Choosing the Best Strapping Material

Ok, let’s start things off by clearing this up: this title is a bit of a misnomer. There’s no such thing as “The Best Strapping Material”. However, add some context like “…for heavy-duty industrial part shipments,” now we’re on the right track.

So, rather than spend time explaining why packing straps are crucial for shipping heavy loads and how the right strapping choice can be the difference between a flawless delivery and costly damage, let’s get right into understanding the three most common types of strapping materials.

The Big Three

Here at Whitebird, you’ll find the three main types of strapping: Polypropylene, Polyester, and Steel. While they may all technically serve the same purpose, what you’re strapping down plays a big role in choosing the right material. There’s no one-size-fits-all solution. Let’s break down each of these options so you’ll know which type of packing straps you’ll need.

Polypropylene (PP) Strapping

Economical and widely available, Polypropylene Strapping is a trusted and cost-effective solution for securing palletized products, cartons, and bundled materials. While particularly well-suited for lightweight to medium duty applications, it is also commonly used for larger shipments that do not require high tension retention. Polypropylene strapping holds well under typical conditions during transport, although it’s important to note that it is not recommended for extended outdoor use due to its low UV resistance. Ideal for everyday packing needs, polypropylene strapping is a user-friendly, lightweight and flexible option. However, if you are looking for a solution to better handle medium to heavier-duty applications, you may want to consider upgrading to Polyester Strapping.

Polyester (PET) Strapping

When it comes to strapping options, Polyester Strapping fits comfortably in the middle. It offers a mix of benefits from both polypropylene and steel strapping. It can offer tensile strength that’s comparable to steel but with superior elongation and recovery, meaning it’ll help absorb shocks during shipping without breaking. It’s also weather-resistant, UV-stable for outside storage and safer to handle as it has no sharp edges. If you’re working with shipments that don’t call for the top-tier strength of steel strapping, PET is an excellent, cost-effective option for securing your products.

Steel Strapping

When you’re dealing with heavy-duty shipments, it’s time to bring out the big guns. Steel Strapping is the tried-and-true option for demanding loads like heavy machinery, building materials, steel coils, etc. It offers maximum strength and durability, heat resistance, and reliability, perfect for industrial manufacturing and high temperature environments. However, this strapping material requires specialized tools and proper training, and the superior strength comes at a higher cost.

How to Choose the Best Strapping Material

While each type of strapping has its uses, it’s all about choosing the right tool for the job. When you’re deciding what type of strapping you’ll need, there are three key factors to consider: load weight, product type, and shipping conditions. In addition to these factors, it’s important to consider your budget, equipment requirements, and the environment in which the shipments will be stored.

As a general rule, you’ll want to use Polypropylene Strapping for light-medium, low-risk shipments. Polyester Strapping for moderate to heavy loads that need some added shock absorption. Steel Strapping for extremely heavy, dense or sharp-edged loads. See the strapping material comparison table below for a quick reference to help decide which option best fits your needs.

Strapping Material Comparison Table

Strapping Type	Best For	Strength	Cost	Keep in Mind
Polypropylene (PP) Strapping	Light to medium applications	Low tensile strength	Low: least expensive option	UV-sensitive; not ideal for outdoor storage
Polyester (PET) Strapping	Medium to heavy applications	High tensile strength with superior elongation	Medium: more affordable than steel	Absorbs impacts without breaking
Steel Strapping	Heavy or highly demanding applications	Highest strength, minimal elongation	High: premium cost	Requires specialized tools/training
