Responsive image

From food supplies to office products, corrugated boxes are widely used in the packaging industry to deliver and store a vast amount of products safely to customers. These boxes are widely distributed to various manufacturing units and to make it easy for product delivery. The strength of these corrugated boxes will depend on various factors. GSM or gram per square meter is considered to be one of the crucial factors that will be used to determine the quality of these boxes easily.

In order to make sure that your products are of high quality, then you need to determine their GSM value first. For this, you can easily make use of a grammage tester and make sure that your products will be delivered without getting damaged. Here in this blog, we are going to discuss the importance of GSM in testing the strength of corrugated boxes.

Supply the corrugated boxes with perfection by testing their GSM 

The corrugated boxes are made up of pulp fiber and are subjected to corrugated rollers to convert them in the corrugated boxes that give the cushioning effect to the boxes and increase their strength. Depending on the usage and requirement of corrugated boxes, the manufacturing of these boxes may vary.

The GSM of the corrugated box will help you to determine the quality and weight of a sheet of paper in grams. If the GSM of the box will be higher, then the weight of the box is also greater. Thus, you can easily test the GSM value of the materials to decide their actual characteristics. Testronix Testing Instruments is considered to be the best basis weight tester GSM cutter manufacturer in India. We provide you with a high-quality Grammage kit that will provide you with an accurate measurement of GSM value.

It contains a GSM round cutter that helps in calculating the grams per square meter of the specimen that is being utilized in various industries for varied purposes. This testing instrument will measure the quality and resilience of materials. This is a very accurate testing device that will ensure precision in cutting the specimen.

The Testronix GSM cutter will precisely cut the sample in a round shape and ensure that you can easily measure the GSM of the sample. It has been provided with 4 built-in knives that make it easy for you to cut the sample precisely. By evolving the knob quarter of a turn, the cutter will produce a circular shape sample of 100 cm2. Materials used in packaging will vary from product to product. In some areas, heavy paper will be used, while in other areas the weight of the paper will be less.

This lab testing instrument is highly useful in determining the accurate quality of paper materials used to deliver the products efficiently. Once you cut the sample accurately with the help of a GSM cutter then you can easily determine the GSM for paper by using Testronix weighing balance. This testing equipment will provide you with an accurate grammage value of the specimen being tested.
