Abstract
In accordance with the present invention, films of a nylon 6-nylon 6,6 blend are produced by a process which comprises blending about 50 to about 80 percent by weight nylon 6 resin and correspondingly about 50 to about 20 percent by weight nylon 6,6 resin, extruding said blend at a temperature above its melting point onto a smooth moving support to form a coherent film; maintaining said support at a surface temperature in the range of about 230.degree. to about 300.degree. F. and collecting the resultant film. The resultant film has a haze value, as hereinafter defined, in the range of about 5 to about 20 percent, preferably about 8 to about 14 percent. Film having the latter range of haze values is particularly suitable for the production of cooking bags.
