Proof of plastic

Detection of plastics in cardboard/paper samples by means of microtome cross-section and IR screening. If necessary, other methods are used to determine the plastic content. The cleaning of filled samples is charged additionally.

Test Method Group: Material analysis

Norms:

In-house method PV061 (2019-09) Infrared spectroscopy
DIN 51451 (2020-02) Testing of petroleum products and related products – Analysis by infrared spectrometry – General working principles

Required Sample Amount: Depending on task, e. g. at least approx. 50 x 50 mm material or at least two pieces of the product

Standard Tests

Examination of paper or board materials for plastic components according SUPD

Specific Norm: Hausverfahren PV061

The material is examined for the presence of plastic layers (according SUPD) with a thickness of >1 µm and particles with > 10 µm diameter. Partially applied layers, especially those with a thickness of <1 µm , incorporated plastics (e.g. impregnations of the pulp fibers), contained particles with a diameter <10 µm as well as the binders of applied coatings cannot always be reliably detected with this analysis package.
