layer from oxidation;
• arranging the insulating bag in an open orientation, wherein each of the side top flaps and the main tops flaps are folded away from the interior cavity to uncover the cavity opening;
• inserting the food item into the interior cavity through the cavity opening;
• and
• arranging the insulating bag in a closed orientation, wherein each of the side top flaps and the main top flaps are folded towards the interior cavity to cover the cavity opening.

An insulating bag comprising:

• a pair of opposing side panels;
• a pair of opposing main panels, each side panel attached to each main panel, the pair of opposing main panels and the pair of opposing side panels together defining a top bag end and a bottom bag end opposite the top bag end;
• a pair of opposing main top flaps, each main top flap hingedly connected to a corresponding one of the main panels at the top bag end;
• a pair of opposing side top flaps, each side top flap hingedly connected to a corresponding one of the side panels at the top bag end;
• and
• a bottom panel disposed at the bottom bag end;
• wherein:
• the insulating bag comprises a paper base layer, a temperature-preserving liner applied to the paper base layer, a protective layer positioned over the temperature-preserving liner, and wherein the temperature-preserving liner further comprises a reflective layer and the protective layer is configured to protect the reflective layer from oxidation;
• and
• the insulating bag defines an interior cavity configured to receive bag contents therein.
