For packaging industries, it is critical to perform rigorous testing of materials as well as products to make sure that the packaging of the products is of best quality. The products must be packaged properly to ensure that they remain safe and fresh. The strength and quality of the packaging materials holds a great responsibility of the safety of the products. There are many types of packaging used for different kinds of products such as corrugated boxes, airtight containers, PET bottles, polythene bags, etc. All these products undergo proper quality testing procedures so that it could be ensured that the customers get only the high-quality products, and the products remain safe during transportation and warehousing. Below are discussed some of the testing methods used for quality assurance of packaging products in industries.

Compression test

A compression test is a major test that is conducted on the packaging boxes. As the packaging boxes undergo high compressive forces during transportation and warehousing, it is essential to test their compressive strength so that it could be assessed whether the box will be able to survive the journey or not., The box compression tester is used to test the compressive power of a corrugated box or carton. The computerized box compression tester is an extremely advanced instrument which gives exact and accurate testing results.

Edge crush test

The edge crush test is used for testing the strength of the walls of a corrugated box. The overall strength of the corrugated box greatly depends on the strength of the walls. The test is meant to determine the resistance offered by the corrugated board against crushing forces. This test is very helpful in determination of the maximum value of crushing that a box can bear during its actual usage and hence can be useful for prediction of the suitability of a particular packaging material for a particular application. For the best and most accurate test results, an edge crush tester is used. The same instrument can also be used for performing ring and flat crush testing.

Cobb sizing test

The Cobb sizing test is performed to determine the amount of water that can be absorbed by a corrugated box during usage. This helps in studying the effect of moist working conditions on the products.

Along with these, there is a dart impact test, vibration test, bursting strength test, puncture resistance test and many others are also used for proper evaluation of the force of the products. with these testing procedures, it becomes very easy to ensure the best quality of the products with the best quality of packaging.
