The Production Process of Stone Paper in China

Producing stone paper is a unique process that combines advanced technology with eco-friendly principles. As a professional stone paper manufacturer in China, we have perfected this process to deliver high-quality, sustainable products.

The main ingredient in stone paper is calcium carbonate, which is ground into an ultra-fine powder. This powder is then mixed with a small percentage of high-density polyethylene (HDPE) resin, which acts as a binder. The mixture is heated and extruded into thin sheets, which are then stretched and cooled to form smooth, durable paper.

Unlike traditional paper manufacturing, our process does not require water, bleach, or harmful chemicals. This eliminates wastewater discharge and reduces the environmental impact significantly. The resulting product is not only eco-friendly but also stronger and more durable than wood pulp paper.

After extrusion, the stone paper can be cut, rolled, or coated depending on the intended application. Our factory offers customization in thickness, opacity, and surface finish to meet different market demands.

With its resistance to tearing, moisture, and insects, stone paper is an excellent choice for a variety of industries. From printing and packaging to stationery and outdoor signage, our products deliver exceptional performance and sustainability.
