Abstract: A self supporting film of polyolefinic polymer(s) is described, the film having a first and a second surface where a first exposed surface of the film (A) comprises a polymeric low temperature sealable coating (LTSC) and where the second exposed surface of the film (B) comprises an olefinic polymer capable of forming a seal to the LTSC at a minimum temperature of at most about 100° C. when measured at 15 psi for 2 seconds, such that the first and second surfaces of the film have a mutual heat seal strength (A to B) of at least about 200 g/25 mm, when measured at 15 psi for 2 seconds at 120° C.; where the LTSC also comprises: (a) an anti-block additive in from an effective amount to about 15% by dry weight of the coating (b) a non-ionic anti-mist additive having an HLB value of up to about 20; and (c) optionally an anti-slip additive of a mean particle size of from about 3 to about 5 microns in an effective amount up to about 0.5% by dry weight of the coating.

Abstract: Therefore broadly in accordance with the invention there is provided a sheet like substrate comprising a substantially non-polar material having coated onto at least one side thereon an anchor coating to aid subsequent coating thereon of a polar coating and/or layer, characterised in that the anchor coating comprises (a) a polymer comprising an optionally substituted ?, ? carboxylic acid optionally of high acid value preferably the polymer having a low Tg; (b) a polymer comprising an optionally unsubstituted ?, ? carboxylic acid optionally of low acid value preferably the polymer having a high Tg; (c) a cross-linker, preferably added after a period of time to a mixture of polymers (a) and (b) to cross-link the resultant coating composition and increase the Tg thereof. Preferably films of the invention provide directly on the anchor coating; a further polar coating or layer.

Abstract: There is described a polymer film preferably selected from polyolefin, polyester, polyamide, acrylic, polystyrene, or polyurethane, where the film is coated with an ink-jet printable ink receiving layer which when ink-jet printed has an average percent increase in droplet size on the ink receiving layer of less than about 5% between about 0.2 and about 2.0 sec after printing.
