Explore the development trend of foreign glass bottle technology

Glass bottle packaging industry In order to compete with new packaging materials and containers such as paper containers and plastic bottles, glass bottle manufacturers in developed countries have been committed to making the product quality more reliable, more beautiful in appearance, lower cost, and selling price Cheaper.

　　 In order to achieve these goals, the development trend of the foreign glass packaging industry is mainly reflected in the following aspects:

　　 Improve labor productivity

　　Improve cosmetic glass bottles'>The key to the labor productivity of glass bottle manufacturing is how to increase the molding speed of glass bottles. At present, the method generally adopted by developed countries is to choose a molding machine with multiple groups and multiple drops. Large-scale kilns matched with high-speed molding machines must have the ability to supply a large amount of high-quality glass liquid stably, and the temperature and viscosity of the gobs must meet the requirements of the best molding conditions.

　　 adopts advanced energy-saving technology

　　 Another way to save energy, improve the melting quality, and extend the furnace to save energy is to increase the amount of cullet, and the amount of cullet in foreign countries reaches %—%. The most ideal is to use% broken glass to achieve the goal of u0026#;ecologicalu0026#; glass.

　　 Increase production concentration

　　 In order to adapt to the severe competition situation caused by the challenges of other new packaging products in the glass packaging industry, a large number of glass packaging manufacturers have begun to merge and reorganize to increase the concentration of the glass container industry in order to optimize resource allocation, increase economies of scale and reduce Orderly competition and enhanced development capabilities have become the current trend of the world's glass packaging industry.

　　Glass bottles and jars produced by Obedand, Germany,% are lightweight disposable bottles. Precise control of raw material composition, precise control of the entire melting process, small mouth pressure blowing technology (NNPB), spraying of hot and cold ends of bottles and cans, online inspection and other advanced technologies are the fundamental guarantee for achieving lightweight bottles and cans. Some countries are developing new surface enhancement technologies for bottles and cans in an attempt to further reduce the weight of bottles and cans.

　　 For this reason, the composition of raw materials must be very stable. Most of the refined standardized raw materials used by glass bottle manufacturers in developed countries are provided by specialized raw material manufacturers. The thermal parameters of the furnace to ensure the quality of the melting should adopt a digital control system to achieve optimal control of the entire process.
