| Popis: |
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 DEG 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 200g/25 mm, when measured at 15 psi for 2 seconds at 120 DEG 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. |
