<p>Oriented polyolefin (especially polypropylene) film having antistatic properties is produced by applying to the cast extrudate a solution of an 'Ethomeen' sulphate (e.g. 'Ethomeen' T/12 sulphate) before heating and stretching the extrudate to orient it. The corresponding hydrochlorides are not effective. Inclusion of a quaternary ammonium compound, such as choline chloride, in the solution confers improved antistatic properties.</p> |
