High Barrier Film Technology

  • Nano composite (clay, graphite)
  • Multilayer structure
  • Blending (PP/PE, PP/PVA)
  • Coating

수분과 산소에 대한 차단성을 동시 만족하는 소재 개발 필요

1 Polymer/EFG, 압출 복합필름 (Polymer/EFG, Extruded Composite Film)
  • 친수성(Hydrophilic)
    Graphite
    -OH : chemical, heat treatment
              exfoliation
  • 소수성 (Hydrophobic)
    Exfoliated
    Graphite
  • 폴리머 복합화 (Polymer Composite)

    Exfoliated
    Graphite

    Polymer
2 PVA/Inorganic, 코팅 (PVA/Inorganic, Coating)
  • PVA (Polyvinyl alcohol)
    - High oxygen barrier properties
    Poor moisture barrier properties
  • R: Crosslinking agent
  • Cross-linked PVA
    - Moisture sensitivity↓
    High O2 & H2O barrier properties
  • 산소차단성의 증가와 수분민감도를 줄인 고차단성 소재 개발
    (Development of the high barrier materials
    which increase oxygen barrier properties and decrease moisture sensitivity)
  • Target
    Market Expansion
    through a Combination
    of Different Materials
