Decurling due to moisture control
Multilayer film and other multilayer polyolefin composite materials often have a tendency to curl. These curling tendencies lead to disruptions in processing operations.
YOU DONT`T LIKE TENSION - NEITHER WE DO.
During the production of multilayer web materials, tension can occur between the layers. The causes are usually differences in the cooling phase or moisture absorption. Since the layers are firmly bonded to each other, these tensions create unwanted curling of the entire material web. By applying minimal moisture, this curling effect can be eliminated or at least very reduced.
Advantages at a glance:
Precise, minimal and repeatable application quantities
Resource-saving due to minimal consumption
Contact-free application
No wear and tear or order-related exchange parts
High flexibility - single or double-sided application possible
Intuitive, easy operation
With the WEKO-BASIC or WEKO-FLOW in combination with the WEKO-SIGMA rotor carrier, it is possible to apply minimal amounts of fluid and distribute it evenly by a smoothing unit.
The curling tendency of the composite film is significantly reduced and enables optimum behavior in further processing.

„A diversified portfolio“
EK-Pack Folien GmbH, based in Ermengerst-Wiggensbach, was founded in 1977 and has been run as a family business ever since. With 210 employees, the company develops and produces modern film systems, achieving an annual output of over 30,000 tons.
The complex requirements of the sales markets are met by comprehensive know-how, reliable and motivated employees as well as modern production facilities. The wide-ranging portfolio of flexible films is used in particular in the food, non-food and medical/pharmaceutical sectors.
„Sustainable protection of our everyday needs“
Aligned with the realization of the vision: “Sustainable protection of our everyday needs,” KP is a leading global supplier of rigid and flexible packaging and specialty film solutions for pharmaceutical and medical devices, food, beverages, and cards.
Since 2009, WEKO’s silicone spray-on process has been successfully used at various Klöckner Pentaplast facilities. The system is used in the production of PET films made from 100% recycled material, which are then further processed into thermoformed trays. When spraying on the silicone/water mixture, the primary aim is to denest the trays (anti-blocking).
„Leading manufacturers in Europe“
The SÜDPACK Packaging Group is one of Europe’s leading manufacturers of coextruded flexible and rigid films, flexible plastic composites and bags.
Another focus is on printing films using flexographic, gravure and digital printing processes. The family-owned company has a total of 18 sales offices and sites, with production facilities in Germany, France, Poland, the USA and Switzerland.
