Packages for holding abrasive and oily food products, such as potato chips, crackers, and dry pet food, often require a combination of sufficient abrasion resistance and oil resistance. In this study, the interaction between abrasion resistance and oil resistance of a series of sealant materials were investigated. To correlate to shipping and storage conditions of food products, a shaker table test was developed to include both abrasion and oil penetration factors. During the test, a sealant film sample was adhered to the inside wall of a cylindrical shaped container, and an abrasive and oily food product was used to abrade the film inside of the container that was being shaken on a shaker table at a constant rate and temperature for a set period. A grading system was developed to quantify both abrasion and oil penetration levels on the tested film samples. Test results showed that oil penetration could significantly decrease the abrasion resistance of a sealant material, despite its abrasion resistance performance in a non-oily environment.
