Abstract:
1. A continuous partially metallized packaging film sheet comprising: a width running laterally between two outer edges; two metallized opaque film strips, wherein each said opaque film strip has an outer edge adjacent to one said outer edge of said packaging film sheet, and has a constant width running between said outer edge and an inner edge; two partially metallized translucent film strips, each translucent film strip comprising an outer edge, an inner edge, and a width running between said outer and inner edges, and wherein said outer edge of each said translucent film strip is adjacent to one said inner edge of said opaque film strips, and wherein said translucent film strips are partially metallized by less exposure time to a vaporized metal stream than said opaque film strips, thereby producing said translucent film strips; and a non-metallized transparent film strip disposed between said translucent film strips, wherein each said partially metallized translucent film strip provides a gradual transition from each said metallized opaque film strip to said non-metallized transparent film strip.
