Standards and compliance
International standards ensure penetration and puncture testing is performed consistently for reliable and comparable results.
Key examples include:

Introduction to friction in material science
Friction is a critical factor in how materials behave under movement. It is the resistive force that occurs when two surfaces are in contact and attempt to slide against each other.

Interpreting breakaway test results
Understanding test outputs is as crucial as conducting the tests themselves.
Slip torque vs bridge torque
Slip torque reflects the resistance encountered before rotation begins—a measure of seal integrity and usability.

Applicators and dispensers
Applicators and dispensers are designed to provide uniform coverage of semi-solids, liquids and viscous matter such as creams and lotions. They are often integrated with the product's packaging so that the packaging also acts as a dispenser.

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.
