The present invention discloses an improved multilayer polymer film. The film may comprise a first skin layer (31), a second skin layer (32), and an intermediate layer (33) between the skin layers. The first layer, the second layer and the intermediate layer can be formed from the respective first polymer composition, second polymer composition and intermediate polymer composition. Each layer may have titanium dioxide particles distributed therein in an amount of 6% to 14% by weight. One or both of the second skin layer (32) and the intermediate layer (33) may have non-white pigment particles distributed therein in an amount of 0.050% to 0.15% by weight of these layers. The content and distribution of the pigments between layers can provide a relatively disproportionate improvement in opacity, while preserving a neutral white color surface to receive ink printing, resulting in a high degree of color consistency with the target color, and preserving the solderability of the film itself . |
