CALIBER CORRUGATED

Engineered for zero-plastic transit.

We design custom corrugated dielines and high-tolerance flute profiles that protect heavy products through the entire shipping cycle using single-material cardboard alone. We eliminate plastic waste entirely while maintaining drop-tested durability.

Unboxing mechanics

We calibrate corrugated board thickness and flute density to match your exact product weight, ensuring maximum vertical stacking strength on the pallet without adding unnecessary volume.

Precision-cut dielines feature friction-lock tabs that secure the box frame under stress, eliminating the need for plastic tape and preventing adhesive failures in transit.

We engineer the physical opening sequence with integrated tear-strips and structural folds, ensuring your package arrives intact and opens cleanly without requiring knives or scissors.
