Pharmaceutical Desiccants offer Foam Plugs that are white cylindrical shaped blocks and also produced in block foam plugs made of urethane. They are widely used as fillers within bottles. Bottle stopper foam plugs are void space fillers and protect tablets and capsules from chipping due to rattling while shipping. Bottle stopper foam plugs are ideal for mechanical damage in medicines. The foam plugs for pharma bottles are manufactured to be chemically resistant and are a beneficial method for closing sterile containers to protect medication. Foam Plugs are non-toxic & non-reactive, auto-cleavable, and manufactured in blocks. These bottle stopper foam plugs are passed through the South African Bureau of Standard Tests: SANS 640-2005. This test is conducted for weight, density, aging, and solvent resistance. However, due to its structure like an open cell foam, it is soft and flexible so that the foam can be easily squashed into the bottles. Therefore, foam plugs for pharma bottles are versatile for all applications and can be customised per size and thickness requirements.
