Today, due to the progress in the industrial market, glass containers for food are bargaining for in comparison with plastic containers. Even in spite of a rather low level of savings in the quality of goods, plastic remains more profitable from an economic point of view. As for glass, this material has a less negative effect on the nutritional composition of the product and, moreover, increases the shelf life. So what exactly is glass technology and what are the requirements for its manufacturer?
The main percentage of the chemical composition is SiO2, or in simple words, sand. Its amount reaches 70 percent and even more. But of course, one must take into account the fact that products in glass containers are constantly endangered due to possible mechanical damage during the transportation of goods from the place of manufacture to the point of sale. To do this, use such chemicals that can provide the container with strength and protect it from external factors. These substances are MgO and Al2O3. Their number in the composition is exactly all a few percent, but the task they perform is very important for the quality of glass containers.
To increase the strength of the container, they are amenable to thermochemical treatment, the essence of which lies in the use of ultra-high temperatures. Achieving the desired result is important, since even minor defects can cause serious problems associated with the users themselves. Invisible damage due to oversight can allow a product to end up on store shelves. But due to the violation of the tightness, it becomes open and easily accessible to bacteria from the external environment, becoming a threat to the health of buyers. For this reason, glass technology requires careful monitoring.
