5 Layer Technology

5 layer Technology silage film. What is it? What difference does it make to the ensilaged crop? As with most products, there are differences in the types of silage stretch film available on the market. Silage film can be manufactured either as a mono (single) layer film, or as a 3-layer film and more lately, as film manufacturing technology has advanced, as a 5-layer film. Why is this advanced film technology important to baled silage production? Why should a farmer or contractor choose 5 Layer Technology film?

To the naked eye one film appears to be the same as the next. Not necessarily so. With
5 Layer Technology there are 5 distinct parts (or layers) to a stretchfilm. As such manufacturers have more control over where to place the important elements of a balewrap film. In doing so the film's performance is maximised resulting in a reliable, stable, high performing quality balewrap.

In order to provide the ideal ensiling environment silage stretchfilm needs to offer a number of important elements such as strength, puncture and tear resistance, elasticity, UV stability and the ability to cling in all circumstances. If just one of these features is missing a film will not perform effectively. 5 Layer Technology optimises these elements to provide the best collective performance.

For example, the 5 layer manufacturing process means that specific raw materials within the blend can be directed to that part of the film where they are most needed. So, UV stabilizers are placed on the outer surface of the film to face the weather; tack is placed on the inside face to aid a perfect seal and the mechanical strength, tear and puncture resistance elements form the nucleus of the film.

This highly effective 5 layer structure combines to form a superior, high performing stretchfilm that is robust enough to withstand the rigourous handling of modern, complex wrapping machinery. Such optimised films are better placed to withstand the tough, stemmy crops often selected for ensiling. Additionally, the film's oxygen barrier is improved meaning it has better resistance to oxygen ingress - a feature which is critical to successful ensiling.
