Compared to other packaging materials, glass packaging containers have the following advantages in packaging: firstly, glass containers have good corrosion resistance and acid resistance, suitable for packaging acidic substances; Secondly, glass does not undergo any changes in material properties when in contact with most chemicals, and does not contaminate the packaged food; The third is the good barrier and sealing effect of glass packaging containers, which can increase the shelf life of food; Fourthly, glass packaging materials have high transparency and strong plasticity, and can be processed into various shapes according to different needs. Based on the above characteristics and advantages, glass packaging containers have a wide range of applications and good market demand in packaging and storage of various alcoholic beverages, food seasonings, chemical reagents, and other daily necessities. The production of glass packaging containers is also constantly increasing. The overall production of glass packaging containers in China has maintained continuous growth,
The survival and development of the glass container industry directly affect people's daily lives and the development of related supporting industries. The main raw materials for glass containers are quartz sand, soda ash, and broken glass, and the main energy sources are electricity, coal, etc. Glass packaging containers are a traditional industry in the national economy with a long history. Among them, quartz sand and soda ash are the basic raw materials for chemical reactions to form glass; Crushed glass is directly added to the kiln after cleaning, and is physically melted to form glass liquid, which is then reused to make glass packaging containers; According to the different ways of providing power, kilns can be divided into electric kilns and coal kilns. The upstream raw materials and energy have a direct impact on the product quality and production cost of glass packaging containers. Currently, the upstream industries such as quartz sand and soda ash have sufficient supply capacity to meet the normal production needs of the glass container industry.
Industry analysts said that the demand of downstream industries for glass container products directly determines their production and sales. For example, beer consumption has seasonal slack and peak seasons, and the demand elasticity of Baijiu market is also large, so the demand for liquor and beverage bottles is seasonal; The peak season for the production of bottled food often occurs during the mature season of the food, and the corresponding demand for bottled bottles will also show seasonal growth. In addition, downstream industry customer demand has rigid characteristics, so glass packaging containers do not have obvious cyclical features. Glass packaging containers have a wide range of applications and good market demand in the packaging and storage of various types of alcoholic beverages, food seasonings, chemical reagents, and other daily necessities due to their chemical stability, resistance to compression, and good barrier sealing properties.
