Why Double-Wall?

  • Stronger by design: two corrugated mediums improve edge crush and stacking performance over single-wall.
  • Route-proof: better puncture resistance and corner integrity for e-commerce, 3PL, and palletized freight.
  • Brand and ops friendly: supply-chain barcodes, compliance marks, and sharp branding in one pass.

FAQs

Single-wall vs. double-wall: which should I choose?

Choose double-wall when you need higher edge crush and stacking strength, better puncture resistance, or longer supply-chain routes. Single-wall is efficient for lighter loads and short routes.

Can you print compliance marks and barcodes?

Yes. We can add box cert stamps, handling icons, and scannable barcodes or QR for WMS and 3PL needs.

How do we spec strength correctly?

Share weight, contents, and stacking height. We will propose flute, liner weights, and a target ECT/burst range to meet your route and warehouse conditions.
