In drug packaging, the aluminum foil gasket that is placed at the bottle mouth and often needs to be forcefully torn apart is by no means optional. It is a precision designed functional component that serves as a key defense line to ensure the safety and effectiveness of drugs.

I、Core function: Triple protection, safeguarding drug efficacy 

1. Barrier to ensure stable drug efficacy

This is its primary mission. The gasket forms a sealing layer with excellent airtightness and water tightness, which can effectively block water vapor and oxygen in the air, prevent drugs from being affected by moisture, decomposed or oxidized, and ensure stable composition and consistent efficacy within the validity period. 

2. Anti counterfeiting and tamper proof measures ensure medication safety

A complete sealing gasket is a visual proof that the drug has not been illegally opened. Once it is torn apart, it cannot be restored, providing crucial security for consumers and effectively preventing malicious pollution and counterfeiting. 

3. Bacterial inhibition and physical protection

For drugs with strict aseptic requirements, gaskets can effectively block the invasion of bacteria and microorganisms. At the same time, it can prevent drugs from leaking due to loose bottle caps during transportation and provide a layer of light protection. 

II、 Special intelligent function: Balance air pressure

For liquid preparations such as syrup and oral liquid, the sealing gasket can cleverly balance the pressure difference inside and outside the bottle caused by temperature changes, preventing the medicine from being difficult to pour out due to negative pressure or splashing due to positive pressure when opening the lid. 

summary

Although small, medicinal sealing gaskets are the "safe heart" of drug packaging. It silently guards every link of the drug from the factory to the hands of patients through multiple physical and chemical protections, and is the most loyal guardian of efficacy and safety.
