Type: ML OPP sealable and metallised film 20my

OPP ML Film is a metallized BOPP film. This film is heat-sealable with low seal initial temperature and has good slip properties and improved barrier properties for WWTR and OTR. The main charecteristics of the film are good flatness combined with a broad heat seal range and good hot-tack for high speed applications.

- Metallized side is wound outside
