Compared with other packaging materials, glass packaging containers have the following advantages in packaging: First, the material properties of glass will not change in contact with most chemicals, and there will be no packaging pollution to the packaged food; second, Glass containers have good corrosion resistance and acid corrosion resistance, and are suitable for the packaging of acidic substances; third, glass packaging containers have good barrier properties and sealing effects, which can increase the shelf life of food; fourth, glass packaging has a high degree of transparency. At the same time, it has strong plasticity and can be processed into various shapes according to different needs. Based on the above features and advantages, glass packaging containers have a wide range of applications and good market demand in the packaging and storage of various beverages, food seasonings, chemical reagents and other daily necessities, and the output of glass packaging containers is also increasing. The “2017-2021 In-depth Market Research and Investment Strategy Suggestion Report on the Glass Container Industry” released by Xinsijie shows that the overall output of glass packaging containers in my country has maintained continuous growth. The cumulative annual output of glass packaging containers in my country from 2014 to 2016 was 19.75 million tons. , 20.47 million tons and 22.08 million tons.

Glass packaging containers are a traditional industry of the national economy and have a long history. The survival and development of the glass container industry directly affects people’s daily life and the development of related supporting industries. The main raw materials of glass containers are quartz sand, soda ash and broken glass, etc., and the energy is mainly electricity, coal, etc. Among them, quartz sand and soda ash are the basic raw materials for chemical reaction to form glass; broken 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; Furnaces can be divided into electric kilns, coal kilns, and kilns. Upstream raw materials and energy have a direct impact on the product quality and production cost of glass packaging containers. At present, upstream quartz sand, soda ash and other industries have sufficient supply capacity to meet the normal production needs of the glass container industry.

Due to the advantages of stable chemical properties, extrusion resistance, and good barrier sealing, glass packaging containers have a wide range of applications and good market demand in the packaging and storage of various types of beverages, food seasonings, chemical reagents and other daily necessities. Industry analysts said that the downstream industry’s demand for glass container products directly determines its production and sales. For example, beer consumption has a seasonal low and peak season, and the consumption demand of the liquor market is also more elastic, so the demand for wine and beverage bottles is seasonal; The production season of canned food is often in the mature season of the food, and the corresponding demand for canned bottles will also show a seasonal increase. In addition, customer demand in downstream industries has rigid characteristics, so glass packaging containers do not have obvious periodic characteristics.
