Barrier Films

The barrier films developed by PROCHIMIR are based on polyolefins, TPU, CoPES or CoPA.
They provide barrier properties against industrial or body fluids and water. They also protect against dust, puncture or bumps, play an active role in noise or light insulation.

By controlling the surface tension, the PROCHIMIR barrier films can be printed, foamed, coated or even aluminized.

HF weldable, the TPU films are also a chlorine- and phthalate-free alternative to PVC for inflatables (bladders, inflates, balloons, vessels).

The barrier films may be coextruded to add them one or two layers of adhesives. These engineered structures are to be applied, either on top of a surface or incorporated into a composite structure.

Beyond a customized geometry, PROCHIMIR proposes multiple options : Corona treatment, Colors, Surface finishing, Fire retardancy, Skin contact, UV resistance, FDA agreement…
