TAPPI T829 Score Quality Test ie. TAPPI T829 Scorebend
Score Quality Test, Test Method
Overview of TAPPI T829 Scorebend:
TAPPI T829 Test Method is used to evaluate the quality of scores in corrugated shippers. Worn or misaligned equipment used in the box manufacturing (converting process) can cause inconsistent scores. The TAPPI T829 Scorebend Test is a method used to evaluate the flexibility of paper and paperboard by measuring the resistance to bending. The test involves applying a gradual increasing bending force to a specimen until it breaks, and the maximum force required to break the specimen is recorded as the scorebend value. The test can help determine the suitability of the paper or paperboard for packaging and other applications where flexibility is important. Purple Diamond Testing offers TAPPI T829 Score Quality Testing as part of our packaging compliance and validation services.
Rationale of TAPPI T829 Scorebend:
TAPPI T829 – Score Quality Test. This type of testing is a qualitative method of evaluating a corrugated shipper’s score quality. This is achieved by measuring the force required to bend a scored panel 90° and comparing the results to the force required to bend a non-scored section of the same material. TAPPI T829 Scorebend is a test method developed by the Technical Association of the Pulp and Paper Industry (TAPPI) for evaluating the folding endurance of paper and paperboard. The test measures the number of double folds that a sample can withstand before it breaks under standard testing conditions. The test involves scoring the paper or paperboard sample and then folding it repeatedly in the same direction, applying a constant pressure each time. The number of folds that the sample can withstand before it breaks is recorded as the folding endurance or scorebend value. This test is used to evaluate the strength and durability of paper products, and is an important quality control measure for manufacturers and suppliers in the pulp and paper industry.
