滚轮热封包装系列ABC之六：应力——应变曲线及弹性模量

Series Sixth of Roller Heat Sealing Packaging：Stress - strain Curves and Elastic Modulus

在滚轮热封制品封口处的压痕处，复合薄膜的平均形变率在5％以上，个别制品的平均形变率有可能达到50％的水平。因此，研究基材及复合薄膜的应力——应变曲线非常重要。

In the indentation of the roller seal sealing products, the average deformation rate of the laminated film is more than 5%, the average deformation rate of some products are likely to reach the 50%. Therefore, it is of great importance to study the stress-strain curve of the substrates and the laminated film.
