  • Plastic packaging which is not disposed of responsibly can result in persistent litter in the environment
  • Biodegradable packaging that is consumed by microorganisms if littered will be less of a long term problem
  • Until the point of disposal, however, the package must function to contain the product and maintain its stability
  • For packages which contain aqueous liquid product formulations the packaging must also provide an impermeable barrier to water loss under tropical conditions (MVTR < 1g/m2/day at 38C/90% RH)


Need Description

  • We are looking for a water barrier layer in a composite structure that will retain its physical properties when in contact with sterile aqueous formulations for up to 24 months at 38C
  • No component of the barrier should be extractable into an aqueous formulation inside the package
  • The aqueous formulations will cover pH range from 3 – 9 and water content from 10-90%
    • We prefer one solution, but would consider separate solutions which cover certain pH ranges
  • The barrier layer is preferably processable by extrusion coating or possibly via coating and drying of an aqueous dispersion
  • Upon disintegration of the package the barrier layer must also “disappear” without leaving microplastic residues (Dissolve, disperse, biodegrade…)


We Are Looking For

  • We would prefer an “off the shelf” solution which is commercially available
  • We would also consider emerging technology as a possible co-development
  • Only non-confidential information is acceptable


We Are NOT Interested In

  • Continuous metal layers, e.g. vacuum metallized aluminum, foils
  • Oxo-degradable materials
  • PVDC coatings


Please note that only non-confidential information describing the method, current use and IP can accepted for review.
