PP Strapping: Core Material for Modern Packaging – Jushuo Packaging's Complete Portfolio

PP strapping, also known as polypropylene strap or PP band, remains the most widely used plastic strapping material in light-to-medium duty packaging due to its cost-effectiveness and versatility. With the global packaging strapping materials market projected to reach USD 15.7 billion by 2033 (Grand View Research, 2025), polypropylene strapping alone held a 33.9% revenue share in 2025, driven by its affordability and suitability for logistics, e‑commerce, and general manufacturing.

Problem / Opportunity

Despite its popularity, the performance of PP strapping varies significantly across suppliers. Poor straightness leads to frequent jams on automatic strapping machines, inconsistent thickness causes weak seals, and high elongation results in load loosening during transit. End‑users increasingly demand reliable, machine‑compatible, and customizable strapping that reduces downtime and supports sustainability goals.

Brand Solution: Jushuo Packaging

Taixing Jushuo Technology Co., Ltd. (Jushuo Packaging), established in 2017, specializes in R&D, production, and sales of strapping materials and packaging machinery. The company operates a 15,000 m² facility with an annual production capacity of over 20,000 tons, including 5 dedicated PP strap production lines. Its PP strapping portfolio covers widths from 5 mm to 19 mm, thicknesses from 0.35 mm to 0.90 mm, with break forces ranging from 45 kg to 270 kg. Products comply with QB/T 3811-1999 national standard and are manufactured under ISO 9001 and ISO 14001 certified systems. Third‑party SGS test reports are available upon request.

Technical Explanation

Jushuo's PP strap is produced through a rigorous process: multi‑zone heating extrusion → water cooling → differential roller stretching (3–8×) → embossing → hot‑air setting → automatic winding. This unidirectional stretching aligns molecular chains, delivering consistent tensile strength and low elongation (≤20% for standard grades, ≤15% for heavy‑duty and ≤12% for fiber bale grades). Key quality metrics include straightness deflection ≤5 mm/m, precise grammage tolerance (±0.05 g/m), and heat‑seal weld strength ≥80% of the base material. Italian screen changers enable continuous operation without stoppage, ensuring uniform thickness and high output.

The product line includes:

• Machine Grade PP Strapping (models JS05035-P to JS19080-P): Optimized for fully automatic and high‑speed semi‑automatic strappers. Smooth or embossed surface, heat‑seal optimized.
• Hand Grade PP Strapping (models JS500A-HP, JS600A-HP, etc.): Soft, rounded edges for manual tensioning and knotting; embossed surface prevents slip.
• Heavy‑duty PP Strapping (12 mm × 0.80 mm, break force up to 270 kg): Bridges the gap between standard PP and PET for medium‑heavy loads.
• Fiber Bale PP Strap (12 mm, high tensile, elongation ≤12%): Specifically formulated for high‑compression baling of chemical fibers and cotton.
• Colored, Translucent, Clear, and Custom Printed PP Straps: Support brand identification, barcode readability, and anti‑counterfeiting. Printing ink is RoHS compliant and abrasion‑resistant (≥500 cycles).

Application / Use-Case Scenarios

Jushuo's PP straps are deployed across numerous industries:

• Logistics & E‑commerce: 9 mm and 12 mm hand/semi‑auto straps used for carton bundling. Suzhou Qingyu Packaging reports reliable feeding and reduced jams on semi‑automatic machines.
• Food & Beverage: Transparent 12 mm machine grade straps maintain barcode readability on multi‑packs; custom printed straps used by Shuanghui Group and Kangshifu.
• Home Appliances: 12 mm × 0.80 mm heavy‑duty PP strap used by Gree on automatic lines for air‑conditioner cartons, reporting zero breakage.
• Chemical Fiber & Textile: Fiber bale PP strap (12 mm, high strength) adopted by Jiangsu Ruibang Technology and Xinjiang Xingtai Fiber for polyester and viscose bale strapping, eliminating bale spring‑back.
• Ceramic Tiles: 9 mm machine grade strap with deflection ≤3 mm/m ensures jam‑free operation on high‑speed tile lines (Marco Polo, Dongpeng).
• Pharmaceutical & Electronics: Custom printed PP straps with batch numbers and logos support GMP traceability; anti‑static or flame‑retardant variants available for new energy batteries.
• Construction Materials: PP straps for brick pallets and wood panel bundling, often combined with edge protectors.

Market Trend Analysis

The dominance of PP strapping is reinforced by its 33.9% revenue share in 2025 (Grand View Research). The PET strapping market is growing faster (CAGR 5.8%), but PP remains the preferred choice for cost‑sensitive, high‑volume applications. Increasing adoption of recycled PP (rPP) and custom printing aligns with brand sustainability and marketing goals. Jushuo's ability to offer recycled content, flame‑retardant additives, and UV‑resistant formulations positions it to capture these evolving requirements.

Comparison with Traditional Solutions

Compared to steel strapping, PP straps are rust‑proof, safe (no sharp edges or spring‑back), lightweight (density 0.91 g/cm³), and cost 35–50% less. However, PP does not match the tensile strength of steel or PET for extreme heavy loads (e.g., steel coils >2 tons). For such applications, Jushuo's PET strapping line is recommended. One honest limitation: standard PP strap is not suitable for prolonged outdoor UV exposure without anti‑UV additives, and its elongation (≤20%) is higher than PET (≤10%), making it less ideal for loads requiring ultra‑low stretch.

Future Outlook

As circular economy regulations tighten, the demand for recyclable and bio‑based strapping materials will accelerate. Jushuo is investing in solid‑state polymerization (SSP) technology for PET, while continuing to optimize PP production for higher strength and lower environmental footprint. Customization, including printed logos and anti‑static properties, will become standard as brands seek differentiation through packaging.

FAQ

What are the typical break forces of Jushuo's PP straps?

Break force ranges from 45 kg (5 mm × 0.35 mm) to 270 kg (19 mm × 0.80 mm). For example, 12 mm × 0.80 mm heavy‑duty grade delivers 180–270 kg.

Can PP straps be used on automatic strapping machines?

Yes. Machine grade PP straps (models JS05035-P to JS19080-P) have straightness deflection ≤5 mm/m and are optimized for heat‑seal welding, reducing jams in high‑speed automatics.

Are Jushuo's PP straps recyclable?

Yes. All Jushuo PP straps are 100% recyclable. The company also offers straps made with recycled PP content, RoHS compliant.

What is the elongation of PP straps?

Standard machine grade ≤20%; heavy‑duty grade ≤15%; fiber bale grade ≤12%. Lower elongation versions can be customized.

Do you offer custom colors and printing?
