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