B flute is amongst the most commonly used types of cardboard used for packaging applications. Being 3mm in thickness, it is exceptionally versatile and it gives good all-round performance in all types of packaging. It typically has a total of 47 flutes per linear foot including a thickness of 1/8^th. 100% recycled cardboard is packaging made entirely from recycled fibers, which is considered a sustainable option. It's made from recycled materials, such as post-consumer waste or by-products from manufacturing processes, instead of virgin materials like wood pulp.
