Flexible packaging rollers coated in polyurethane: performance and reliability π οΈ
Flexible packaging rollers are essential components in industrial processes where precision, continuity, and final product quality are crucial. In this specific case, the rollers are coated in polyurethane with a hardness of 80 Shore, dimensions L.1500 mm and D.350 mm, ensuring high wear resistance and consistent performance over time βοΈ
The polyurethane coating is not processed as a standalone material, but applied to the roller to enhance its functional characteristics, ensuring grip, controlled elasticity, and durability even under intensive operating conditions.
Flexible packaging rollers: precision surface finishing
Flexible packaging rollers are ground to achieve an ΰ€ ΰ€€ΰ₯ΰ€―remely precise surface finish. Afterwards, cross spiral grooves are created π, a technical solution that allows air evacuation during contact with the processed material.
This prevents the formation of air bubbles between the roller and the product, significantly improving final quality. This feature is particularly beneficial also for applications such as rollers for paper and cardboard and printing machine rollers, where uniformity is essential π¦
Flexible packaging rollers and available coatings
In addition to polyurethane, rollers can be supplied with various rubber and polymer coatings, provided through qualified external partners π€
Available materials include:
- Silicone
- Hypalon
- Polyurethane
- Neoprene
- EPDM
- Viton
This variety allows support for multiple industries, including those requiring tissue rollers and rollers for paper mills, where coating properties directly affect performance π
Custom elastomers based on specific drawings are also available upon request.
