[Chinese Packaging Network News] For domestic glass bottle manufacturers, it can be said to be a bitter experience, and now the market's demand for glass bottles has allowed the market that has been suppressed by plastic bottles to be released. However, there are many emerging packaging materials on the market. This is also a challenge for glass manufacturers. Glass packaging industry In order to compete with new packaging materials and containers such as paper product containers and plastic bottles, glass bottle manufacturers in developed countries have been devoting themselves to making product quality more reliable, aesthetically pleasing, cheaper, and cheaper.
First of all, glass bottle manufacturers need to speed up restructuring and change the current disorderly competition. We all know that there are still many small and medium-sized glass bottle manufacturers in China. The homogenization of these glass bottle manufacturers is serious and the product is highly repetitive, resulting in excessive duplication of resources. It is imperative to speed up the concentration of glass bottle manufacturers and integrate the resources of glass bottle manufacturers. Only in this way can more rational resource optimization be configured.

Second, speed up the recycling of glass bottles, increase the amount of broken glass, improve the quality of melting, and extend the furnace to save energy. The recycling of raw materials in glass bottles is an important part of the sustainable development of the glass bottle industry.
There are still many difficulties for glass bottle manufacturers to overcome, requiring more targeted solutions from manufacturers.
In order to achieve these goals, domestic development trends are mainly manifested in the following aspects:
The first adopts advanced energy-saving technologies
Another way to save energy, improve melting quality, and extend the furnace to save energy is to increase the amount of broken glass. The amount of broken glass imported abroad reaches 60%-70%. The ideal is to use 100% broken glass to achieve the goal of "ecological" glass production.
Second bottle lightweight
In developed countries such as Europe, America and Japan, lightweight bottles are the leading products of glass bottle manufacturers. 80% of the glass bottles produced by Obedand in Germany are lightweight disposable bottles. Precise control of raw material composition, precise control of the entire process of melting, NNPB, hot and cold-side spraying of bottles and cans, on-line inspection and other advanced technologies are the fundamental guarantees for achieving lightweighting of bottles and cans. Jiangsu glass bottle manufacturers are developing new surface enhancement technology for bottles and cans, trying to further reduce the weight of bottles and cans to the world at the fastest speed!
Third, increase labor productivity
The key to improving the productivity of glass manufacturing is how to increase the molding speed of glass bottles. At present, the commonly adopted method in developed countries is the use of multi-group, multi-drop molding machines. Large-scale kilns that match high-speed molding machines must have a large capacity to stably supply high-quality glass liquids. The temperature and viscosity of the gobs must meet the requirements of the best molding conditions. For this reason, the raw material composition must be very stable, and the refined standard raw materials used by glass bottle manufacturing companies in developed countries are mostly provided by specialized raw material production enterprises. To ensure the melting quality of the furnace thermal parameters to adopt a digital control system to achieve the best control of the entire process.
Fourth, increase production concentration
In order to adapt to the severe competition situation caused by the challenge of other new packaging products in the glass packaging industry, a large number of glass packaging manufacturers have begun mergers and reorganizations to increase the concentration of the glass container industry in order to optimize resource allocation, increase economies of scale, and reduce unordered competition. Enhancing development capabilities has become the current trend of the glass packaging industry in the world.
