Understanding Decorative Paper Grammage: 60g, 65g, 70g, 80g and 85g

In decorative paper production, grammage is one of the basic specifications that customers often need to consider. It affects not only the weight of the paper itself, but also printing performance, opacity, impregnation behavior, cost and final surface effect.

Grammage usually refers to the weight of paper per square meter, expressed as g/m². For example, 70g decorative paper means that one square meter of the base paper weighs about 70 grams before impregnation and pressing. In the decorative paper industry, common grammage options include 60g, 65g, 70g, 80g and 85g, depending on product positioning and application requirements.

It is important to understand that grammage is not simply a quality grade. A higher grammage does not automatically mean a better product, and a lower grammage does not necessarily mean poor quality. The right choice depends on the required surface effect, substrate color, printing design, resin impregnation process, pressing condition and cost target.

60g Decorative Paper

60g decorative paper is a lighter option. It can be suitable for cost-sensitive products or applications where the surface design does not require very strong covering power. Because the paper is lighter, it may have good flexibility and can be easier to handle in some production conditions.

However, 60g paper usually has weaker opacity compared with higher grammage options. If the substrate color is dark or uneven, the base material may influence the final surface tone. It may also require more careful control during printing and impregnation to avoid color instability or insufficient visual depth.

65g Decorative Paper

65g decorative paper is slightly stronger than 60g and can provide a better balance between cost and performance. It is often used when customers want a relatively economical solution but still need improved print stability and better surface coverage.

Compared with 60g, 65g can offer better color expression and opacity, while still maintaining cost efficiency. Its limitation is that it may still not be the best choice for applications that require strong covering power, complex color layering or very strict surface consistency.

70g Decorative Paper

70g decorative paper is a widely used and balanced option. It usually provides a good combination of printability, opacity, impregnation performance and cost control. For many wood grain, solid color and standard decorative surface designs, 70g can meet common production needs.

This grammage is often considered a practical middle choice. It can support stable printing, clearer pattern performance and better surface consistency than lighter papers. At the same time, it does not bring as much cost or impregnation pressure as heavier papers.

80g Decorative Paper

80g decorative paper is often used for higher-end designs or applications that require stronger opacity and richer visual performance. Because the paper is heavier, it can help improve covering power and support a more stable visual layer when matched with the right base paper formulation and printing process.

The advantage of 80g paper is better visual depth and stronger surface presence. It can also work well with EIR synchronized embossing when the product needs a stronger real wood effect. With better coverage and a richer visual layer, 80g paper can help support deeper grain structures, cathedral grain, wood pores and tactile texture details.

However, it may also bring higher material cost and require more careful control during impregnation. Heavier paper can absorb more resin, and the production process may need to be adjusted to maintain proper resin content, drying stability and pressing performance.

85g Decorative Paper

85g decorative paper is a heavier option and is usually selected for products that require stronger coverage, richer color depth or a more premium decorative effect. It can be helpful when the design contains complex wood structures, strong visual layering or when the final product requires a stronger surface presence.

In EIR applications, 85g paper may further enhance the sense of depth and real wood feeling when it is properly matched with the printed design and synchronized steel plate. It can support stronger texture expression and make the surface appear more solid and layered.

At the same time, 85g is not suitable for every product. Its cost is higher, and impregnation control becomes more important. If resin absorption, drying and pressing are not properly managed, heavier paper may create production challenges such as uneven resin distribution, curling, brittleness or bonding issues. In some production systems, heavier paper may also affect paper yield or output efficiency, so it needs to be evaluated together with the production process.

How to Choose the Right Grammage

Choosing decorative paper grammage should be based on the full product system, not only the paper itself. Customers should consider the following factors:

• Substrate color and covering requirement

• Base paper opacity and formulation

• Wood grain or surface design complexity

• Light or dark color tone

• Printing ink coverage

• Resin impregnation process

• Pressing condition

• EIR synchronized embossing requirement

• Final application and cost target

For example, a light oak design on a stable substrate may not require very heavy paper. But for dark walnut, smoked wood, high-contrast patterns or applications where the substrate color needs stronger coverage, customers may need decorative paper with better opacity and color stability. Higher grammage can sometimes be one way to support this requirement, but it should be considered together with base paper formulation, printing ink coverage, impregnation behavior and the final pressing process.

For EIR synchronized embossing products, grammage selection becomes even more important. Higher grammage decorative paper can sometimes support a stronger real wood effect by providing better coverage, richer visual depth and a more solid surface layer. When matched with deep embossing, cathedral grain, wood pores and synchronized steel plates, heavier paper may help the final surface look and feel closer to natural wood.

At the same time, heavier grammage also has its limitations. It may absorb more resin and require more careful impregnation, drying and pressing control. In some cases, heavier paper can also affect paper yield or output efficiency. Therefore, the right grammage should be selected based on both visual performance and production stability.

In short, decorative paper grammage is about balance. Lower grammage can support cost efficiency and flexibility, while higher grammage can improve covering power and visual richness. The best choice depends on the final product requirement and production process.
