不干胶也叫自粘标签材料，是以纸张、薄膜或特种材料为面料，背面涂有胶粘剂，以涂硅保护纸为底纸的一种复合材料。
Self adhesive, also known as self-adhesive label material, is a composite material with paper, film or special materials as the fabric, adhesive coated on the back and silicon coated protective paper as the base paper.化粪池模具 精密铸造 钢纤维 盐水注射机 风电基础模具 nsk轴承经销商 nsk轴承总代理 保定空调移机不干胶标签大致分为两种:一是纸张类不干胶标签，二是薄膜类不干胶标签。
There are two kinds of self-adhesive labels: one is paper self-adhesive label, the other is film self-adhesive label.
1、纸张类不干胶标签主要用于液体洗涤类产品以及大众化的个人护理产品上;薄膜类材料主要用于中高档的日化产品上。目 前，市场上的大众化个人护理用品及家用液洗产品占有较大比重，所以相应的纸张材料用得较多。
1. Paper self-adhesive labels are mainly used for liquid washing products and popular personal care products; Film materials are mainly used in medium and high-grade daily chemical products. At present, the popular personal care products and household liquid washing products in the market account for a large proportion, so the corresponding paper materials are used more.
2、薄膜类不干胶标签常用PE、PP、PVC以及其它一些合成材料，薄膜材料主要有白色、亚光、透明三种。由于薄膜材料印刷适性不是很好，所以一般会作电晕处理或通过其表面增加涂层来增强其印刷适性。为了避免一些薄膜材料在印刷和贴标过程中变形或撕裂，部分材料还会经过方向性处理，进行单向拉伸或双向拉伸，例如经过双向拉伸的BOPP材料应用相当普遍。
2. PE, PP, PVC and other synthetic materials are commonly used for film self-adhesive labels. The film materials mainly include white, matte and transparent. Since the printability of thin film materials is not very good, corona treatment or coating on its surface are generally used to enhance its printability. In order to avoid deformation or tearing of some film materials in the process of printing and labeling, some materials will also undergo directional treatment for unidirectional stretching or biaxial stretching. For example, biaxially stretched BOPP materials are widely used.
