PET vs PP vs Composite Cord Strap: The Definitive Selection Guide for European Industrial Buyers

The Decision That Matters: Choosing the wrong strapping material costs European industrial operations an average of 8–15% more in total packaging cost than the correct material — through machine jams, transit damage, re-strapping labor, and injury liability.

Strapping material selection is the most consequential specification decision in industrial packaging. Choose correctly and your operation runs at optimal cost, safety, and compliance. Choose incorrectly and you pay the difference every day in machine downtime, damage claims, re-strapping labor, and injury incidents. This guide provides the definitive technical and commercial framework for European industrial buyers to make the right choice — every time.

1. The 30-Second Answer

The ranges above overlap intentionally — the 500–1,400 Kgf range is where both PET strapping and cord strap are technically viable. In this range, the decision depends on secondary factors: machine availability, re-tensionability requirement, surface safety priority, and whether DNV certification is required. The sections below provide the detail needed to make the right call in every case.

3. PP Strapping — When to Use It

PP (Polypropylene) strapping is the world's highest-volume strapping material. It is the correct choice for light-to-medium load applications where machine speed and cost per strap are the primary drivers.

Optimal applications for PP strapping:

• Carton sealing and bundling on high-speed production lines (up to 60 straps/min)
• E-commerce and parcel distribution — light loads under 50 Kgf
• FMCG multi-pack bundling — beverages, food, consumer goods
• Textile and apparel export cartons — light, surface-sensitive loads
• Newspaper and magazine bundles — where marking must be minimized
• Any application under 200 Kgf per strap point in a controlled indoor environment

When NOT to use PP strapping: Heavy pallets above 200 Kgf per strap point, outdoor or cold chain applications below -10°C, extended UV exposure, multi-modal transit requiring dynamic load retention, or any application where strap failure would create a safety hazard.

4. PET Strapping — When to Use It

PET (Polyethylene Terephthalate) strapping is the professional standard for heavy industrial packaging across European logistics. Its combination of high break strength, excellent elastic recovery, and machine compatibility makes it the optimal choice for the majority of heavy-duty applications.

Optimal applications for PET strapping:

• Heavy industrial pallets — construction materials, metals, machinery components
• Metal coils, pipes, and extrusions — 19–32mm, 500–1,400 Kgf
• Cotton and fiber bales — compression retention and recovery
• Multi-modal transit (road + sea + rail) — elastic recovery maintains tension through load settling
• Cold chain logistics — rated to -30°C
• Automotive parts and components — surface-safe, no rust contamination

When NOT to use PET strapping: Light carton sealing applications where PP is more cost-effective, applications above 1,400 Kgf requiring DNV certification, or applications requiring re-tensionability during transit.

5. Composite Cord Strap — When to Use It

Composite cord strap is the direct modern replacement for steel strapping and the highest-performance strapping solution for heavy cargo securing. It is the only strapping material that can be re-tensioned after application — a critical capability for sea freight and multi-modal transit where load settling is unavoidable.

Optimal applications for composite cord strap:

• Direct replacement for steel strapping — eliminates snap-back injury risk and rust staining
• Heavy machinery and capital equipment (CNC machines, generators, turbines)
• Sea freight and international container lashing — DNV certified system strength up to 2,680 Kgf
• Out-of-gauge (OOG) and project cargo
• Glass panels, marble slabs, and surface-sensitive heavy cargo
• Cylindrical cargo (twisted variant) — pipe bundles, rolled materials
• Any application requiring re-tensioning during transit
• Safety-critical applications requiring documented lashing system strength

6. The Decision Flowchart — 5 Questions

1. What is the load weight per strap point? — If under 200 Kgf: PP. If 200–1,400 Kgf: PET. If over 1,000 Kgf or replacing steel: Cord Strap.
2. Is re-tensionability required during transit? — If yes: Cord Strap only. PP and PET cannot be re-tensioned after application.
3. Is DNV certification required (sea freight)? — If yes: Cord Strap (Greenstrix DNV certified). PET and PP are not DNV certified for maritime lashing.
4. Is this a high-speed automated machine application? — If yes and load is under 200 Kgf: PP. If yes and load is 200–1,400 Kgf: PET. Cord Strap is not machine-applied.
5. Is the operating temperature below -10°C? — If yes: PET (rated to -30°C) or Cord Strap (rated to -40°C). PP is not recommended below -10°C.
