Why Consider GSM While Testing The Strength Of Corrugated Boxes

Corrugated boxes are essential equipment when it comes to packaging the products and delivering them to customers safely. Be it the food, office product, or any other product, these boxes are demanded by a number of manufacturing units to make easy the delivery. Of course, strength is one of the various factors of their popularity. And there are several factors on which the strength of these boxes depends, including the GSM.

GSM is an important factor in determining the paper strength and quality and is evaluated using a GSM testing machine for paper. In the following section, we are going to discuss why GSM is crucial in measuring the strength of corrugated boxes.

What Is GSM?

GSM stands for Gram Per Square Meter. When it comes to measuring the strength of a corrugated box, the thickness of the paper it is made of is measured in terms of the weight of the material per unit area. This is called GSM. it gives a lot of information about the physical traits of the paper.

Importance Of GSM In Testing The Strength Of Corrugated Boxes

1. The GSM of a corrugated box helps in evaluating the strength and quality of a paper. Paper is being used dynamically in different domains, be it printing, stationery, packaging, wrapping, etc. This makes it inevitable for manufacturers to ensure the quality of the paper, they are providing to the markets. And GSM helps in determining this quality.

1. It even helps manufacturers in determining the quality of the products and their price. Hence, they must make sure that the accurate GSM of the paper is employed for the proposed use.

1. GSM is also important in measuring the weight of the corrugated box. The higher the GSM of the paper, the greater the box weight is. Hence, this factor indirectly helps in determining the weight of the boxes when the shipping charges need to be reduced.

1. GSM also plays a vital role in determining the bursting index and bursting factor of the corrugated sheets. This ultimately helps in deciding the entire strength of the products, hence the right strength corrugated box is used for the right application. This also reduces rejections and boosts profits.

Calculation of GSM

Since the GSM is directly related to the physical traits and quality, it is important for the manufacturers of materials to calculate the GSM precisely. They must avoid the risks of any errors in the calculation, as this may lead to unacceptable changes in the material properties. And due to this reason, manufacturers must use the grammage testing machine. By weighing a small test sample of the material with given dimensions, the instrument will provide the GSM or the basis weight of paper or corrugated sheet.
