拉伸缠绕膜厂家表示，如果想要拉伸膜获得好的印刷适应性，那么薄膜的张力就要高于油墨的张力，同时表面要有一定的粗糙度以形成吸附力。

The manufacturer of stretch winding film said that if you want to stretch the film to obtain good printing adaptability, the tension of the film must be higher than that of the ink, and the surface must have a certain roughness to form adsorption.

有的拉伸膜虽然表面张力与油墨张力相当甚至更高，但其表面光滑，无毛细孔表面吸附力小，同时各种拉伸缠膜在合成树脂时添加的开口剂、抗静电剂、耐老化剂等，也会影响薄膜的表面性能，使其印刷适性变差。大部分的拉伸膜都存在印刷适性的问题。

Although the surface tension of some stretch films is equal to or even higher than that of the ink, their surface is smooth and free of pores. At the same time, the opening agent, antistatic agent and anti-aging agent added by various stretch films in the synthesis of resin will also affect the surface properties of the films and make their printability worse. Most stretch films have printability problems.

我们要想提高膜表面的印刷适性，就要对印刷性能差的薄膜表面来进行合理的预处理，以使膜表面的张力与吸附力慢慢提高。更多有关于拉伸膜的相关知识，欢迎大家前来咨询，我们将竭诚为您服务！

If we want to improve the printability of the film surface, we must carry out reasonable pretreatment on the film surface with poor printing performance, so as to slowly improve the tension and adsorption of the film surface.
