The biggest segment in the plastics packaging industry is certainly tubular bag packaging. From chocolate bars to medical secondary packaging, products are packaged using this technology. Secure marking of expiration or sell-by dates is essential.

Marking of expiration or sell-by dates on tubular bag packagings
Reliable usage of quick-drying UV-curing inks

Openair® Plasma treats packaging at just the right spot for optimum ink bonding, to ensure that printing ink applied by the ink jet process will adhere securely. Modifying the surface tension effectively increases the wettability of the film packaging. In particular, quick-drying UV-curing inks can be reliably used with this pretreatment.
