Testing the puncture resistance of flexible packaging materials

Test Summary

EN 14477 describes a test method of determining the puncture resistance of flexible packaging materials, including multilayer flexible packaging materials.

Test Procedure

A specimen of the flexible packaging material is fastened in a sample holder. A probe of specified dimensions penetrates the specimen with a constant speed. The force and elongation needed to penetrate the specimen are recorded.

Test Apparatus

  • Force testing stand capable of fixed speeds of 1, 5, 10, 50 or 100 mm/min.
  • Compression Load cell with fixture to hold the penetration probe.
  • 0.8 mm diameter penetration probe made of hardened steel with rounded tip of radius of 0.4mm.
  • Sample holder to secure sample in place during the test.
  • Software to control stand movement, capture force and displacement data, calculate, store and report results.


A minimum of 10 specimens shall be taken, evenly spaced across the reel or sheet being tested.

Samples should be conditioned at (23 ± 2)°C and (50 ± 5)% RH for 48 hours before testing. The test shall be carried out at the same conditions.


  1. A pre-conditioned sample is clamped into the sample holder
  2. The compression loadcell reading is zeroed before the probe touches the sample.
  3. The probe is driven through the sample at a constant speed of 1, 5, 10, 50, or 100 mm/min.
  4. The peak force in N is recorded along with the elongation in mm.
  5. For the determination of energy, the integral below the curve of force and elongation shall be calculated.
  6. The mean values and standard deviation of the values shall be calculated.

The test report shall include:

  • The reference to EN14477 standard
  • Date and place of testing
  • Description of the material being tested
  • Indication of which side of the specimen is being tested
  • The speed of the probe
  • Force at break in N. elongation in mm and energy in mJ
  • Any unusual features noted during the measurement
  • Any deviation from the method
