PET strap (polyester strap) is a high-strength strapping material used across heavy-duty industrial applications where steel-like strength is required without steel’s drawbacks. With tensile strength up to 600 N/mm², excellent tension retention, and rust-free performance, PET strap is the preferred choice for steel coil bundling, cotton bale packaging, brick palletizing, lumber bundling, and heavy-duty cargo securing. This guide explores the key applications of PET strap, helping procurement professionals understand where and why this versatile material is specified.
