编织袋的韧性却是决定编织袋的使用寿命的一个关键性因素。许多客户在采购编织袋的时候都会考虑，它的存放周期，却不知道原来编织袋的寿命是根据编织袋的韧性程度的呢!

      膜片的冷却成形：扁丝的强度前进了，处理了断丝的问题，编织袋的袋布的强度增强。水箱是拉丝机的一个组成局部，水箱中的冷却水温的凹凸影响膜片冷却成形后的物理功能，也是影响扁丝强度的要素。这是由于聚丙烯是结晶型高分子资料，其结晶外形有多种。在自然冷却进程中每每会组成相当大的α型球晶，这种球晶拉伸取向比拟坚苦，不利于拉丝。

 

原材料的配比：添补母料是原料配比的重要成份之一，结果是改进扁丝的物理功能和低落资本。跟着添补母料添补量的添加，扁丝的拉伸强度将逐步低落。

 

      编织袋厂家在生产过程中对编织袋的幅度设计以及手感有着严格标注要求。各种编织布幅宽直接影响制袋工序。

 

      对于筒布用折经表示幅宽，折经等于圆周长的一半。幅宽回缩率，所有编织布织造卷取后的宽度，在展卷切割，印刷，缝合后，制成袋子的宽度都要略小于卷取时的宽度，我们称幅宽回缩。扁丝窄，编织的平，手感柔软，扁丝宽，编织布时折叠丝多，手感粗糙。在塑料编织袋的手感问题上，有着不同材质的分类差别。

 

PP扁丝编织物手感较厚实，挺阔，粗硬些。HDPE扁丝编织物手感较软，润滑，不致密。在PP扁丝料中添加钙质母料，手感挺阔，PP中少加HDPE会使其柔软些。它们的韧性也是不相同的，韧性好不易破损因此使用寿命更长一些！

The toughness of woven bag is a key factor to determine the service life of woven bag. Many customers in the purchase of woven bags will be considered, it's storage cycle, but do not know the original woven bag life is based on the tenacity of the degree of it! COOLING FORMING OF DIAPHRAGM: the strength of flat wire has advanced, the problem of broken wire has been solved, the strength of woven bag cloth has been enhanced. Water tank is a part of drawing machine. The temperature of cooling water in water tank affects the physical function and the strength of flat wire. This is because polypropylene is a crystalline polymer material, its crystalline shape has a variety of. In the process of natural cooling, large-sized spherulites are often formed. The tensile orientation of this kind of spherulites is hard, which is disadvantageous to wire drawing. The proportion of raw materials: filling masterbatch is one of the important components of the proportion of raw materials, the result is to improve the physical function of flat silk and low capital. The tensile strength of the flat yarn will gradually decrease with the addition of the filling masterbatch. Weaving bag manufacturers in the production process of woven bag width design and feel have strict labeling requirements. The width of all kinds of woven cloth directly affects the bag-making process. For Cylinder Cloth, the width is indicated by the warp, which is equal to half of the circumference of the circle. Width shrinkage, the width of all woven fabric after winding, after cutting, printing, sewing, made into a bag width is slightly less than the width of the winding, we call width retraction. The flat wire is narrow, flat, soft and wide, and has a rough feel when it is folded. On the handle of plastic woven bag, there are different kinds of materials. Pp Flat Silk Fabric feel thick, quite wide, rough some. Hdpe Flat Silk Woven Fabric feels soft, lubricated, not dense. In PP flat silk material to add calcium masterbatch, feel very broad, PP less HDPE will make it soft some. Their toughness is not the same, good toughness is not easy to damage so that the service life is longer!
