Cement Bags

Bio-degradable Paper Yarn Bag is the latest type packaging bag made by the latest new process of weft surrounding continuously, without centre joint. Generally, complex packing bags/bags consist of 2-layer of national standard kraft paper inside and outside, between which is a glued film formed by vinylon water-soluble yarn and PVA, thus combined three into one. Without condensations aldehyde treatment,vinyoln water-soluble yarn can be dissolved in 80℃ water, so the usedbags can be recycled, without any pollution to environment after going through hydrolysis. In addition, the bags have good features of Lower broken rate & High intensity, Proof moisture and air permeability, High aging resistance, High-temperature resistance, Stack without slipping, Environmental protection and be recyclableThe products have been sampled and tested by Chinese authoritative State Products Quality Control Department (CQC), all technical properties are up to or exceed the latest national standard, have solved the problem that is very difficult to overcome, which existed in heavy packing industry for a long time. Therefore, it is widelypromoted and used by the State and is the green packaging bag accorded with International Environmental Demand. It is exported to America, Japan, Europe, Australia and other countries.Application in cement packing industry:Using pressure filling method, cement is quickly loaded into the bag. Cement package exist a contradictory problem of exhaust and moistureproof, which the traditional cement bags cannot solve. Our company develops "Micropores Technology” 5000 micropores per square meter in bag surface. The micropores let the air get out of bag easily. At the time of filling, cement grain and the wool fibercover the micropores with negative pressure. The moisture cannot get into the bag. So it effectively solves the contradictory problem and protects cement quality. As the special factory, Shandong province of Shanxi Yangquan Zaozhuang Cement Concrete is exported by using paper compound bag, use gauze effect is good.
