Plastic Strapping for Heavy Industry: Matching Application Scenarios with the Right Material – A Jushuo Packaging Guide

The global packaging strapping materials market, valued at USD 9.8 billion in 2025, is projected to reach USD 15.7 billion by 2033, with polypropylene (PP) strapping capturing a 33.9% revenue share due to its cost-effectiveness in logistics and e-commerce, and PET strapping expected to grow at a 5.8% CAGR. For industrial buyers evaluating strapping solutions, the choice between PP and PET—and the specific performance additives required—depends entirely on the application scenario. This guide examines how Taixing Jushuo Technology Co., Ltd. (Jushuo Packaging), a technology-driven private enterprise founded in 2017 and headquartered in Taixing, Jiangsu, China, addresses these diverse needs through its full portfolio of plastic strapping products.

The Challenge: One Size Does Not Fit All

Different heavy industries place unique demands on strapping materials. Steel and metal processors struggle with rust contamination and worker injuries from steel strap spring-back. Brick manufacturers face pallet collapse when ordinary straps relax under prolonged UV exposure. Solar panel producers require electrostatic discharge (ESD) protection and fire safety compliance for ocean shipping. Glass makers demand a smooth, burr-free surface to avoid scratches. Logistics operators prioritize ease of use and cost per carton. A generic PP or PET strap cannot satisfy all these requirements.

Jushuo Packaging's Solution: Customizable Plastic Strapping for Every Scenario

Jushuo Packaging manufactures both PP strapping (5–19mm width, break force 45–270kg) and PET strapping (9–25mm width, break force 160–1360kg) with an annual capacity exceeding 20,000 tons. The company's in-house R&D and solid-state polymerization (SSP) technology allow precise customization of additives: anti-UV, anti-static, flame-retardant, anti-hydrolysis, and embossed finishes. This enables a single supplier to serve multiple industries with tailored solutions.

Technical Foundation: SSP and Cold Drawing

Jushuo's manufacturing process begins with SSP to enhance the intrinsic viscosity (IV) of PET resin, followed by biaxial/uniaxial stretching (4–9×) and hot-air annealing, achieving tensile strength of 380–500 MPa. The cold drawing process improves molecular orientation, delivering ultra-low elongation (≤6% for reinforced PET) and superior straightness (deflection ≤5mm/m). For PP, multi-zone heating extrusion, water cooling, differential roller stretching (3–8×), embossing, and hot-air setting ensure consistent grammage and heat-seal performance. Italian screen changers allow continuous operation without machine stoppage.

Industry-Specific Scenarios and Recommended Products

Brick Manufacturing (Outdoor Storage, UV Exposure)

Brick stacks stored outdoors require UV-resistant PET strapping. Jushuo's PET strap with UV stabilizer retains ≥85% strength after 1,000 hours QUV testing, stays tight after one month outdoors, and reduces stack collapse by >80%. Typical specifications: 16mm width, breaking force ≥7,500N, elongation ≤5%. Customers include Conch Cement Brick Industry and Sinoma International Engineering Co., Ltd.

Photovoltaic (Solar Panels, Battery Packs)

Solar module packaging demands anti-static (surface resistivity 10⁶–10⁹Ω) and flame-retardant (V-2 rating, oxygen index ≥26%) PET strap. Jushuo's customized PET strap reduces ESD complaints by 80% and passes overseas fire inspections. A key client, JinkoSolar Energy Co., Ltd., has placed single purchases of 3,600 rolls (RMB 540,000).

Metal Processing (Steel Coils, Aluminum Ingots)

To replace steel strapping, Jushuo's H-series reinforced PET strap delivers break force up to 1,360kg (25×1.25mm) with elongation ≤6%, costing 35–40% less than steel while eliminating rust and safety hazards. Shandong Yamei Technology reported complete elimination of rust issues and 40% cost reduction.

Glass & Ceramics (Fragile Surface Protection)

Jushuo's PET strap with smooth, burr-free surface prevents scratches on glassware. Custom green PET strap (12×0.6mm) supplied to Guizhou Moutai Distillery Group's glass subsidiary achieved zero scratches and increased automatic line efficiency by 20%.

Logistics & E-commerce (Cost-Effective Manual Bundling)

For semi-automatic machines, Jushuo's PP strap offers deflection ≤5mm/m, break force ≥1,400N (12mm), and 20–30% lower price than imported alternatives. The soft design facilitates manual tensioning and knotting.

Market Trend Analysis

The shift from steel to plastic strapping is driven by sustainability regulations and cost pressure. Recycled PET (rPET) now accounts for 34% of global strapping production. Jushuo's Eco Friendly Strapping series, including flame-retardant and high-strength chemical fiber variants, supports circular economy goals. Automation in packaging lines further demands precise grammage and straightness, which Jushuo's machine-grade products provide.

Comparison with Traditional Solutions

Compared to steel strapping, PET plastic offers 35–40% cost savings, elimination of rust and spring-back hazards, and 83% weight reduction. Compared to standard PP, Jushuo's high-strength PP delivers 30–50% higher break force at a modest price increase. An honest limitation: standard PET becomes brittle below -10°C; Jushuo addresses this with a cold-chain C-series that remains flexible down to -50°C, but that is a specialized product.

Future Outlook

As industries demand lighter, safer, and more sustainable packaging, Jushuo Packaging continues to invest in SSP technology and additive development. The company's five invention patents (granted 2024) and ISO 9001/14001 certifications position it as a reliable partner for global buyers. With a 98.6% on-time shipment rate and 30% export ratio to markets including Japan, South Korea, Mexico, and Saudi Arabia, Jushuo is scaling to meet growing needs.

FAQ

What are the key differences between PP and PET strapping?

PP strapping is lightweight, cost-effective, and suitable for light to medium-duty bundling with elongation ≤20%. PET strapping offers steel-comparable strength (up to 1360kg break force), ultra-low elongation (≤10%), and rust resistance, making it ideal for heavy loads and export containers.

Can PET strapping replace steel strapping for heavy loads?

Yes. Jushuo's reinforced PET strap achieves break force up to 1360kg, matching high-grade steel, while weighing one-sixth as much and eliminating rust and spring-back hazards. Typical cost savings are 35–40%.

What customization options are available for special applications?

Jushuo offers custom width (5–25mm), thickness (0.35–1.27mm), color, custom printing, and performance additives including anti-UV, anti-static (10⁶–10⁹Ω), flame-retardant (V-2), anti-hydrolysis, and embossed surface. Minimum order quantities are flexible.

Does Jushuo provide certifications and test reports?

Yes. Products comply with GB/T 22344-2018 (PET) and QB/T 3811-1999 (PP). The company is ISO 9001 and ISO 14001 certified, and SGS test reports are available upon request, including breaking force, elongation, and deflection data.

What is the lead time for custom orders?

Stock specifications ship within 7 days; custom formulations and printing typically require 15–20 days. Annual capacity exceeds 20,000 tons, ensuring fast response for large or urgent orders.
