Products or packages are dropped from a predetermined height onto a hard surface using a calibrated Drop Tester.

Using a Peel Strength Tester, a sealed sample is pulled apart at a constant rate while measuring the force required to peel the seal.

Standard-sized plastic samples (typically 1" x 10") are carefully prepared and conditioned before testing. Using a Universal Testing Machine,

A sample of cardboard is cut to standard dimensions, weighed, and then submerged in water for a specified period (typically 5 minutes).

In this test, a defined-size paper sample (typically 4" x 4") is clamped in place and subjected to increasing hydraulic pressure via a rubber diaphragm until it bursts.

A precisely cut sample of corrugated board is placed vertically between two compression plates in the Edge Crush Tester.

The package is placed on a Vibration Tester platform and subjected to controlled vibration profiles for a specified duration.

Sealed packages are exposed to UV or fluorescent light under controlled conditions. Fluorescent dye may be applied to enhance visibility of defects.
