One of the challenges facing pharmaceutical packaging companies relates to the solubility and diffusion properties of certain drugs. These can result in interaction with the sealant layers of packaging film resulting in uptake of drugs by the lamination and the chemical breaking down of sealants.
Pharmaceutical packaging company Bemis Healthcare is currently investigating the use of Anobex™, an acrylonitrile methyl acrylate copolymer (AMAC) sealant produced by MSM Poly LLC, using advanced modeling techniques. The polymer sealant is suitable for packaging in‘difficult’ applications thanks to its high level of chemical resistance.
Bemis currently makes use of a range of sealants that include CXB® and PET high barrier sealants and believes that Anobex™ will be suitable as a replacement for Barex® applications. The investigation will include a process in which the sealant will be evaluated for equivalence to Barex®, and will include the evaluation of the supply chain supporting Anobex™.
