Project Overview
An Australian online retailer shipping 500,000 orders a month needed custom-printed mailers that survive Australia Post's network — with brand-level print quality, seasonal volume spikes and landed costs that work against domestic competitors.
Scope of Supply
- Poly mailers in 6 sizes, 2C brand print, 60 micron co-ex film
- Kraft paper mailers for the brand's plastic-free line
- Corrugated mailer boxes for multi-item orders
- Volume-spike planning across Black Friday and Christmas peaks
How We Executed
- Sorting-hub simulation testing: tumble and puncture tests on loaded mailers
- Print rub-testing to survive parcel conveyor contact
- Sea-freight inventory buffering so peak season never depends on air freight
Outcome
Transit damage on mailer-shipped orders fell below 0.4%, and the custom print survived network handling well enough that the brand dropped its inner-tissue program — a measurable cost saving per order.
What Australian Parcel Networks Do to Packaging (and How We Design For It)
Australia's parcel network imposes a durability profile most Northern-Hemisphere suppliers underestimate: parcels travel thousands of kilometers through automated sorting hubs, spend hours in hot delivery vans, and face some of the world's longest last-mile routes. We design for this network explicitly: mailer films are puncture and tumble tested against loaded simulation runs rather than empty-bag tests, adhesives are qualified for 40 °C+ vehicle temperatures so seals don't creep in summer, and print inks are rub-tested against conveyor contact. The second Australia-specific discipline is distance economics: at 500,000 orders a month, air-freighting packaging from China is a margin killer, so we buffer sea freight ahead of peak and size safety stock to the retail calendar. The result is a packaging program whose landed cost lets the brand compete with domestic suppliers on price while beating them on print quality.

Brands often respond to transit damage by adding packaging — more tissue, more void-fill, an outer box — when the cheaper fix is specifying the mailer correctly. This retailer's damage analysis showed the failures concentrated in two causes: punctures from box corners against 40-micron film, and seam creep in summer vans. Moving from 40 to 60 micron co-extruded film and upgrading the adhesive formulation eliminated both failure modes, and the damage rate dropped below 0.4% — better than the brand achieved with its previous double-packaging approach, at lower total cost per parcel. The general principle: measure your damage causes before adding packaging mass, because specification upgrades on the outer layer are almost always cheaper than material added inside it.
