Cardboards are essential for a variety of packaging and shipping applications. They are lightweight, strong, and cost-effective materials used to protect products during transit. But do you know that the cardboard will get burst easily when force will be applied to it or due to rough handling? To ensure that the packaging materials will withstand the rigors of shipping, it is important for you to test the bursting strength of materials and ensure that quality products will be delivered. Bursting strength testing measures the force required to rupture or burst a material such as cardboard, corrugated board, or paperboard. This test is important because it can help determine if a particular type of packaging material is suitable for its intended use. Presto offers high quality bursting strength tester that is used to test the bursting strength of corrugated boxes and cardboard and ensure that quality products will be delivered to the customers.
Why bursting strength is considered to be an important quality factor in the packaging industry?
- By conducting a bursting strength test on the materials, one can easily ensure that quality products will be delivered so that the products will easily be assessed for any potential weakness.
- Bursting strength testing can also help to improve the design of cardboard products, making them stronger and more durable.
- Testing the bursting strength of cardboard ensures that it can support the weight and forces applied to them, so that they don’t break apart prematurely during use or while in transit.
- You can read more on the use of bursting strength testers in the paper and packaging industry. Now, let us discuss brief information about how the Presto bursting strength tester helped in testing the strength of corrugated boxes.
