Specifying PP strap (polypropylene strap) correctly is essential for packaging performance and cost efficiency. This guide covers the key specification parameters: width (5–19mm), thickness (0.35–0.80mm), break force (45–230kg), surface finish, and roll dimensions. Understanding how each parameter affects equipment compatibility, load security, and total cost helps procurement professionals specify the right strap for their application. According to industry standards, the correct specification reduces downtime, improves load stability, and optimizes material costs.
