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.

Abstract: A multi-layer film including: (a) a substrate layer of a thermoplastic polymer film having opposed first and second surfaces; and (b) a heat sealable layer associated with the first surface of the substrate and including (i) a first acrylic polymer and (ii) a second polymer which is a copolymer including residues derived from one or more olefinically unsaturated monomers and residues derived from one or more olefinically unsaturated monomers which include one or more functional groups. The first polymer (i) has a glass transition temperature in the range of from 40 to 120° C. and a weight average molecular weight in the range of from 20,000 to 60,000, the second polymer (ii) is a copolymer of a C1-C4 olefinically unsaturated hydrocarbon and an olefinically unsaturated carboxylic acid, and the heat-sealable layer includes from 5 to 60% by weight of the first acrylic polymer and from 40 to 95% by weight of the second polymer.
