The  rubber stopper  protects the medicine from environmental influences and helps maintain the quality and safety of the medicine. There are various elastomer formulations for stoppers. Natural rubber is a general-purpose elastomer, mainly used for water-based liquid filling products in the pH range of 4.0-7.5. Its resealability is an advantage in multi-dose applications. The formula uses dry natural rubber and no liquid latex. The post-treatment cycle (PEP 1) reduces the content of volatile extractables in the rubber c

As a manufacturer of  Aluminum Flip Top Seals , I will share with you. The use of bottle seals in pharmaceutical products is important for the following reasons: Bottle seals   help improve the safety of the bottle because it keeps the bottle from being tampered with. When the seal is intact, you know that the contents of the medicine in t he bottle are safe. The bottle top seal keeps the cap in place to prevent the contents of the bottle from spilling or leaking. This makes it easy for you to transport it from one place to another without losing the contents. Seals also protect you from counterfeit products and unfair practices in the marketplace. You will identify and associate a specific seal with a specific pharmaceutical company by the label on the seal. It keeps any external environmental elements from entering the bottle, thus maintaining the freshness of the bottle's contents.  In other words, the seal enhances the bottle's storage capacity by insulating it from oxygen

With excellent chemical stability, air tightness, low extractability and good biological properties, butyl rubber stoppers provide a reliable guarantee for drug quality.     ● Basic production process   There are two main production processes for butyl rubber stoppers at present.   ▷ Injection process Mating → Refining out strip → Vulcanization → Punching → Pre-cleaning → Cleaning → Inner wrapping → Outer wrapping   ▷Molding process Mating → refining (dense refining, open refining) → hot refining or extrusion pressing → cutting and weighing → vulcanization → punching → pre-cleaning → cleaning → inner packaging → outer packaging   ●Injection Curing Process For moulding, due to the poor thermal conductivity of the rubber, the internal temperature of the rubber layer rises slowly, and the temperature difference between the inner and outer layers is large, so when the outer layer enters the best vulcanization stage, the inner layer starts to vulcanize and is in the under-sulfur stage.
