Glass bottles and jars have a series of advantages, such as cleanliness, beauty, transparency, high chemical stability, airtightness, easy sealing, keeping the properties of the contents unchanged, and can be used repeatedly for many times, abundant raw materials, and cheap prices. They are used extensively as packaging materials by the food, pharmaceuticals and chemical industry. Glass bottles and jars have been subject to strong competition from plastic bottles etc., which has forced it to continuously improve its production process to obtain large quantities of low-cost and high-quality products. At present, glass bottles and jars have reached a fully automated level from the production process of raw material batching, melting, forming, annealing, product inspection, and packaging.
The main disadvantages of glass bottles and jars are their low mechanical strength, their fragility and the weight of the unit. Due to the improvement of modeling design, strict control of the production process and the use of various enhancement measures (pointing to the solution to the problem), foreign countries have achieved more light weighting of primary bottles that are not recycled, and the above two disadvantages have gradually improved.
