拉伸纏繞膜廠家表示，如果想要拉伸膜獲得好的印刷适應性，那麽薄膜的張力就要高于油墨的張力，同時表面要有(yǒu)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(yǒu)的拉伸膜雖然表面張力與油墨張力相當甚至更高，但其表面光滑，無毛細孔表面吸附力小(xiǎo)，同時各種拉伸纏膜在合成樹脂時添加的開口劑、抗靜電(diàn)劑、耐老化劑等，也會影響薄膜的表面性能(néng)，使其印刷适性變差。大部分(fēn)的拉伸膜都存在印刷适性的問題。

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.

我們要想提高膜表面的印刷适性，就要對印刷性能(néng)差的薄膜表面來進行合理(lǐ)的預處理(lǐ)，以使膜表面的張力與吸附力慢慢提高。更多(duō)有(yǒu)關于拉伸膜的相關知識，歡迎大家前來咨詢，我們将竭誠為(wèi)您服務(wù)！

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.
