When it comes to plastic strapping solutions, two of the most common options are PP (polypropylene) strapping and PET (polyester) strapping. At first glance, they may look similar, but they perform very differently. Each material offers unique benefits depending on your packaging load, storage conditions, and budget.
This guide compares PP vs PET strapping in terms of material properties, strength, elasticity, weather resistance, and cost — so you can choose the right solution for your packaging needs.
1.PP vs PET Strapping Material Properties
PP (Polypropylene) Strapping :
- Lightweight, flexible, and easy to handle
- Perfect for carton strapping and general-purpose packaging
- Suitable for operations requiring speed and convenience rather than heavy tension
PET (Polyester) Strapping :
- Strong, stiff, and highly durable
- Often used as a steel strapping alternative due to its superior tensile strength
- Maintains shape even under high pressure, ideal for industrial applications

2.PP vs PET Strapping Strength and Load Capacity
PP strap is best for lighter loads such as parcels, food boxes, or retail packages. It provides sufficient tension for light-duty bundling and ensures cost efficiency for high-volume use.
PET strap, on the other hand, is built for strength. Its high tensile capacity allows it to secure heavy-duty pallets and products such as bricks, timber, or steel. PET straps also maintain consistent tension, preventing load shift during transport.

3. Elasticity and Tension Retention of PP and PET Straps
PP Strap:
- More elastic, allowing it to absorb shock and minor movement
- However, it can lose tension over time, making it less suitable for long-term storage or long-distance shipping
PET Strap:
- Offers superior tension retention and minimal elongation
- Excellent for export shipments or goods stored for extended periods

4. Environmental Resistance: PP vs PET Strapping Band
Environmental conditions can greatly affect strapping performance.
- PP Strapping band may degrade under UV exposure and high temperature, making it best for indoor or short-term use.
- PET Strapping band provides high resistance to UV light, heat, and cold, which makes it ideal for outdoor storage and international shipping.
5. Polypropylene(PP) and Polyester(PET) Strapping Cost Comparison
Cost often plays a key role in packaging decisions.
- Polypropylene Strapping is budget-friendly, perfect for companies packaging lightweight goods in large quantities.
- Polyester Strapping has a higher upfront cost, but it requires less re-strapping and fewer replacements, offering better long-term value for heavy or industrial loads.
6. Applications of Polypropylene and Polyester Strap
Polypropylene Strap Applications:
- Box strapping
- Light pallets and carton bundling
- Food and beverage packaging
- Consumer goods distribution
Polyester Strap Applications:
- Industrial pallets
- Construction materials (timber, bricks)
- Metal and steel coils
- Long-distance and export shipments

8. Which Strapping to Choose for Your Industry
- E-commerce & Logistics: Choose PP strapping for lightweight parcels and high-volume packaging lines.
- Construction & Manufacturing: Use PET strapping for heavy pallets and sharp-edged products.
- Food & Beverage: PP strapping ensures clean, smooth, and economical sealing.
- Export Shipping: PET strapping offers better tension retention and withstands temperature variations.
9. Sustainability and Recycling
Both PP and PET band are recyclable, but PET has a higher recycling value and can be manufactured from recycled plastic flakes. This makes PET an eco-friendly option for businesses adopting sustainable packaging practices.
10. Safety and Handling Tips
To ensure safety and efficiency when using strapping tools:
- Match the strap width and thickness to your product weight.
- Avoid over-tensioning to prevent strap snapping.
- Always wear gloves and safety glasses when applying or cutting straps.
Conclusion
- Choose PP strapping if you need a low-cost, flexible solution for light loads.
- Choose PET strapping if you need a high-strength, durable, and weather-resistant option for heavy-duty applications.
Both PP and PET strapping play essential roles in modern packaging. The right choice depends on your load weight, storage conditions, and transportation distance.
