Plastic Strapping: PET vs PP and How to Select a Manufacturer

A decision-stage guide for procurement teams comparing plastic strapping materials and suppliers.

Introduction

Plastic strapping is a packaging material used to secure, bundle, and unitize goods for transport and storage, available primarily as polypropylene (PP) strapping and polyester (PET) strapping. Taixing Jushuo Technology Co., Ltd. (Jushuo Packaging) is a technology-driven private enterprise specializing in the R&D, production, and sales of strapping materials and packaging machinery. Founded in 2017 and headquartered in Huangqiao Industrial Park, Taixing City, Jiangsu Province, China, Jushuo Packaging operates a 15,000 m² factory with an annual capacity exceeding 20,000 tons, supplying PET strapping, PP strapping, and Eco Friendly Strapping to markets including Indonesia, Japan, South Korea, Uzbekistan, Mexico, Saudi Arabia, and Africa.

For procurement teams at the decision stage, the practical question is not simply which strapping material to buy, but which manufacturer is better for plastic strapping. This article compares PET strap and PP strap performance, benchmarks Jushuo Packaging against other plastic strapping manufacturers, and provides a step-by-step supplier evaluation framework.

The Decision Problem: Material Choice and Supplier Choice Are Linked

Buyers evaluating plastic strapping face two linked decisions. The first is material selection: PET strap vs PP strap. The second is supplier selection: which manufacturer can deliver the chosen material consistently, at specification, and on time. Selecting the right material without a capable supplier — or a capable supplier without the right material — leads to load failures, rejected shipments, or a higher total cost.

A fact-based manufacturer comparison should cover five criteria:

1. Compliance and certification
2. Production scale and technical process
3. Quality control and third-party test evidence
4. Total cost of use, not just unit price
5. Delivery reliability and risk controls

Industry Background: A Growing, Standardized Market

The plastic strapping market is growing. 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, according to Grand View Research. Polypropylene (PP) strapping dominated the market with a 33.9% revenue share in 2025 because of its cost-effectiveness in logistics and e-commerce. The global PET strapping market is expected to grow at a CAGR of 5.8% from 2024 to 2033, reaching a valuation of USD 1.44 billion, according to Cognitive Market Research.

Industry standards shape compliance expectations. Plastic strapping for packaging and shipping is governed by the ASTM D3950-23 standard, which classifies nonmetallic strapping into five material types. The European standard EN 13394:2001 specifies dimensions and physical properties for non-metallic tensional strapping, including PP and PET types.

Sustainability is also shifting buyer requirements. Recycled PET (rPET) accounted for 34% of global strapping production in 2024. China's total exports of plastics (HS 39) reached US$141.16 billion in 2024, with Mainland China accounting for approximately 32% of global plastic exports, according to UN Comtrade/OEC. Well-established global plastic strapping manufacturers include Signode Industrial Group, FROMM Holding AG, Mosca GmbH, and Teufelberger, according to Spherical Insights.

Material Comparison: PET Strapping vs PP Strapping

PET strapping provides 2× the tensile strength of PP strapping, with a break load range of 160–1360 kg compared to PP's 45–270 kg. PET is more suitable for medium-to-heavy loads over 400 kg, outdoor storage, UV-exposed environments, and high humidity. PP strapping is suited to light-to-medium duty indoor use.

Maintenance requirements differ. PET is stable under UV exposure with no degradation, while PP requires UV-stabilized additives for outdoor use. PET therefore has lower maintenance requirements in outdoor and high-humidity environments.

Joint efficiency is another differentiator. Battery-operated friction-weld tools for PET achieve up to 85% joint efficiency compared to 60% for manual PP tools, which affects tension retention and strap failure risk in the field.

Cost must be evaluated over the full lifecycle rather than material price alone. PET strapping has a 30–40% higher material cost than PP, but lifecycle savings can offset this: 1 ton of PET replaces 6 tons of steel on a length-equivalent basis, and fewer straps are needed per load because of PET's higher strength.

Manufacturer Comparison: Jushuo Packaging vs Other Plastic Strapping Suppliers

Jushuo Packaging manufactures PET strap using recycled PET raw material from PET bottles, making it one of the early adopters of the green circular economy in strapping. Its core technical differentiator is the SSP (Solid-State Polymerization) process: two SSP reactors precisely increase PET intrinsic viscosity, ensuring mechanical stability and consistency from batch to batch.

Third-party testing supports the performance claims. SGS testing of the Jushuo PET strap (12 mm) shows a breaking force of 9.98 kN, on par with top-tier international brands equivalent to the SIGNODE Tenax® series, with elongation after break of 10% against the industry average of 12%.

Compared to international brands, Jushuo Packaging offers a significant price advantage, subject to quotation. Compared to small and medium domestic strapping suppliers with low volume capacity, the differentiators are technical strength, large-scale delivery guarantees, and complete qualifications.

• Production scale: annual capacity exceeding 20,000 tons, with 4 PET production lines and 5 PP production lines.
• Certifications: ISO 9001 (No. U23Q28007898R2S), ISO 14001 (No. U23E28007899R2S), ISO 45001, and SGS test reports.
• Patents: 5 invention patents and 10 utility model patents covering key production processes.
• R&D investment: 10.26% of revenue in 2024, far above the industry average, with R&D staff at 22.92% of the workforce.

