Glass for drug - based packaging has more advantages than the packaging of other materials: the composition of the glass is simple, and it can ensure the chemical stability and drug properties of the drug. In this way, the use of glass packaging can effectively extend the shelf life of drugs.

Glass is easy to sterilize, good sealing, temperature resistant, anti internal pressure, especially glass tube used in drug packaging can resist great internal pressure, which is very important to the field of medicine. What's more, glass is also a recyclable environmental protection material.

The physical and chemical properties of glass tubes are not the same for all glass. The products of Jin Bora company's low borosilicate medical glass tube and control bottle series have distinctive characteristics and are the first choice for drug packaging. Jin Yuelai's glass tube has a uniform wall thickness, which is lighter than ordinary glass containers produced by other methods. In addition, Jin Yue glass tube is unparalleled clear and transparent, which is highly beneficial to the highly automated production process under standard optical control system.

The low borosilicate glass products produced by our company have excellent anti chemical, neutral and anti osmosis, which not only meet the requirement of neutrality in the container of injection liquid medicine, but also can be used in biologics.

Quality control

From raw materials to automatic production to storage, the whole process through the comprehensive quality control and advanced monitoring system to make the product conform to strict production standards. Ensure product quality is in line with the strict requirements of customers. In Jin Yue Lai company, every low borosilicate glass pipe has been strictly monitored by the laser inspection system on the production line.

The raw material in the factory is stored in batch storage at the specified storage site. The material is weighed by the material in the batching section, and the mixed material is added to the furnace head bin. The mixture that enters the kiln head bin is fused into the melting pool by the feeding machine, and the melted glass liquid is further cooled and homogenized through the flow hole into the material channel, providing the glass liquid that meets the molding requirements for the maffer furnace. The glass tube is formed by the Danner Fala tube production line of the flow material trough flow. After the heat insulation cover setting and the cooling of the drawing track, the glass tube is cut to a certain length according to the production requirements. At last, the circular tube is wrapped and wrapped by the glass tube after the artificial inspection, and then sent to the finished product library. Each process is strictly controlled according to the technological process.
