Original weave density tolerance is the ratio of a given standard weave density or reduce the number of multiple flat yarn. 2. The quality of woven fabric per unit area. Woven square meter basis weight is expressed as the number of grams of weight, it is woven an important technical indicators. Weight per square meter depending on the number of warp and weft density and thickness of the flat yarn color woven bags of rice, weight per square meter tensile strength woven affect the number of load capacity, weight per square meter number of production companies to control costs as a major link. Use in the design of container bags, we should give full consideration to customers FIBC specific ways and means, such as Lifting, transport, loading material properties. Also consider whether the food packaging, to consider the package of food, non-toxic, harmless. The tightness of packaging materials is different, different sealing requirements. The powder or toxic substances, contaminated items afraid sealing performance requirements are very strict, easy to damp or moldy materials for tightness also have special requirements. So in the design of container bags, note considering fabric coating process and the sewing process to close Xiong Yu Xin plastic packaging plant Biansi process include: raw materials modification, blending color bags manufacturer, color, fill color bags , preparation, anti-aging, anti-degradation problem, the extrusion process temperature, pressure, flow regulator traction control than the rheological behavior and extrusion process, power, yield issues, the drafting process, the blow-up ratio, drawing ratio, crystal cooling, orientation, heat treatment stereotypes, the process of forming and winding spindles quality testing and other technical issues, mainly used for packaging textiles, knitting cotton goods, clothing, shirts, etc. (4) PVC plastic bag Purpose:.. A gift bags; B. luggage bags, knitting cotton goods bags, cosmetic bags; C. (zipper) paper bags, polyethylene bags color bags Shijiazhuang odorless, non-toxic, feel like wax, It has excellent low temperature properties, good chemical stability, resistance to most acid-base erosion, room temperature, soluble in common solvents, water absorption, excellent electrical insulation properties; but polyethylene for environmental stress is very sensitive, heat aging poor polyethylene due to the nature of different varieties, depending on the molecular structure and density of color bags rice bags |. Xin Yu Package (certified) | Printing woven by Xiong Yu Xin plastic packaging plant.
