Various Wetting Measurement Techniques on Packaging Polypropylene

This work presents the results of investigations into the ability of the ballistic drop deposition technique to measure surface treatment in corona and flame treated oriented polypropylene films.

These measurements uncovered variation in surface energy of both treated and untreated material along the machine direction of the web, suggesting that more precise control of treatment level could result in a more uniform product.
