Aquapak partners with Industrial Physics to help customers transition to sustainable packaging


Aquapak Polymers has partnered with Industrial Physics to create a harmonised set of WVTR (water vapour transmission rate) testing methods for its Hydropol biodegradable polymer.

Hydropol offers all the benefits of traditional polymer plastics yet is water soluble and completely biodegradable as well as non toxic and UV resistant. It also offers multiple end of life options such as recyclability, compostability and compatibility with anaerobic digestion plants.

Establishing a reliable and repeatable test method for WVTR is an industry wide challenge. By using equipment designed by Industrial Physics’ product lines, including Systech Illinois, and Testing Machines Inc, Aquapak resolved to find a way forward by partnering with Industrial Physics, which will ultimately provide its customers across a wide range of sectors with a real alternative to using traditional polymers, helping them cut plastic pollution in the process.


Industrial Physics is a global test and inspection partner that works across a wide range of industry sectors to help customers protect the integrity of their packaging, products, and materials. The business is passionate about helping customers move to new, more sustainable packaging materials. The group is made up of numerous specialist testing brands including Systech Illinois, TQC Sheen, Quality By Vision, Eagle Vision, Steinfurth, Technidyne, RayRan, Testing Machines Inc, and many more.

As more organisations continue to strive for sustainable alternatives, it is unsurprising that demand for Aquapak’s Hydropol continues to grow – this is supported by Industrial Physics’ research that surveyed 255 packaging professionals around the world, highlighting that testing of new sustainable materials was a major challenge they face.

Almost half of the 255 global packaging professionals (49%) surveyed said meeting testing standards was one the biggest challenges they faced in wider adoption of sustainable packaging materials.

An example of this is that current WVTR test methods and standards are based around traditional polymers rather than sustainable, biodegradable alternatives such as Hydropol.

In order to continue its drive towards sustainable innovation in a way that didn’t sacrifice the integrity of the product, Aquapak approached Industrial Physics to support it in developing a repeatable and reliable test method for WVTR (water vapour transmission rate) for its Hydropol biodegradable polymer.

The WVTR test method is a known challenge for hydrophilic polymers, and the team at Aquapak was looking to utilise knowledge and resources from Industrial Physics to develop a testing method that could be carried out in-house as well as replicated at its customers premises wherever they were in the world.

Max Phippard, quality control manager at Aquapak, said: ‘Allowing the WVTR test to reach equilibrium means that we are confident in the results. Over the last few months, we have carried out full analysis of multilayer samples to gain an understanding of how our customers can replicate their own WVTR testing regime on Hydropol.’

He continued, ‘Being able to build a relationship with Industrial Physics and leverage its expertise in packaging barriers was critical to the success of this programme.’

Alan Shema, product line director at Industrial Physics, said: ‘We have reached a point where the WVTR test on Hydropol can be replicated anywhere in the world by using the approach taken by Aquapak and ourselves. This is a major step forward because it will shape how hydrophilic films are tested in future. It allows our global customers who source sustainable packaging materials such as Hydropol to carry out their own WVTR knowing they can trust the results.’
