在我們生產拉伸纏繞膜的時候。一般需要對云南拉伸纏繞膜進行分切，實際上纏繞膜分切后的質量卻不是很好，但是一時卻找不出原因，對于這個現象，相信不少人都遇到過。究竟拉伸纏繞膜分切后出現質量問題是什么原因造成的？纏繞膜分切質量受什么影響？

When we produce stretch wound film. Generally, Yunnan stretch winding film needs to be cut. In fact, the quality of winding film after cutting is not very good, but the reason can not be found for the moment. I believe many people have encountered this phenomenon. What are the reasons for the quality problems after the slitting of stretch winding film? What is the effect on the slitting quality of winding film?

1、拉伸纏繞膜膜幅的松懈：云南拉伸纏繞膜膜幅的橫向長短，都不盡相同，如果寬度的改動大于膜幅，為了應對張力的改動，很多縱切后的拉伸纏繞膜會松懈下來，并且由于張力小而缺少挺度和牽引力，這時整個膜幅會發作移位。

1. Relaxation of stretch winding film width: the transverse length of Yunnan stretch winding film width is different. If the change of width is greater than that of film width, in order to cope with the change of tension, many stretch winding films after longitudinal cutting will relax, and lack stiffness and traction due to small tension. At this time, the whole film width will shift.

2、膜卷歪斜形成的移位：即使云南拉伸纏繞膜長度比張力小，也可能引起盯梢問題。一般卷軸比較簡單傾向張力緊的拉伸纏繞膜，拉伸纏繞膜歪斜和牽引力的改動都將形成膜卷移位。

2. Displacement caused by film roll deflection: even if the length of Yunnan stretch winding film is smaller than the tension, it may cause stalking problems. Generally, the reel is relatively simple and tends to stretch the winding film with tight tension. The deflection of the stretching winding film and the change of traction force will form the displacement of the film roll.

3、拉伸纏繞膜復卷軸的引力：由于粘膠和靜電的共同效果，有必要用力才能將云南拉伸纏繞膜從放卷軸上剝下。如果粘力和靜電效果太強或有改動，會直接導致放卷軸的環繞和盯梢問題。

3. Gravity of the rewinding shaft of the stretch winding film: due to the common effect of viscose and static electricity, it is necessary to use force to peel the Yunnan stretch winding film off the rewinding shaft. If the adhesive force and electrostatic effect are too strong or changed, it will directly lead to the problem of winding and stalking.

4、復卷積累形成的松懈：鎖閂環繞對卷軸直徑改動敏感，由于不是差式復卷，放卷軸能夠以不同的旋轉速率運作，云南拉伸纏繞膜越薄，卷軸直徑越小，卷筒拉伸纏繞膜的積累越少，成果就導致了拉伸纏繞膜膜卷的松懈和移位。

4. Looseness caused by rewinding accumulation: the latch surrounding is sensitive to the change of reel diameter. Since it is not differential rewinding, the unwinding reel can operate at different rotation rates. The thinner the stretch winding film in Yunnan, the smaller the reel diameter, and the less the accumulation of stretch winding film on the reel, resulting in the looseness and displacement of stretch winding film.

無錫拉伸纏繞膜分切位置分切位置是指分切切刀的下刀位置。任何分切機都有一定的分切偏差，為保證產品圖案的完整性，在分切時一定充分考慮下刀位置，分切位置錯誤，會導致拉伸纏繞膜蹤跡困難或圖案缺少。為保證纏繞膜分切質量，希望在生產過程中注意上述4大問題。

Slitting position of Wuxi stretch winding film slitting position refers to the cutting position of the slitting knife. Any slitting machine has a certain slitting deviation. In order to ensure the integrity of the product pattern, the cutting position must be fully considered during slitting. The wrong slitting position will lead to the difficulty of stretching and winding film trace or the lack of pattern. In order to ensure the slitting quality of winding film, we hope to pay attention to the above four problems in the production process.
