PATCH wound care strips are hypoallergenic and perfect for those with sensitive skin. Made with soft, organic bamboo fabric and gauze with hypoallergenic Pressure Sensitive Adhesive (PSA). Our PSA formulation is made from a combination of natural minerals and Nano technology (think tiny suction cups) to gently adhere to the skin without causing reactions. They are perfectly crafted for all sensitive skin types. The out-covers of the bandages are made from a biodegradable plastic. They can be placed in the recycling bin or, if it is placed in a rubbish bin, it will decompose.
