Nowadays, there are more and more types of aluminum-plastic bottle caps, including bottle caps, pharmaceutical bottle caps, infusion bottle caps, etc. aluminum-plastic bottle cap products have reached large-scale production, and aluminum caps are developing at a rapid pace. For the quality inspection of aluminum-plastic bottle caps, let's take you to understand. I like to provide a reference for everyone.
1. Convex edge detection is an indicator of the uniformity of the height of an aluminum-plastic bottle cap. The quality of the convex edge has a significant impact on the sealing of the bottle mouth when used by pharmaceutical companies. The convex edge in the standard is measured by the difference between the large and small heights of the bottle cap and the ratio of the small height.
2. The opening force and the removal force of the cap in the aluminum-plastic bottle cap directly affect the sealing of the bottle mouth and the convenience of the user. This method is performed using a tensile testing machine, so strict operating standards are required.
3. The material used for aluminum caps must be environmentally friendly and sterilized. Due to the fact that aluminum caps are often used for medicine bottle caps, if aluminum caps are contaminated, they may react with certain drugs inside or render the drugs ineffective. So the production of aluminum caps must be disinfected at high temperatures, etc.
Other inspection items in the standard. Operations such as compatibility, sterilization resistance, coating firmness, opening quality, etc. are carried out according to standard methods.
After understanding the quality inspection points for aluminum-plastic bottle caps mentioned above, I believe everyone has further learning and understanding. If you want to learn more information, please continue to follow us.
