Abstract: Described is a multilayer film laminate having at least three layers, and gas barrier properties. The multilayer film laminate comprises sequentially: (I) at least two first layers, each of the first layers (I) having, on one side only, a vapor deposited coating selected independently from the group consisting of aluminum, SiOx and a metal oxide of main group 2 or 3 of the periodic table of the elements; and (II) an exterior polyolefin heat sealing layer. Also described is a method of using the multilayer film laminate as a barrier film in vacuum insulation panels.

Abstract: Described is a process for the homogeneous surface activation of a material in web form, by means of plasma-treatment. The material in web form is selected from metallic materials in web form having a thickness of less than 100 &mgr;m, polymeric materials in web form and combinations thereof. The process involves treating homogeneously at least a portion of the surface of the material in web form, which is moved over at least one pair of rolls, with an atmospheric plasma, optionally in the presence of a process gas and/or a process aerosol. The atmospheric plasma is generated by an indirect plasmatron.
