B-flute (3.5mm) is thicker, stronger, and better for heavier products (>500g). It offers superior crush resistance for shipping. E-flute (1.5mm) is thinner and lighter — ideal for lightweight cosmetics, books, and flat items where print quality is a priority. E-flute holds sharper print detail than B-flute.
