Window Packaging, Simplified – Enabling transparent packaging windows in a single operation
The Challenge
Window packaging continues to grow across food, cosmetics, premium retail, and consumer goods as brands seek stronger shelf presence, improved product visibility, and greater consumer confidence.
Traditional production methods for windowed cartons often require separate patching operations where PVC or other transparent films are applied after printing and converting. While effective, these additional steps can increase production complexity, add handling requirements, introduce more equipment into the workflow, and reduce overall throughput.
Converters increasingly need solutions that simplify production while maintaining premium package appearance and performance.
The Solution
Derprosa™ Window Gloss Endurance (35F733), developed by Derprosa, a division of Taghleef Industries, was designed specifically to streamline window packaging production.
Using standard thermal laminators, converters can create transparent windows directly during the lamination process, combining lamination and window creation into a single operation and eliminating the need for separate window patching equipment.
At the core of the solution is a fast-cooling EVA adhesive system that becomes fully transparent after solidification, helping minimize haze and maintain excellent product visibility.
The Results
By integrating window creation directly into lamination, converters can:
- Simplify production workflows by removing secondary window patching operations
- Reduce handling and processing requirements
- Improve production efficiency and throughput
- Minimize waste during long production runs
- Maintain stable sheet stacking performance after cooling
- Achieve clean, high-gloss transparent windows with strong visual impact
The result is a more efficient process that supports premium packaging presentation without introducing additional complexity.
