E-Flute

E-Flute is a corrugated micro flute material. It’s thin profile (1/16”), cushioning properties, and excellent printability serves as an excellent alternative to conventional folding cartons where strength and durability may be a concern. If you want the functionality of a folding carton and strength of a corrugated box, an E-flute carton can provide the solution.
