White kraft paper bags are packaging containers made of composite materials or pure kraft paper. They are odorless, non-polluting, and meet national environmental standards. With high strength and high environmental protection, they are one of the popular eco-friendly packaging materials.

Yellow kraft paper bags, also known as natural-colored kraft paper bags, exhibit a yellowish-brown hue overall. This color gives the kraft paper bag a more natural and environmentally friendly feel. Due to their inherent yellow color, yellow kraft paper bags sometimes struggle to highlight printed colors and are more suitable for printing simple patterns.
