Key Findings
Siegwerk has launched ‘Cirkit Novaseal,’ a new heat seal lacquer portfolio designed for the fiber-based and flexible packaging industries, delivering a consistent sealing performance, superior hot tack, and high bond strength. This innovative product series uniquely integrates circular economy strategies into its development, aiming to balance sustainability with high performance.
Technical / Clinical Details
The Cirkit Novaseal portfolio comprises multiple variants to cater to a broad spectrum of packaging applications. Key technical features include:
- Consistent Sealing Performance: Ensures stable sealing across different substrates and machine conditions, contributing to product protection and freshness preservation.
- Superior Hot Tack: Provides quick development of sufficient strength in the initial bonding phase on high-speed packaging lines, improving production efficiency by reducing the risk of line stoppages and increasing throughput.
- Low Seal Initiation Temperature: Engineered to allow sealing at relatively lower temperatures, enabling more energy-efficient processing. This contributes to reducing energy consumption during manufacturing and lowering costs.
- High Bond Strength: Delivers robust adhesion capable of withstanding physical stress and environmental changes, maintaining package integrity over long periods.
Siegwerk has embedded circular economy principles into the development of these products, considering material selection, production, and ultimate recyclability. This sets a new industry standard as demand for easily recyclable packaging solutions continues to grow.
