The Right Film for a Tricky Formulation: Tekni-Plex helps Altrazeal® Powder for Wound Treatment adopt a novel packaging solution
Altrazeal® from ULURU Inc. – a powder that transforms into a three-dimensional, micro-porous film that contours to the shapes of wounds – was recognized as an advancement in wound management. However, the groundbreaking formulation came with one significant disadvantage: due to various factors – most notably the formulation’s extremely low density – it was exceedingly difficult to package the product in a manner that optimized its unique performance.
Tekni-Plex became involved in the project when it was evident that traditional blister materials were not providing the required moisture barrier. Tekni-Plex developed a sheet co-extrusion process where a high-moisture-barrier COC resin is combined with polypropylene “facing” layers, creating a symmetrical sheet perfectly capable of being thermoformed into blisters. The resulting blisters find use in applications where low moisture permeation rates need to be achieved.
