A3 Large Format Laminating

-- Steady & Reliable Manufacturer --

Expanding Possibilities with Wide-Entry Protection

While A4 is the standard for letters, the professional world often operates in larger formats. Our A3 Large Format Laminating series provides the 330mm entry width required for posters, menus, instructional charts, and oversized blueprints. These machines are engineered to handle the increased thermal demands of wider pouches, ensuring that heat is distributed perfectly from edge to edge to prevent the "wavy" finish often seen on lower-quality wide-format machines.

As a manufacturer, we focus on thermal consistency. Our A3 models utilize a 4-roller or 6-roller system with independent heating controls. This allows for the lamination of both standard 80-micron pouches and heavy 250-micron industrial-grade film. For print shops and marketing departments, an A3 laminator is a versatile asset that can handle everything from a small business card to a large-scale window display, providing a high-gloss or matte professional finish that protects against moisture, UV fading, and heavy handling.

Q: Can I laminate a standard A4 sheet in an A3 machine?
A: Absolutely. A3 machines are fully backward compatible with A4, A5, and smaller pouch sizes.

Q: Why does A3 lamination sometimes have bubbles?
A: Bubbles on larger formats are usually caused by uneven heat. Our 4-roller system pre-heats and then seals to ensure all air is pushed out.

Q: Is the machine much bigger than an A4 model?
A: It is wider (approx. 450mm-500mm total width) but maintains a similar depth and height, making it easy to store on a standard office side table.

Q: Does it have a cold setting for posters?
A: Yes, our professional A3 series includes a cold mode for heat-sensitive vinyl and large-format photographs.
