如背面中央有接缝，则印在右下方或印在填充后不起皱折、不变形处；真空包装抽真空后包装袋紧贴在内容物表面，呈不规则立体形状，表面不平整，会造成条形码变形不能识读，因此真空包装内袋不宜直接制卡和会员卡制作条形码，可增加一个外包装袋制卡和会员卡制作条形码及其他图文。

The 3D topography of fractured surfaces was reconstructed and quantified by the means of SEM stereo pairs, image processing and analysis, and computer vision. It was shown that measured 3D roughness indexes Rs, Rq and Rmax have good positive relations to the crack propagation part of absorbed impact energy. Although fractal behavior had been checked out on the fractured surfaces, the fractal dimension was found nonsensitive to the fracture mode and mechanical properties. The geometric characteristics of fractal fractured surfaces should be quantified in fractal dimension together with absolute parameters.
