For chemical products that are water-absorbent, corrosive, and easily oxidized, ordinary plastic woven bags and paper bags are far from meeting their packaging requirements. Hebei Xiongxian Xuri Packing Co., Ltd. has introduced internationally advanced equipment for this issue. At present, it has produced seven-layer and nine-layer co-extruded high-barrier packaging bags, effectively solving the problem of high barrier properties and strong corrosion resistance for some chemical product packaging requirements. .
The seven-layer and nine-layer high barrier packaging bags adopt PE/TIE/PA/EVOH/PA/TIE/PE structure. The nine-layer bags have two layers of PA (nylon) and two layers of PE (polyethylene), which have strong barrier capability. Long shelf life, resistance to pressure, high strength, resistance to stretching and other characteristics. PA has water-blocking and oxygen-barrier properties, and it has excellent puncture-resistance, tensile strength, and drop-resistance; PE has a water-blocking effect, and two-layer PE reinforces the water-blocking performance; EVOH is the best barrier material at present. First, the use of EVOH can greatly improve the oxygen and water barrier properties of the film and extend the shelf life of chemical products. According to reports, at present most chemical packaging, the use of a thickness of 7 silk ~ 12 silk seven co-extruded packaging film to meet the requirements, and the thickness of five layers must be within 15 silk to meet. Xiongxian Rising Sun Packaging Co., Ltd. has become a leading manufacturer of multi-layer co-extruded high-barrier vacuum packaging films in China. The products are exported to Europe, the United States, Canada, Japan, South Korea and other countries and regions. (Guo Haijun)
