Top 5 Tips to Maintain Cobb Sizing Tester

In the packaging industry, the use of paper and its related products has been widely used in order to deliver the product accurately to the customers. Thus, it is important for you to test your products accurately, so as to increase your brand reputation. Therefore, we at Presto have come up with a Cobb sizing tester so as to determine the quantity of water absorbed by paper in a given time.

With the help of this amazing testing instrument, you will be able to determine the Cobb value or water absorptiveness which will be counted by a 1 sq. meter sample. Here, we will discuss brief information about the Cobb sizing tester and how you can easily maintain this lab testing instrument.

Introduction about Cobb sizing tester

The strength and durability of packaging products is the utmost factor that will help to make your product strong h durable. Thus, whether you are using paper boards or corrugated boxes, it is important for you to determine the Cobb value of these products.

Therefore, with the help of a Cobb sizing tester, you can easily measure the amount of liquid penetration your product can withstand. This cylindrical shape testing instrument comes with a flat base and a flexible backing on which the sample will be placed. The Cobb sizing tester will provide you with precise, and highly accurate testing results. You can also have a look at the significance of Cobb sizing tester in the packaging industry.

Purpose of Cobb sizing tester

The main purpose of using this lab testing instrument is to determine the amount of water being absorbed by the paper, paper board, corrugated fiberboard, and related products in a specified time. The water absorptiveness of paper will be related to different factors like sizing, porosity, etc.

A high COBB value indicates the ability of the substrate to easily absorb and retain moisture. A low COBB value indicates the ability of the substrate to resist penetration and retention of moisture. Thus, depending on the application of paper and its related products, the Cobb value will be maintained. 

This test method covers the determination of the quantity of water absorbed in a specified time by no bibulous paper and paperboard with a minimum thickness of 0.1 mm. You can easily perform Cobb sizing test, with simple and easy steps.
