NoteSurfaces to which the material will be applied must be thoroughly cleaned from dust, grease or any contamination which could affect theadhesion of the material. Freshly lacquered or painted surfaces should be completely cured. The compatibility of selected lacquers andpaints should be tested by the user, prior to application of the material. Films with structured surface are naturally more sensitive than theunstructured. Accordingly, these films are to be treated carefully both in processing and in cleaning. Impurities affect the appearance ofstructured films and require more frequent cleaning. Furthermore the application information published by ORAFOL is to be considered. The
batch traceability according to ISO 9001 is possible on the basis of the roll number.
