When it comes to securing your products for shipping, two popular options often come up: PP (Polypropylene) strapping and PET (Polyester) strapping. But which one is actually better for your packaging needs?
If you’ve been scratching your head over this, you’re not alone. Many U.S. businesses—from e-commerce sellers to manufacturing plants—ask the same question before making a bulk purchase.
Let’s break it down in simple terms, so you can make the smartest (and most cost-effective) decision.

It’s usually found in:
-
Heavy-duty palletizing
-
Construction materials bundling
-
Beverage industry packaging
-
Long-term outdoor storage
Key benefits:
-
High breaking strength

Which One Should You Choose?
Here’s the truth—it ain’t about which one is “better” in general, but which one fits your specific needs.
-
If you’re shipping lightweight to medium-weight goods and want lower costs → PP strapping is your friend.
-
If you’re handling heavy loads or outdoor storage → PET strapping is the safer bet.
Why PP Strapping is the Go-To for E-commerce
For e-commerce sellers in the U.S., PP strapping is the clear winner because:
-
Lower cost per meter = Higher profit margins
-
Works perfectly with small to medium cartons
-
Easy to customize with colors and printed logos
-
No sharp edges = Safer for handling
-
More meters per roll means fewer machine changeovers

Mistakes to Avoid
One common mistake? Buying PET straps when PP would do the job just fine.
It’s like using a sledgehammer to crack a nut—overkill and unnecessarily expensive.
Another mistake is ignoring machine compatibility. Always match the strap’s width, thickness, and coil size to your strapping machine.
