Glass bottle is borosilicate glass replacement

Glass has high transparency, strong barrier property and other materials incomparable excellent chemical stability, and therefore made of glass packaging container in addition to the widely used in chemical industry, pharmaceutical industry, also used engine food industry. At present domestic health care food packages with plastic, paper, glass, metal, etc. , are varied. The current consumption of glass market share of pharmaceutical packaging. 10%, less than one third of the whole health food market. At the same time, because of the light, low price, processing and printing performance is good wait for a variety of excellent performance, plastic packaging seized the medicinal part of the glass bottles in health pharmaceutical packaging market. According to expert introduction, in terms of health care pharmaceutical packaging, our country have a certain gap compared with the international similar products, mainly is the material of glass. Medicinal glass has been widely used at present, the international borosilicate glass for packaging materials, the physical properties of the material is more stable, and can effectively protect the chemical properties of drugs and health food. But in our country, except for some small joint ventures and large state-owned enterprises using borosilicate glass material, the vast majority of enterprise of glass packaging still use the lime glass material, pharmaceutical glass manufacturing enterprises are still given priority to with nano calcium glass. In recent years, due to the development of pharmaceutical industry in China, pharmaceutical exports increased, to attach great importance to the quality of health care medicine glass by foreign investors, especially for some high drug price, often require glass quality inspection center testing certificate. Experts believe that the reasons for this phenomenon is mainly upgrades to keep up with packaging materials, and for packaging material enterprises with small profit for & other; Investment & throughout; With & other; Output & throughout; Missing is to plan as a whole and foresight.

authorities forecast, China may cancel within five years use class b material.

although the glass because of its features is relatively suitable for health care food packaging, but often with As203, Sb203 As clarifying agent for glass, so some contain the As and Sb oxide in the glass. Especially PbO, CdO sometimes As component was introduced into the glass, so international or national standards of advanced glass precipitation of As, Sb, Pd, Cd quantity are defined; Look from the glass, including glass product defects and problems existing in appearance quality. But for health food use glass, mainly refers to the internal surface water resistance. Such as 3. Within 3 borosilicate glass and neutral glass surface of the water resistance of HCI, while the neutral glass for HCI or HCB; Chinese medicinal neutral glass, on the other hand, there still exist some problems, such as alkali metal precipitation amount is higher, some may appear to take off. Are common problem of heavy metals is the international and domestic, there is no better solution, only by reducing the dosage of metal or use other material instead of solving. Look from pharmaceutical glass type, is of great importance to establish our country health care pharmaceutical glass standardization system. At present, the international standard ISO12775 & ndash; 1997 medicinal glass is available only for regulation, there are mainly international neutral glass, borosilicate glass, soda-lime glass 3 kinds. Among them, the soda lime glass not specified in this international standard medicinal, but as long as in other international standards regulations neutralization process and 121 ℃ water resistance up to level 2, can be medicine. But in our country in 2003 countries and drug administration approved by the pharmaceutical glass component classification and testing method of the industry standard set in the four kinds of glass, including neutral glass clear and use in our country, focusing on international neutral glass. Glass should be in line with international standards. Will tell from the glass, glass material mainly refers to the physical and chemical properties, of course, but the most important is refers to the chemical stability. Such as the international neutral glass and 3. 3 ShuiJunKe resistant borosilicate glass particle method to achieve grade 1. But our country water resistant most neutral glass particle method for grade 1, some for level 2. If look from the microscopic alkali amount of precipitation, the neutral glass times larger than the neutral glass in China. Experts with particular emphasis on soda lime glass also has asked for material after neutralization processing. In the international standard, to 121 ℃ water resistant is better than or equal to 2 grade, not all soda lime glass by neutralization processing can be used as a packaging container.
