Seal strength testing
Package seal strength testing shows the peel separation force required to separate two flexible materials that are bonded together. This test is also called a T-Peel test.
Applications
  • Testing the seal on a sterilization pouch (Sterile Barrier System).
  • Test the seal on food packaging
    Purpose
    • Confirm the reproducibility of the sealing process. Create a baseline to screen for changes negatively affecting the packaging seal.
    • Determining if hot tack is creating a good seal.
    • Adherence to design specifications
    • Ease of opening for the user.
    • Determine the packaging's ability to protect product with the package.
    Standards
    • ASTM F88/F88M Standard Test Method for Seal Strength of Flexible Barrier Materials
    • ASTM D1876 Standard Test Method for Peel Resistance of Adhesives (T-Peel Test)
