Uni-Foam is Selig's range of expanded polyethylene lining materials which provides a clean and excellent solution for general purpose sealing of bottles when used to line both plastic and metal closures. Expanded polyethylene (EPE) is a dust free, non-absorbent sealing solution. Selig's material remains unaffected by ambient temperatures and does not support mould growth. The smooth white surface adds value to the appearance of the packaging and a wide choice of densities, thicknesses and facings permit the effective sealing of even the most irregular neck finishes, or aggressive of products. A variety of facings can be applied which offer improved barrier performances and can be supplied as pre-cut liners or tape.
