Abstract
This invention relates to a formulation for making a composite plastics film or sheet comprising a polyolefin, a filler and a voiding agent, characterised in that the voiding agent is a pentaerythritol ester of maleic rosin. This is particularly suitable for use on the printable surfaces of synthetic paper. A feature of this rosin is that it minimises the yellowing of the paper.
