QSK - Retrafilm is a very light transparent polyester film covered with an aluminum veil which, if properly stretched, creates a mirroring surface of excellent quality.
The film is thermosensitive, it shrinks at temperatures above 70 °C, a property that is used to stretch it perfectly on special aluminum frames, creating mirror panels characterized by extreme lightness, exceptional sharpness of reflection, absence of danger and transparency in backlighting (lower than that of QSM - Magic Mirror Film).
The film strips can be joined with a transparent adhesive tape on the back to create crumpled backdrops with original reflective characteristics, very sensitive to air movement and slightly noisy.
The film is very resistant to traction and not very resistant to tearing.
