Glass bottle packaging has rebounded faster in recent years. There are many glass bottles and jars that are considered to be glass bottles that may replace plastic bottles. In fact, this idea is wrong. In the past few years, glass bottles have not changed substantially in terms of production technology or design concepts.
The main reason for this is that there are frequent safety incidents in plastic bottle packaging, and people are worried about the safety of plastic bottle packaging materials and cannot find a better alternative. Glass bottles have become the choice.
1. Transparency. The glass is transparent, from which the medicine liquid or the change of medicine can be seen by eyes. The status of liquid within the package can be observed without the assistance of any instrumentso it can be used to to judge the change of colors, foreign matters and the volume, being easy to have fundamental diagnosis whether the liquid goes bad and further ensuring the safety of the liquid.
2. Air impermeability. The glass is closed, being airtight and impermeable, which is important to corrosion resistance. In addition, it is stainless corrosion and it has no aging and no deterioration; at the same time, its sealing air impermeability will not weaken, which extremely benefits the long-term storage of liquid. It is able to be disinfected at a high temperature because the glass can resist 121 degrees or even higher, with no transformation and no significant change in other properties. It has no composition or volatile matter on its own. It can be used at 450 degrees in a short time and 350 degrees for a long time, nearly enduring whatever high temperature and its follow-up processing treatment.
3. Good chemical stability.The organic chemical reliability of the glass container is good, not easy to react with the sealed container materials except for alkali, hot phosphoric acid and hydrofluoric acid. It has good clarity, and can add iron, cobalt, chromium and other additives in the raw materials to produce a variety of colors of glass bottles (such as tiger glass, environmental glass, pale glass, cobalt blue glass, milk white glass, opalescent glass). It has good temperature resistance and great tensile strengthand, not easy to deformation and resistant to internal pressure. With high relative density and a sense of net weight, it is suitable for more high-end packaging. With good barrier and sanitary and storing properties, it is easy to seal, and can be sealed tightly again after opening. Thus glass containers are commonly used in high-ends or some skin care packaging.
4. Rich in raw materials. The composition of glass is similar to that of the Earth. All components of glass come from the known minerals of the Earth.
5. Being recycled. It can be recycled and goes on reproduction at a high temperature, which is able to provide raw materials continuously and be reused.
