Material analysis

The quality of your packaging is it always the same?
Does your new packaging has the right quality?
In discussion with your supplier or with a customer?
We can determine the technical properties for paper, folding carton and corrugated board as well as for plastic materials, .

  • UV test

    UV testing on laboratory level – as in ASTM G53 – allows us to perform short term qualitative controls on materials instead of exposing the material during 5 to 10 years at the sunlight.
    The equipment has to comply with ASTM G53/96 and equipped with fluorescent UV-B lamps.

    The test samples are exposed in alternation to UV light and condensation in a repetitive cycle of 200 hours.
    The test cycle includes 8 hours UV radiation at a temperature of 60° C followed by 4 hours condensation at 50°C.

    After 200 hours exposure, the breaking strength and extension are determinated in accordance with ISO 13934-1.
    The obtained values are compared with the test samples conditioned in the dark on cool temperature.
    All load bearing materials of the FIBC must – after testing – maintain 50% of their original breaking strength and extension.
