Durable Calcium Carbonate Paper Substrate
Durable calcium carbonate paper substrate is an eco-friendly, mineral-based paper material made primarily from calcium carbonate and a PE/HDPE-based polymer resin system.
As a high-performance alternative to both traditional wood-pulp paper and synthetic plastic films, this substrate offers a premium paper-like texture with built-in resistance to water, moisture, oil, and mechanical tearing. It is supplied in master rolls, custom rolls, or converted sheets tailored to your printing, converting, and end-use specifications.
Environmental & ESG Advantages
Tree-Free Production: Uses abundant calcium carbonate reserves, reducing reliance on wood pulp and deforestation.
Water-Free Process: The primary sheet-forming process requires zero industrial water, preventing wastewater generation.
Energy-Efficient: Lower energy consumption during manufacturing compared to conventional pulp processing.
Recyclable Material: Fully recyclable within compatible mineral-polymer waste streams.
Material & Structural Composition
Conventional Paper: Primarily cellulose fibers (susceptible to moisture absorption and tearing).
Stone Paper Substrate: Calcium carbonate (CaCO3) combined with a HDPE binder matrix (inherently waterproof, grease-proof, and tear-resistant).
Performance Highlights
Waterproof & Moisture-Proof: Will not warp, swell, or disintegrate upon contact with water, steam, or high humidity.
High Tear Resistance: Resists mechanical tearing during folding, die-cutting, high-speed feeding, and intense field handling.
Chemical & Oil Resistance: Impenetrable to oils, grease, and mild industrial chemicals.
Printable Surface: Engineered surface tension ensures sharp graphic detail and solid ink adhesion.

FAQ
Q: What is Durable Calcium Carbonate Paper Substrate made of?
A: It is a composite material composed primarily of calcium carbonate (CaCO3) mixed with a PE/HDPE polymer resin binder. It contains zero wood pulp and uses no water during core sheet extrusion.
Q: Can Stone Paper replace conventional synthetic paper or plastic films?
A: Yes. It serves as a cost-effective, eco-friendly alternative to traditional synthetic papers (such as PP or PET films), delivering equivalent waterproof and tear-resistant performance with a lower carbon footprint.
Q: Is this substrate compatible with standard commercial printing equipment?
A: It is compatible with Offset, UV, Flexo, and Digital printing technologies. Because surface absorption differs from traditional pulp paper, a preliminary trial run is recommended to optimize ink formulation and drying times.
Q: Can specifications like thickness, GSM, roll width, and sheet dimensions be customized?
A: Yes. Thickness, basis weight, roll width, core diameter, sheet size, and surface finish can all be engineered to meet your specific converting machinery requirements.
Q: What information and technical support are provided before bulk ordering?
A: We provide Technical Data Sheets (TDS), MSDS, compliance documentation, and physical sample kits so you can complete printing and converting trials prior to mass production.
