6 Types of Triplex Paper Board You Should Know About
Triplex paper board is a three-layered paperboard commonly used in packaging, printing, and display applications. With a smooth, printable surface and a sturdy structure, it offers both visual appeal and functional strength. What sets triplex board apart is the layered construction: a high-quality coated white surface layer, a middle layer usually made of recycled paper pulp, and a bottom layer that varies depending on the grade and application.
Triplex board manufacturers produce several types of this material to suit different commercial and industrial needs. Below are six common types of triplex paper board you should be familiar with:
The coating on the top and back layers improves printability, allowing for vibrant colors and sharp text. It's also great for embossing and foil stamping. If you're aiming for an upscale look without going overboard on costs, white back triplex is a solid choice.
2. Grey Back Triplex Board
Grey back triplex board is similar to white back but with a significant cost-saving twist: the reverse side is grey instead of white. This type maintains a coated white front surface, ideal for branding and product information, but the grey back is more utilitarian.
Because of the lower production cost, grey back triplex is widely used in packaging for electronics, toys, and food products where the back side isn't meant to be seen. It's a go-to material when function outweighs appearance.
3. Kraft Back Triplex Board
This version combines a white coated front for printing with a kraft paper back, giving it a natural, eco-friendly appearance. The brown kraft layer enhances the board's strength and makes it more resistant to moisture, making it suitable for heavier or more rugged packaging needs.
Kraft back triplex boards are popular in agricultural and industrial sectors, where durability is key. Brands that focus on sustainability also prefer this option for its earthy look and recycled content.
4. Metallic Coated Triplex Board
For packaging that needs to stand out on shelves, metallic coated triplex board offers a unique finish. This board features a high-gloss, metallic coating on the top layer, giving it a reflective, eye-catching look.
Common in luxury packaging, gift boxes, and promotional materials, this board type supports specialty printing techniques. It pairs well with UV coating, embossing, and hot foil stamping. While it’s more expensive, the visual impact can be worth it in competitive retail environments.
Used in the packaging of items like frozen foods, bakery goods, and ready meals, this board type is grease-resistant and offers good printability. Some food-grade boards are also biodegradable, aligning with growing consumer demand for sustainable packaging options.
While technically a duplex board, some high-end coated duplex boards incorporate a triplex-like structure, offering the strength and print quality of traditional triplex board but at a slightly lower weight and cost.
These hybrid boards are great for medium-duty packaging that still needs visual appeal. Applications include beverage carriers, household goods, and small electronics. Triplex board manufacturers sometimes market these as "economic alternatives" to full triplex boards.
Choosing the Right Triplex Paper
Selecting the right triplex board depends on your application. If you need high-end graphics and consistency, go for white back. For cost-efficiency without compromising printability, grey back works well. Kraft and food-grade options serve specialized needs in industrial and food sectors.
It’s also essential to consider factors like thickness (caliper), grammage, print compatibility, and environmental impact. Triplex paper is recyclable, but the coatings and materials used in some types may affect compostability or biodegradability.
If sustainability is a priority, check for certifications like FSC (Forest Stewardship Council) or inquire if the materials are from post-consumer recycled content. Many triplex board manufacturers now offer eco-friendly variants to meet the growing demand.
Next time you’re sourcing materials, knowing these six types can help you make smarter, more informed decisions. And whether you're working with luxury branding or mass-market packaging, choosing the right triplex board can elevate both the look and performance of your product. Don’t underestimate the impact of this seemingly simple material—triplex paper can make a big difference.

5. Food Grade Triplex Board
Food grade triplex boards are made with hygiene and safety in mind. These boards are manufactured to meet food safety standards and are suitable for direct or indirect contact with food products. They often feature a polyethylene (PE) coating to enhance moisture resistance.Used in the packaging of items like frozen foods, bakery goods, and ready meals, this board type is grease-resistant and offers good printability. Some food-grade boards are also biodegradable, aligning with growing consumer demand for sustainable packaging options.
