Insulated bag

A method for assembling an insulated bag comprising:

• folding a first main panel of a pair of opposing main panels relative to a first side panel of a pair of opposing side panels about a main crease line, the main panels, the side panels, and the main crease line defined in an insulated blank, the insulated blank comprising an insulation batt, a first sheet, and a second sheet, the insulation batt encapsulated in a blank cavity defined between the first sheet and the second sheet, a blank border extending around a perimeter of the insulated blank, the blank border defined by a perimeter portion of the first sheet being in facing engagement with a perimeter portion of the second sheet, the blank border encompassing the blank cavity and defining an insulated portion of the insulated blank, the insulated blank defining a first end and a second end, the first end disposed opposite from the second end;
• attaching the first end to the second end;
• forming a bottom panel of the insulated bag by folding a portion of the bottom panel relative to the main panel about a bottom crease line, the bottom panel and the bottom crease line further defined by the insulated blank;
• folding a wing about a base wing crease line towards the first side panel, the base wing crease line defined at an intersection of the wing and the first side panel;
• and
• attaching the wing to the first side panel.
