Hey there! If you're a packaging buyer, engineer, or procurement specialist, you know this truth: choosing the right strap isn’t just about cost per roll. It’s about durability, safety, regulatory compliance, and peace of mind. At Juhong Packing Materials, with over 25 years of experience in producing PET, PP, and steel straps — plus steel seals, films, tools — we’ve seen what happens when someone uses a “cheap strap” instead of a high-performance one, especially in rail, intermodal, or long-haul transport.
In this article, we’ll dive deep into AAR Approved PET Strapping versus more “ordinary” straps (non-certified PET, PP). We’ll compare strength, tension retention, environmental resistance, safety, cost over time, and more. If you care about pet vs pp plastic, polyester strapping manufacturers, or you want to understand what “AAR approved PET strapping” really gives you — this article is for you.
Before comparing, let’s define what we mean by “ordinary plastic straps.”
PP (polypropylene) strapping is widely used for light to medium duty packaging.
It is a type of plastic that is derived from the monomer propylene. PP is known for its versatility, durability, and chemical resistance, making it suitable for a variety of uses across industries. Some common applications of PP include packaging (such as containers and bottles), automotive parts, textiles, medical devices, and household goods. PP can be recycled and is valued for its balance of properties like stiffness, toughness, and resistance to heat and chemicals.
It’s relatively inexpensive, easy to handle, quite elastic, works well for bundling cardboard boxes, pallets of lighter goods, short-distance transport, indoor storage. But it has limitations: it loses tension over time, especially in heat or humidity, weaker in impact resistance, less durable if exposed to UV or outdoor environments.
This refers to polyester straps made without standardized testing or approvals like AAR (or where performance is lower than required). These might be cheaper, but performance can vary widely. Tensile strength, retained tension, material finish (smooth vs embossed), quality of resin, and consistency are all risk points.
What makes AAR-certified PET strapping “premium”? Why do many shippers and industrial users insist on it?
AAR = Association of American Railroads. Here’s what certified means:
The strap meets mechanical tests for break strength, elongation, tension retention.
Environmental testing (UV, moisture, etc.) so it survives real use.
Manufacturer audited for consistent quality.
Listed in official AAR tables so buyers can verify.
Compared to ordinary PET or PP, AAR PET straps are:
More consistent from batch to batch.
Better tension retention (they stay tight even after vibration, transit, environmental changes).
Better finishes (waxed, embossed, smooth, etc.) to reduce slippage or abrasion.
Better safety and handling features.
To fairly compare AAR PET vs ordinary straps, here are the criteria you care about (and which Juhong tracks carefully):
How much load can the strap hold before it breaks. A critical spec in heavy load, steel coil, timber, etc. Ordinary PP might have lower break strength; non-certified PET can vary. AAR PET straps are tested to meet or exceed required break loads.

How much the strap stretches when tensioned and how well it recovers (resistance to permanent deformation). Ordinary straps, especially PP, tend to stretch more and stay stretched — loosening load over time. AAR PET has better “elastic memory.”
After installation, how well does the strap keep its tension over time, under vibration, temperature/humidity fluctuation, handling. One of the biggest differences: AAR Approved PET Strapping retains tension much longer. PP loses tension quicker.
UV exposure, moisture, temperature extremes, chemicals, abrasion. Ordinary straps might degrade or weaken. AAR PET is designed for durability in these conditions.
We consider not just price per meter, but:
Damage claims from failed straps
Labor for re-strap or adjusting slack
Handling injuries or tool wear
Cost of replacement
Transportation cost (weight)
Now, let me show you how Juhong Packing Materials leverages all these criteria — how our AAR PET strapping compares (and often outperforms) many “ordinary straps.”
Juhong Packing Materials, founded in 1997, operates a 20,000 m² factory in China. We produce 12,000 tons of PET straps , 60,000 tons of steel straps, 300 million steel seals, 12,000 tons of stretch film. This scale lets us keep costs competitive and consistency high.
