It is the natural tendency of paper or pulp to absorb water or moisture from its environment, which can have a number of detrimental effects on the finished product. As a result, this absorption of moisture can weaken the material, leading to decreased strength and durability.
Moreover, if the material is used to package sensitive products, the water absorption can damage or even ruin the packed goods, making them unfit for your customers. Therefore, it is important to monitor the water absorptiveness of paper and other packaging materials in order to produce products with the desired performance. Thus, we at Presto have designed a high-quality lab testing instrument
known as Cobb sizing tester
. This highly standardized laboratory testing equipment
has been designed to test the amount of liquid penetration into a sheet of paper or board in a given amount of time.
In this article, we are going to provide you with information about Cobb sizing tester and how this quality testing equipment is useful in the packaging industry. Let’s get started with what exactly the Cobb sizing test entails & why it should be conducted in the packaging industry.
What is the Cobb sizing test and its importance in the packaging industry?
The Cobb sizing test
is a method used to assess the water absorptiveness levels of the product over a certain amount of time. Water absorption is an important characteristic of paper and cardboard, and is largely determined by its porosity, sizing, and other physical properties.
With a high Cobb value, these materials are able to absorb and retain more water, which is essential depending on their intended application. The Cobb size test measures the amount of water absorbed by a paper sample of 1 sq. meter over a specified period of time, providing an accurate assessment of its water absorptiveness. Monitoring this value is critical for ensuring that the paper or cardboard meets the required standards of performance.
The main purpose of conducting the Cobb sizing test
will help the manufacturers in ensuring that quality material will be delivered to the customers. Now, let us discuss brief information about Presto Cobb sizing tester
. So, let us get started!
All about Presto Cobb sizing tester
The Cobb sizing test is an important quality test used in the packaging industry to determine the absorbent capacity of paper and paperboard. This test measures the amount of water that a sample of paper or paperboard can absorb in a specific amount of time under standardized conditions.
The results of the Cobb sizing test are used to assess the suitability of paper and paperboard for specific packaging applications. Thus, this quality test helps packaging manufacturers to select the appropriate paper and paperboard for their products, ensuring that the packaging materials are able to protect the contents and maintain their integrity during storage and transport.
Thus, we at Presto have designed a high-quality lab testing instrument known as a Cobb sizing tester machine to measure the water absorptiveness of a substance at a given period of time. It consists of a cylindrical container that is clamped to a flat base with flexible backing on which the sample will be placed.
This TAPPI T 441 Cobb Test
will be performed on different industries including paper & packaging to ensure the quality of the material will be delivered.
Now, let us discuss brief information about Presto Cobb sizing tester.
