The powered prestretch advantage

The powered prestretch advantage

 

Have you heard about Powered Pre-Stretch (PPS) in pallet wrapping? This advanced technique is revolutionizing the way loads are secured for transportation. Let's dive into the details of how PPS can improve load stability, reduce material usage, and save costs.

Enhanced Load Stability

Powered Pre-Stretch (PPS) involves mechanically stretching the film before it is applied to a load. This pre-stretching process ensures that the film conforms tightly to the contours of the load, creating a secure wrap. As a result, the load is less likely to shift or become unstable during transit, reducing the risk of damage or loss.

Watch below as the Mytho S PRS (Power roller stretch) prestretch system wraps these goods. 

Motorized Rollers: The film passes through rollers that rotate at varying speeds, effectively stretching it.

Pre-Stretch Ratios: Depending on the machine, the film can be stretched from 150% up to 400% of its original length. For instance, the Synthesi/Synthesx OPS Pre-Stretch Pallet Wrapping Machine offers pre-stretch levels of +150%, +200%, or +250%

Consistent Tension: The pre-stretched film is applied to the load with uniform tension, ensuring optimal coverage and stability. 

Reduced Material Usage

One of the key benefits of Powered Pre-Stretch (PPS) is its ability to stretch the film to its maximum potential, using less material to wrap each load. By stretching the film mechanically, the same amount of film can cover a larger surface area, reducing the overall amount of film needed for each pallet. This not only saves on material costs but also contributes to a more sustainable packaging process.


Cost Savings

Implementing Powered Pre-Stretch (PPS) in pallet wrapping can lead to significant cost savings for businesses. By reducing material usage and improving load stability, companies can lower their packaging expenses and minimize product damage during transportation. In fact, studies have shown that PPS can result in cost savings of up to 30% compared to traditional wrapping methods.

So, if you're looking to enhance the efficiency of your pallet wrapping process, consider incorporating Powered Pre-Stretch (PPS) technology. Not only will it improve load stability and reduce material usage, but it will also help you save costs in the long run. Stay ahead of the curve with this advanced pallet wrapping technique!

Powered Pre-Stretch (PPS) is an advanced technique in pallet wrapping that involves mechanically stretching the film before it's applied to a load. This method enhances load stability, reduces material usage, and offers significant cost savings.

See our example from a not so recent test. 

Example of Prestretch film savings


We’ve done a test not so recently for a higher volume user.

These are 2 pallet wraps priced relatively the same per kg, Hand is typically always more as its more labour intensive to make. so we have use the relatively higher KG rate for hand. 

Code Description Roll Price KG price
HAC20A 500MM X 20UM X 3.7KG NETT CLEAR CAST HAND STRETCHWRAP-AUS $14.17 $3.82
HAE20 500MM X 20UM X 14KG NETT CLEAR CAST MACH. WRAP – IMPORTED 300% YIELD. $49.90 $3.56

We tested on 2 machines and by hand.

All wrapped:

Wrapped 3 times at the bottom, 3 times at the top, wrapped up and down.

Machine Settings:
The Electromagnetic brake pallet wrapping machine Set to 65% Film Braking.
3 bottom wraps, 3 top wraps.
An electromagnetic machine is basically a slightly more advanced machine than a friction brake machine, it will use the  same amount of film as a friction brake machine. 

PPS Machine Settings:
Equipped with 220% PPS ratio (3.2x)
3 Bottom wraps, 3 top wraps.

We cut the film off each pallet and weighed them.

Now mind you by hand I wrapped this pretty well and put a lot of effort in, a typically  hand user going about their job day to day might not always be stretching wrap this much.

 

The results:

Type Stretchwrap used 1 pallet 100 pallets 1000 pallets 10,000 Pallets
Hand 443g $1.69 $169.00 $1,690.00 $16,900.00
Electromagnetic 434g $1.54 $154.00 $1,540.00 $15,400.00
PPS 175g $0.62 $62.00 $620.00 $6,200.00


You can see here there are significant savings to be had in terms of stretchwrap used and the price.

PPS Machines in the Australian Market

For businesses in Australia seeking to adopt PPS technology, MPS offers a range of pallet wrapping machines equipped with powered pre-stretch capabilities. The Mytho S – Powered Prestrech Machine, for example, is an Italian-made machine capable of stretching 1 meter of wrap to 3.5 meters, providing users with significant savings on wrapping costs

Conclusion

Implementing Powered Pre-Stretch technology in pallet wrapping operations offers numerous advantages, including cost savings, improved load stability, and environmental benefits. For businesses handling high volumes or lightweight products, investing in a PPS machine can lead to more efficient and sustainable packaging solutions.
