Sud-Chemie Performance Packaging has introduced a new type of desiccant gasket to ensure that pharmaceutical products are safe from moisture damage. The desiccant is located at the junction of the bottle cap and the bottle, ie the neck of the container containing the drug. This type of gasket is suitable for packaging where it is not convenient to use bulk desiccant, one of which can also be used on bottles with induction seals. Because this type of gasket can be easily removed after opening the bottle, it is particularly effective in protecting powdered medicines.
