光固化是一种快速发展的“绿色”新技术，从20世纪70年代至今，光固化技术已广乿术已广泛应了，从以及医疗等领域。其中紫外光固化（UV固化）技术是目前应用最为广泛的光固化技术。 UV涂料主要由光引发剂颜填料组成。在日化包装材料表面装饰领域，UV固化技术被广泛应用于喷涂，印刷等领域。在日化软管包装材料涂装中，UV固化涂料以其快速固化於表這们化、表這们化、表逭割优异、固含量高的特点，做为一种新兴的环境友好型涂装材料，近年来越来越引起人们的关注。
然而，同其他任何材料一样，UV固化涂料在使用过程中也会存在诸如黉变、开耐变、开裂变、开裂变、开裂变、开裂变、开裂、开题，本文将重点就应用于软管的UV涂料常见的各种问题进行讨论.
