This is a general term for any type of paper that is not kraft or recycled paper. Specialty papers can be made from a variety of materials, such as cotton, bamboo, or hemp. They are often used for high-end shopping bags that are intended to be kept and reused.
The type of paper used for a shopping bag will depend on a number of factors, including the intended use of the bag, the desired strength and durability, the aesthetic appeal, and the cost.
