Stone Paper Extrusion Line Features
1. Highly Compatible & Customizable
It can be adapted to single/twin screw extruders, and can produce 3-layer PP/PE eco-friendly stone paper and wallpaper. It can process PVC/PE/PP materials as well. The modular design has 5 core modules, and the molds and components can be freely matched to meet various production needs.
2. Professional Molding & High-End Components
The customized molding and stretching units can ensure good plasticization effect of the materials, high tensile strength of the finished products, and a smooth surface. Combined with special mixing screw, impurity-filtering screen changer, precise T-die, and 3-roll calendar, these high-quality components ensure stable production and high-quality products.
3. Efficient Production & Cost Savings
The process is simple, with high output, low energy consumption, and no need for pre-granulation; multi-component precision scales can start directly, and the automatic winding machine can also reduce labor costs and lower production investment.
4. More Environmentally Friendly Production for a More Sustainable Future
Production does not use plant fibers, which can save wood, and does not use irritating chemicals such as strong acids, strong alkalis, and bleaching agents; there is no wastewater, residue, or harmful emissions throughout the process, fully meeting green production standards, and being particularly friendly to the environment.
5. Intelligent Operation, Durable & Safe

Product Features
1. Excellent Printing Quality, Good Texture
It can achieve fine and high-definition printing. Ordinary ink can be used, and the cost is only 1/3 of traditional synthetic paper; the texture is soft, and the folding performance is particularly good, stronger than natural paper and traditional synthetic paper.
2. Full Protection Performance
Waterproof, moisture-proof, pest-proof, mold-proof, oil-proof, static-proof, wear-resistant, heat-resistant, it won’t deform even at 100℃; good light resistance and light transmission, stable size, and not prone to deformation.
3. Environmentally Friendly & Safe
Non-toxic, odorless, pollution-free. It doesn’t contain plant fibers and can save wood; production does not use irritating chemicals such as strong acids, strong alkalis, and bleaching agents. There is no wastewater, residue, or harmful substances discharged; after disposal, it can be controllably degraded into powder, without causing secondary pollution.
4. Strong and Durable, High Cost-Effectiveness
Tough and resistant to tearing and folding, with high strength and durability; low production cost, compared with traditional paper, it can save forest resources. Compared with plastic packaging, it can save 2.3 tons of petroleum per ton. The production is also particularly water-saving. It is suitable for areas with less wood.
5. Wide Application Scenarios, High Production Efficiency
It can replace traditional functional/ professional paper and also replace most plastic packaging. It can meet various needs; the production process is simple, with high output, low energy consumption. The leftover materials from production can be recycled or degraded, and the resource utilization rate is particularly high.
