Zusammenfassung:	Polymer blend useful in making release liners, especially for reflective sheeting, comprises: A. a matrix polymer (e.g., a polyolefin); B. a filler such as CaCO3; C. a fluorocarbon, such as a 2-oxazolidinone compound. Typical proportions are: polypropylene 54.5%, CaCO3 45%, and flourochemical oxazolidinone 0.5%. Liners made of this composition can be used both in the process of manufacturing reflective sheeting and as release liners on finished product, thus combining process and product liner into one. They can also be used as a slip sheet in bonding reflective sheeting to sign blanks or substrates.
