Square-bottom paper bags feature a square/rectangular base with gusseted sides, allowing them to fold flat for storage and unfold into a stable cube/rectangular prism shape. They stand securely, offer large capacity, and provide strong load-bearing capabilities. Ideal for food packaging, takeout containers, and similar applications.

Paper handles are carrying components made from materials such as kraft paper, cardstock, and specialty paper.
