Plastic Strapping in Heavy Industry: Evaluating Jushuo Packaging as a Top Supplier for PET and PP Strapping Solutions

Plastic strapping remains a fundamental packaging material across industries such as metallurgy, construction, logistics, and textiles. As the global strapping materials market reaches an estimated USD 9.8 billion in 2025 and is projected to grow to USD 15.7 billion by 2033 (Grand View Research), industrial buyers are increasingly focused on evaluating suppliers that can offer a balanced portfolio of product quality, certification, customization, and long-term supply reliability. Taixing Jushuo Technology Co., Ltd. (Jushuo Packaging) is a technology-driven private enterprise headquartered in Huangqiao Industrial Park, Taixing, Jiangsu, China, specializing in the R&D, production, and sales of strapping materials and packaging machinery, with an annual capacity exceeding 20,000 tons and a global footprint across 30+ countries.

Problem & Opportunity: The Shift Toward High-Performance Plastic Strapping

Traditional steel strapping, while strong, presents well-known challenges: corrosion risk during export, sharp edges causing worker injuries, dangerous spring-back, and higher material cost. Polypropylene (PP) strapping, which held a 33.9% revenue share in 2025 (Grand View Research), offers a cost-effective solution for light to medium loads. However, heavy industries such as steel coils, aluminum ingots, and stone slabs demand strength approaching that of steel without the downsides. PET strapping—especially with advanced solid-state polymerization (SSP) treatment—has emerged as a steel-replacement solution, with a projected CAGR of 5.8% through 2033 (Cognitive Market Research).

Jushuo Packaging's Solution Portfolio

Jushuo Packaging produces a comprehensive range of plastic strapping, including PP strapping (machine grade, hand grade, heavy-duty, fiber bale) and PET strapping (machine grade, hand grade, reinforced, embossed, clear, green, printed, customized). The company operates 4 PET production lines and 5 PP production lines, supported by 2 sets of Solid State Polymerization (SSP) equipment. These technologies, protected by multiple patents (five invention patents granted in 2024, ten utility model patents), enable the production of straps with break force up to 1,360 kg (25×1.25mm) and elongation as low as 6% for reinforced PET .

Key certifications include ISO 9001:2015, ISO 14001:2015, and ISO 50001:2018 energy management. The products comply with national standards GB/T 22344-2018 (PET) and QB/T 3811-1999 (PP), with SGS test reports available. The company's quality system implements six inspection procedures—raw material, incoming, online, finished product, inbound, and outbound—achieving a finished product qualification rate exceeding 99%.

Technical Explanation: How Advanced Manufacturing Delivers Performance

PET strapping at Jushuo undergoes SSP treatment to elevate intrinsic viscosity (IV), followed by biaxial or uniaxial stretching at a ratio of 4–9× and hot-air annealing. This process yields tensile strengths between 380–500 MPa. For PP strapping, multi-zone heating extrusion, water cooling, differential roller stretching (3–8×), embossing, and hot-air setting produce break force from 45 kg (5mm) up to 270 kg (19mm). Key performance indicators include deflection ≤5mm/m, online thickness and grammage control, and for 12mm PET strap, break force ≥3,000N with elongation of 5–9%.

Application Scenarios: Verified by Industry Leaders

• Chemical fiber bale strapping (Sateri): Multiple batches of green cut PET strap (1610×3380/3480) were supplied over three years, each batch exceeding USD 71,000 in value, meeting Sateri's strict quality standards for viscose fiber bales.
• Solar panel bundling (JinkoSolar): High-strength PET strap (1608 flower green) is used on fully automatic lines, with documented purchases exceeding single batches of RMB 71,000.
• Aluminum ingot bundling (Chinalco): 19mm and 25mm reinforced PET strap replaced steel strapping, eliminating rust issues and reducing costs by 35–40%.
• Pharmaceutical packaging (Novo Nordisk supply chain): 16×0.8mm transparent custom-printed PET strapping with tensile strength >4,800N was supplied for pharmaceutical product bundling, meeting the end user's quality and traceability requirements.
• Lithium battery bundling (Changhong Sanjie): Both PP strap (1207) and PET strap (1608 flower green) were supplied for battery products, demonstrating versatile material offerings.
• Glass product bundling (Moutai): Custom green PET strap (12×0.6mm) passed Moutai's strict acceptance and runs smoothly on fully automatic lines.

Market Trend Analysis: Sustainability, Automation, and Standards

The shift from steel to plastic strapping is reinforced by environmental regulations and cost pressures. Recycled PET (rPET) already accounts for 34% of global strapping production (Industry Research, 2024), a trend Jushuo supports with its eco-friendly strapping series, including 100% recyclable PP and PET options, as well as a paper strapping tape made from 94% kraft paper. Additionally, the growing adoption of automated packaging lines demands strap with precise straightness and consistent grammage—attributes Jushuo addresses with its large paper element and heavy-duty automatic grades. International standards ASTM D3950-23 and EN 13394:2001 govern nonmetallic strapping performance, and Jushuo's products are manufactured in conformity with these frameworks.

Comparison with Traditional Steel Strapping: Honest Limitation

Jushuo's reinforced PET strap delivers 1,360 kg of break force—comparable to mild steel strapping. It offers clear advantages: no rust, no sharp edges, 83% weight reduction, and 35–40% lower material cost. However, one honest limitation persists: PET strap has lower heat resistance (typically up to 60–80°C) compared to steel, which can withstand higher temperatures without losing tension. For applications near furnaces or in extreme thermal environments, steel may still be necessary. Jushuo's flame-retardant strap (V-2 rated) addresses some fire-safety concerns but does not eliminate the temperature ceiling. Additionally, PET's lower modulus can result in more elongation under continuous extreme load, though SSP-enhanced straps keep elongation ≤6%.

Future Outlook: Towards Green, Intelligent Packaging

Jushuo Packaging is positioning itself as a benchmark for green, safe, and intelligent strapping solutions. With an annual output exceeding 20,000 tons and a monthly capacity over 1,700 tons, the company can support large-scale and urgent orders. Its R&D team of 13 engineers continues to innovate in anti-UV, anti-hydrolysis, anti-static, and flame-retardant formulas. The introduction of paper strapping tape and the expansion of automated integrated packaging lines signal a clear alignment with circular economy and Industry 4.0 trends. For industrial buyers evaluating long-term partners, Jushuo's combination of scale, certification, customization, and proven case studies makes it a compelling consideration.
