<p>The present invention provides a film produced by forming a bubble from a composition comprising: (a) up to about 99.9 weight percent based on the total weight of the composition of a polyamide; and (b) at least about 0.1 weight percent based on the total weight of the composition of a polyolefin having functional groups which are reactive with the functional groups of the polyamide wherein the functional groups of the polyolefin are present in an amount sufficient to maintain the strength of the bubble. The film is particularly useful as a carrier film in the production of sandwich composites of sheet molding compound and thick molding compound.</p> |
