Paper Uncoated Super Calander Kraft, Color : White

Uncoated Super Calendered Kraft Paper (SC Kraft Paper) is a type of kraft paper that has undergone a calendering process to enhance its smoothness and finish. It is typically made from virgin wood pulp, which gives it strength, durability, and versatility for a wide range of uses. The uncoated nature of the paper means it retains its natural texture and absorbency.

1. Material Composition:

   • Made from virgin or recycled wood pulp.
   • Strong, durable, and tear-resistant due to the kraft pulping process.

2. Calendering Process:

   • After being manufactured, the paper goes through a calendering machine, where it is pressed between heated rollers. This process increases smoothness and density without adding a coating.

3. Surface Finish:

   • Smooth but uncoated: The paper has a slightly glossy finish due to calendering but does not have a coating layer like other types of paper (e.g., coated paper).
   • Natural texture: Retains a natural, rustic look and feel.

4. Color:

   • Typically a light brown to dark brown color depending on the pulp used and the production process.
   • Can be available in bleached (lighter color) or unbleached (darker color) variations.

5. Strength:

   • High tensile strength: It is resistant to tearing and has high durability, making it ideal for applications requiring rugged material.
   • Bursting strength: The paper can withstand a significant amount of pressure before tearing or bursting.

6. Weight & Thickness:

   • Available in a wide range of grammages (from 30 gsm to 250 gsm or more).
   • The thickness can vary depending on the weight of the paper.

7. Opacity:

   • Moderate opacity: The paper is somewhat opaque but may allow slight visibility through the paper depending on the weight.

8. Applications:

   • Packaging: Frequently used for kraft paper bags, envelopes, and wrapping.
   • Printing & labeling: Suitable for flexographic printing, but due to its uncoated nature, high-resolution printing may have a more textured finish.
   • Food packaging: Often used for food-grade packaging applications (with a natural appearance and safe for direct contact with food).
   • Envelopes and Mailing: Often used for premium envelopes, especially for industrial and high-end uses.

9. Environmental Impact:

   • Recyclable and biodegradable: SC kraft paper is environmentally friendly due to its natural composition, making it a sustainable choice for many industries.
   • Low environmental footprint: The uncoated nature of the paper contributes to a lower impact on the environment compared to highly processed papers.

• Strength & Durability: The paper is stronger than many other uncoated papers, making it ideal for packaging and industrial uses.
• Eco-friendly: Being recyclable and biodegradable, it is a more sustainable option compared to synthetic materials.
• Versatility: Can be used in a wide range of applications from food packaging to industrial uses, printing, and retail.
• Natural Look & Feel: Its rustic and natural appearance is preferred for certain branding and packaging needs.

• Limited Print Quality: Since it’s uncoated, the print quality may not be as sharp or vibrant as coated papers, though it’s still suitable for most industrial printing needs.
• Water Resistance: Although durable, it can absorb moisture, leading to a loss of strength in highly humid conditions unless treated for moisture resistance.
