前言:高聚物的等温和非等温的热收缩型薄膜在应用数量上发展很快,这种薄膜首先是使用简单,它的收缩力是取向高聚物的完全松弛的过程。它提供三个特殊的参数来控制不同的收缩薄膜材料。在等温条件下,收缩时间,收缩的恒定性,和能收缩的极限是三个参数选择的结果,通过连续提高温度 Introduction: The isothermal, non-isothermal, heat shrinkable films of polymers rapidly develop in number of applications. The film is simple to use and its shrinkage force is the complete relaxation of the oriented polymer. It offers three special parameters to control different shrink film materials. Under isothermal conditions, the shrinkage time, the constant shrinkage, and the shrinkage limit are the result of three parameter choices. By continuously increasing the temperature
