In order to compete with new packaging materials and containers such as paper products containers and plastic bottles, the glass packaging industry in developed countries has been working hard to make the products more reliable, more beautiful in appearance, lower in cost and cheaper in price. In order to achieve these goals, the development trend of foreign glass packaging industry is mainly reflected in the following aspects:
Adopt advanced energy-saving technology
Save energy, improve melting quality and extend furnace life. Another way to save energy is to increase the amount of broken glass. The amount of broken glass in foreign countries is 60%-70%. Ideally, 100% cullet is used to achieve the goal of “ecological” glass production.
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 common method adopted by developed countries is to use multi-group and multi-drop forming machines.
