Handling instructions
PLEXIGLAS® extruded acrylic sheet according to ISO 7823-2

Function of the masking film
PLEXIGLAS® solid sheet is normally protected on both sides with masking film. This mainly serves as protection against mechanical damage and soiling during transportation and handling.
Masking film frequently offers additional properties that have proved useful during subsequent processing of PLEXIGLAS® (especially solid sheet).

Different film types
Masking films for PLEXIGLAS® solid sheets are generally made from polyethylene (PE). The type of film, film thickness and adhesion are selected according to common market requirements. Care is always taken to use the masking film that offers the widest scope for fabrication.
Film type Adhesion Level Products Characteristics/Application Cling film (SH-) Medium – highly uniform Extruded and cast PLEXIGLAS® SH film has no adhesive on the cling side and can be applied by either warm or cold lamination. SH film is suitable for cut-to-size sections and can be used for thermoforming under certain conditions. Self-sealing film (SK-) Medium – strongly dependent on the adhesive layer Preferably cast PLEXIGLAS®, but also extruded (incl. PLEXIGLAS® Satinice) SK film offers strong adhesion due to an additional adhesive layer on the adhesive side. The film can be re-adhered after removal. It is especially suitable for small cut-to-size sections where it is important for the film to re-adhere to the PLEXIGLAS® sheet. Adhesion between the PLEXIGLAS® sheet and the masking film is achieved by special adhesive constituents in the PE or additional adhesive layers.
