Aims:
  1. To develop a high-barrier coating containing no halocarbons, by
    1. Substitution of Parylene-N for Parylene-C.
    2. Substitution of Parylene-C with laminated face sheets of BOPP and related polyolefins.
  2. To identify the minimum thickness and areal density that achieves the desired barrier and mechanical properties, without compromising ease of handling.
  3. To develop an edge sealing technology based on heat curing of crosslinkable coatings that has comparable barrier properties to the polymer film.
  4. To conduct a detailed study of the barrier properties of edge-sealed enclosures subjected to,
    1. Retort sterilization.
    2. Exposure to hydrophilic agents, pH 4-10.
    3. Exposure to oils.
    4. Accelerated testing of filled enclosures at 90 deg C and 110 deg C.
  5. To investigate the use of polyetheretherketone (PEEK) as a lower cost, high transmittance alternative to polyimide.
  6. To conduct a GLP assessment of food contact safety with the objective of attaining FDA Food Grade certification.
