Medical Antimicrobial Film and Bag Compound (PLA/PBAT)

About This Product

This grade is a medical compound of polylactic acid and polybutylene adipate terephthalate carrying an antimicrobial modification, supplied as a pellet compound for film and bag production. PLA contributes stiffness and modulus, while PBAT is a flexible aliphatic-aromatic copolyester supplying the tear strength, elongation and sealing behaviour a bag needs. Films and bags used in clinical settings can carry organisms on their surface between handling steps: a bag is filled, set down, picked up and moved between areas, and every contact is an opportunity for transfer. An antimicrobial modification in the polymer reduces surface colonisation rather than relying on cleaning alone, and because the active is distributed through the film rather than laid on top of it, the function is not removed by wiping or abrasion as a coating would be. The corollary is that only the fraction of active at or near the surface is available to act, so loading, dispersion and film gauge all bear on performance. Antimicrobial efficacy must be established on the finished article against the relevant test method and the organisms of concern. Manufacturing a medical device from this compound requires the manufacturer's own regulatory approvals, including an appropriate quality system such as ISO 13485. We supply the material and make no clinical claim. It is used in medical films and bags, clinical waste bags and healthcare packaging. Bio Green Chem supplies the medical grade antimicrobial PLA/PBAT compound to specification on polymer ratio, antimicrobial loading, melt flow for film extrusion and pellet form.
