Why GSM Testing is Important in Paper Industry

Determining the GSM of a paper is essential when it comes to knowing about the quality and characteristics of the paper for a specific purpose. GSM or Grammage per Square Meter is a unit for measuring the weight of the paper or board. 

Measuring this property is essential, especially with corrugated boards and boxes. This is because creating strong corrugated boards is crucial for the packaging industry, as this extremely affects the cost of the product and customer satisfaction. GSM acts as a robust parameter to determine the quality and durability of the paper and its aptness for the desired usage. And it is due to this reason that manufacturers make use of UEC’s digital GSM testing machine. 

You might have heard that the higher the GSM of the paper, the heavier its weight is. That’s true. A corrugated board with a higher GSM typically suggests a stronger and more enduring box. And that also reflects a higher cost of the box. 

Factors Affecting the GSM of a Corrugated Box

Now, there are several aspects that can influence the GSM of a paperboard. The vital factors include the quality of the paper, the manufacturing process, and the method of corrugation. Let us understand these factors below.  

• The type of paper used to make the board is a crucial factor that influences its GSM. If the paper is high-quality and heavy-duty, the box will have a higher GSM and hence will be durable. On the contrary, one that’s light in weight will create a lower GSM board, and hence the box will be less enduring.
• The second vital factor is the paper manufacturing process. Paper testing instruments speak a lot about this factor when paper specimens are tested. A higher-pressure paper-making process results in a higher GSM paper, while a lower-pressure manufacturing process gives a lower GSM paper. 
• Lastly, the corrugation method plays a vital role too. A single-face corrugation method gives a lower GSM paper. On the contrary, a double-face corrugation method makes up a higher GSM paper that is long-lasting.

Hence, GSM plays a significant role in comprehending the quality of a paper and a Digital GSM testing machine can help manufacturers understand it effectively.
