According to the second batch of national standard system in 2012 to amend the requirements of the notice, the National Standardization Technical Committee project, by the Shaanxi Kelon Plastic Industry commitment to "polyethylene horizontal blow molding tank" industry standard drafting work. In September 2014, the China Packaging Association executive secretary, the national packaging industry standards group leader Wang Li held in Xi'an, held and adopted the "polyethylene horizontal blow molding tank" industry standard review. China Plastics Packaging Committee of experts and the market upstream and downstream enterprises and users to participate in the standard review and discussion work, agreed that the implementation of the standard on the current market, product quality confusion, disorderly production of the situation has a normative guidance for hollow Packaging industry and the legitimate rights and interests of consumers protection is of great significance. 3. Large plastic hollow container development prospects Polyethylene horizontal blow tank is only a large plastic hollow container of a species, but its extensive market application situation is sufficient to show that large containers have great potential for development. With the continuous development of the national economy, the continuous expansion of market demand and the domestic plastic hollow industry technology continues to progress, large plastic hollow containers are moving in the fine, functional direction, I believe the future in the industry, agriculture, transport packaging, Daily production and life and other aspects must be widely used. Conclusion Large plastic hollow containers huge market development potential must have to adapt to the advanced blow molding technology support, but the technical progress is the equipment manufacturers, manufacturers, market supply and demand,
????Raw materials, precision machining and other factors together, the results of any one part of the technology will lead to its development stagnation, empathy, a single factor can not let it leaps and bounds rapid development, therefore, to strengthen the entire industry chain technology exchanges, Mutual help and common progress is to promote its healthy and sustainable development of the feasible way.

1. How do plastic containers be classified? Plastic can be plastic polymer material abbreviation. Thermoplastics: After molding can be re-formed by heating and / or pressurization. Thermosetting plastics: can not be molded by heating or / and pressure after molding. Rigid plastic containers are plastic containers with a certain shape, good stiffness and greater strength and surface hardness. Flexible plastic containers: refers to the plastic film or film formed by the packaging, that is, flexible packaging. According to the external shape
