The present invention is to provide a structural design for a scratch and abrasion resistant film, which is a heat-shrink film having a plurality of predetermined positioning contour lines and holes disposed thereon in accordance with the contour corners of a case and the external parts, such as buttons, antenna, etc., of a communication device so that when the communication device is sleeved in the heat-shrink film and the heat-shrink film is heated to shrink, by means of those positioning contour lines and positioning holes maintaining the alignment with the corresponding contour corners and the external parts on the case, the heat-shrink film is shrunken to the right positions to smoothly cover the case, serving as a protection layer for the case against being directly scratched and attaining the scratch and abrasion resistant purpose.
