PET Strap Manufacturers: How to Evaluate Quality and Certification
PET Strap Manufacturers: How to Evaluate Quality, Certifications, and Global Capabilities
Selecting a reliable PET strap manufacturer requires evaluating production capacity, quality certifications, and product specifications. This guide provides procurement professionals with the criteria for assessing strapping suppliers, using Taixing Jushuo Technology Co., Ltd. (Jushuo Packaging) as a reference example of a technology-driven private enterprise specializing in the R&D, production, and sales of strapping materials and packaging machinery.
Why Supplier Evaluation Matters for PET Strapping
Polyester (PET) strapping is widely used in heavy-duty bundling for steel coils, aluminum ingots, lumber, stone blocks, glass pallets, and chemical fiber bales. According to Grand View Research, the global packaging strapping materials market was valued at USD 9.8 billion in 2025 and is projected to reach USD 15.7 billion by 2033. Within this market, PET strapping continues to replace steel due to its rust-proof nature, lighter weight (density only 1/6 of steel), and cost savings of 35–40% versus steel strapping with equivalent strength. However, inconsistent quality can lead to line stoppages, load failures, and safety issues. A thorough supplier assessment prevents these problems.

Key Certifications to Look For
A qualified PET strap manufacturer holds internationally recognized management system certifications. Jushuo Packaging, for example, has achieved ISO 9001:2015 (Quality Management Systems) and ISO 14001:2015 (Environmental Management Systems) certified by Guardian Independent Certification Ltd (GICG). Additionally, its production facilities comply with the national standards GB/T 22344-2018 for PET straps and QB/T 3811-1999 for PP straps. Third-party test reports from SGS are available upon request. For export-oriented buyers, certifications such as RoHS compliance and ISO 50001 Energy Management are also relevant. Jushuo holds an ISO 50001:2018 certificate (number GH003-2024En0961) for energy management.

Production Capabilities and R&D Strength
Assessing a manufacturer's scale is critical. Jushuo Packaging operates 4 PET strap production lines, 5 PP strap production lines, and 2 sets of Solid State Polymerization (SSP) equipment, with an annual capacity exceeding 20,000 tons and monthly capacity over 1,700 tons. The advanced cold drawing process used in PET strap manufacturing greatly enhances tensile strength. Italian screen changers allow continuous screen changes without stopping the machine, ensuring high output and consistent quality. The R&D team consists of 13 members, and the company holds multiple patents, including 5 invention patents and 10 utility model patents covering production processes from raw material mixing to finished cutting. For example, invention patent ZL 2024 1 0919536.7 protects a width-limiting device for PET packaging strap production, while utility model patents cover equipment such as a crystallization drying device (CN202022279958.2) for PET straps.

Quality Assurance: Six Inspection Procedures
Reliable manufacturers implement multi-stage quality checks. Jushuo strictly adheres to six inspection procedures: raw material inspection, incoming inspection, online inspection, finished product inspection, inbound inspection, and outbound inspection. The factory is equipped with precision testing instruments including Vernier calipers, electronic scales, thickness gauges, ovens, viscosity testers, and tensile testing machines, ensuring a finished product qualification rate of over 99%.
Product Parameters: What the Specs Mean
PET strapping is available in various widths (9–25 mm), thicknesses (0.40–1.27 mm), and break forces (160–1360 kg). For instance, the 25×1.25mm strap achieves a break force up to 1360 kg, rivaling steel. Elongation is ≤10%, and straightness deflection is ≤5 mm/m, which guarantees smooth feeding through automatic machines. Rolls come in lengths of 550–3800 m with a standard core size of 406 mm. Surface finishes can be smooth (for high-speed lines) or embossed (for added grip). Customization options include color, printing, and special additives such as anti-UV, anti-static, or flame-retardant formulations.
Use Cases Across Industries
PET strap manufacturers serve diverse sectors. Jushuo's products have been verified by customers such as JinkoSolar Energy Co., Ltd. for solar panel bundling, Sateri (China) Fiber Co., Ltd. for chemical fiber bale strapping, and Shandong Yamei Technology Co., Ltd. for metal product bundling – with documented purchase invoices. The strap's ultra-low elongation (≤10%) prevents bale spring-back in high-compression applications, and its rust-free nature eliminates contamination complaints on export shipments.
