The strength of any strapping depends on its thickness and the materials made from. Our strapping has been tested for lightweight use up to 24kg or a large suitcase full, per strand. Most packages sent by courier or mainstream delivery service, weigh less than this. So there is no point using heavyweight strapping and a complex set of tools to pack it together. The table below shows the strength of the strapping we have. Our strapping is also reusable. You carefully unbuckle it and away you go! Thickness (non exhaustive) Tension rating About the same as... 8mm 30N A brick 10mm 45N A bloated pet cat (please don't test this) 12mm 177N A 5 year old (don't test this either!) 16mm 205N An SUV tyre No animals or humans were harmed in the making of this table
