PURPOSE: To improve printability, ink setting properties and ink drying properties by providing a coating layer containing a specific prolyolefinic resin and porous particles on the surface of a plastic film.
CONSTITUTION: A coating layer containing a linearly irregularly arranged polyolefinic resin with a wt. average mol. wt. of 1000-50000 consisting of 65-99 mol% of an ethylene structural unit represented by formula I, 0-15mol% of an acrylate structural unit represented by formula II (wherein R1 is a 1-4C alkyl group) and 1-35mol% of an acrylamide structural unit represesnted by formula III (wherein R3 and R4are a 1-4C alkyl group, R2 is a 2-8C alkylene group, R5 is a 1-12C alkyl group, an arylalkyl group or an alicyclic alkyl group and X is a halogen atom, CH3OSO3 or C2H5OSO3) and porous particles with oil absorption of 200-400ml/100g is provided on at least the single surface of a plastic film. By this constitution, excellent printability, ink setting properties, ink drying properties, ink adhesion and water resistance are obtained.
