D-Flute is a new type of corrugated fluting introduced by Pratt Industries that is smaller and has flutes that are closer together than traditional B-flute. It can be substituted for B-flute and other grades in shelf-ready packaging, self-supporting packaging, and wrap around applications. D-Flute provides benefits like 25-30% more boxes per unit than B-flute, reducing the number of trailers and units needed to transport. It also offers environmental savings, supply chain savings, improved shelf-ready functionality with more precise die-cutting and cleaner tearing, and a better printing surface with reduced washboarding.
