Types Of Coils

Pharmaceutical coil is available in three types of fiber: Cotton, Rayon and Polyester. Each provides distinct advantages and applications.

Cotton coil is composed of 100% bleached, absorbent cotton. It is selected for its clean, uniform fibers and is designed to give superior performance in packaging of pharmaceutical products.

Rayon coil is formulated of 100% rayon fibers providing a uniform fiber coil.

Polyester coil is a white, odorless, soft, uniformly carded, low moisture, resilient material.

Cotton fiber	Rayon fiber	Polyester fiber
Natural fiber	Man-made fiber(cellulose)	Man-made fiber(petroleum)
Variety of fiber lengths	Uniform	Uniform fiber length and denier
Easier with cutting cottoner equipment	Easier with tearing cotton equipment (rayon tends to dull knives in cutting operation)	Non-fluorescent
Absorbent - will absorb 22 times its weight in moisture, and moisture regain is 8.0% under normal conditions	Absorbent - will absorb 22 times its weight in moisture, and moisture regain is 9.0% to 11.0% under normal conditions	Non-absorbent - will neither introduce into or extract moisture from bottle, and moisture regain is .4% under normal conditions
Reoxygenates faster in bottle, resulting in a dryer environment	Most commonly used in bottling of tablets and capsules	Most commonly used in bottling of soft-gel capsules
