At present, “white pollution” has increasingly become a social issue of general concern to countries all over the world. One or two things can be seen from my country’s increasingly high-pressure control of environmental protection. Under the severe survival challenge of air pollution, the country has focused its development perspective on the green economy. Enterprises also pay more attention to the development and promotion of green products. The market demand and social responsibility together gave birth to a batch of responsible enterprises pursuing green production methods.
Glass adapts to the requirements of glass packaging marketization and greening. It is called a new type of packaging material due to its environmental protection, good airtightness, high temperature resistance, and easy sterilization, and it occupies a certain share in the market. On the other hand, with the increase of residents’ awareness of environmental protection and resource conservation, glass packaging containers have gradually become government-encouraged packaging materials, and consumers’ recognition of glass packaging containers has also continued to increase.
The so-called glass packaging container, as the name implies, is a transparent container made of molten glass frit by blowing and molding. Compared with traditional packaging, it has the advantages of less material property changes, good corrosion and acid corrosion resistance, good barrier properties and sealing effect, and can be reproduced in the oven. Therefore, it is widely used in beverages, pharmaceuticals and other fields. In recent years, although the demand for glass packaging containers in the international market has shown a downward trend, glass packaging containers are still growing rapidly in packaging and storage of various types of alcohol, food seasonings, chemical reagents, and other daily necessities.
At the national level, as the “supply-side structural reforms” and “environmental protection rectification battles” continue to advance and industry access is becoming stricter, my country has introduced a daily-use glass industry access policy to regulate the production, operation and investment behavior of the daily-use glass industry. Promote energy-saving, emission-reduction and clean production, and guide the development of the daily-use glass industry to a resource-saving and environment-friendly industry.
At the market level, in order to adapt to the fierce competition in the international packaging market, some foreign glass packaging container manufacturers and scientific research departments continue to introduce new equipment and adopt new technologies, which has made a lot of progress in the manufacture of glass packaging containers. The overall output of glass packaging containers maintained continuous growth. According to statistics from Qianzhan.com, with the growth of consumption of various alcoholic beverages, it is expected that the output in 2018 will rise to 19,703,400 tons.
Objectively speaking, the overall scale of the glass packaging container manufacturing industry continues to grow, and the national glass packaging container production capacity is rapidly increasing. It should be noted that glass packaging containers also have some shortcomings, and easy to break is one of the shortcomings. Therefore, the impact resistance index of glass bottles and cans has become an important test item. Under certain conditions of ensuring the strength of the glass packaging, reducing the weight-to-volume ratio of the glass bottle is aimed at improving its greenness and economy. At the same time, attention should also be paid to the lightweight of glass packaging.
Glass bottle packaging quickly occupied part of the market with a series of physical and chemical properties such as chemical stability, air tightness, smoothness and transparency, high temperature resistance, and easy disinfection of glass packaging. In the future, glass packaging containers are bound to have broader development prospects.
