Knowing its features and how it is made helps you pick the best material for your needs.
Grey board uses only recycled paper fibers. This makes it strong and good for the environment.
Pick the right thickness for your project. Thick boards are best for packaging. Thin boards work well for crafts.
Grey board can be used in many ways. It is used for packaging, bookbinding, arts and crafts, and in factories.
Using grey board helps nature. It saves trees, water, and oil. You can recycle it after you use it.
You can add coatings for more protection. Coatings help with water resistance and make the surface smoother.
You will notice that grey board stands out because of its thickness and solid feel. The thickness range gives you many choices for different projects. Here is a table showing the typical thickness options you can find:
| Thickness Range (mm) |
|---|
| 0.3 |
| 0.35 |
| 1.5 |
| 1.7 |
| 1.9 |
| 2 |
| 2.5 |
| 3 |
| 4 |
You can select a thickness that matches your needs. If you want a sturdy box, you might choose a thicker board. For crafts, a thinner sheet works well. The density of grey board also affects its quality. You can compare it with other paperboard materials in the table below:
| Material | Weight (GSM) | Density Comparison |
|---|---|---|
| Grey Hard Paperboard | 600 – 2000 | Denser than grey board paper |
| Grey Board Paper | 250 – 600 | Less dense than grey hard paperboard |
A denser board gives you more strength and better quality. You can rely on grey board for projects that need a tough and stable base.
Grey board offers you high quality in many ways. You can count on its strength and durability for packaging, book covers, and displays. The board resists bending and tearing, so your products stay safe. You can see how tensile strength varies by model in the table below:
| Model | Tensile Strength |
|---|---|
| Base Model | 2.5 N/m |
| Advanced Model | 3.0 N/m (+20%) |
| Pro Model | 4.0 N/m (+60%) |
If you need extra quality, you can choose a model with higher tensile strength. Additives can improve the board’s water resistance or surface smoothness. These changes help you get the right quality for your project. You can cut, stamp, ink, or paint grey board easily. This flexibility lets you use it for many creative and industrial tasks.
Tip: When you select grey board, check the thickness and tensile strength to match your project’s needs. Higher quality means better results.
Grey board is an eco-friendly material. You help the planet when you choose it. The board uses 100% recycled paper pulp. You can recycle it again after use. It is biodegradable, so it breaks down naturally. Here are the main environmental benefits:
Grey board is composed of 100% recycled paper pulp.
It is biodegradable.
It is recyclable.
You save energy by using grey board. Recycled boards use a third less energy than boards made from new fibers. This makes grey board an eco-friendly choice for packaging and crafts. You support a cleaner environment and reduce waste when you pick this material.
Grey board is made from recycled fibers. Most fibers come from waste paper. Old newspapers, cardboard, and packaging are used. This makes the material 100% recycled. Using these sources helps the environment. Grey chip board uses similar recycled paperboard. These sources help keep things sustainable.
Note: Using recycled fibers cuts down on waste and saves resources. Choosing this material is good for the planet.
The raw material is broken down into pulp. Mechanical or chemical pulping methods are used. Here are the main steps:
The material is pulped and turned into fibers.
The pulp is cleaned to remove ink and glue.
The clean pulp is spread on a wire mesh to form a sheet.
The wet sheet is pressed and dried with rollers and heat.
A coating may be added to make it stronger and easier to print on.
The finished grey board is cut and packed for use.
Grey board’s pulping process is not the same as other paperboards. Wood chips are steamed, heated, and cooked in digesters. Chemicals are used to make the pulp stronger and more flexible. These chemicals are then washed and reused. This process gives grey board its special strength.
The material is shaped by pressing it very hard. Heavy woodworking clamps press with about 1540 pounds of force. Vacuum bags can press with 13 to 14 psi. At sea level, air pressure is 1 atm or 14.7 psi. This pressure can press veneer layers.
Pressing temperature and time are controlled for the right thickness and strength. The table below shows how pressing changes the final product:
| Pressing Temperature (°C) | Pressing Time (min) | Resulting Thickness (mm) | Observations |
|---|---|---|---|
| 20-60 | Various | Not compressed | Loss of cohesion |
| 80 | 6 | Some binding | Insufficient stability |
| 120 | 0.5 | Some binding | Insufficient stability |
| 160 | Various | Firm, stiff, rigid | Stable boards obtained |
Higher temperatures and the right timing make a firm and stable board. Flexural strength goes up with lower thickness and higher density. Boards that are 5 mm thick reach a flexural strength of 10.06 N mm−2. This is almost as strong as the standard of 11.5 N mm−2 for boards between 3–6 mm.
Tip: For a strong and stable board, watch the pressing temperature and time.
The material is finished with treatments to make it better. You can pick from these options:
Transparent stains keep out moisture and let the board turn grey.
Semi-transparent stains show off the grain and protect well.
Solid-color stains give the most protection and let you pick the color.
Waxing makes the surface smooth and keeps out water and dirt.
Coating gives a nice finish and makes the board last longer. Water-based paints are a green choice.
| Treatment Type | Description |
|---|---|
| Transparent Stains | Changes the look a little, keeps out water, lets the board turn grey over time. |
| Semi-transparent Stains | Shows off the natural look, protects well, needs less redoing. |
| Solid-colour Stains | Gives the most protection, lets you pick the color, but hides some of the natural look. |
| Waxing | Adds a protective layer, keeps out water, dirt, and wear. |
| Coating | Makes the board look good, last longer, and water-based paints are better for the environment. |
Additives are also used when making the board. Urea formaldehyde is an adhesive. It helps the board stay strong and stiff. These finishing steps make grey board and recycled paperboard better for many uses.
Callout: The right finishing treatment makes your material last longer and look better.
