The Development Trends of Foreign Glass Packaging Industry

In order to compete with new packaging materials and containers such as paper containers and plastic bottles, glass packaging industry in developed countries has been committed to making product quality more reliable, appearance more attractive, cost lower, and price lower.

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

　　Adopting advanced energy-saving technologies

Another way to save energy, improve melting quality, and extend the kiln to save energy is to increase the amount of broken glass used. The amount of broken glass added in foreign countries reaches 60-70%. The most ideal is to use 100% broken glass to achieve the goal of "ecological" glass production.

　　Lightweight bottle and can　　

In developed countries such as Europe, America, and Japan, lightweight bottles have become the dominant product of glass bottles and cans.

80% of the glass bottles and jars 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 (NNPB), cold and hot end spraying of bottles and cans, online detection and other advanced technologies are the fundamental guarantees for achieving lightweight bottles and cans. Some countries are developing new surface reinforcement technologies for bottles and cans in an attempt to further reduce their weight.

　　Improve labor productivity　　

The key to improving the labor productivity of glass bottle manufacturing is how to increase the molding speed of glass bottles. The current common approach adopted by developed countries is to use multi group and multi drop forming machines. The large kiln that matches the high-speed molding machine must have the ability to provide a large amount of stable high-quality glass liquid, and the temperature and viscosity of the material droplets must meet the requirements of the optimal molding conditions.

For this reason, the raw material composition must be very stable, and the refined standardized raw materials used by glass bottle production enterprises in developed countries are mostly provided by specialized raw material production enterprises. The thermal parameters of the kiln to ensure melting quality should be controlled using a digital control system to achieve optimal control throughout the entire process.

　　Improve production concentration

In order to adapt to the severe competitive situation caused by the challenges of other new packaging products in the glass packaging industry, a large number of glass packaging production enterprises have begun to merge and reorganize, improve the concentration of the glass container industry, optimize resource allocation, improve economies of scale, reduce disorderly competition, and enhance development capabilities. This has become the current trend in the world's glass packaging industry.
