PP Strap vs PET Strap: a comparison in packaging and transportation

PP Strap vs PET Strap: a comparison in packaging and transportation

In the dynamic world of packaging and transportation, the use of the right materials plays a crucial role. Two of the most commonly used materials are PP strap (polypropylene) and PET strap (polyethylene terephthalate). Although they may seem similar at first glance, they have different properties and applications. Let’s delve deeper into these two materials and their differences.

What is PP-strap? 

PP strap, made from polypropylene, is a lightweight and economical packaging material. It is primarily used for light to medium loads. PP strap is easy to use and recycle, and it offers good resistance to chemicals and moisture. However, it is less strong than PET strap and is more susceptible to UV damage and temperature changes.

Advantages of PP Strap

  1. Cost-effective: PP strap is generally cheaper than PET strap.
  2. Flexibility: It is flexible and easy to handle, making it ideal for manual applications.
  3. Recyclable: PP strap is fully recyclable, making it an environmentally friendly option.

Applications of PP Strap

  • Packaging of light to medium-weight boxes.
  • Bundling small items.
  • Use in warehouses and distribution centers. 

What is PET Strap? 

PET strap, made from polyethylene terephthalate, is stronger and more durable than PP strap. It is excellent for heavy loads and has high tensile strength. PET strap stretches less and maintains its tension longer, making it ideal for applications where long-term stability is required.

Advantages of PET Strap: 

  1. Strength and durability: PET strap is stronger and lasts longer.
  2. Resistance to UV radiation and weather conditions: It is more resistant to damage from sunlight and extreme temperatures.
  3. Suitable for heavy loads: Ideal for packaging and stabilizing heavy goods.

Applications of PET Strap

  • Packaging heavy items such as building materials and metals.
  • Stabilizing loads on pallets for transportation.
  • Applications in the export sector.

Comparison and Conclusion

Although both PP and PET straps have their place in the world of packaging and transportation, the choice depends on the specific needs of the load. For lighter, cost-effective applications, PP strap is an excellent choice. For heavier, long-term applications where stability is crucial, PET strap is the better option.

Understanding these differences can help in making an informed choice that maximizes the safety and efficiency of transportation and storage.

Polyester strap, an excellent alternative for steel strap

PET of staalband

Strapping properly depends on the type of strap chosen.

Certis Benelux offers different types, namely steel strap and polyester strap (PET). Many people opt for steel strap as the “safe” choice. However, we’d like to promote polyester strap since in many cases it is better and cheaper.

Find out why in this article.

Less impact on the environment

It takes a lot of energy to produce steel. Clearly that is disastrous for our planet and also very expensive. Polyester strap, on the other hand, consists largely of recycled material and it weighs five times less than steel strap. Naturally that has an enormous impact on transport. And finally, polyester strap is easy to recycle.

Safer

Polyester strap is five times lighter than steel strap. This makes it a lot easier for workers to use and improves the ergonomics. Furthermore, in contrast to steel strap, PET strap does not have sharp edges which drastically reduces the risk of accidents. When being released, steel strap can fly in all directions which is dangerous to anyone standing nearby. And last but not least, if anyone drives over steel strap that is lying on the ground, there is a risk of damaging the tyres. That’s not the case with polyester strap.

Cheaper

To cap it all, the use of polyester strap is a lot more economical than steel strap. Not only is the product itself a lot cheaper, but you also save a lot of time. After all, polyester strap is a lot easier to attach. And the larger number of metres per roll means you don’t have to change rolls as often.

Higher quality

Economical is one thing, but what about the quality? You can rest assured that polyester strap has at least the same quality as steel strap. Take the elasticity for example. Where steel strap strands at 0.1 %, PET offers an elasticity of up to 14 %. In concrete terms, this means that PET strap can absorb more shocks without breaking. Even if the load shifts, shrinks or expands. That’s precisely why you should opt for polyester strap for loads that shrink when they cool down or dry out. And PET strap is weatherproof. Whilst steel rusts, PET strap will not create stains.

This is how Certis works to be more eco-friendly

The climate affects us all. Companies too. And we realise that all too well at Certis Benelux, so we make an effort to keep our carbon footprint to a minimum.

It all starts with our products. We do everything possible to make both our machines and our consumables as economical and efficient as possible. That not only benefits the environment, but also our clients’ production process and their bottom line. A concrete example is Nano wrapping film. Environmentally friendly, thanks to the fact it is made up of 30% recycled materials, but still as reliable as ‘classic’ film. In addition there is the Wrappah turntable wrapper, which creates less packaging waste.

We can’t win the fight against climate change on our own! That’s why we require our suppliers to meet high standards. Naturally not just with regard to quality; their carbon footprint must also be as small as possible.

Finally, we also take our responsibility seriously internally. For example, we are digitising processes to keep paper consumption to a minimum. What’s more, we increasingly hold our meetings via video to avoid travelling.
