Which Strapping Belt is Best for High-Stress Packaging: PP or PET?
2025-08-07
Addressing Packaging Challenges in Modern Logistics
Common Risks of Storage and Transportation
In today’s globalized supply chain, packaging must withstand long-distance shipping, handling multiple times, and exposure to the elements. Among the perils are moisture exposure, dust contamination, transit movement, and stacking pressure that can void product integrity. For light or fragile products like ceramics or machinery, packaging breakdown can result in costly damage or downtime.
The Application of Strapping Belts in Cargo Securing
Strapping belts are the first choice for stabilizing and securing merchandise in transportation and storage. For tying up cartons or pallet palletizing, an adequate strapping material ensures security, reduces loss, and enhances handling productivity. The choice between PP (polypropylene) and PET (polyester) strapping belts depends on the specific needs of the cargo as well as transportation conditions.

Understanding the Core Types of Strapping Belts
Features and Applications of PP Strapping Belts
Material: Polypropylene (PP)
PP strapping bands are made primarily from polypropylene resin—a lightweight plastic known for its good plasticity, high tensile strength, bending resistance, low density, and ease of use.
Key Characteristics: High Flexibility, Bright Colors, Anti-Slip Texture, Cost-Effective
Packing straps have good plasticity, strong breaking tension, bending resistance, low density, and good tensile impact properties. Clear surface pattern with anti-slip design ensures secure bundling. These features make PP belts both economical and effective for light-duty applications.
Common Sizes: 1206, 1208, 1507, 1508, 1510 (customized available)
We offer standard specifications like 1206 to 1510 with customized options based on customer requirements.
Compatible Tools: Manual, Semi-Automatic, and Automatic Strapping Machines
Manual strapping machines are compatible with PP straps ranging from 12 to 16mm in width. For higher efficiency needs, our straps support semi-automatic and fully automatic balers as well.
Ideal Use Cases: Light Industrial Goods, Food Packaging, Textiles, Retail Packaging
PP straps are widely used across industries requiring lightweight yet secure packaging, such as department stores, food processing units, printing houses, pharmaceuticals, textiles, and logistics.
Features and Applications of PET Strapping Belts
Material: Polyester (PET)
PET strapping bands are high-strength alternatives to steel straps made from polyester resin.
Key Characteristics: Steel-Like Strength, 5% Tension Retention Rate, Weather Resistance, Recyclable
They maintain 5% tension without loosening and offer elongation under strong impacts to ensure cargo safety. Excellent weather resistance allows use between -50℃–100℃ while maintaining stability.
Cost Efficiency: One Ton = Length Equivalent to Six Tons of Steel Belt
One ton of PET strap equals the length of six tons of steel straps—reducing cost by up to 60% while improving handling safety.
Compatible Tools: Pneumatic and Electric Strapping Machines
Our PET belts are designed for pneumatic balers operating at 0.5–0.8MPa or electric balers offering tension speeds up to 200mm/s for precision control.
Ideal Use Cases: Heavy Loads like Ceramics, Metals, Machinery; Long-Distance Transport
PET straps are optimal for securing heavy-duty goods such as ceramics, metal components, and industrial equipment, especially during prolonged transit.

Five-Step Checklist for Choosing the Right Strapping Belt Solution
- Assess load weight & fragility.
- Determine transport distance & environmental exposure.
- Choose appropriate material – PP for light loads; PET for heavy-duty.
- Match belt size & thickness with equipment
- Opt for customized branding & accessories if needed.
FAQ
Q: What’s the difference between a PP strap and a PET strap?
A: PP is lighter with high flexibility suited for light goods; PET offers steel-like strength ideal for heavy-duty loads over long distances.
Q: Can I use manual tools with both types?
A: Yes. Manual tools work effectively with both PP & PET straps, ranging from widths of 12–19mm depending on application needs.
Q: Are your strapping solutions eco-friendly?
A: Absolutely. Our products meet EU environmental standards, ensuring no harmful substances are used—making them suitable even for export packaging.
Q: How do I choose between pneumatic and electric tools?
A: Pneumatic tools are ideal for fast-paced operations using compressed air; electric tools provide precise tension control—best when accuracy is critical.
Q: Do you offer customized logo printing on straps?
A: Yes. We provide fully customized solutions, including color matching and logo printing tailored to your branding requirements.
