PET Plastic Strapping

Updated: 2026-07-15

Overview

PET plastic strapping, or polyester strapping, is a high-performance packaging material derived from polyethylene terephthalate. It is engineered for heavy-duty applications where high tensile strength and durability are critical. Compared to PP (polypropylene) strapping, PET offers superior resistance to elongation under tension, making it ideal for securing heavy loads during transit or storage. The material's molecular structure provides inherent UV resistance and minimal moisture absorption, ensuring consistent performance in diverse environments. PET strapping is fully recyclable, aligning with modern sustainability goals in logistics and manufacturing industries.

Physical and Chemical Properties

PET strapping exhibits a unique combination of mechanical and chemical properties. Its tensile strength typically ranges from 500 to 1,200 kg/cm², outperforming steel strapping in weight-to-strength ratio. The material maintains flexibility at temperatures as low as -40°C without becoming brittle, while its heat resistance allows brief exposure up to 150°C without deformation. Chemically, PET is inert to most oils, greases, and dilute acids, though strong alkalis may degrade it over time. Unlike PP strapping, PET does not creep (gradually elongate) under constant tension, ensuring long-term load stability. The material's crystalline structure contributes to its excellent fatigue resistance during repeated handling.

Main Applications

In logistics, PET strapping secures palletized goods ranging from construction materials to consumer electronics. Its high tensile strength makes it particularly suitable for heavy bundles in the steel, timber, and paper industries, where loads exceeding 1,000 kg require secure containment. The strapping's UV resistance extends its use to outdoor storage and shipping containers. Construction applications include concrete pipe bundling and rebar stabilization, where the material's resistance to alkaline environments proves advantageous. PET strapping also replaces steel bands in automated packaging lines due to its compatibility with friction-weld sealers and reduced risk of product damage. Emerging uses include agricultural baling and marine cargo securing.

Safety and Storage

While PET strapping poses minimal health risks during normal handling, melted material (during heat-sealing) can release acetaldehyde vapors. Adequate ventilation is recommended in high-volume sealing operations. The material's smooth surface reduces friction burns compared to textured PP strapping, but cut-resistant gloves should still be worn during tensioning. Proper storage involves keeping coils in their original packaging until use to prevent UV degradation. Indoor storage at temperatures below 40°C prevents premature aging. Unlike steel strapping, PET does not require humidity control, but prolonged exposure to direct sunlight should be avoided even for UV-stabilized grades to maintain optimal mechanical properties.

B2B Procurement Guide

When sourcing PET strapping, specify the required breaking strength (typically 500–1,200 kg/cm²), width (commonly 9–15 mm), and thickness (0.5–1.5 mm). For outdoor applications, verify UV stabilization levels—premium grades offer up to 12 months of direct sunlight resistance. Consider pre-notched variants for easier tool-free hand tensioning. Bulk purchases (10+ metric ton orders) often qualify for 15–30% discounts. Leading manufacturers provide third-party certifications like ISO 9001 and ASTM D3950 compliance testing. For automated packaging lines, request samples to test compatibility with your sealing equipment. Eco-conscious buyers should inquire about post-industrial recycled content options, which can reduce costs by 10–20% while maintaining performance.
