PP or PET strap
Polypropylene suits light and medium loads and is the everyday choice. Polyester holds higher tension and resists creep, which matters when a load will sit in a warehouse or a container for weeks and the strap has to still be tight at the far end rather than just tight on the day. Common widths run from around 9 mm to 19 mm depending on the head model, and width and gauge are matched to load weight and how stable the stack is.
