When it comes to plastic strapping solutions, two of the most common types are PP strapping (polypropylene banding) and PET strapping (polyester strapping). While they may look similar, they differ in material properties, strength, durability, and cost-effectiveness. Understanding the differences will help you choose the right strapping tape for your packaging needs.
1. Material Properties
- PP Strapping (Polypropylene banding): Lightweight and flexible. Ideal for carton strapping or general-purpose packaging that doesn’t require extreme strength.
- PET Strapping (Polyester banding): Tougher and more durable. Often considered the best steel strapping alternative due to its high resistance to breaking under heavy strain.

2. Strength and Load Capacity
- PP: Best for lighter loads such as small parcels, food boxes, or retail packaging.
- PET: With high tensile strength, PET is designed for heavy-duty pallet strapping, securing items like bricks, timber, or metal.

3. Elasticity and Tension Retention
- PP: More elastic, but tends to lose tension over time. Suitable for packages that aren’t stored long term.
- PET: Excellent tension retention and stability, making it a reliable choice for long-distance shipping or storage.

4. Environmental Resistance
- PP: Can degrade under UV exposure and extreme weather. Best for indoor storage or short-term use.
- PET: Highly resistant to UV, heat, and cold. Works well for outdoor packaging applications.
5. Cost Considerations
- PP: Budget-friendly and cost-effective for high-volume strapping where heavy strength isn’t needed.
- PET: Higher upfront cost, but reduced need for re-strapping makes it more economical for heavy loads in the long run.
6. Application Types
- PP Strapping uses: Box strapping, light pallets, food packaging, consumer goods.
- PET Strapping uses: Industrial loads, construction materials, steel coils, export shipments.

Conclusion
- Choose PP strap if you need a low-cost, flexible solution for light loads.
- Choose PET strap if you need a high-strength, durable, weather-resistant option for heavy-duty applications.
Both play an important role in the packaging materials industry, and selecting the right one ensures efficiency, safety, and cost savings.
