Paperboard-based composites, typically in the form of carton plies, polyethylene, and aluminum foil, are widely used for food packaging applications. The main goal of packaging converting procedures is to create robust and well-shaped commercial packages. This high speed process is very dynamic, resulting in enormous deformation rates within a few milliseconds. In contrast to previous quasi-static investigations, the envisaged dynamic material characterization for soft and thin paperboard plies will help understand and predict the material response during this high speed packaging process. Even though several experimental standards are already available for paperboard tensile tests, these standards are limited to conventional quasi-static test procedures. Specific cylindrical clamps made of aluminum were designed to prevent samples with a thickness of 100 m from slipping. By means of accurate measuring techniques, a maximum strain rate of 80 s^-1 was achieved, which effectively corresponded to actual strain rates that occur in paperboard converting procedures. It was shown that paperboard plies exhibited anisotropic properties and rate-dependent characteristics. Compared to quasi-static properties, the dynamic experiments revealed stiffer hardening properties at higher strain rates. A rate-dependent material model based on Cowper-Symonds and Johnson-Cook analytical laws was generated to formulate a paperboard dynamic constitutive model. Experimental investigations towards analytical material formulations were successfully conducted to predict and determine the rate dependent material characteristics of paperboards plies at high strain rates. 

基于纸板的复合材料，通常采用纸板、聚乙烯和铝箔的形式，广泛用于食品包装应用。包装转换程序的主要目标是创建坚固且形状良好的商业包装。这种高速过程是非常动态的，在几毫秒内产生巨大的变形率。与之前的准静态研究相比，软和薄纸板层的动态材料表征将有助于理解和预测高速包装过程中的材料响应。尽管已经有几个实验标准可用于纸板拉伸测试，但这些标准仅限于传统的准静态测试程序。由铝制成的特定圆柱形夹具旨在防止厚度为 100 m 的样品滑动。通过精确的测量技术，最大应变速率为 80 s达到了^-1，这有效地对应于纸板加工过程中发生的实际应变率。结果表明，纸板层表现出各向异性特性和速率相关特性。与准静态特性相比，动态实验表明在更高的应变速率下具有更硬的硬化特性。基于 Cowper-Symonds 和 Johnson-Cook 分析定律的速率相关材料模型被生成以制定纸板动态本构模型。成功地对分析材料配方进行了实验研究，以预测和确定高应变率下纸板层的速率相关材料特性。
