Triplex board is similar to duplex board but includes one additional layer. This extra layer improves the overall strength and quality of the material. This means the packaging made triplex board is also more durable and premium than duplex.
Just like duplex board, the triplex has a smooth outer surface that is very much suitable for printing. The inner layers are thicker, which helps the box feel more solid.

Because of the added layer, triplex board can handle more pressure. It does not bend as easily and gives better support and protection to the product packed inside.
The printing surface is also slightly better than that of duplex paperboard. Colors appear to be clearer, and the overall look feels more refined compared to lower-grade boards.
This capability and ability to be printed however a business wants make triplex board a good choice for packaging. This makes the packaging as well as the product look better at a glance but still stay within a reasonable budget.
