Insolubilizers, as the name suggests, are used to render certain components of the paper insoluble, thereby enhancing the paper's resistance to various solvents, especially water. This feature is key in the production of specialty papers where added functionalities such as water-resistance or humidity-resistance are often required. By creating a barrier that repels water or other solvents, insolubilizers help maintain the integrity and lifespan of specialty papers, allowing them to fulfill their purpose in a diverse range of applications. When it comes to wood-free papers, renowned for their high-quality and longevity, insolubilizers play an equally crucial role. These papers are often used in applications requiring superior printing quality, such as books, magazines, or formal documents. Insolubilizers help preserve the printed content on the paper by preventing the ink from spreading or washing out. They allow the wood-free paper to resist the wear of time and usage, maintaining the clarity of the printed information and the paper's overall appearance.
ingredients to protect print integrity
Insolubilizers can contribute to production efficiency and sustainability in the paper manufacturing process. By enhancing the durability and resistance of papers, they reduce waste and extend the lifecycle of paper products. For paper manufacturers, the use of high-quality insolubilizers can add significant value to their paper products and support sustainable manufacturing practices.
Insolubilizers are used to help protect the integrity of a paper surface, providing stable viscosity during the coating color preparation. Our insolubilizers for the printing process are compatible with most coating additives and actively stabilize coating viscosity. Formaldehyde-free crosslinker, Berset™ 2720, rapidly reacts during coating consolidation allowing for curing to complete while still on the machine.

starch modifiers fight grease
paper & packaging takeout you can handle When ordering food to go, we all have experienced a paper bag or food container that has lost its structural integrity from being saturated with grease. This can be prevented by coating the inside of the food takeout container with a starch that stops oil from seeping through. These starches are treated with additives such as Indapro™ 5820 that help stop the bag from becoming soggy and creating a greasy mess.
sizing agents for water-resistance
paper & packaging protect your box No one likes a soggy box. Cardboard boxes travel miles and miles to reach their destination through all types of environments and weather; that’s why protecting a box on its journey is crucial. During the delivery process, these exterior factors can impact the integrity of items inside. With the correct sizing agents, water-resistant containerboard can be achieved. Two highly reactive hydrophobic sizing agents, Bersize™ ASA (Alkenyl Succinic Anhydride) and Xiran SMA (Styrene Maleic Anhydride), provide water-resistant properties to boxes while improving overall dry strength, without impacting final product friction.
