Pharmaceutical Coil is your traditional filler. It is used for packaging and ensures product freshness by absorbing moisture created inside the bottle. Coil can actually take up to one fifth of its weight in water before it actually feels damp. It is also used for the safety and cushioning of your product. During transit, pills can get broken and destroy the coating on the pills causing its dosage amount be less effective.

What are common types of Pharmaceutical Coil?

There are three common types of coil that are offered; cotton, rayon and polyester. Cotton is a natural fiber that is biodegradable and absorbs moisture created by tablets or capsules inside the bottle. Rayon is a synthetic fiber used to provide as a filler inside a container or bottle during transit to prevent tablets or capsules from damage. Polyester is a petroleum product that is odorless, soft, and resilient in material used for packaging soft-gel capsules.

How do I determine the amount of cotton I need for a particular bottle size?

When choosing the correct gram weight for your bottle, it is important to consider how coil is measured. Coil is measured by its weight per length or grams per yard. Please refer to the table below for suggested gram weights; the higher the gram weight, the thicker the coil.
