Eco Friendly Mineral Paper Substrates
Designed as a durable, moisture-resistant, and tear-resistant alternative to conventional wood-pulp paper and synthetic films, our Mineral Paper Substrates (commonly known as Stone Paper) deliver exceptional surface consistency and mechanical stability across high-demanding converting processes.
Primary Application Domains
Commercial Printing: High-durability maps, field manuals, waterproof menus, outdoor posters, and brochures.
Packaging Solutions: Product sleeves, retail tags, luxury bags, and moisture-exposed packaging components.
Labels & Tags: Industrial hangtags, self-adhesive face stocks, and logistics labels.
Publishing & Stationery: Heavy-duty notebook covers, waterproof journals, calendars, and educational materials.
Specialty Products: Outdoor operational guides, play cards, and moisture-resistant collateral.
Material & Structure
Unlike standard cellulose papers that rely on plant fibers, Mineral Paper utilizes a non-fibrous, mineral-dense composite network.
Core Formulation:
- Calcium Carbonate (CaCO3): ~70%–80% (Provides opacity, brightness, surface smoothness, and dimensional density).
- Polymer Resin (HDPE Matrix): ~20%–30% (Acts as a durable binder, delivering tear resistance and water barrier properties).
- Functional Additives: Surface tension modifiers, UV stabilizers, and specialized printable coatings.
Key Performance Advantages
Water & Moisture Immunity
The continuous polymer matrix makes the material naturally hydrophobic. It does not swell, warp, disintegrate, or lose structural integrity when exposed to water, liquid splashes, high humidity, or condensation.
Superior Tear & Handling Resistance
The multi-directional composite structure exhibits high resistance to propagation tearing, edge wear, and repeated folding. Ideal for items subjected to harsh handling or outdoor environments.
Ultra-Smooth Printable Surface
Featuring an exceptionally smooth, non-porous finish, the substrate requires less ink absorption while enabling high-definition color reproduction, sharp text clarity, and strong ink adhesion.
High Dimensional Stability
Because it contains no organic wood fibers, the material does not expand or contract drastically in response to ambient humidity changes, minimizing register misalignment during multi-pass printing.

Printing & Processing Guidelines
Printing Compatibility
- UV / LED Offset Printing: Excellent ink curing, color pop, and fast throughput.
- Flexographic Printing: Ideal for long-run packaging and pressure-sensitive labels (UV or specialized quick-dry inks recommended).
- Screen Printing: Exceptional color opacity for heavy-duty signage and specialty graphics.
- Digital Printing: Compatible with UV-curable digital inkjets and select low-temperature digital presses.
Pre-Production Trial Recommendation
- Prior to bulk commercial runs, we strongly advise conducting an on-site printing trial to verify:
- Sheet feeding stability and static control
- Registration precision under tension
- Ink adhesion (Tape Test verification) and drying time
- Rub/Scuff resistance and post-press creasing performance
Manufacturing & Quality Control
Thickness Tolerance: On-line gauge monitoring ensures thickness variance within ±3%.
Mechanical Testing: Verified per batch using Elmendorf Tear and Tensile Strength testers.
Surface Dyne Monitoring: Ensures consistent printability across the entire web length.
Regulatory Compliance & Certification
ISO Quality Management: ISO 9001:2015 Manufacturing Standards.
Environmental & Chemical Safety: REACH Regulation compliant; RoHS Directive compliant (Free of heavy metals and hazardous phthalates).
Food Contact Grades: Select formulations compliant with FDA 21 CFR standards for indirect food packaging.
Third-Party Testing: Full SGS / Intertek test reports available upon qualification.

FAQ
Q: What are the main ingredients of Mineral Paper (Stone Paper)?
A: Mineral paper is a mineral-polymer composite substrate consisting primarily of high-purity Calcium Carbonate (CaCO3, ~70-80%) bound together with non-toxic High-Density Polyethylene resin (HDPE, ~20-30%).
Q: Is Mineral Paper completely waterproof?
A: Yes. The material is inherently waterproof and impervious to liquid absorption. It retains its full structural strength, dimension, and shape even when fully submerged in water or exposed to high-humidity environments.
Q: Can I print on Mineral Paper using standard offset presses?
A: Yes, using appropriate inks. Offset printing with oxidation-drying inks, UV-curable inks, or LED-UV inks yields excellent results. Standard water-based or oil-based inks requiring deep fiber penetration may exhibit longer drying times. A pre-production trial is always recommended.
Q: How does Mineral Paper compare to standard plastic films (e.g., PP or PVC)?
A: Mineral Paper provides a smooth, matte, luxury paper-like feel without the static charge, high elasticity, or harsh synthetic feel typical of standard rigid plastic films. It is also tree-free and degrades naturally under continuous UV exposure without releasing toxic gases.
Q: What is the typical lead time and MOQ for custom production orders?
A: Standard sample kits and stock roll grades ship within 3–5 business days. Custom thickness, specific GSM formulations, or specialized roll/sheet dimensions typically carry a 2–3 week lead time depending on order quantity and factory scheduling.
