The present invention provides a pigmented thermoplastic film comprising one or more mineral filler agents at an amount effective to prevent or reduce the occurrence of discolouration when the film is stretched and/or to prevent or reduce the loss of the mechanical properties of the film, such as elasticity, stretchability, tear resistance, or perforation resistance. Also provided is a process and a composition for manufacture of such films. The films of the present invention are useful for industrial packaging, especially with automatic wrapping machines, but may be used to wrap any product for shipping or storage.
