Anyone who has known carton products has heard of burst resistance, so do you know what burst strength is?
Dongguan Carton Factory will bring you an in-depth understanding. Bursting strength refers to the maximum uniformly increased pressure perpendicular to the surface of the sample that paper or cardboard can withstand on a unit area under experimental conditions. The bursting strength reflects the ability of the carton to withstand the force of handling, loading and unloading, impact, and tearing during the circulation process, and is one of the evaluation methods for the comprehensive performance of the carton. In addition, different regions and different carton factories have different names for bursting strength. In addition to bursting strength, it is also known as bursting strength and bursting strength. In some places, bursting strength is commonly called "pounding".
There are several methods for measuring burst strength, but the most common is the Mullen test. This test involves clamping a sample of the material between two circular plates and applying pressure until the material ruptures. The pressure required to cause the rupture is then recorded as the burst strength.
Carton products typically have a burst strength rating that ranges from 175 to 275 pounds per square inch (psi). However, in some cases, carton products may have a burst strength of 1,500 psi or more. This high level of burst strength is particularly important in industries that require heavy-duty packaging, such as shipping and cargo.
There are several factors that can affect the burst strength of carton products. One of the most important is the type of material used to make the carton. Some common materials include corrugated cardboard, solid board, and paperboard. Each of these materials has different properties that can affect the burst strength of the carton.
Corrugated cardboard, for example, is made up of several layers of paper that are glued together in a specific pattern. This pattern creates pockets of air between the layers, which helps to absorb shock and increase the carton’s strength. Solid board, on the other hand, is made up of a single layer of paperboard that is thicker and denser than traditional corrugated cardboard. This material is often used for heavy-duty applications, such as packaging machinery and equipment.
Another important factor that can affect the burst strength of carton products is the design of the carton itself. Cartons that are designed to hold heavy items, such as machine parts or electronics, may have additional reinforcement in key areas to prevent rupture. Similarly, cartons that are designed to be stacked on top of one another may have increased burst strength to prevent crushing.
Bursting strength is an indicator of the physical strength of paper and board. It refers to the uniformly increased maximum pressure of paper or cardboard perpendicular to the surface of the sample on a unit area, expressed in kpa. It is usually measured on the Mullen Burst Tester (Mullen) of the annular pressure ring. The value obtained directly on the instrument is called the absolute bursting strength. The burst index of paper or cardboard can be obtained by dividing the absolute burst strength by the paper weight. Predicting the ability of corrugated cardboard to resist extrusion by external force by detecting the bursting strength of corrugated cardboard is a reflection of the static anti-extrusion ability of corrugated cardboard. The bursting strength reflects the maximum pressure that the cardboard unit area can withstand uniformly increased in the vertical direction, and reflects the ability of the carton to protect the product when it is squeezed under static conditions during transportation. Therefore, if you have load-bearing requirements for cartons, you can ask the carton factory to match the paper for you according to the bursting strength you need, or you can ask the carton factory to conduct experimental operations on your cartons, and use the data to speak.
