Wide Web Cold Foil — Ultra-High Speed Rotary Transfer

What is wide web cold foil?

Wide web cold foil is a high-efficiency decorative consumable used in rotary printing to apply metallic or holographic effects without the need for heated dies. It utilizes a UV-curable adhesive and a pressure cylinder to transfer the decorative layer from a polyester carrier directly onto the substrate at full press speeds.

Overview of Wide Web Cold Foil Technology

In the evolving landscape of high-volume packaging, wide web cold foil has emerged as the preferred solution for converters seeking to add premium metallic finishes to flexible packaging, shrink sleeves, and folding cartons. Unlike traditional hot stamping, which requires expensive brass or copper dies and high temperatures, cold foil technology functions as an in-line process. This integration significantly reduces setup times and allows for the precise registration of foil to ink, a critical requirement for modern brand owners.

As a leading manufacturer-integrator, All-in Pack provides foils engineered specifically for the mechanical stresses of wide-format rotary presses. Our foils are designed with a unique multilayer structure that includes a release layer, a color coat, a vacuum-deposited aluminum layer, and a sizing coat that bonds instantly with UV-cured adhesives.

Technical Performance and Overprintability

One of the primary advantages of our wide web cold foil is its exceptional surface energy. This allows the foil to be overprinted using standard flexographic or offset inks. This capability enables printers to create an infinite spectrum of metallic colors by printing CMYK over silver foil, a technique that is both cost-effective and visually striking. The foil’s high-tensile 12μm PET carrier ensures stability across wide spans, preventing the "feathering" or "bridging" often associated with lower-quality consumables.

Key Advantages for High-Volume Converters

• Increased Throughput: Run at speeds equivalent to your printing press, often exceeding 100 meters per minute, which is impossible with traditional hot stamping.
• Cost Reduction: Eliminate the lead times and costs associated with die engraving and the energy consumption of heating systems.
• Design Flexibility: Achieve fine detail and halftone gradients that are difficult to replicate with hot foil or metallic inks.
• Waste Management: Our foils are compatible with foil-saving systems (multi-stepping), allowing for maximum utilization of the web width.

Integration with Post-Press Equipment

To achieve the best results, wide web cold foil must be paired with high-precision post-press equipment. The tension control systems on the unwind and rewind units must be finely tuned to match the press speed to avoid wrinkling or breakage. For converters looking to upgrade their current lines, we offer technical consulting to ensure our foils work seamlessly with your existing UV lamps and nip rollers. You can request a quote for specialized width requirements or bulk annual contracts.
