DEF STAN 81-147 Standard Test for Water Vapor Resistant Material and Packaging Bags

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of DEF STAN 81-147 testing. This standard specifies requirements for three types of heat sealable, flexible, aluminum foil laminates suitable for use in packaging where low water vapor transmission rates (WVTR) are required.

These Ones;

  • Type 1 Non-woven plastic film backing
  • Type 2 Kraft paper support
  • Type 3 Woven natural or synthetic fiber backing

Type 1 is divided into two grades, A and B. Type 1B has greater tear and stiffness properties and a lower WVTR when bent and is used where a stronger material than Type 1A is required.

Use of Type 2 is not recommended when the application involves bending or stretching (unlike wrinkling) the foil laminate during packaging preparation procedure or service use.