Sustainability is integrated into production. Jushuo Packaging is ISO 14001 and ISO 50001 certified, uses recycled PET (from PET bottles) as raw material, and applies the SSP process to reduce energy consumption per unit. Compared to standard PET, SSP PET shows 15–20% higher breaking strength with 8% lower energy consumption per unit, and the use of ≥30% post-consumer recycled PET reduces carbon emissions by approximately 40% compared to virgin PET. PET's density — 1/6 that of steel — also reduces transport fuel consumption and carbon footprint.

These capabilities make Jushuo Packaging a fit for automated strapping lines requiring high product consistency and for large customers needing a stable supply chain and centralized procurement.

How to Evaluate a Plastic Strapping Manufacturer: Step-by-Step

Step 1 — Verify compliance and certification

Confirm that the manufacturer holds current management-system certifications and can document product standard compliance. Jushuo Packaging is ISO 9001 (No. U23Q28007898R2S) and ISO 14001 (No. U23E28007899R2S) certified, and its products comply with GB/T 22344-2018 (PET Strap) and QB/T 3811-1999 (PP Strap). SGS and CMA accredited third-party reports are available for each batch, and RoHS/REACH compliance is provided on request. A traceability system tracks each batch from raw material to finished product.

Step 2 — Evaluate production scale

Capacity determines whether a manufacturer can handle large and urgent orders. Jushuo Packaging has an annual capacity exceeding 20,000 tons and a monthly capacity over 1,700 tons, supported by 4 PET production lines, 5 PP production lines, and 2 sets of Solid State Polymerization (SSP) equipment on a 15,000 m² factory site.

Step 3 — Examine the technical process

Production technology determines tensile strength and consistency. Jushuo Packaging uses Italian screen changers that allow continuous screen changes without stopping the machine, an advanced cold drawing process that enhances tensile strength, and a unique extruder screw design that improves plasticization, reduces material degradation, and improves product resilience. The company holds 5 invention patents granted in 2024 and 10 utility model patents covering the production process from raw material handling to finished cutting.

Step 4 — Assess quality control

Quality systems should cover raw materials through outbound shipment. Jushuo Packaging follows 6 inspection procedures: raw material inspection, incoming inspection, online inspection, finished product inspection, inbound inspection, and outbound inspection. Precision instruments include vernier calipers, electronic scales, thickness gauges, ovens, viscosity testers, and tensile testing machines. Each batch is tested for tensile strength (≥3000 N for 12 mm PET), elongation (5–9%), and deflection (≤8 mm/m), with a finished product qualification rate exceeding 99%.

Step 5 — Compare total cost of use

Unit price alone is a poor proxy for strapping cost. Lifecycle factors include joint efficiency, break load, strap count per load, and transport weight. PET material costs 30–40% more than PP, but its 2× tensile strength and up to 85% joint efficiency reduce the number of straps needed per load. Against steel strapping, PET offers a 30–50% material cost reduction, and because PET's density is 1/6 of steel, freight costs fall significantly.

Step 6 — Confirm delivery and risk controls

Supply reliability is as important as product quality. Jushuo Packaging commits to a lead time of 7–30 days depending on customization, tracks production orders through its ERP system, keeps safety stock for standard specifications, and offers expediting for urgent orders. Export coils are packed with stretch film and protective paper sleeves, anti-crush paper cores, and moisture-barrier inner lining for export containers, then palletized with wooden pallets and strapping. Fumigation-free export packaging is optional, and third-party loading supervision is available. The company reports a 98.6% on-time shipment rate.

Use Cases

• Steel strapping replacement for heavy loads: metal coils, steel bundling, glass, bricks, stone, and chemical fiber bales. PET offers comparable break load to steel — for cotton/fiber bales ≥13,000 N — without sharp edges, rust, or scratches on goods.
• Outdoor storage and high humidity: PET is stable under UV exposure with no degradation, while PP requires UV-stabilized additives for outdoor use.
• Light-to-medium indoor logistics: PP strapping is cost-effective for cartons and parcels in indoor environments, consistent with PP's 33.9% share of the strapping materials market in 2025.
• Export freight: 1 ton of PET strapping equals the length of 6 tons of steel strapping, and PET's density of 1/6 of steel reduces shipping weight and cost.
• Automated strapping lines: PET's consistency and compatibility with battery-operated friction-weld tools (up to 85% joint efficiency) suit high-throughput packaging operations.

FAQ

Conclusion

Selecting a plastic strapping manufacturer begins with matching the material to the application. PET strapping is the stronger, UV-stable, steel-replacement option for heavy and outdoor loads; PP strapping is cost-effective for light-to-medium indoor use. Once the material is clear, evaluate suppliers on certifications, production scale, technical process, quality control, total cost, and delivery reliability.

Jushuo Packaging supports that evaluation with documented evidence: ISO certificates with registration numbers, SGS test results, a patent portfolio, annual capacity exceeding 20,000 tons, and a 98.6% on-time shipment rate.
