A self-adhesive surface protective film, particularly for automobile paint surfaces, having a backing layer and a self-adhesive layer based on a crosslinked polyurethane, characterized in that the loss angle tan &#x3b4; of the polyurethane at room temperature in the frequency interval from 10to 10rad/sec rises or remains at the same level.

Surface protecting film for painted surfaces, comprising polyurethane-based pressure-sensitive composition

Device for unrolling one-sided self-adhesive material (12) located on a roll (1), comprising two holders (2), each of which has a cut-out (21) to accommodate the roll (1) and which are arranged in such a way that they form a slotted guide for the roll (1) located between them, a driven draw-off roll (5), which has elastic material (52) wound around it and is arranged in such a way that the material (12) is drawn off the roll (1) using the non-adhesive side over the draw-off roll (5), the roll (1) being held by the slotted guide in direct contact with the draw-off roll (5) over the entire width of the roll (1).
