One of the most important fact that must be kept in mind while choosing the packaging material is the introduction of the moisture to the packaging material. The moisture or water can disturb the molecular integrity of the material and cause extensive damage to the materials. The manufacturers need to ensure that the quality of that the packaging material they are manufacturing is able to absorb the moisture or water without facing any damage to ensure protection of the products. The Cobb Sizing tester manufacturers and suppliers develop the testing instrument is used by the manufacturers of packaging containers to test the water absorbance of the materials when subjected to moist condition.
The Cobb Sizing is the amount of water that is absorbed by a material in a moist environment and it is tested using this testing instrument.
Pacorr’s Cobb Sizing tester is one such instrument that is extensively used in packaging industries to test the water absorbance quality of the products and ensure best quality of the packaging materials. The packaging containers are often introduced to environment that have extreme moisture and water hence can face very great damage and can be proved to be harmful for the products as well. This demands the manufacturers to focus their attention on the water absorbance of the materials that are used for packaging.
The Cobb Sizing tester manufacturers and suppliers design the instrument that is capable of providing the accurate testing of the Cobb Sizing of any material. The Cobb Sizing is the amount of water that is absorbed by a material when it is immersed in water. The instrument comes with stainless steel container which contains water. The container is placed on a fixture which holds it. The specimen to be tested is weighed before commencing the test procedure. The container is filled with water and the test specimen is immersed in the water for a specific amount of time of 120 seconds. After that time the specimen is taken out. There is a stainless steel roller given with the instrument that is used to take all the water out of the specimen. The specimen is again weighed and the Cobb Sizing is calculated with the help of the following formula.
Cobb Sizing = Weight of the specimen after test procedure and weight of the specimen before test procedure.
The instrument is very easy and simple to operate and does not require any electrical power to operate. The body of the equipment is made from high quality mild steel as well as stainless steel and powder coated which ensures rigid operation and long service life.
- Inner diameter of reservoir: 112.8 mm
- Area of opening of reservoir: 100 cm2
- Height of reservoir: 25 mm
- Diameter of SS roller: 100 mm
- Length of SS roller: 200 mm
- Weight of SS roller: 10 kg

A Cobb sizing tester is a specialized instrument used primarily in the paper and packaging industries to measure the water absorption rate of paper, cardboard, and other sheet materials. This test helps determine the material's resistance to moisture, which is crucial for many packaging applications.
The Cobb test is vital because it helps manufacturers ensure their materials meet specific quality and durability standards. For industries where moisture resistance is essential—like food packaging, pharmaceuticals, and cosmetics—knowing the water absorption rate of packaging materials can significantly impact the product's shelf life and safety.
The Cobb sizing tester works by measuring the amount of water absorbed by a sample material in a specific area over a fixed time. The process involves placing a measured amount of water on top of the material sample confined within a testing area, allowing it to absorb for a predetermined period, and then removing the excess water to weigh the sample and calculate the water absorbed.
While the Cobb sizing tester is primarily designed for testing paper and cardboard, it can also be used to assess any sheet material's water absorption properties where understanding moisture resistance is critical. This includes certain types of nonwoven fabrics, thin plastic sheets, and other similar materials.
Choosing Pacorr's Cobb sizing tester offers several advantages, including precision, reliability, and compliance with international standards.
