Good quality packaging is critical to protecting your shipment during transportation. BOB provides a range of packaging supplies from DHL that are tried and tested. For times that available box sizes do not fit a shipment's needs, here are some general guidelines.


External Packing Materials

Parcel

Material
  • Use only high quality corrugated cardboard boxes for parcels. For fragile or heavy items, use double-wall or tri-wall boxes.
Strength
  • Locate the manufacturer stamp which tells you information about the construction type and strength of a box.
  • Refer to the box specifications below to select suitable packaging for the weight of your shipment.
Size
  • Choose the right size for the content being shipped. Under-filled boxes may collapse and over-filled boxes may burst.

Remarks:

  • Burst-Test (aka Mullen Test) is the force of pounds per square inch required to rupture or burst the side of a corrugated box. The result indicates the box's ability to withstand external or internal forces, and how the box will contain its contents during rough handling.
  • Edge-Crush-Test (ECT) measures the stacking strength of corrugated cardboard boxes or fiberboard. A finished box's compression-strength is defined by the amount of force that is needed to crush the cardboard by standing it on its edge.


Flyer Bag

Strength
  • To avoid splits or tears, do not exceed 4 kg per bag.
  • DHL Flyer Bags are designed to stretch at least 35 cm prior to failure and can hold 30% more weight at the seam.
