摘要 |
<p>A composite film, particularly a polyester film, comprising a substrate layer and a heat-sealable layer comprising a particulate additive, exhibiting an improved combination of handling and heat-sealable properties. The exposed surface of the heat-sealable layer has greater than 100 surface protrusions per mm<2> produced by the particulate additive. The surface protrusions have an average peak height in the range from 5 to 400 nm measured from the average level of the surface of the heat-sealable layer.</p> |
