Film extrusion lines and metalizers present a special set of challenges to roll cover manufacturers. Homogeneous surface finishes, high release properties and tight dimensional tolerances require compounding and manufacturing expertise.
Engineered compounds from Stowe Woodward address the needs of the film extruder with a family of cover compounds that deliver good surface finishes absent of voids or occlusions and with the necessary release properties for smooth film processing.
High abrasion and temperature resistance ensure that the performance properties remain viable for the life of the cover.
Embosser
The embossing backing roll is used to achieve the optimal nip pressure required to transfer the embossing pattern to the web.
The successful cover resists wear, heat and retains its hardness for optimal performance and long life.
Corona Treater
The corona treater roll positions the film for the treatment that prepares the film for downstream printing or metalizing.
The ideal cover is highly resistant to electrostatic discharge and is homogeneous throughout the thickness of the cover without voids or occlusions.
