Work out strapping length instantly with clear inputs, formula shown and shareable results.
A vertical strap goes round the length and height, a horizontal strap round the length and width, and each needs about 250 mm extra for the seal, tensioner grip and overlap. Multiplying the average by the number of straps gives the consumption per load and hence loads per coil.
Strap length
Vertical = 2 x (length + height) + 250 mm; horizontal = 2 x (length + width) + 250 mm
Strapping under tension stores significant energy and can whip on release. Wear eye protection and use the correct cutter when opening strapped loads.
Two vertical straps for pallet-to-load locking is the minimum, plus horizontal straps every 400-600 mm of height for tall loads. Edge protectors are needed on compressible loads.
Polyester suits loads that settle, since it retains tension elastically. Steel suits rigid heavy loads needing very high break strength, but loses tension if the load compresses.
