The expanded polyethylene films produced by Proxital are widely used in the packaging sector because they are able to combine the scratch-resistant characteristics of flexible plastic films with protection against crushing and impact thanks to the micro-bubbles of air that compress, absorbing the energy generated by the impact as they are distributed in a concentrated and uniform manner over the entire height.
Particularly in industrial mass production where objects produced are stacked, laid or placed close together in containers, foam is absolutely the most suitable product as a separator due to its unique characteristics. Scratch protection is guaranteed even with minimum thicknesses while, with regard to impact, the choice of thickness is a function of the mechanical stress the film exerts. The greater the impact force against the object, the greater the film thickness must therefore be.
