In the packaging and printing industry, metallic cardboard holds an important place thanks to its unique advantages. It is rigid, has a natural sheen, and comes in a wide range of colors. Common gold and silver finishes exude a high-end texture, and options include aluminum foil based and PET aluminum film based metallic cardboard. The color depth and brightness can be adjusted, the surface can be glossy or matte, and various embossing patterns are available. This makes it widely used for packaging boxes and cases in industries such as FMCG, cosmetics, pharmaceuticals, and gifts.
The base paper for metallic cardboard is also highly diverse, including white card, coated paper, offset paper, recycled paper, gray board, white-backed white board, red card base, and more. Moreover, custom services for various gold and silver cardboard and packaging boxes ensure print quality and effect before mass printing, laying a solid foundation for subsequent production.
However, as good as metallic cardboard is, slitting it is no easy task. The requirements for slitting are relatively demanding. Changjiang Machinery's CHM‑SGT twin‑blade series synchronous dual‑drum sheeter performs remarkably well at slitting metallic cardboard, perfectly solving many challenges.
In the first production scene, we can clearly see the excellent performance of the CHM‑SGT twin‑blade series synchronous dual‑drum sheeter. It is equipped with an edge/line guiding control system for automatic edge alignment, plus a pneumatic slitting knife dust removal device. During operation, slitting + trimming splits one web into two – the efficient production state is highly impressive.
