Bursting Strength
Bursting strength, or simply burst, is a property of paper and paperboard which is used to determine the suitability of a product for an application. Bursting strength is closely related to the property of tensile strength, due to the internal fibre bonds being the source of the paper's strength. The test for bursting strength is predominantly used in packaging paper where the burst of the paper is a critical metric, and is a less common test for printing paper grades. The bursting strength test applies a hydraulic force to a sheet of paper that is located over a hole. As the hydraulic membrane fills at a specific rate it applies an increasing pressure to the side of the sheet which ruptures once the bursting limit is reached.
