Uncoated MG Kraft Super Calander 120GSM

Uncoated MG Kraft Super Calendered (SC) paper, with a basis weight of 120 GSM (Grams per Square Meter), is typically used for applications like packaging, printing, and labels. Here's a detailed specification description:

1. Basis Weight:

   • 120 GSM – This indicates the mass per unit area of the paper, which in this case is 120 grams per square meter.

2. Caliper (Thickness):

   • Typically 0.15 mm – 0.18 mm (depending on specific manufacturing standards). Caliper refers to the thickness of the paper.

3. Bulk:

   • 1.20 – 1.50 cm³/g – Bulk is the volume per unit weight of paper, which directly influences the stiffness of the sheet.

4. Brightness:

   • 75% – 85% ISO – The brightness of the paper indicates how much light it reflects. It is typically lower in uncoated papers but provides a natural, earthy look.

5. Whiteness:

   • Natural white – Since the paper is uncoated, it will have a slightly off-white or natural color with more texture and absorbency compared to coated varieties.

6. Surface Properties:

   • Uncoated – The paper will have a slightly rough texture that allows for better ink absorption.
   • Super Calendered – The paper has been mechanically processed to achieve smoothness and improved finish without coating. This enhances printability and surface quality.

7. Opacity:

   • Around 85% – 90% – Opacity refers to how much light passes through the paper. Higher opacity means it is less transparent.

8. Moisture Content:

   • 5% – 7% – The paper’s moisture content can vary but typically falls within this range, impacting its stiffness and print quality.

1. Tensile Strength:

   • Approximately 30 – 40 N/mm² (M.D.), 25 – 35 N/mm² (C.D.) – This refers to the paper's resistance to breaking under tension, both in the machine direction (M.D.) and cross-direction (C.D.).

2. Tear Resistance:

   • 20 – 30 mN – Tear resistance indicates how well the paper resists tearing when a force is applied.

3. Bursting Strength:

   • 2.5 – 3.5 kPa – The ability of the paper to withstand a uniform pressure applied to its surface.

4. Stiffness:
