怎麽選擇手用纏繞膜？

作者：閱讀量：发布日期：2021/7/8 14:21:18

信息摘要：

首先，如果手卷繞膜很厚，拉拔時會很難拉拔，尤其是手PE卷繞膜。如果手卷繞薄膜沒有完全拉伸，則不能充分反映其收卷性能。這樣一來，我們不僅浪費了材料，而且産品無法包裝，這是一種浪費。

其次是缠绕膜的粘性，粘性越高越好，这样才能起到防雨防尘作用，而且包装好的产品在经过长途运输过程中才不会被风吹的膜尾乱飞，很不美观。因而市面上，比较常规的手用PE缠绕膜是2丝即0.02mm厚度，再次是纏繞膜的使用成本問題，目前，隨著現代流延膜技術的發展，纏繞膜的厚度可以做到越來越薄，強度也越來越好，拉伸性及抗刺穿性也有了很大的提高，但是因爲很多客戶並不太了解，還延續之前的慣性，還是擔心纏繞膜做薄後強度會不會隨之降低，不敢嘗試使用超博纏繞膜，下面我就把超博手用纏繞膜的優勢給大家講一講：

1.目前手用缠绕膜较薄可以做到7微米，依次是9微米，10微米，11微米，12微米，14微米，17微米，20微米不等，手用缠绕膜越薄原料机生产成本就越高，因为缠绕膜在变薄的同时其拉伸性能不能随之降低，所以需要更高的技术及更优的配方，而且需要更先进的缠绕膜生产设备，并不是所有的设备都能生产超薄缠绕膜，只有更高端的缠绕膜生产设备才能生产出更薄更优质的缠绕膜。

2.超薄手用缠绕膜其实就是機用纏繞膜的生产配方，它的拉伸力，回缩了都跟普通手用缠绕膜的性能相当甚至优于普通手用缠绕膜，单价也就相对较高，但是它同样公斤数的缠绕膜米数确实成倍的增加，所以它的实际使用成本是大大降低的，目前很多使用者没有充分了解，只是感觉按公斤报价单价高了很多，所以觉得不划算，直接就否定了，实际上超薄手用缠绕膜按米算单价会便宜很多，因为我们实际使用缠绕膜是按米数使用的，只要能满足包装要求，缠绕膜越薄，米数就越多，包装的产品个数也就越多。

He looked out of the window, and there was that confounded figure still jigging about. It had come nearer to the ground. It hovered, with a curious air of not being related to its surroundings that was more than puzzling. It did not seem to know what it was about, but hopped along aimlessly, as though scenting a track, stopped for a moment, blundered forward again and made a zig-zag course towards the ground. The doctor watched it advancing[Pg 6] through the broad meadow that bounded the pitch, threading its way between the little groups of grazing cows, that raised their heads with more than their ordinary, slow persistency, as though startled by some noise. The figure seemed to be aiming for the barrier of hurdles that surrounded the pitch, but whether its desire was for cricket or merely to reach some kind of goal, whether it sought recreation or a mere pause from its restless convulsions, it was difficult to tell. Finally, it fell against the fence and hung there, two hands crooked over the hurdle and its legs drawn together at the knees. It became suddenly very still—so still that it was hard to believe that it had ever moved. Hetty looked up shyly. There was a faint little smile on her face. She wore a single stone diamond heart on her breast. But for this Bruce would not have known how quickly she was breathing. Steam-engines. "Why not, sir?" I asked. Maybe it isn't polite to criticize people you've been visiting? [5] In saying that the post-Aristotelian philosophers were not original thinkers, we must guard against the supposition that they contributed nothing of value to thought. On the contrary, while not putting forward any new theories, they generalised some of the principles borrowed from their predecessors, worked out others in minute detail, and stated the arguments on both sides of every controverted point with superior dialectic precision. Thus, while materialism had been assumed as self-evidently true by the pre-Socratic schools, it was maintained by the Stoics and Epicureans on what seemed to be grounds of experience and reason. And, similarly, we find that Plotinus, having arrived at the consciousness that spiritualism is the common ground on which294 Plato and Aristotle stand, the connecting trait which most completely distinguishes them from their successors, proceeds in his second essay436 to argue the case against materialism more powerfully than it had ever been argued before, and with nearly as much effect as it has ever been argued since. [62] THE Surgeon, who had conceived quite a good opinion of the Deacon's ability, readily certified that the boys could be safely taken home, since they would have the benefit of his care and attention, and the necessary papers came down from Headquarters that day. The Deacon had the good luck to find his old friend, the Herd-Boss, who took a deep interest in the matter. He offered to have as good a team as he had at the crib the next morning, with the wagon-bed filled with cedar-boughs, to make as easy a couch as possible for the rough ride over the mountains. Never mind us, never mind AMP, never mind the metals we need. HoME 女洗澡一件也不穿 ENTER NUMBET 0010www.0715city.com.cn
