Beschreibung
Zusammenfassung:	A multi-layer film comprising a thermoplastic barrier layer, and a seal layer. The seal layer being an ethylene copolymer, having in the range of from about 5 to about 12 mol percent of a comonomer selected from the group consisting of vinyl acetate, ethyl acrylate, methyl acrylate and butyl acrylate. The multi-layer film is RF weldable in the range of from about 10 to about 50 MHz to form a non-peelable seal and where the seal layer has an anti-block matted surface.
