维纶水溶纱复合包装袋是由复合制袋机工艺技术制成的纬纱连续环绕无中缝的新型包装袋。纸纱复合包装袋其结构为内外二层国标纸袋纸，中间粘结网状维纶水溶纱，三位一体复合而成。由于维纶水溶纱未经缩醛处理能溶解于80℃左右的热水，使用过的废袋经水解后回收再生利用，不污染环境。此外，该包装袋还具有防潮、耐热、抗老化、高强度和破损率低等特性。该产品经国家产品质量监督部门抽样检测，各项指标均可达到或超过国家标准。为此，它是国家大力推广使用，并符合国际环保要求的绿色包装产品。现已大量直接或间接出口美国、日本、澳大利亚、欧洲等国家。 维纶水溶纱复合包装袋广泛适用于包装谷物、饲料、淀粉、干酪素等农副土特产品，以及水泥、碳化硅、双氰胺、石墨、炭黑、电石、橡胶、滑石粉、钛白粉等化工、矿产品的各种粉粒状物品。 COMPOSITE PACKING SACKS OF VINYLON SOLUBLE YARN Composite packing sacks of vinylon soluble yarn are newt ype packing sacks. They are made with new process of weft surrounding contiguously and non-middle-suture by the composite sack-making machine. General, comp-osite packing sack consists of 2-layers of national standard sack-making paper outside and inside, with glued net vinylon yarn in between, thus combining 3 in 1. Due to vinylon soluble yarn without condensating aldehyde treatment can dissolve into about 80℃ hot water, so the waste sack can be recycled without any pollution to the environment after going through hydrolysis. In addition to, the sacks have good features of wet proof, thermo stability ageing resistance, high strength, lower broken rate also. The products have been sampled and tested by the State Products Quality Control Department, all technical properties are up to or exceed the latest national standard. Therefore, they are widely popularized by the State and to conform to international environmental protection as green package products. The products have been exported to America, Japan, Australia, Europe and other countries. Composite packing sacks are widely applied to pack all kinds of powder and particle matters for grain, feed, starch, cheesy matter, agricultural & side line products, cement, carbon black, dicyandiamide, graphite, rubber, titanium white, chemical industry & mineral products and so on.
