Seeking a biodegradable polymer (soil and/or marine water) which will retain its physical properties

Need Description:

• We are looking for a biodegradable polymer (soil and/or marine water) which will retain its physical properties when in contact with sterile aqueous formulations for up to 24 months at 38C
• No component of the coating 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 polymer should be thermoplastic
• Preferably processable by extrusion coating to give a flexible, non-tacky film.
• Possibly also processable via coating and drying of an aqueous dispersion

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:

• Non-biodegradable materials
• Oxo-degradable materials
