信息摘要：

缠绕机的使用越来越普及，如何选择機用纏繞膜是很多采购人员想要知道和了解的问题之一，下面我们就来一起来了解一下。

機用纏繞膜的选择一般分为两个层次，第一次层次就是能用，大部分的缠绕膜人员还停第一层次，能用是较为基本的功能，因为包装的效果马马虎虎，包装相对的成本也会大一些，一般是这两个问题没有考虑到，一个是公司包装材料的浪费是很大的，考虑能用是远远不够的，我们要能够用的好，用的精，在满足包装的同时也能节约成本，这才是一个好的合格的采购员应该做的，也就是第二个层次，我们所在来看看采购需要注意一下几点：

1、單價越便宜不是越好

纏繞膜雖然是按公斤計價的，但還我們使用的時候實際是按米數使用的，如果同樣重量的一卷纏繞膜，一種能包裝50個産品，一種包裝100個産品，而且單價相差不多，那肯定是包裝個數多的産品用的便宜，而我們的采購往往忽略這一點，說白了，就是性價比的問題

2、不是越厚越好適合最重要

有些纏繞膜廠家爲了多賣一些纏繞膜，把膜做到很厚，這樣客戶的使用量就會增加，他們就會多賺一些錢，而我們有些采購員反而覺得越厚越好，這樣就會使公司造成很大的浪費

3、拉伸比例

为什么说拉伸比例是一个很重要的参数呢，因为機用纏繞膜的核心性能，高拉伸比例缠绕膜意味着更节省，跟节能，但是高拉伸比的缠绕膜必须在相同拉伸比例的预拉伸缠绕机上使用才能更能体现出其性能，因为只有充分拉伸的缠绕膜才能更节省，其拉伸回缩力才能充分体现，货物才能包装的更牢固，外观更漂亮

4、回縮力

纏繞膜的回縮力是是非常重要的技術參數，回縮力在沒有充分拉伸的情況下是體現不充分的，這樣就算是優質的纏繞膜，也體現不出其優越性，所以我們購買纏繞膜的時候一定要首先了解纏繞機的拉伸比例，兩者要匹配起來，這樣才能包裝出漂亮的産品。

根據上面的內容來看，我們在選購纏繞膜時要格外注意2點。

1.在選擇纏繞膜的時候我們選擇性價比高的纏繞膜而不是單價便宜的纏繞膜，看每米的價格而不是看公斤單價低的，這一點是大家容易忽略的一點，還有一種就是包裝相同的物品所花費的成本少就是性價比高的纏繞膜。

2、包装的牢固性非常重要，要选择能跟缠绕机相匹配的機用纏繞膜，这样缠绕膜的性能才能最好的发挥，有较大的限度利用缠绕膜的性能。

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 00106coin.com.cn
