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.
