Packaging testing

UKAS-accredited in-house test facilities

We pride ourselves on being able to test our packaging to the highest standards. Our in-house test facilities are UKAS accredited, ensuring packaging is fit for road, sea and air.


We’re one of only six UKAS-accredited dangerous goods packaging testing facilities in the UK.

And one of just two packaging companies to be able to offer UKAS-accredited dangerous goods testing for corrugated boxes, on site.




Quality assurance

We’re constantly measuring the quality of our materials and products against the market and industry standards to ensure we consistently outperform all other like-for-like products.


Bespoke testing

Talk to us about your requirements and we can work with you to build the right tests for your needs. Our lab is equipped to replicate the extreme conditions packs may be subjected to throughout transit, and our team of experts are on-hand to help with any specialist requests.




Dangerous goods testing

We produce and test dangerous goods packaging that meets the UN’s certification standards, giving you true peace of mind.

We replicate the conditions your packaging may be exposed to – testing for strength, hot and cold temperatures, moisture, high humidity, even blast and corrosion resistance.

“Having worked with Tri-Wall for a number of years now, they are great to work with and always reliable”

John Richardson
Barbour & Sons

“Tri-Wall does all of our VCA certification and HSE negotiation. Such a strong relationship with HSE means we’re able to push through packaging for international, which is really vital to our business.”

Tri-Wall customer

“We have a unique set-up. We have a huge amount of material stored at a 3rd party warehouse. With very little space on site, we rely on Tri-Wall for daily deliveries, with up to 4 deliveries per day. If we had an unreliable supplier and they missed one day, it could shut down the entire plant.”
