Sizing press plays a crucial role in enhancing the paper’s absorption properties as it applies a starch layer, known as size, to the paper sheet to improve its strength, water resistance, and printability. The sizing press helps to improve the overall quality and performance of the paper, making it more suitable for various applications, such as printing, writing, and packaging.

The sizing press applies a controlled amount of waterproofing chemical to the paper sheet, which penetrates the paper & helps to:

• Improve paper strength and durability
• Reduce water absorption and improve water resistance
• Enhance printability and ink retention

It is typically located in the paper machine after the dryer section, just before the reel and consists of a series of rollers, including:

• A metering roller that applies the size
• A transfer roller that transfers the size to the paper
• A pressure roller that ensures even application
