Evaluation of Film from Calliburn Industries
Evaluation of Film from Calliburn Industries
Background: There is interest in the corrosion protection offered by film from Calliburn Industries.
Purpose: Evaluate corrosion protection offered by Calliburn film.
Method: FT-IR Spectroscopy
Razor Blade Test
SO2 Test
VIA Test
Tensile Test
Materials: Paragon 1000 FT-IR, Perkin Elmer
Razor Blade Test Kit
SO2 Test Kit
VIA Test Kit
Calliburn film (blue in color, 4.0 mil)
Cortec VpCI™-126 film
Universal testing system, Instron 4443
Procedure: The above tests were performed according to standard procedures for each.
Results:
FT-IR Spectroscopy: Spectrum contains peaks corresponding to carboxylic acid derivatives (most likely sodium benzoate) and a possible triazole — based compound.

VIA Grades (Grade 2 or 3 are passing):
Grade 0- No corrosion inhibiting effect
Grade 1- Minute corrosion inhibiting effect
Grade 2- Medium corrosion inhibiting effect
Grade 3- Good corrosion inhibiting effect
SO2 Grades (Grade 3 and 4 are passing):
Grade 0- Extensive corrosion covering 25% or more of panel surface
Grade 1- Moderate corrosion covering 10-25% of panel surface
Grade 2- Slight corrosion covering 5-10% of panel surface
Grade 3- Very slight corrosion covering 0-5% of panel surface
Grade 4- No visible corrosion on panel surface
Conclusion:
- The Calliburn film does not provide any vapor corrosion protection and provides very limited contact corrosion protection for steel (see VIA and Razor Blade Tests results).
- Corrosion inhibitors in the Calliburn film are not acting as vapor corrosion inhibitors for steel and more recognized as very mild contact inhibitors. To provide sufficient corrosion protection these inhibitors should be used in combination with other chemical compounds.
- The Calliburn film has a poor quality, especially the tear strength and seal on the bags
