This application relates to elastomeric articles such as gloves, compositions for producing the articles and methods for their manufacture. The elastomeric articles contain particles for detectability of the articles (or portions thereof) by metal detectors and/or x-ray detectors. The articles may contain two different types of particles – one particle type is selected from magnetic particles, highly conductive particles or a combination, and the second particle type is particles containing one or more high atomic mass elements (with an atomic mass of at least 132). The particles may be coated by a corrosion inhibitor coating, or they may be uncoated. The compositions for producing the articles may contain a viscosity modifier.

Abstract:
The present application relates to an elastomeric article, such as a glove, comprising: (i) an elastomeric film comprising one or more film layers, and including an external surface and an internal surface, (ii) an antimicrobial agent that is effective against both beneficial and harmful microorganisms on the external surface of the elastomeric film, and (iii) a skin- protective agent selected from a probiotic, a prebiotic, or a combination thereof on the internal surface of the elastomeric film; wherein the inner surface of the film is free of an antimicrobially-effective amount of an antimicrobial agent that is effective against both beneficial and harmful microorganisms. The elastomeric articles may further comprise a barrier film layer that provides separation between the antimicrobial agent and the skin- protective agent. Also described are methods for the manufacture of such articles.
