Abstract
Nylon resins are extrusion coated onto various substrates for the manufacture of coated packaging films by heating the nylon resin to a melt temperature of 450.degree.-550.degree.F, extruding the molten resin onto a chill roll through a die which is set at an angle to the chill roll, employing sub-atmospheric pressure between the extruder die and the chill roll, rapidly cooling the extruded film on the chill roll to form a substantially amorphous nylon, and thereafter joining the nylon to a substrate.
