Testing methods and standards
For more than 50 years now, Innventia have been engaged in testing of packaging and packaging materials.
 
The Materials testing laboratory has advanced equipment for the testing of fibre-based materials such as paper, cardboard and corrugated board as well as of plastics and various composite materials.
 
In the climate chambers both materials and packages are exposed to various temperatures and humidity conditions in order to establish whether for instance their strength properties are affected by different outer conditions. 
 
We test according to the following test methods and standards:
