What is yield point?
The yield point is the point on a stress-strain curve where a material begins to deform plastically. Before this point, deformation is elastic and reversible. Beyond it, the material undergoes permanent change.

What is torque testing?
Torque testing measures the rotational force required to turn or twist an object. In packaging, it is most often applied to closures such as caps, lids and twist-top mechanisms to ensure they open and close within defined performance limits.

What is fastening torque
Fastening torque refers to the rotational force applied to tighten a fastener, typically measured in Newton-metres (N·m) or pound-force inches (lbf·in). The correct torque value ensures adequate clamping without overstressing components.
