“GSM means Grams per Square Meter, and higher GSM means better quality. Corrugated cardboard GSM calculates the total number of each layer paper GSM. For example, a piece of corrugated cardboard made from 3 layer B flute, 170gsm/190gsm/200gsm, then the corrugated cardboard GSM is near 560gsm. (Ignore the fluted layer more than it’s paper gsm after get corrugated) “

Need the whole printed surface seems gloss or matt, and protect the printing ink. After all, it will make a perfect touch feel. Corrugated fiberboard boxes are examples of laminated structures, where an inner core provides rigidity and strength, and the outer layers provide a smooth surface. Laminating paper products, such as photographs, can prevent them from becoming creased, faded, water damaged, wrinkled, stained, smudged, abraded, or marked by grease or fingerprints.

Photo identification cards and credit cards are almost always laminated with plastic film. Also, lamination is needed for further finish steps like UV varnishing, spot UV, hot foil stamping, as it is a good temper material to bear all kinds of heat and handling. To conclude, it is good to choose lamination for your corrugated packaging boxes when you have the below requests:

  • Anti-Scratch.

If your package needs somewhere to stand out of the printing, then spot UV is the right solution. It is always being used for LOGO, cartoons, text, and so on. It is being proceeded after offset printing and surface finish (glossy or matt varnishing and lamination).

Hot foil stamping is a specialty printing process that applies heat, pressure, and metal dies, and foil film to the printed and finished CCNB, kraft paper, art paper, and virgin paperboard. The foil comes in rolls in a wide assortment of colors, finishes, and optical effects. Metallic foil is most commonly seen today- particularly gold foil, silver foil, copper foil, and holographic metallic foils, and available colors could be chosen from our color chart.



Embossing and debossing are the processes of creating either raised or recessed designs in paper cardboard and other materials. An embossed pattern is raised against the background. Meanwhile, a debossed pattern is hollow into the surface of the paper cardboard.

    High-density fiberboard/Medium-density fiberboard, used for a heavy-duty gift box for heavy items. For example, an HDF-made gift box for tooling.


The different paper material has a different way of using, but they also can be laminated with each other to get new material. Such as two pieces 250gsm virgin paperboard laminated, then 500gsm virgin paperboard come out.
