A crease stiffness tester evaluates paper/board resistance to bending along pre-creased lines, critical for packaging design and durability testing. This article outlines key standards, technical specs, operational mechanics, and testing principles to guide users in optimizing material performance and quality control.
The tester adheres to global protocols like ISO 12192 (creasing resistance), TAPPI T824 (fold endurance), and GB/T 22363 (paper crease stiffness). Compliance ensures reliable data for industry certifications and material benchmarking.
| Paraméter | Specifications |
|---|---|
| Measurement Range | 0.1-20 mN·m (adjustable) |
| Szanálás | ±0.01 mN·m |
| Crease Angle | 90°, 135°, or 180° (selectable) |
| Sample Size | Standard (e.g., 150×30 mm) or customizable |
| Adatkibocsátás | Digital display, USB export |
The tester applies controlled force to bend a pre-creased sample, measuring the resisting torque via sensors. Software calculates stiffness (mN·m) to quantify the material’s ability to maintain structural integrity post-creasing.
Simulating real-world folding stresses, the test assesses how well paper/board withstands repeated creasing. Results aid in designing durable packaging, reducing product damage, and ensuring compliance with performance standards.
This guide equips industries to enhance material resilience, optimize packaging designs, and ensure adherence to global quality norms through precise crease stiffness testing.
