RIGID FILMS

Applications

Clear rigid film is primarily produced by calendering or flat die extrusion and the high temperatures and shear forces need PVC formulations capable of providing crystal clarity and sparkleness, as well as freedom from flow lines.

 

Stabiliser Requirements

Careful stabiliser dosing and lubrication is necessary to optimise melt flow characteristics and anti-sticking properties during processing.

A large proportion of rigid PVC film is used for food- or pharmaceutical packaging, so it is necessary to use only the approved stabiliser systems. Films for delicate food require special stabilisers to maintain original taste and smell (organoleptic properties).
