PET strap (polyester strap) has a recommended storage life of 18–36 months under proper conditions. Temperature, humidity, UV exposure, and packaging integrity all affect how long PET strap maintains its performance.

Core dimensions are among the most overlooked specifications when buyers select PET strap (polyester strap) for automatic strapping operations. A strap that meets all mechanical requirements—correct width, thickness, and break force—will still cause feeding problems if its core size does not match the strapping head dispenser. Core inner diameter, roll width, and roll outside diameter must all be compatible with the machine's spindle and unwinding mechanism. This guide explains PET strap core dimensions, how they affect automatic strapping head performance, and how to verify compatibility before purchase.

The tensile strength of a PET strap typically ranges from 160 to 635 kilograms, depending on its dimensions and manufacturing quality. This measurement represents the maximum force the polyethylene terephthalate strapping can withstand before breaking, making it a crucial factor for procurement mana

Matching PET strap to your automatic strapping machine requires attention to width, thickness, core size, and surface finish. This guide covers key compatibility factors, common issues, and selection tips to ensure smooth operation and reliable load security.
