ORACAL 451 Banner Cal
Highly flexible special PVC film with silk-matt surface.
Silicone coated paper on one side, 137 g/m², which provides excellent waste-stripping properties. For white vinyl a light blue silicone paper is used to form a stronger contrast to lettering.
Solvent polyacrylate, permanent
Area of use
Specially developed for short- and medium-term lettering and decoration on tarpaulins, transparents and other flexible plastic surfaces. To ensure a stress-free adhesion, wet application is generally recommended. Substrates should be cleaned with spirit or isopropanol, prior to adhesion. Pay attention to complete drying. Additionally suitable for thermal transfer printing (with resin ribbons).

Due to the wide variety of tarpaulins existing in the market own tests before application are absolutely
necessary. Generally recommended are tarpaulins with a surface lacquer finish as plasticiser barrier. The batch traceability according to ISO 9001 is possible on the basis of the roll number.