Our Polyester straps are AAR-approved,AAR 124, meet EN,ASTM and GB standards, and we maintain ISO9001, ISO14001, ISO45001 quality and environmental system management.
Qualtity Management: Internal self-inspection, pre-production raw material testing,in-process inspection, tensile / break load testing,final product sampling inspection,Issuance of self-inspection reports and third-party testing such as SGS testing conducted according to customer requirements
We offer Poly straps in widths from 9mm up to 32mm; thicknesses from 0.38mm upward, with finishes (smooth, embossed )
Clients can choose break strengths, core sizes, roll lengths.

While the up-front cost of AAR-certified PET straps is higher than the cheapest PP straps, our clients see lifecycle cost savings:
Fewer shipments rejected or damaged
Less re-strapping or tensioning labor
Lower replacement and disposal cost
Reduced injury risk and related insurance / liability costs
Lower shipping cost per unit due to lower strap weight
Here’s a summary table comparing Juhong’s AAR PET (high-performance straps) vs two kinds of “ordinary straps”: Non-certified PP, Non-certified PET, and basic steel straps (non-AAR)
To help illustrate, here are scenarios where Juhong’s AAR PET straps outshine ordinary straps
A steel coil manufacturer ships heavy coils from a mill, then loaded onto flatcars, then transferred to intermodal containers. With ordinary steel straps, some coils shifted in transit, rusting stain on shipments, and high replacement cost. Switching to Juhong’s AAR PET strap (with comparable break load, proper finish) reduced damage claims by ~30%, reduced rework time, and lowered weight-based freight cost because straps are lighter.
A timber yard bundles planks for cross-country shipments. Planks exposed to humidity and rain. Ordinary PP straps stretched and slackened, bundles moved. With Juhong’s AAR PET straps (embossed finish, proper tensioning), the bundles stayed intact; loading/unloading easier.
If you’re going to buy, here are what to look for (and what Juhong provides):
Must show AAR certification (or table reference)
Manufacturer name
Width, thickness, break strength clearly marked
Embossed / Smooth finish reduces slippage and abrasion
Longer roll lengths reduce changeovers
Proper core size for tools / machines
Packaging that protects strap during shipping
Compatible tools (manual, pneumatic, power tools)
Seals or buckles that match finish and strap type
Sample requests to test in your environment
Specification sheets (PDFs) and test reports
Technical support / consultation
Often, buyers focus on upfront cost and miss the bigger picture.
Ordinary PP Strapping is cheapest per meter.
Non-certified PET Strapping is somewhere between PP and certified PET Strapping.
AAR-certified PET Strapping (from a high-quality manufacturer like Juhong) is higher cost per meter, but…
More frequent failures → re-strap / replacement
Labor cost for adjusting slack / re-securing loads
Product damage / claims / rejections
Material waste / environmental disposal when straps break or degrade
When you factor all that in, many customers find AAR PET (though higher upfront) ends up cheaper over lifetime. Juhong works with many buyers who’ve done side-by-side tests over multiple shipments and found lifecycle savings of 20-40% compared to steel strapping or cheaper PP strapping, depending on volume, handling, environment.
Here are common questions
PP may be cheaper, but if you need tension retention, resilience, and durability (especially for heavy loads, intermodal or intermodal + rail transport), PP often doesn’t map up. PET under AAR standards gives stronger, more durable grip and fewer issues.
Steel strap has its strengths, static tensile strength for securing the heaviest, sharpest-edged, but steel strap has many trade-offs: rust, weight, safety hazards, cost in handling and labor, more damage in case straps fail or cut edges damage cargo. PET strap can match steel in many applications when specified correctly and certified.So it cannot be said that any particular type of strapping is the best. Which binding to use depends on your specific needs and requirements, and the choice should be made based on the most suitable option for you.
To wrap it up:
AAR-certified PET strapping gives you consistent strength, better tension retention, superior environmental resistance, safer handling, and often lower total cost over time versus ordinary straps (non-certified PET, PP, or even basic steel).
