The printing, handling and barrier characteristics of paper and packaging
Our new range of packaging permeability measurement equipment equipment is fast and reliable– producing results that are accurate in the parts per million range, (parts per billion with some gases). Measurements can take from as little as 30 minutes for some packaging samples.
A wide range of variations and sensors are available, depending on the specific application. Multi-chamber systems allow measurements to be produced on several samples at a time and different designs and clamping systems cater for various sample types.
We also offer a laboratory
testing service for companies who test too few samples to make the purchase
of equipment viable. Where required by legislation our testing service also includes gravimetric testing of sachets, pouches and other products/materials.
Why is permeability crucial for packaging?
The printability, mechanical handling and barrier properties of paper and packaging are determined largely by their permeability. Relatively small changes to the makeup of a coating can result in disproportionately large changes.
With most packages the principal concern is water vapour permeability but in the case of some perishable and other goods it is critically important to measure the permeability of, oxygen, nitrogen, CO2, hydrocarbons and some other gases or vapours.
