Determine the Liquid Absorptiveness Of Corrugated Packages

Determine the Liquid Absorptiveness Of Corrugated Packages 

When a customer is going to store to purchase an item, sometimes damaged products can hamper the manufacturer’s image in the market. But in the e-commerce world, customers do not have the luxury of physically inspecting an item before they buy, making this quality control process more critical. While in transit, there’s chance that packages may get damaged because of improper handling or water exposure.

Damaged products are a huge pain points to the manufacturers of packaging industry as the contents inside the packages get damaged and the spoilt due to moisture absorbed by the contents. The cost of replacing damaged products is high that includes the shipping cost to send the damaged item back to the merchant, the shipping cost to replace the damaged product with a reshipment.

Water and humidity Damage

Packages are transported to long distances and in between the product must undergo changes in temperature and a shipping route can lead to damages. Sometimes unattended packages left outside the customer’s home can damage the package and the contents inside. Extreme variations in temperature and humidity can cause corrosion or product ruining mildew.

A packaging process requires regular checks which is necessary for quality results. To meet such requirements, several testing instruments are manufactured in the market. Cobb Sizing Tester is of great value to the paper and packaging industry. The instrument tests the liquid absorption capacity of paper, corrugated sheets, fibreboards, and other packaging material. To determine the water absorptiveness by the paper in the given time, Cobb Sizing Tester is used under standard conditions.

The cobb value is determined by weighing the water absorbed per unit square meter of corrugated sheet or paper at ta given time.

How does Cobb Tester work?

A test sample is pre-weighed on a balance and placed inside the Cobb equipment when it is dry. A fixed amount of water is filled into the cylindrical container. The time is noted on a stopwatch. Once the test time is over, the sample is taken out and the excess of water is drained out using a roller. After that, the weight of the sample is taken. The difference in the weight of dry and wet sample gives its cobb sizing value.

Pacorr offers packaging industry with several testing tools relevant to quality manufacturing. Cobb tester is in demand for accurate result and reasonable rates. The instrument has a metallic base covered with a sheet of flexible material. The stainless-steel body is equipped with strong clamps to grip the sample properly. The Cobb Tester has a soft rubber sealing gasket to avoid water seepage. To meet the challenge of manufacturing process, the company delivers customised testing solutions at reasonable rates.
