Multi-Layered Barrier Films

SunPro® Multi-layer barrier films are flexible films that prevent water, oxygen, light and other elements from entering or exiting a product’s packaging. Multi-layer barrier films are used in various flexible packaging applications including:

  • Bags
  • Pouches
  • Blister packaging
  • Forming webs and lidding

  • Faster machining speeds
  • Increased heat tolerance and strength due to ongoing substrate improvements

  • Extend shelf life
  • Reduce the need for preservatives
  • Provide transparency and gloss
  • SunPro® Multi-layer barrier film technologies help preserve perishable goods such as foods, beverages and pharmaceuticals. These films also:
