摘要： The present invention relates to a polymeric film, which may have but is not limited to Biaxially oriented polyester, polypropylene & polylactic acid that has a soft-touch matte coating applied via an in-line coating process. This film also has an increased coefficient of friction of this surface, with a total thickness from 5 to 80 μm. The film of this invention has excellent suitability as external packaging bags with an excellent matte appearance and soft haptic feel which, when the bags are stacked A side to A side (A side being coated), are not subject to slippage between the same. At the same time, this film has also low friction with metal, so it is easy to handle the film in the film making process which contributes to the excellent productivity.
