The “best” flute depends on your specific needs:

  • E-Flute (1.6mm): Best for retail packaging and high-quality printing (like mailer boxes) but offers less cushioning.

  • B-Flute (3.2mm): A great all-rounder. Good crush resistance and a decent printing surface. Common for canned goods or die-cut boxes.

  • C-Flute (4.0mm): The industry standard for regular shipping cartons (RSC). It offers excellent stacking strength and cushioning.
