Abstract Haze (H) is not an accumulative property based on the addition of internal haze (Hi) and surface haze (Hs) parameters, though the relation (Hs = H − Hi) is widely accepted and used nowadays in research and development of plastic films. To evaluate the correct relation, the analytical relation between the total haze (H) and the haze of a single film (hi) in the film superposition model was firstly concluded, which is 1 − H is equal to the product of 1 − hi of every single film. This relation was validated by the experimental results using thin films of different kinds of polymers with different hazes. Based on this relation, the expression of surface haze was concluded. When the two surfaces of a film were the same, the haze of the single surface Hs¯=1−(1−H)/(1−Hi). $\overline {{H_{\rm{s}}}} = 1 - \sqrt {(1 - H)/(1 - {H_{\rm{i}}})} .$ The mathematical relation between haze and thickness was also obtained.

一种计算表面雾度的新方法

摘要 雾度 (H) 不是基于内部雾度 (Hi) 和表面雾度 (Hs) 参数相加的累积特性，尽管 (Hs = H − Hi) 关系已被广泛接受并在当今塑料研发中使用。电影。为了评估正确的关系，首先得出薄膜叠加模型中总雾度（H）和单个薄膜的雾度（hi）之间的解析关系，即 1 − H 等于 1 − hi 的乘积每一部电影。使用具有不同雾度的不同种类聚合物的薄膜的实验结果验证了这种关系。基于此关系，得出表面雾度的表达式。当薄膜的两个表面相同时，单个表面的雾度 Hs¯=1-(1-H)/(1-Hi)。$\overline {{H_{\rm{s}}}} = 1 - \sqrt {(1 - H)/(1 - {H_{\rm{i}}})} 。
