Tape usually consists of a backing coated with a combination of a rubber or rubber-like " stretchy" component, and a compound called a tackifier.

胶由包被了聚合物的附着物，如橡胶聚合物或是橡胶的有弹性的聚合物，和一种名为增粘剂的化合物组。

A tape's stickiness is determined by the proportion of elastic component and tackifier, the thickness of adhesive spread onto the backing, and the type of backing material.

一个胶的粘性取决于弹性分和增粘剂的比例、和粘着剂在附着物上的扩散厚度、以及附着物材料的种类。
