  • Responsive
  • Project Size Range : 50,000 - 250,000 €
  • Deadline completed
    The submission process for new proposals is closed. Proposals submitted before the deadline will follow the standard evaluation process.

Desired outcome

• 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)

Details of the Innovation Need

  • 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
