Case Study:
Holding force and load stability for Stretch Hood

The truth about the holding force and load stability correlation

It is a common assumption that a film with higher holding force offers higher load stability, but why is this? In this case study we break the myth, by exploring the relationship between holding force and load stability.

The challenge

To understand this apparent correlation, we conducted a benchmarking exercise of various stretch hood films existing in the marketplace today, at our Load Stability Innovation Center in Pack Studios Tarragona. We didn’t just measure film properties in the laboratory; we ran films on stretch hood lines and evaluated load stability, and the results were very surprising.

The solution

We designed a new, non-EVA based stretch hood film, with improved physical performance, while maintaining or improving the load stability performance*.

Furthermore, the more elastic films are easier to apply, addressing problems such as tiger striping, film holing and thinning.

The result

There is a correlation between holding force and load stability, but not the one that we expected. To our surprise, the study revealed that higher holding force films actually resulted in more pallet deformation.

The test setup

For this case study, we used 11 layers of 5 sacks stacked onto a pallet. Each sack contained 25kg of PE resin. The load was attached to the pallet with a stretch hold film and the total dimensions of the stacked the pallet 1230mm wide X 1100mm deep X 1900mm high.
