There are two types of unit systems that are commonly used when it comes to custom packaging: GSM and PT. Both have their own advantages and disadvantages, which can make it difficult to decide which one is right for you.
In this blog post, we will discuss the differences between GSM and PT so that you can make an informed decision about which system is best for your business.
What is GSM in Packaging and Printing?
GSM stands for grams per square meter and is a common measurement for the weight and thickness of paper products. In the world of packaging, GSM is often used to determine the basis weight of the corrugated boards. This measurement can be important for predicting stacking strength, print quality, and other properties of the finished product.
When ordering packaging materials, it is important to know the desired GSM so that the correct material can be selected. Too low of a GSM will result in a flimsy box that is more likely to tear or collapse, while too high of a GSM can make the box too stiff, causing difficulty in printing or folding. As with many things related to packaging, finding the perfect balance is key to achieving the best results.
What is PT Unit System in Packaging and Printing?
In the printing and packaging industry, the PT unit system is a standard way of measuring paper thickness. The system is based on the point size of type, with one point being equal to 1/72 of an inch.
The thickness of the paper is then expressed in points, with thicker papers being given a higher pt. value. For example, a sheet of copy paper typically has a pt. value of 80, while a sheet of cardstock may have a pt. value of 110. The PT system is a convenient way for businesses to compare the thicknesses of different types of paper, and to ensure that they are using the right paper for their needs.
If you’re thinking about converting to a GSM or PT unit system, what are the steps involved in doing so?
If you’re considering converting your measurement units to the GSM or PT system, there are a few steps you’ll need to follow. First, you’ll need to determine which system is best suited to your needs. The GSM system is typically used for industrial applications, while the PT system is more commonly used in the construction industry.
Once you’ve decided on a system, you’ll need to purchase a conversion chart or calculator. These can be found online or at your local hardware store. Once you have your chart or calculator, simply follow the instructions to convert your measurements. With a little effort, you’ll be using the GSM or PT system in no time.
When it comes to measuring weights and distances, the GSM unit system is the most commonly used system in the world. This system uses kilograms to measure weight and meters to measure distance. The PT unit system, on the other hand, is used primarily in the United States. This system uses pounds to measure weight and feet to measure distance.
Difference between GSM vs PT Unit System
The GSM unit system is based on the metric system, while the PT unit system is based on the imperial system. The GSM system uses kilograms to measure weight and meters to measure distance, while the PT unit system uses pounds to measure weight and feet to measure distance.
The GSM system is more commonly used worldwide, while the PT system is more commonly used in the United States. When converting between the two systems, it is important to use a conversion chart or calculator to ensure accuracy. With a little effort, you can easily convert between the GSM and PT unit systems.
Converting Between the GSM and PT Unit System
When it comes to paper, there are two main unit systems in use today: GSM and PT. GSM stands for “grams per square meter,” and is the metric system of measurement. PT stands for “pounds per thousand square feet,” and is the imperial system of measurement.
In general, GSM is used more widely in Europe, and PT is used more in North America. However, both systems are used in both regions, so it’s important to be able to convert between them. Here’s a quick guide to help you make the conversion:
- To convert from GSM to PT, divide the GSM by 1.488. For example, 80 gsm would be 80/1.488 = 54 pt.
- To convert from PT to GSM, multiply the PT by 1.488. For example, 54 pt would be 54 x 1.488 = 80 GSM.
Keep in mind that these are just rough estimates—the actual conversion will vary depending on the specific paper you’re using. But this should give you a general idea of how to make the switch between the two systems.
The use of GSM and PT unit systems in the packaging and printing industry
The use of GSM and PT unit systems helps ensure that the packaging and printing industry can operate with international consistency. The GSM system is used to measure the weight of paper, while the PT system is used to measure the thickness of the paper.
By using these two systems, businesses in the packaging and printing industry can be sure that they are using the same units of measurement as their counterparts in other countries. This international consistency is essential for ensuring that products can be easily shipped and received and that there is no confusion about the size or weight of order.
As a result, the use of GSM and PT unit systems helps to keep the packaging and printing industry running smoothly.
