Compared with other packaging, glass packaging containers have the following advantages in packaging: first, the contact between glass and most chemicals will not change the properties of materials, and the packaging food will not be contaminated; Second, the glass container has good corrosion resistance and acid corrosion resistance, which is suitable for the packaging of acidic substances; third, the glass packaging container has good barrier and sealing effect, which can effectively increase the shelf life of food. Fourth, the glass packaging has a high degree of transparency and plasticity, can be processed according to different needs into a variety of delicate shapes. Based on the above characteristics and advantages, glass packaging containers have a wide range of applications and good market demand in various kinds of wine, food seasoning, chemical reagents and other daily necessities, and the output of glass packaging containers is also increasing. The report issued by Xinsijie on the deep market research and investment strategy of glass container industry in 2017-2021 shows that the overall output of glass packaging containers in China has maintained a continuous growth. The cumulative annual output of glass packaging containers in China from 2014 to 2016 is 19.75 million tons, 20.47 million tons and 22.08 million tons respectively.
Glass packaging container is the traditional industry of national economy, has a long history. The survival and development of glass container industry directly affect people's daily life and the development of related industries. The main raw materials for glass containers are quartz sand, soda and broken glass, and energy mainly for electricity, coal or natural gas. Among them, quartz sand and soda are the basic raw materials of chemical reaction to form glass, broken glass is added directly to kiln after cleaning, and then used to make glass packaging container through physical melting. According to the way of providing power, kiln can be divided into electric kiln, coal kiln and natural gas kiln. Upstream raw materials and energy have a direct impact on the product quality and production cost of glass packaging containers. At present, upstream quartzite sand, soda and other industries have sufficient supply capacity to meet the normal production demand of glass container industry.
Glass packaging containers have the advantages of stable chemical properties, good resistance to extrusion, good barrier and sealing, and are used in all kinds of wine and food seasoning. The packaging and storage of chemical reagents and other commodities have wide application and good market demand. Industry analysts say the downstream demand for glass containers directly determines their production and sales. For example, beer consumption has a seasonal peak season, and the liquor market has greater elasticity of demand. As a result, the demand for drinking bottles has a certain seasonality; The production season of filling food is usually in the mature season of food, and the demand for filling bottles will also increase seasonally. Moreover, the downstream industry customer demand has the rigidity characteristic, therefore the glass packing container does not have the obvious periodicity characteristic.
