There has been much talk in the industry about Nanotechnology over recent months. But what exactly is it? And how can it benefit your packaging solutions?
Nanotechnology is quite literally technology that is conducted at Nanoscale – in essence, the ability to see and control what individual atoms and molecules do and then use them more effectively. Over recent years, new technology had been developed which allows us to understand how microscopic atoms and molecules, invisible to the naked eye, work together. This new understanding has in turn given us the ability to increase and improve the performance of many different products.
Nanotechnology is used all around us – in polymer composites, for surface treatment of fabrics to resist staining or bacterial growth, to develop thin films for eye glasses, for computer or camera displays and in windows to name but a few.
All very sophisticated and clever stuff.
The use of nanotechnology specifically within packaging is an exciting breakthrough and one that we at MorsaWrap are fully embracing.
Pallet-Wrap has traditionally been made using five layers of polymer, which make up the film and give it its characteristics. So, a 5 layer pallet wrap film in its “crude” form will have a core layer that provides the performance of the film, its stretchability, puncture resistance and clarity etc. The two outside layers slip on one side of the roll to stop two pallets sticking together and the other is cling which means the film sticks to itself. The inside layer will be cling that ensures that the film sticks to itself and doesn’t fall off the pallet while the inside two layers are barrier layers to prevent the cling from migrating through the film.
As the packaging world has begun to embrace nanotechnology, we are now working with films that have 20 to 35 layers which allows us to have more control of the molecules and to increase the effectiveness of their performance.
This can deliver significant benefits in stretchability, puncture resistance and, crucially, increase the holding force. As a consequence, we’re able to get thinner films to perform in the same manner as thicker traditional films.
Nano Technology allows us to deliver higher performance products and all manner of benefits including:
This improved holding force allows customers to benefit from a reduction in packaging weight and increase their production throughput as a result of faster packaging speeds.
The packaging world is beginning to wake up to the benefits in performance that nanotechnology provides and the higher performance products it allows to be created.
