mitted to making their products more reliable, more beautiful, lower cost, and cheaper. In order to achieve these goals, the development trend of foreign glass packaging industry is mainly manifested in the following aspects:

　　First, adopt advanced energy-saving technology. One 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 can reach 60%-70%. The most ideal is to use 100% broken glass to achieve the goal of "ecological" glass production.

　　Secondly, the bottle and can are lightweight. In developed countries such as Europe, America and Japan, lightweight bottles have become the leading products of glass bottle manufacturers. 80% of the glass bottles produced by Obedand in Germany are lightweight disposable bottles. The precise control of raw material composition, precise control of the entire melting process, small-mouth pressure blowing technology, spraying of the cold and hot ends of the bottle and can, on-line inspection and other advanced technologies are the fundamental guarantee for the realization of the lightweight of the bottle and can. Jiangsu glass bottle manufacturers are developing surface enhancement technology for bottles and cans, trying to further reduce the weight of bottles and cans, and connect with the world at the fastest speed!

　　 Third, increase labor productivity. The key to improving the labor productivity of glass bottle manufacturing is how to increase the molding speed of glass bottles. At present, the commonly adopted method in developed countries is to choose a molding machine with multiple groups and multiple drops. Large kilns matched with high-speed forming machines must have the ability to supply a large amount of high-quality molten glass stably, and the temperature and viscosity of the gobs must meet the requirements of the best forming conditions. 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 kiln to ensure the quality of the melting should adopt a digital control system to achieve the optimal control of the entire process.

　　 Fourth, increase production concentration. In order for the glass packaging industry to face the severe competition caused by the challenges of other packaging products, 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 the allocation of resources, increase economies of scale, reduce disorderly competition, and enhance development Ability, this has become the current trend of the world's glass bottle packaging industry.
