Technological changes in craft wine bottles In daily life, medicinal glass bottles can be seen everywhere. Whether it is beverages, medicines, cosmetics, etc., medicinal glass bottles are their good partners. These glass packaging containers have always been considered a good packaging material because of their transparent beauty, good chemical stability, no pollution to the contents, can be heated at high temperatures, and old bottles can be recycled and reused. Despite this, in order to compete with packaging materials such as metal cans and plastic bottles, pharmaceutical glass bottles are constantly improving their production technology to make products with good quality, beautiful appearance and low cost. After the construction technology of regenerative glass furnaces, glass melting technology has ushered in the second revolution, which is oxy-combustion technology. In the past ten years, the practice of various countries in transforming this technology on glass melting furnaces has shown that oxy-combustion technology has significant advantages such as low investment, low energy consumption, and low pollutant emissions. In the United States and Europe, lightweight bottles and cans have become the leading products for glass bottles and cans. Small-mouth pressure blowing technology (NNPB) and hot and cold end spraying technology for bottles and cans are all lightweight production technologies. A German company has been able to produce a 1-liter concentrated juice bottle that weighs only 295 grams. The surface of the bottle wall is coated with organic resin, which can increase the pressure strength of the bottle by 20%. In a modern factory, producing glass bottles is no easy task, and there are scientific problems to solve.
