Poor quality packaged products will fall apart quickly, while good quality cartons are expensive. The thickness and quality of the paper will affect the structure of the corrugated paper. The edge compressive strength of corrugated boxes is evaluated by compressing samples of this material.
The Edge Compression Test (ECT) is a test method to evaluate the cross-directional, crushing test specimens of corrugated materials. This test provides complete information on the ability of a particular board to stop crushing. The Edge Crush Tester determines the compressive strength of the sides of packaging materials such as fiber solid boxes, corrugated boxes, etc. The machine is designed to standards for repeatable and accurate test results.
Procedures for setting up test machines are described in international and national standards. Test specimens with sharp and parallel cuts fit accurately on vertical surfaces. Use this test to evaluate the durability of a material. Raw materials should be tested before starting production as testing cannot be done after the production process has started.
The edge crush Tester compared boxes easily using McKee's formula. The compressive strength is k. ECT x T x Z. Here k is a constant, ECT is the edge extrusion value, T is the thickness of the sample material, and Z is the perimeter of the box. Ring crush Tester/flat crush Tester/edge crush Tester is a device for judging the crushing quality of corrugated boxes.
The Ring Crush Tester (RCT) determines the ring crush resistance of paper strips of standard length and width in a ring. The samples should be parallel to ensure correct determination of the compressive strength of the ring. The test results give the buckling behavior of the sample, not the crushing behaviour. A compressive force is applied to a sample held in a ring form in a special sample holder and placed in the machine's platen. Bring the driven platen close to the rigid platen at a constant speed until the sample collapses.
Flat compression Tester can help users provide flat compression test of corrugated paper. The Flat Compression Test has three types of grips, allowing the user to perform three types of compression tests on samples. The machine can perform three types of tests, namely ring pressure test, flat pressure test and edge pressure test. This test measures the crushing strength of the material and helps to maintain better strength and quality. The device provides results in a digital format and allows customers to obtain peaks from earlier tests performed on the same device.
