拉伸纏繞膜廠家表示，如果想要拉伸膜獲得好的印刷適應(yīng)性，那么薄膜的張力就要高于油墨的張力，同時(shí)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.

有的拉伸膜雖然表面張力與油墨張力相當(dāng)甚至更高，但其表面光滑，無(wú)毛細(xì)孔表面吸附力小，同時(shí)各種拉伸纏膜在合成樹(shù)脂時(shí)添加的開(kāi)口劑、抗靜電劑、耐老化劑等，也會(huì)影響薄膜的表面性能，使其印刷適性變差。大部分的拉伸膜都存在印刷適性的問(wèn)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適性，就要對(duì)印刷性能差的薄膜表面來(lái)進(jìn)行合理的預(yù)處理，以使膜表面的張力與吸附力慢慢提高。更多有關(guān)于拉伸膜的相關(guān)知識(shí)，歡迎大家前來(lái)咨詢，我們將竭誠(chéng)為您服務(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.
