Micropake® is a phthalate-free X-ray detectable yarn based on polypropylene used in the manufacture of X-ray detectable gauze swabs and sponges.

The thread is typically made up of 40 filaments wrapped with a fine polyester thread and can be manufactured in a range of linear densities to suit customer specifications. This provides a key advantage in that the multi-filament thread is soft and flexible in nature, which when coupled with good tensile strength, allows Micropake® to be woven. The yarn may also be thermally or ultrasonically bonded to fabrics.

Micropake® is available in three different specifications that meet the x-ray opacity requirements of the British Pharmacopeia. 

All our products are manufactured in the UK, from class 8 clean room facilities located in Coventry. Our alginates, reinforced alginates, gelling fibre products are all manufactured from raw materials that are sustainable and using a manufacturing process which minimises waste as far as possible.
