ABSTRACT OF THE DISCLOSURE A PVC film with a non-tacky microcell surface on one side is provided which does not adhere to any smooth surface such as photographs, slides, negatives and other materials requiring covering for protection such as in photo-albums, slide-sheets, negative-albums, and X-ray film covers where a slightly opaque surface is needed to protect the materials from damage caused by direct light. A film is specifically treated to provide microcells on one surface thereof which avoid adherence of the film to smooth surfaces. These microcells are made possible by application means or mechanical means. The microcells formed are an integral part of the original film, and cannot be defined as to structure or size since the same are of an irregular nature.
