For the manufacturers of paper and packaging industries, there are many attributes that help them to determine the quality. These quality related properties include the weight of paper, colour, burst strength, tearing strength, crushing strength, and much more. The major attribute which is significantly considered is the GSM value of papers. It is a measurements unit explained as grammage per square meter. This property helps to determine the strength and quality of material and helps to predict the best processing methods which are performed in paper and packaging industries such as scuffing, printing, fluting etc. In this blog section, we will share information on the two most common testing instruments used for evaluating GSM of papers, i.e. GSM Cutter and Digital GSM Balance.
In paper and packaging industries, it is important for the manufacturers to measure the GSM value so that accurate cost of the papers can be calculated.
GSM Evaluation of Papers
Precise measurement of GSM can be done easily by using Grammage checking kit. Presto Stantest Pvt. Ltd. is the authorized manufacturer and supplier of this kit and delivers high-quality instruments which comply with national and international standards.
The kit is a set of two different testing instruments:
- GSM Cutter –It is a highly standardized and precise device which provides a circular sample cut from the material. The cutter comprises a circular disc and four imported blades that cuts even the hardest samples easily and smoothly in no time with great precision. To use the cutter, a sample is placed on the flat surface and the knob of the cutter is slightly pressed and rotated in a clockwise direction. After rotating the knob release it to its normal position and you will get the circular size of the sample of diameter 100 cm2.
- Digital GSM Balance– It is a digital device which is used to check the grammage of all light weighed and a small piece of samples cut through the cutter. The balance is designed with sophisticated operating features and advanced software that help to operate the device easily. The software of the device also helps to connect the device to a computer in order to transfer or to save the results for future reference. The device has self—calibrated capacity with a feature of automatic calibration after every use.
