Abstract

The present invention relates to thermoplastic film having improved tear resistance, puncture resistance, and enhanced control of the film's elongation when subject to an applied load. The film can have an emboss pattern comprising a plurality of embossed regions, each embossed region comprising a plurality of closely spaced, non-intersecting sinusoidal shaped embosses. A sinusoidal emboss of an embossed region can be divided into three sections, wherein for each section along the emboss, the cross and machine orientation of the film can vary due to formation of the emboss. The emboss pattern can be arranged into various sections, wherein the amplitudes of the sinusoidal embosses of an embossed region can vary from one section of the pattern to another. The overall geometric shape of the embossed regions can also vary from one emboss region to another.
