Bio-Degradable Paper-Yarn Bag(Cement Bags)

Introduction of the Bio-degradable paper-yarn bags:
Bio-degradable paper-yarn bag is the latest type packaging bag with 6 features, which are: Lower Broken Rate & Strong Intensity, Dampproof & Breath Freely, High Aging Resistance, High-Temperature Resistance, Stack without slipping, Environmental Protection and Recyclable.  The paper-yarn bags 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, The paper yarn bags are widely applied to pack building materials, chemicals, minerals, agricultural sideline native products, food, feed, forage and seeds.

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" ***0 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 fiber cover the micropores with negative pressure.  The moisture cannot get into the bag.  So it effectively solves the contradictory problem and protects cement quality.
