In the glass 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, 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, the use of advanced energy-saving technologies to save energy, improve melting quality, and extend the furnace to save energy is to increase the amount of cullet, and the amount of cullet from foreign countries can reach 60% to 70%. The most ideal is to use 100% broken glass to achieve the goal of ecological glass production.
Second, lightweight bottles and cans 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 German companies are lightweight disposable bottles. Advanced technologies such as precise control of the composition of ceramic raw materials, precise control of the entire melting process, small mouth pressure blowing technology (NNPB), spraying of the cold and hot ends of the bottle and can, and online inspection are the fundamental guarantee for the realization of the lightweight of the bottle and can. Jiangsu glass bottle manufacturers are developing new 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, the key to improving labor productivity in 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 forming 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 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 the concentration of production. In order to adapt to the severe competition 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 the allocation of resources and increase the scale. Benefits, reducing disorderly competition, and enhancing development capabilities have become the current trend of the world’s glass bottle packaging industry.
At present, the domestic glass industry is facing various tests. It is hoped that large domestic enterprises can learn from foreign management methods and technologies, so that Chinese glass bottles will be everlasting and full of vitality abroad!
Many times, we see a glass bottle simply as a packaging container. However, the field of glass bottle packaging is very wide, such as beverages, food, cosmetics, and medicine. In fact, while the glass bottle is responsible for packaging, it also plays a role in other functions.
Let’s talk about the role of glass bottles in wine packaging. We all know that almost all wine is packaged in glass bottles, and the color is dark. In fact, dark wine glass bottles can play a role in protecting the quality of the wine, avoiding the deterioration of the wine due to light, and protecting the wine for better storage. Let’s talk about essential oil glass bottles. In fact, essential oils are easy to use and have very strict requirements for light. Therefore, essential oil glass bottles should protect essential oils from being volatile.
Then, glass bottles should also do more in the fields of food and medicine. For example, food needs to be preserved. How to further enhance the shelf life of food through glass bottle packaging is very necessary.
At the Second Council of the Seventh Session of the China Daily Glass Association, a set of data was sorted out: In 2014, the output of daily glass products and glass packaging containers reached 27,998,600 tons, an increase of 40.47% over 2010, an average annual increase of 8 .86%.
According to Meng Lingyan, chairman of the China Daily Glass Association, in recent years, the growth trend of glass beverage bottles has been positive, especially for Beijing’s Arctic Ocean soda, whose output has tripled and is in short supply. Its demand for high-quality glass packaging containers has also increased. It has been increasing, and so has Shanhaiguan soda in Tianjin and Bingfeng soda in Xi’an. This also means that with the popularization of the basic characteristics and culture of daily-use glass, consumers have become more and more aware of glass as the safest packaging material for food, especially glass beverage bottles, mineral water bottles, grain and oil bottles, and storage containers. The market for cans, fresh milk, yogurt bottles, glass tableware, tea sets, and drinking utensils is huge.
Zhao Yali, chairman of the China Beverage Association, also admitted that almost 20 years ago, the beverages were almost all in glass bottles, but now many local time-honored beverage brands have upgraded and the market has recovered, but they still insist on using glass packaging, and some high-end mineral waters also choose to use glass bottles. , And even some of the plastic packaging used in beverages is similar in design to glass bottles. This phenomenon shows that people’s consumer psychology is more inclined to glass packaging, thinking that it is more high-end.
Meng Lingyan said that daily-use glass products are rich in variety and versatile, with good and reliable chemical stability and barrier properties. They can directly contain objects and have no pollution to the contents. They are recyclable, recyclable and non-polluting products. It is a safe, green and environmentally-friendly packaging material recognized by all countries, and it is also a favorite item in people’s daily life. During the “Thirteenth Five-Year Plan” period, with the improvement of people’s living standards and quality of life, the development of wine, food, beverages, medicine and other industries has demanded glass packaging bottles and cans, and people’s demand for various glassware, glass crafts, etc. The demand for glass art will grow steadily.
It is precisely because of this that during the 13th Five-Year Plan period, the development goal of the daily glass industry is: daily glass products and glass packaging containers of daily glass manufacturers above designated size increase by 3%-5% annually, and daily glass by 2020 The output of products and glass packaging containers will reach about 32-35 million tons.
Today, the entire packaging industry is in the stage of transformation and upgrading. As one of the market segments, the transformation of the glass packaging industry is also imminent. Although in the face of the general trend of environmental protection, paper packaging is more popular and has a certain impact on glass packaging, but glass packaging still has broad room for development. To occupy a place in the future market, glass packaging still needs to be lightweight and environmentally friendly.
