摘　　要：本文就拉伸工艺对PETG热收缩膜收缩力的影响展开了研究。研究结果表明:随着拉伸温度的升高和拉伸时间的延长,薄膜的收缩力有一定程度的降低;随着定型温度的升高和定型时间的延长,薄膜的收缩力也会降低;增大横向拉伸比,薄膜的收缩力增大。The effect of drawing process on the shrinkage force of PETG heat shrinkable film was investigated.The results show that with the increase of tensile temperature and elongation of tensile time,the shrinkage force of the film decreases to some extent.With the increase of setting temperature and the extension of setting time,the shrinkage force of the film will decrease.The shrinkage force of the film increases with the increase of the transverse tensile ratio.

关 键 词：拉伸温度 定型温度 拉伸比 收缩力
