Question 1

What is PET strapping?

Accepted Answer

PET strapping is a high-strength strap made from polyester resin, used to unitize, bundle, and secure industrial loads. It combines high retained tension with elongation and recovery, so it keeps holding as loads settle or bales expand.

Question 2

What is the difference between PET and polypropylene strapping?

Accepted Answer

Polypropylene is a lighter-duty strap suited to light bundling and box closing. PET carries substantially higher break strength, retains tension far better over time, and is the appropriate choice for heavy industrial unitizing and load securement.

Question 3

Can PET replace steel strapping?

Accepted Answer

In many applications, yes — where the application requirements are met. PET does not rust or stain product, is lighter and safer for crews to handle, and holds tension as loads settle. Steel remains appropriate for some hot, sharp-edged, or extreme-load applications, so the right answer depends on the specific application.

Question 4

What PET strap width do I need?

Accepted Answer

Width is driven by load weight, edge conditions, and the tool or machine applying the strap. 1/2" suits light- to medium-duty work, 5/8" is the general-purpose industrial width, and 3/4" is used for heavy-duty unitized loads. Send us your current strap details and application and we will confirm.

Question 5

What is break strength? What does retained tension mean?

Accepted Answer

Break strength is the load at which the strap fails in a straight pull. Retained tension is how much of the applied tension the strap still holds hours or days after application. A load can be secure at the moment of strapping and loose on arrival if the strap does not retain tension — which is why both figures matter.

Question 6

Can PET strap run through automatic equipment?

Accepted Answer

Yes. Machine grade PET is produced for automatic and semi-automatic equipment, where consistent thickness, camber control, and joint performance determine whether the machine feeds and seals reliably. Tell us your machine make and model and we will match the strap to it.

Question 7

Can Heavy Strap provide samples?

Accepted Answer

Yes. The only meaningful way to evaluate strapping is in the application where it will actually run. Request a sample and we will send strap matched to your current specification for testing on your own equipment.

Question 8

Do you offer volume pricing?

Accepted Answer

Yes. Pricing reflects application and volume, including coils per month, order quantities, and annual usage. Share those details on the quote request and we will build a program around them.

Question 9

What information do you need to cross-reference my existing strap?

Accepted Answer

Width, thickness, break strength, coil length, core size, current manufacturer, and product number if you have it — plus the tool or machine applying the strap. A photo of your current coil label usually captures most of this, and you can upload one on the Match My Current Strap page.
