Looking for postal packaging boxes to maximise the Royal Mail small parcel size limit of 450 x 350 x 160mm?

The E5-SP cardboard box is seriously strong with a Box Compression Test Strength (BCT) of 1540N. These small parcel cardboard boxes are over 20% stronger than the Industry Standard in the material strength Box Compression Test. In comparison, a standard single wall box will have a material strength of between 1190 and 1270N. (The Box Compression Test shows the force required to crush a box with a size of 400x300x200mm.)

Perfect for packing up DVD players, grilling machines, sandwich toasters and many other retail items where your objective is to fit as much as possible into the Royal Mail, small parcel tariff. The Lil cardboard box is the world's first and only (still) range of boxes to boast:

  • Variable depth for all sizes deeper than 6 inches. Simply tear down the easy to use vari-depth perforation, fold the flaps and away you go!*
  • All of our Lil cardboard boxes are manufactured using FSC® certified material for environmental sustainability.
  • BCT stamped to prove it's over 20% stronger than industry standard* (material strength Box Compression Tested)

Sturdy single wall postal packaging boxes. Flat packed - make them up by taping the flaps. More attractive than a plain unprinted stock box.
