If you’re looking for durable and reliable packaging solutions, chances are you’ve come across PET straps.one of the first questions ask is: What size are PET straps, and which size is right for my packaging needs? This article will walk you through everything you need to know—from dimensions and applications to how to identify high-quality PET straps, and finally, why choosing us as your supplier ensures peace of mind.
What Is a PET Strap?
A PET strap (polyester strapping) is a strong, flexible, and weather-resistant packaging material made from polyester (PET). It is designed to hold products securely during storage and transportation. Unlike steel strapping, PET straps are safer to handle, resistant to rust, and often more cost-effective.
Key benefits of PET straps include:
High tensile strength to secure heavy loads.
Shock absorption during transport.
Resistance to UV rays and weather conditions.
Compatibility with both manual strapping tools and automatic strapping machines.
