Bottle Closures-4
Lithography Resistance to Pasteurization Conditions for Steel Crowns and Roll-On Pilferproof Aluminum Closures

VIEW METHOD

Summary
This test simulates the exposure of a crimped crown or an applied roll-on pilferproof closure to the caustic solutions that are present in a conventional pasteurizer. Some lithographic materials may be less tolerant to exposure than others. However, crown manufacturers usually have prescreened these coating materials for best pasteurization bath resistance. This test is used only as a confirmation test when problems are noted on crowns or closures that have exited pasteurization during production conditions.
