Kangaroo Mailers facts:

  • The Kangaroo Mailer is cheaper to ship because it is smaller and weighs less for the same prescription shipment.
  • The Kangaroo Mailer is approved by UPS, USPS, and FedEx to be used as a shipping container without an outer corrugate carton.
  • A Kangaroo Mailer will always outlast a standard EPS product with equal amount ice, product, and identical test environment, because The Kangaroo Mailer inflates to remove all void inside the package, tightly holding the contents exactly as they were packed within a cocoon of memory foam, while the EPS product uses additional bubble wrap or paper to fill the empty space.
  • Empty space increases the influence of convection, reducing the duration of the frozen ice pack while increasing the likelihood to suffer early freeze damage.
  • Empty space allows the contents to shift in transit, possibly causing product damage or reduced duration.
  • The Kangaroo Mailer solution does not use any packing tape, void/loose fill, or boxes
