Background
- 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
