How to Use This Table

• Find the core diameter: Choose from common sizes like 50mm, 76mm, or 100mm.
• Select the material thickness: Choose between 0.06 mm, 0.08 mm, or your specific thickness.
• Choose the number of layers: Select from standard values like 100, 200, or 300 layers.
• Find the estimated outside diameter: The value in mm represents the total roll diameter.

How is Outside Diameter Calculated?

The formula used: Outside Diameter=Core Diameter+(2×Material Thickness×Number of Layers)\text{Outside Diameter} = \text{Core Diameter} + (2 \times \text{Material Thickness} \times \text{Number of Layers})Outside Diameter=Core Diameter+(2×Material Thickness×Number of Layers)

Where:

• Core Diameter = The starting diameter of the empty roll core.
• Material Thickness = Thickness of each individual wrap layer.
• Number of Layers = The total number of times the material is wrapped.

Key Takeaways

• Thicker materials increase roll diameter faster.
• More layers add to the final roll diameter.
• Common core diameters include 50mm, 76mm, and 100mm.
