Abstract
PURPOSE: To prevent oxidation of polyethylene film, improve adhesion at heat sealing and reduce the offensive odor by placing the unwelded surface of extruded PE film in an inert gas atmosphere in case of polyethylene weld-coating to the substrate.
CONSTITUTION: PE melted and kneaded by an extruder 1 is extruded as film 3 from the die 2 at 300W330°C resin temperature. The gas, preferably nitrogen, is blown out at a jet rate of e.g. 0.5W10m3/hr from the inert gas jet pipe 4 provided with the tiny holes at constant spacing and at least the unwelded surface of melted PE film is subjected to inert gas atmosphere from the die 2 to the cooling roll 5. Melted PE film is welded and coated usually on cellophane etc. as the substrate between the press roll 6 and the cooling roll 5.
