Functional fluid coatings for paper

The task

Specific properties for different products

Many products, such as packaging, often receive special solutions or functional coats. This is the case, for example, with twist packaging: A special solution applied onto the paper provides it with the desired elasticity, flexibility and stability. It also applies to filter and special papers exhibiting water, grease or dirt-repellent properties after impregnation. The challenge consists of returning the desired moisture to the material and furnishing it with properties in the exactly defined manner and quantity.

Finishing with liquids

The application of aqueous special solutions and functional coats grants the material properties such as elasticity, flexibility and stability.

The solution

Non-contacting liquid application

WEKO-Fluid-Application-System (WFA) such as WEKO-FLOW with WEKO-SIGMA, the finishing chemistry can be applied exactly. The material receives the specific properties through a non-contacting liquid application, which can also be reproduced at any time at minimum metering rates. This makes you highly flexible in production, while preserving valuable resources in addition. The WFA can be quickly and conveniently adapted to their production processes.

The realisation

Paper processing needs WEKO-FLOW und WEKO-SIGMA

WEKO-Fluid-Application-System (WFA) for the finishing of material webs are comprised of the Liquid Supply Unit WEKO-FLOW  and the WEKO-SIGMA Rotor Carrier.
