Aluminum products—ingots, coils, profiles, and sheets—present packaging challenges that ordinary strapping cannot handle. Heavy weights, sharp edges, surface sensitivity, outdoor storage, and ocean transit demand strapping with high tensile strength, low elongation, rust-free performance, and weather resistance.

PP strapping (polypropylene strapping) is available in thicknesses from 0.35mm to 0.80mm, with each range suited to specific load requirements, equipment types, and printing needs. Thinner straps (0.35–0.45mm) serve light cartons and e-commerce packaging, while thicker options (0.55–0.80mm) handle pharmaceutical cartons, pallet loads, and industrial bundling.

PET strap (polyester strap) has become the modern alternative to steel strapping across industries ranging from steel processing to cotton ginning. It offers steel-like tensile strength at one-sixth the weight, eliminates injury risks from sharp edges and snap-back, and resists rust and corrosion.
