Basis Weight Formula:
| From: | To: |
Basis weight is a measurement used in the paper and packaging industry to express the weight per unit area of a material. For SBS (Solid Bleached Sulfate) board, it indicates the weight in pounds per square foot of the board material.
The calculator uses the basis weight formula:
Where:
Explanation: The formula calculates the weight density of SBS board by dividing the total weight by the total area covered.
Details: Basis weight is crucial for quality control, material specification, and cost calculation in packaging manufacturing. It helps determine the thickness, durability, and performance characteristics of SBS board.
Tips: Enter weight in pounds and area in square feet. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is SBS board used for?
A: SBS (Solid Bleached Sulfate) board is a premium paperboard commonly used for high-quality packaging, cosmetic boxes, pharmaceutical packaging, and food containers.
Q2: What are typical basis weight values for SBS board?
A: SBS board typically ranges from 14 pt to 24 pt thickness, with basis weights varying from approximately 0.035 to 0.060 lb/sq ft depending on the specific grade and application.
Q3: How does basis weight affect packaging performance?
A: Higher basis weight generally indicates thicker, more rigid board with better durability and protection capabilities, but also increases material costs.
Q4: Can this calculator be used for other materials?
A: While designed for SBS board, the basic formula can be applied to any material where weight per unit area needs to be calculated, though specific industry standards may vary.
Q5: How accurate should my measurements be?
A: For precise results, use calibrated scales for weight measurement and accurate dimensional measurements for area calculation. Even small errors can affect the basis weight calculation significantly.
