Description of Duplex Board

Duplex board is a type of cardboard made from two layers of bleached chemical pulp, also known as white-lined chipboard. It is a popular material for packaging due to its strength, durability, and cost-effectiveness. Duplex board is often used for products that require a high level of protection, such as electronics, cosmetics, and food items.

The two layers of pulp in duplex board provide a smooth surface for printing, making it an ideal material for branding and marketing purposes. It can also be laminated with other materials such as plastic or aluminum foil to enhance its barrier properties.

There are two types of duplex board: coated and uncoated. Coated duplex board has a layer of clay or other coating material applied to one or both sides to improve its printing properties and enhance its appearance. Uncoated duplex board, on the other hand, has a natural matte surface that is suitable for products that do not require a glossy finish.

Duplex board is available in a range of thicknesses and can be customized to meet specific packaging needs. Its versatility, strength, and cost-effectiveness make it a popular choice for a wide range of packaging applications.

The thickness of the paperboard is typically described in millimeters or by gsm (grams per square meter). For example, 1.5mm equals 900gsm, 2mm equals 1200gsm, and 3mm equals 1800gsm.

Coated duplex cardboard is different from corrugated fiberboard. It is sturdy and thin, and more water-resistant, which makes it ideal for making boxes for a variety of small goods that require high-quality printability. Some examples of products made using coated duplex cardboard include Agarbatti boxes, pharmaceutical packaging, paper plates, cigarette packs, and various other packaging products.

There is another type of duplex boxboard that is relatively lightweight and is commonly used for making matchboxes, book covers, and greeting cards.

All the duplex cardboard is made from recycled material. For U.S and EU markets, we can offer FSC certified cardboard material, which is strictly followed the principle.

Duplex Board Colors

Duplex board comes in a variety of colors, making it a versatile material for packaging and display purposes. The most common colors are white, brown, and grey, but duplex board can also be produced in other colors to match the branding or design of a product.

White duplex board is a popular choice for packaging and displays because it provides a clean, crisp background that can enhance the appearance of products. Brown duplex board, on the other hand, has a more natural and rustic look that is well-suited for products with an organic or eco-friendly image. Grey duplex board is often used as a neutral background color that can complement a variety of product designs.

In addition to these standard colors, duplex board can also be produced in custom colors to match the branding or design of a product. This allows for greater flexibility in the design of packaging and displays, and can help products stand out on crowded store shelves.

It is worth noting that the color of duplex board can impact the printing process, as darker colors may require more ink to achieve the desired print quality. However, a skilled printing team can work with the chosen color to ensure that the final product meets the desired standards for both color and print quality.

In conclusion, the duplex board is quite similar to the CCNB paper, just a different thickness.

Applications of Duplex Board

The duplex board offers several advantages, including its rigidity, durability, and straightness. At Box Packaging Solution, we often use duplex boards to create luxury rigid gift boxes, such as rigid shoe boxes, garment boxes, and toy packaging. Its exceptional stiffness provides strong support for the box die-cutting process and produces high-quality results when laminated or hot stamped. Additionally, it is commonly used for making containers for wine and liquor packaging.

Uncoated duplex board is typically wrapped with art paper and specialty paper to create rigid boxes with fantastic artwork printing.

Duplex paperboard is an eco-friendly material made from 100% recycled paper. In the food industry, ordinary duplex cardboard is typically not made from recycled paper due to hygiene reasons. However, waste paper may be used if the paperboard is designated for other purposes.
