At present, double-layer composite tank has gradually replaced the early single-layer cans to become the market leader in such products. In recent years the development and production of large-scale three-tier horizontal composite tank products in the functional, reduction, green and other advantages are more prominent, the outer layer of anti-aging, anti-ultraviolet materials, the middle of the barrier barrier materials and reinforced materials , The inner food grade raw materials, this form of container for a wider range of security better, more economical In order to meet the requirements of the market for the precise control of large container contents, Kelon Plastic Industry has made breakthroughs in the development of large-scale multi-layer composite containers with liquid level lines, which is expected to be marketed in the near future. 6.3 multi-layer composite container is the future of the hollow packaging industry is an important development trend. In recent years in the large-scale multi-layer composite container forming unit research, many domestic manufacturers have achieved fruitful results, Weifang Huayu Plastic Machinery Co., Ltd. is one of them: Huayu presses in 2012 and Kelon plastic industry successfully developed Out of the first domestic double-layer IBC liner molding unit, the 32-layer blending channel technology leading domestic, world-class. After continuous innovation, Huayu large plastic hollow container forming unit has become a large number of domestic and foreign container manufacturers focus on cooperation partners. Objectively speaking, compared with other well-known plastic machine factory similar products, we in the equipment structure optimization, equipment stability, molding process control and many other aspects need to do more exploration and research. two. From the application of polyethylene horizontal blow molding tank market to see large-scale plastic hollow container development prospects 1. Polyethylene horizontal blow tank market applications At this stage of polyethylene horizontal blow tank mainly in the central and western regions of fruit and vegetable spraying, fisheries Aquaculture, dry farming, water, facilities agriculture, tourism agriculture, biogas digesters, the annual demand of about 10 million, and the annual rate of more than 20% increase. With the introduction of multi-layer polyethylene horizontal blow molding tank products, its anti-light, anti-ultraviolet, anti-aging, anti-penetration, clean, easy loading and unloading materials, low transport costs and other fine features, has gradually to food packaging, Pharmaceutical packaging, chemical packaging and other areas of expansion, the future market development potential. 2. "polyethylene horizontal blow molding tank" industry standard development situation in April 2011 in the "China's packaging industry in the northwest development strategy seminar" by the Shaanxi Kelon Plastic Co., Ltd. for the first time to develop "polyethylene blow molding Tank "industry standard.
