A corrugated cardboard box has layers of flat sheets called flutes that are compressed together by pressure from the sides.
The most common use of a box compression test is to determine the internal pressure of a box and how much force is required to reduce the thickness of the box.
This test can be used on carton or any other cardboard box of the same design and size.
Box compression test is an important procedure in order to measure the strength of a carton. A large carton can bear very high pressures, which leads to higher product durability.
The method of performing the test requires taking a cylindrical sample of carton. For a rectangular sample, four faces need to be measured. The samples are taken after the fluting of the carton has been removed. This is done using an air cylinder to squeeze the sides. The sample is placed in a vise and the bottom pressed down to hold it steady. The pressure is gradually increased by raising the head of the air cylinder.
The highest pressure is reached when the sides Box Compression Tester of the box reach a firm contact with a rubber block. It is necessary to note the pressure at which the sides of the box begin to bow, usually around 600 kg/cm². After this point, the pressure is increased at a rate of 0.
Box compression tests are done to measure the strength of cardboard boxes and corrugated sheets. These boxes are used for various types of packaging materials. Packaging is needed to protect products in transit. It is very important to have packaging that is strong. This is why box compression testing is done for packaging purposes. A box compression tester is used to determine the maximum compressive stress that can be applied to a given box and the resulting damage to the box. A machine called a “box compression tester” is used to perform box compression tests. The machine has special rollers which are rolled over the top surface of the boxes and a load cell measures the amount of load required to deform or compress the boxes. This information is recorded.
Box compression tests are usually carried out at a laboratory. The tests are performed on boxes that have been cut to standard lengths and dimensions. When these boxes are compressed, the resulting deformation (or lack thereof) is measured. This is recorded and compared with a baseline reading taken from an empty box. From this comparison, the box compression strength is determined.
Box compression tests are usually carried out on boxes that have already been used. The boxes that are used for packing are subjected to a compression test before they are sold to the customer. The customer is informed about the results of the test.
The box compression tester is a tool used to determine the mechanical properties of packaging materials. The tests are conducted to ensure that the materials meet minimum requirements as specified by ISO 8500-19.
The test results help to predict the capacity of materials to resist compression forces in cartons, corrugated sheets, and boxes. The test results are essential to predicting the durability of the cartons, corrugated sheets, and boxes. The box compression tester provides a method of testing the strength of materials which enables the measurement of tensile strength as a function of time.
The test involves placing the samples of material to be tested into a pneumatic piston device. The piston is pressed down on the sample until a specified load is reached. The pressure is held constant for a certain period of time.
When the sample is removed, its resistance to compressive force is determined as a function of load. This information is recorded for future reference. The box compression tester is widely used to test cardboard for commercial purposes. The test results are required by the European Union.
The basic principle of box compression tester is to simulate normal handling conditions of corrugated sheets or boxes during shipping, storage, and usage. The test parameters include loading rate, holding pressure, and testing duration.
Compression test for box corrugated is widely used to determine the ability of paper to withstand loads. According to ASTM standards, compressive strength is the minimum strength required to resist permanent reduction in volume of a material under specified conditions. Compressive strength is measured as the maximum load (force) per unit area that will result in a prescribed volume reduction.
The test is done by compressing the box corrugated with a ram to produce a load of 1 kN on the corrugated board to measure the compressive strength.
This machine can also be used for measuring the thickness of metal foil sheets. It also checks the accuracy of thickness of metal sheets.
The test determines how well the box corrugated can resist being crushed under pressure.
Why are compression tests conducted on corrugated boxes?
The standard is to determine whether the corrugated board resists being compressed under a defined force.
