Choosing between PET strap (polyester strap) and steel strapping is one of the most consequential decisions in industrial packaging. PET strap offers up to 50% cost savings per foot, eliminates injury risks from sharp edges and snap-back, and provides superior tension retention as loads settle during transit. Steel strapping delivers maximum rigidity for extreme loads but carries hidden costs including higher labor requirements, rust contamination risks, and equipment wear. According to industry data, PET strap provides four times the linear footage per ton compared to steel, fundamentally changing the cost equation.

PP strapping (polypropylene strapping) is the most widely used strapping material for light to medium-duty packaging applications. Made from polypropylene resin through extrusion and stretching processes, PP strapping combines flexibility, cost-effectiveness, and ease of use. According to Signode, a leading strapping manufacturer, PP strapping is designed for palletizing, unitizing, bundling, carton closure and reinforcement

PET strap (polyester strap) is available in standard widths ranging from 9mm to 32mm, with common sizes including 12mm, 16mm, 19mm, 25mm, and 32mm. Width selection directly affects break strength, load distribution, and equipment compatibility. A 19mm PET strap typically delivers break forces of 450–550kg, while a 25mm strap can exceed 900kg—approaching steel strapping performance at significantly lower weight and cost.

PP strap (polypropylene strap) is available in standard widths from 5mm to 19mm, with common sizes including 5mm, 9mm, 12mm, 15mm, and 19mm. Width selection directly affects load distribution, break strength, and equipment compatibility. This guide explains the standard width options available, how to choose the right width for your application, and the performance implications of each size. Industry standards show that width determines strap performance in three critical areas: load distribution across package surfaces, break strength and load capacity, and equipment chute compatibility.

PET strap (polyester strap) and PP strap (polypropylene strap) are the two most common plastic strapping materials, yet they serve fundamentally different purposes. While PP strap offers flexibility and cost efficiency for light-duty packaging, PET strap delivers steel-like strength with low elongation, making it ideal for heavy loads, outdoor storage, and long-distance shipping. This guide explains what PET strap is, how it differs from PP strap in material properties and performance, and how to choose the right option for your specific application.

PP strap (polypropylene strap) is the most widely used strapping material for light to medium-duty packaging applications worldwide. This article answers two fundamental questions: what exactly is PP strap, and what is it used for? We explain how PP strap is manufactured—from polypropylene resin extrusion to molecular orientation that delivers strength and flexibility—and explore its primary applications across palletizing, bundling, carton closure, and e-commerce fulfillment. With width options ranging from 5mm to 19mm, thicknesses from 0.35mm to 0.8mm, and break forces from 45kg to 230kg, PP strap adapts to diverse packaging needs while offering cost-effective performance .

When buying packing materials for businesses, checking the quality of the polyester strap is a very important step that has a direct effect on how safe the loads are and how much it costs to run the business. High-quality PET polyester strap has a tensile strength that ranges from 180 to 1360 kg,

The backbone of countless automated systems around the world is polypropylene PP strap, which stands out when it comes to current packing efficiency. This strapping material, which is mostly made of polypropylene resin, a thermoplastic polymer,

PP strapping often has problems like breaking during tensioning, loads becoming loose over time because the material stretches, automatic strapping machines getting stuck a lot, and seal strength that isn't always consistent. Most of the time, these problems are caused by differences in the quality

Picking the right strapping material for heavy-duty box loads during storage and transport can mean the difference between damage that costs a lot of money and safe delivery. For procurement managers and warehouse operations heads who need reliable, low-cost ways to palletize big loads and a mix of
