rotoSLEEVE Hydrophobic is dedicated to processes where the easy assembly and disassembly of double-sided foams are required. They are designed to help printing houses where the speed of changeover plays a significant role in the output of the manufacturing process.

The outer layer of the sleeve has a physical and chemical treatment that creates a hydrophobic barrier. The hydrophobic barrier is permanent over time, significantly reducing the problems caused by moisture. This means it retains its dimensional stability better than the market standard sleeves.

These sleeves are dedicated to water and UV inks. They also excel where high dimensional stability of the sleeve and high print quality is required.
