What kind of paper is a packaging paper bag?

Packaging paper bags are usually made of high-strength, printable paper such as kraft paper, white cardboard, copperplate paper, or laminated paper. The specific material selection depends on the requirements of the application for load-bearing, waterproof, appearance, and environmental protection.

Common paper types and characteristics

Kraft paper: divided into white and yellow, the paper is tough and tear resistant, suitable for making shopping bags, clothing bags, and industrial packaging bags. Among them, white kraft paper has become the mainstream material for environmentally friendly handbags because it can be used without the need for lamination.

White cardboard: thick and firm, with a smooth surface and full printing colors, commonly used in high-end gift bags, brand handbags, such as luxury goods or bookstore bags.

Copperplate paper: High glossiness, strong three-dimensional image representation, suitable for promotional paper bags with full page color printing, but slightly lower stiffness than white cardboard.

Coated paper: A layer of polyethylene (PE) film is coated on the surface of food grade paper, which has waterproof and oil resistant properties and is widely used in takeaway food boxes, burger bags, milk tea takeaway bags, etc.

Gray Bottom Whiteboard Paper: The front is white and smooth, and the back is gray. It has a low cost and is suitable for mid-range packaging needs, such as ordinary gift bags or shoe and clothing accessory bags.
