Question 1

How do I choose the right box size?

Accepted Answer

The optimal box size minimises void fill (air space) while providing adequate product protection. Aim for no more than 20-30% void fill for eCommerce shipments. Our box size calculator suggests dimensions that fit standard pallet footprints and carrier size tiers to avoid dimensional weight penalties.

Question 2

What is packaging cost per unit?

Accepted Answer

Packaging cost per unit = (material cost + print cost + filling cost) / units per pack. Material cost depends on substrate, weight, and order quantity. Print costs amortise over run length. Filling includes labour, machinery, and consumables. Our calculator handles all three components.

Question 3

What makes packaging sustainable?

Accepted Answer

Sustainable packaging uses recycled or renewable materials, is itself recyclable or compostable, minimises material weight, eliminates unnecessary layers, and avoids mixed-material constructions that hinder recycling. Our scorer rates packaging across these dimensions and suggests improvement areas.
