Beschreibung
Zusammenfassung:	This disclosure provides compositions and methods for a film, which may include a base film and a coating layer on the base film, wherein the coating layer has a surface energy of at least 30 dynes/cmand consists essentially of nylon, polyester, ethylene vinyl alcohol-based copolymer, polyvinyl alcohol-based polyethylene terephthalate, polyvinylchloride, acrylate-based polymers, methacrylate-based polymers, polyurethane, polyalkylimine, acid-modified polyolefins, polyetherester-amide block copolymer, and combinations thereof. Further, the film may include a metal oxide layer on the coating layer, wherein the metal oxide layer has an optical density of equal to or less than 0.5 and a thickness from 0.1 nm through 100 nm. Further still, the film has an oxygen transmission rate of less than4 cm /m /day at 23 DEG C and 0% relative humidity, a water vapor transmission rate of less than 4 g/m /day at 38 DEG C and 90% relative humidity, and a thickness of 5 mu m through 50 mu m. 本发明提供了用于薄膜的组合物和方法，该薄膜可包括：基础薄膜和在该基础薄膜上
