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.
