Zusammenfassung:	An inkjet printable flexible film for packaging applications is provided which comprises (a) a biaxially oriented polymer film having a thickness in the range of from 8 to 70 µm; and (b) at least one ink-receiving layer comprising boehmite particles and poly(vinyl alcohol) having a degree of hydrolysis of from 78 to 96 mol % in a weight ratio ranging from 6.5:1 to 20:1 coated over one surface of the biaxially oriented polymer film at a dry coating weight being in the range of from 5 to less than 25 g/m2, wherein the ink-receiving layer (b) is formed by (i) applying an aqueous coating composition comprising boehmite particles, an acidic dispersing agent, poly(vinyl alcohol), and boric acid and/or a borate, or (ii) applying boric acid and/or a borate in a first step and then an aqueous coating composition comprising boehmite particles, an acidic dispersing agent, poly(vinyl alcohol), and optionally further boric acid and/or borate. The packaging applications include the packaging of food, pet food, beverages, pharmaceuticals and/or personal care products.
