Load Containment Testing

Containment Force is essentially the binding pressure that secures your load, ensuring stability and safety during transit. It is determined by the combination of the number of stretch film revolutions and the wrap force, or tightness. This critical specification plays a pivotal role in minimising damage and guaranteeing that loads are safe for shipping. 

Here at FROMM, we use a specialised testing cube to determine what pre-stretch level and wrapping machine settings will provide the best balance of puncture resistance and load containment. 

During the testing process, we collect data that can be graphically represented to illustrate the compression force the film applies to the load during wrapping, the puncture resistance of the finished wraps, and the resistance to further stretching of that wrapped film (containment force) over time. Additionally, we assess the force necessary to stretch the film. The data can be visualised in real time graphs, allowing us to observe changes at various stages of the cycles.
