Evaluation of Oji-manufactured Stretch Film
Evaluation of Oji-manufactured Stretch Film
Background: Hiroyasu Fukuchi has interest in the corrosion inhibitor protection offered by Oji’s Stretch film
Purpose: Evaluate the corrosion inhibitor protection offered by Oji’s Stretch film.
Method: FT-IR Spectroscopy
Razor Blade Test
SO2 Test
Materials: Paragon 1000 FT-IR, Perkin Elmer
Razor Blade Test Kit
SO2 Test Kit
Procedure: The above tests were performed according to standard procedures for each.

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:
Oji’s stretch film does not provide contact or barrier corrosion inhibitor protection. Based on FT-IR results, this film doesn’t contain sufficient amount of inhibitors if any.
