Abstract
The invention relates to a multilayer composite film which is substantially free from polyvinyl chloride and polyolefins. In particular, the layers of the film may include an ABS material, a polystyrene material, and/or a polyester material. The material composition and thickness of composite film are such that the maximum tensile force generated when a test body including the composite film is subjected to a specified single-axis tensile testing procedure ranges between 30 Newtons and 280 Newtons.
