Process for the production of multilayer polymer films |
摘要 |
A process for the production of a composite film for use in laminated glazing assemblies comprising at least one layer of a flexible safety film together with one layer of flexible plastic carrier film includes the steps of drawing the layers from separated feed rolls (1, 2), heating to a bonding temperature, and pressing together to form a composite film, whereby the flexible safety film is not under tension when it is pressed together with the carrier film to form the composite film.
