Whether evaluating raw polymer batches, inspecting incoming raw materials, or comparing structural plastics, the ISO 178 three-point bend test provides a simple, standardized method to characterize material stiffness and strength under bending loads. The Labthink C610M Auto Tensile Tester is built for this purpose. Beyond standard tensile, peeling, and tearing tests for soft packaging and films, the C610M can easily be configured with custom 3-point bending fixtures to execute ISO 178 tests. Continue reading
Residue on Ignition (ROI), described in USP <281>,is a widely used test for determining the amount of non-volatile inorganic residue remaining after a sample is ignited under specified conditions.
Although the procedure may appear straightforward, several steps—including sample charring, sulfuric acid treatment, ignition temperature control, cooling, and repeated weighing—can have a direct impact on the final result.

The EU Packaging and Packaging Waste Regulation (PPWR) fundamentally transforms packaging design from a linear model focused purely on product protection and cost to a circular lifecycle model. To navigate strict mandates surrounding Design for Recycling (DfR), mandatory Post-Consumer Recycled (PCR) content thresholds, packaging minimization, chemical safety, and structural integrity, manufacturers must implement rigorous material characterization protocols across every stage of development. By systematically combining chemical migration screening, gas and moisture permeability testing, high-speed mechanical profiling, thermal seal window analysis, and non-destructive container closure integrity testing (CCIT), Labthink s portfolio of precision testing instruments provides the empirical data required to validate compliant, high-performance packaging without compromising product shelf-life or processing efficiency.

Whether protecting crisp food products from staleness,pharmaceuticals from degradation, or electronics from corrosion, controlling moisture ingress is paramount.
The standard parameter used to evaluate his performance is the Water Vapor Transmission Rate (WVTR)—the measure of water vapor passing through a material per unit area over a specified time under specific temperature and vapor pressure gradients.
