Traditional medicinal glass bottles face severe market test
In our daily lives, medicinal glass bottles can be seen everywhere. Whether it is beverages, medicines, or cosmetics, medicinal glass bottles are good partners. These glass-wrapped containers are considered to be the best packaging materials due to their transparent aesthetics, good chemical stability, non-polluting contents, ability to heat at high temperatures, and recycling of used bottles. In spite of this, in order to compete with metal cans, plastic bottles and other packaging materials, medicinal glass bottles are constantly improving their production technology, so that the product quality is better, the appearance is more beautiful and the cost is lower. After the regenerative glass kiln construction technology, the glass melting technology ushered in the second revolution, which is the oxy-fuel combustion technology. In the past decade, the practice of this technology transformation in glass melting furnaces in various countries of the world has shown that oxy-fuel combustion technology has significant advantages such as low investment, low energy consumption, and low pollutant emissions. In the United States and Europe, lighter weight bottles and cans are the leading products for glass bottles and cans, and NNPB and cold and hot end spraying technologies for bottles and cans are all advanced technologies for lightweight production. German companies have been able to produce 1 liter of concentrated juice bottles, weighing only 295 grams. The wall surface of the bottle is coated with organic resin, which can increase the bottle's pressure strength by 20%. Xuzhou Hongyuan Glass Bottle Manufacturing Co., Ltd., as one of the modern professional glass bottle production plants, is clearly aware that the production of glass bottles is not an easy task and there are many scientific problems that need to be solved.
At present, a colorless, transparent, ultraviolet-absorbing UVA pharmaceutical glass bottle has emerged and attracted widespread attention.
The most prominent feature of medicinal glass bottles is their ability to clearly see the transparency of the contents. Because of this, external light can easily pass through the container, causing the content to change and deteriorate. For example, when beer is exposed to sunlight for a long time, it will produce odor and fading. Foreign experiments confirmed that when the light wavelength is 406 nm to 500 nm, the beer will fade until it stinks.
Recently, a transparent glass that absorbs ultraviolet rays has been developed abroad. It is produced by adding an ultraviolet absorbing metal oxide to the glass on the one hand. At the same time, by using the color-complementary effect, some metals or their oxides are added to discolor the colored glass.
A random sampling test of light transmittance at a wavelength of 330 nm for UVA glass and normal glass having a thickness of 3.5 mm shows that the ordinary pharmaceutical glass bottle is 60.6%, and the UVA glass is only 2.5%. Exposure to sunlight in ordinary glass bottles and UVA glass bottles also showed that the former had a much higher degree of discoloration and deterioration than the latter.
Oxo biodegradable technology can make plastic totally degradable. Plastic incorporating with TDRAâ„¢ additive, that is TDPâ„¢ plastic, will degrade in months and finally become carbon dioxide, water and bio mass particles without leaving any toxic or harmful residue. Hense, TDPâ„¢ plastic is 100% environment friendly. MST now can make kraft paper/PLA degradable bags, PLA is a 100% degradable material which we import from Italy, meantime all these material are FDA approved, suitable and safe for food packaging.
