PET vs PP: Which Strap to Use?
July 17, 2025
Producer of both Polypropylene (PP) and Polyester (PET) strap, Signode understands the fundamentals of plastic strap.
Polypropylene (PP) Strap
Manufactured from polypropylene with high elongation for stretch and recovery. We provide both embossed and flat strap available in multiple colors. Strap is suitable for light to medium loads.
Dylastic® Polypropylene Strapping Range which includes our Pro, Bio and PCR pp strap.
Polyester (PET) Strap
Manufactured from polyethylene terephthalate, it is a high-strength strapping solution. With low stretch to maintain tension over time, it is a high tensile strength comparable to steel strap for heavier duty applications.
Choosing the Correct Strap?
When to use PP Strap
- Strapping light to medium loads of cartons, bundles and pallets
- Suited for unitized products which do not expand and shift during transportation
- When working in indoor, temperature controlled environments
- Ideal with high stretch elongation for compressible loads
When to use PET Strap
- Strapping heavy or rigid loads such as bricks, timber, metals or larger palletized loads
- For loads which will be stored outside or in harsh conditions as PET resists UV, moisture and large temperature fluctuations
- PET is ideal for long distance shipping to hold tension over time
- Use PET to replace steel strap in certain applications
- Use when low elongation and high recovery is required for loads to stay tightly bound.
