Title:
PROCESS FOR PRODUCING TACTILE FEATURES ON FLEXIBLE FILMS
Document Type and Number:
WIPO Patent Application WO/2021/108633
Kind Code:
A9
Abstract:
A process for producing tactile and sealing features on flexible films (40). The temperature of resin (80) is raised until it melts, but below its flash point. Wetting hot roll cylinder (10) with the resin (80) in negative cells (14) and transferring to positive textures (24) in cylinder (20). Transferring part of the thermo resin (80) on cylinder (20) to coacting cylinder (30) and passing a continuous flexible film (40) through coacting hot cylinder (20) and cold cylinder (30). The control of the temperature differential between cylinder (20) and film (40) allows the maximum transfer of resin (80) to form tactile structures. Sealable print areas are also created in film (40) that are particularly useful for packaging applications.
