Importance of GSM and How to Calculate it?

GSM is one of the most important values for many different materials such as paper, packaging sheets and others. In most of the industries, the packaging is one of the most important aspect that is kept in mind when it comes to the safety of the products. When a products is manufactured in a company, the most important concerns about that is that the products is free from any defect. For that, there are different kinds of quality tests that are performed on the products to ensure that it is flawless from every aspect. This is necessary because if the quality of the product is overlooked, then it can cause damage to the products when it is subjected to actual working conditions, and eventually face failure. This can lead to fatal accidents in the industry where that product is used. Once there is a flawless product with best quality is obtained, the next concern is to deliver the product to the clients and consumers with complete safety so that the quality and integrity of the product is not jeopardized.

In order to deliver the products without any flaw, it is essential that the packaging of the products is chosen wisely. The materials that are used for packaging of products must be of best quality and must possess the enough strength that is required to ensure that the packaging of the products will remain intact throughout the delivery process. The packaging materials mainly used in the industries include the paper, cardboards, corrugated boxes, and fabrics. The packaging materials can ensure that the product is delivered to the clients in the safest manner and there cannot be any threat to the safety of the products. It is also use in Paper and Packaging Testing Instruments.

Strength of the packaging materials is very much dependent on many different factors. These factors include the molecular structure of the material, construction of the materials, weight of the materials and so forth. The GSM of a material can tell a lot about the strength of the materials. The GSM is the measure of weight of a material per square meter area of that material. This quantity is widely used in many different industries to determine the physical traits such as strength and construction of any material. The manufacturers of such materials need to ensure that they attain the right GSM value of the material to ensure its proposed usage with best efficiency. Different materials have different GSM and also different significance of GSM for different materials.

GSM of Paper

GSM of a paper gives a lot of critical information about its traits. Paper is available in the market with different sizes, qualities and strengths. The use of paper is prevalent in many industries for a variety of usages. It is used as stationary in schools and offices. It is the most basic resource for the printing industry as well. It is also used for wrapping and packaging of different products in different industries. Due to such crucial applications, the quality of the paper is very important and the manufacturers must keep in mind that the qualities of the paper they are delivering to the markets are of great importance. One of the most important aspects while analysing the quality of paper is the GSM of paper. The GSM of a paper is given by measuring the weight of 100 sq. meter sample of the paper being analysed. The GSM of the paper can help the manufacturers in deciding the quality of the products and hence deciding its price. As the GSM has a direct impact on the strength and agility of the paper, the manufacturers must ensure that the right GSM of the paper is incorporated and certain intended use. This also allows the manufacturers in optimizing their manufacturing process as well.

GSM of Cardboard

Cardboard is another very commonly used material in many industries. It used in art classes, schools and universities in different application and projects. They are also used as a major packaging material in the packaging industries as well as other industries. Cardboards is also used for making tubes and bases for any rolls. The cardboards are the materials that are made from recycled paper called paper. This flute is sandwiched in two different liners. These liners are also made from recycled paper or recycled old cardboards. As these cardboards are made from recycled paper, there are much chances that there quality is degraded during manufacturing if there are any errors of calculations or any human error. Additionally, these cardboards are used for critical applications such as packaging products. This is why the manufacturers need to ensure the best quality of cardboards by testing their strength and integrity. There many factors that can affect the quality and strength of the cardboards and hence must be tested thoroughly. The GSM of the cardboards plays an important role in deciding its strength. The cardboard is intended to be light but stronger hence the right value of GSM is supposed to be the best trait. The Strength and usability of a cardboards changes drastically with the changes in the GSM of a product.

Formula for calculating GSM

Weight per M2= (Weight of sample in grams per cm2) X 10000/ Area of sample in cm2

GSM of Corrugated Sheets

Corrugated boxes are the most widely used options when it comes to packaging boxes. The corrugated boxes are used for the reason that they offer the best strength and safety to the products that will be packaged in them. They are capable of bearing the heavy forces that can act upon them during the storage and transportation of the products from one point to another. The corrugated boxes are constructed from corrugated sheets that are prepared by placing one layer of sheet on another with the help of a string enough adhesive. The GSM of the corrugated sheet has a big role in deciding the strength of the box. Additionally, the GSM is also an important value that can be helpful in finding the bursting index and bursting factor of the corrugated sheets which is further very helpful in determining the overall strength of the products. The manufacturers can have the desired strength of the sheets by altering the number of layers in a corrugated sheet and hence can easily control the strength by making required changes in the manufacturing process. This helps the manufacturers in ensuring that the right strength corrugated box is used for the right application. There is no sense in using a very high strength corrugated box for an application where very low strength is required as it can cause losses. In this way, the calculation of GSM can be very helpful in reducing rejections and maximizing the profits.

GSM of Textiles

Textile materials such as Fabrics are also used for many different applications such as clothing, industrial cloths, tents, parachutes and so forth. There are many different processes involved in preparing the raw fabrics and make them ready for use. For example, the fabrics used for clothing need to be treated, desized, dyed, softened and scored before they can be used by humans. Also the strength of the fabrics is also measured so that they could survive the stressful conditions such as parachutes and industrial clothes. The GSM of the fabrics also has a great impact on the quality and strength of the fabrics that are used in different applications. When it comes to processing and dyeing of the fabrics, the GSM calculation of the fabrics is very much important in deciding the processes and procedures that are required to make the fabrics ready for usage. The dyeing of fabrics is done on the basis of the GSM as it gives the amount of dyes and other chemicals that are needed to get the intended results. If the dyeing and processing of the fabrics is not done according to the GSM, it can either waste a lot of colour and dyes during the process or it can lead to less colour usage and not getting intended results. Also GSM tell about the time required to perform the process on the fabrics. GSM not only helps in taking the processing decisions but it also helps in determining the strength and endurance of the fabrics as well so that it could be ensured that the fabrics will be able to bear the forces that they have to face during usage in actual working conditions.

GSM calculation

As the GSM value of any material is directly related to it is quality and physical traits, it becomes very important for the manufacturers of such materials to ensure that they are capable of calculating the GSM of a material with great accuracy. The manufacturers cannot take the chances of any errors in the calculation of GSM as slightest error in that can lead to drastic changed in the properties of the materials. This is why, the manufacturers must test the GSM of any material with great caution and accuracy.

In order to calculate the GSM accurately, there is a requirement of a cutting a piece of sample to be measured with the dimensions of 10cm X 10cm. This gives you a piece of 100 sq. cm. of the sample. Measure the weight of the pieces cut from the sample. Now the weight obtained is the weight of sample per 100 sq. centimetres. In order to convert it to per square meter, you need to multiply the obtained weight of the specimen with 100. This will give you the weight of the sample per sq. meter. This gives you the GSM of the sample easily.

GSM calculation with the help of GSM cutter

Most of the time, for the sake of accuracy, the GSM is measured using some tools so that there is no chances of error. As we discussed, any slight error in calculation of GSM can lead to drastic changes in the properties of the material. The GSM cutter is the tool that is used for cutting a round sheet from the sample to be measured. This sheet has an exact area of 100 cm square. The GSM cutter has sharp blades that make it easy and error free to cut the round sheet. This round sheet cut form the sample is weighed which gives the weight of the material per 100sq cm. When the weight is multiplied by 100, it gives the weight of the material per sq. meter which is the GSM value of the material being tested.

Pacorr is one of the most prominent GSM round cutter manufacturers and suppliers that offers a bundled kit including a GSM round cutter and a GSM weighing balance.
