Weathering test - wet smear resistance of printed peat culture, substrate and humus packaging
Testing the resistance of printing inks to environmental influences such as moisture, sunlight (UV radiation) and to substances eluted from the filling materials (e.g. humic acids, agricultural chemicals) during outdoor weathering. For the practical assessment of the wet smear resistance of the printing and the weather resistance of the film materials in the time-lapse test, including the pallet securing film, by means of artificial weathering with xenon arc light in accordance with DIN EN ISO 4892-2.
In short — AI-generated
This test evaluates the durability of printing inks and film materials used for peat and humus packaging when exposed to environmental stressors. Samples are subjected to artificial weathering using xenon arc lamps in accordance with DIN EN ISO 4892-2 to simulate the combined effects of UV radiation, moisture, and chemical exposure from the filling material.
The results indicate how well the print remains smear-resistant and how stable the packaging film remains under outdoor conditions. This data helps developers ensure that branding and product information remain legible and that the packaging maintains its integrity throughout the supply chain and storage period.
