Films may be used as interleaves between hard and non-compressible surfaces such as surfaces of sheets or plates made of glass, metal, such as steel, polycarbonate, and/or poly(methyl methacrylate). The films may be embossed and/or may include a foamed core layer having a plurality of micro-voids. In particular, the films may include a polyolefin, a basis weight of between about 30 gsm and about 70 gsm, an embossed thickness of between about 150 microns and 800 microns, and a stiffness of between about 150 grams and about 750 grams according to the Circular Bend Stiffness Test. 膜可以用作坚硬且不可压缩的表面例如由玻璃、金属如钢、聚碳酸酯和/或聚(甲基丙烯酸甲酯)制成的片或板的表面之间的夹层。该膜可以是压纹，和/或可以包括具有多个微空隙的发泡芯层。具体地，该膜可以包括聚烯烃，约30gsm至约70gsm的基重，约150微米至800微米的压纹厚度，和根据圆形弯曲刚度测试约150g至约750g的刚度。
