Duplex Board Weight Calculator
Duplex Board Weight Overview
Duplex board, a type of paperboard made from two layers, is commonly used in various applications due to its strength and versatility. Understanding its weight classifications is essential for selecting the right type for specific uses. The weight of duplex board is typically measured in grams per square meter (GSM) and can also be expressed in points (PT) or pounds (lbs).
Key Measurements
- GSM (Grams per Square Meter): A metric measurement indicating the weight of one square meter of paper.
- PT (Points): A measurement where 1 PT equals 0.001 inches in thickness.
- U.S. Basis Weight: Often used in the U.S., referring to the weight of a ream (500 sheets) of paper.
Duplex Board Weight Comparison Table
| Type of Duplex Board | GSM | Thickness (mm) | Common Uses |
|---|---|---|---|
| Light Weight Coated | 250 | 0.32 | Packaging, lightweight applications |
| Medium Weight Coated | 300 | 0.37-0.38 | General packaging, displays |
| Heavy Weight Coated | 350 | 0.44-0.45 | Sturdy packaging, boxes |
| Extra Heavy Coated | 400 | 0.50-0.51 | High-quality packaging, rigid boxes |
| Ultra Heavy Coated | 450 | 0.57-0.58 | Industrial use, heavy-duty boxes |
Additional Information
- Coating: Duplex boards can be coated for improved printability and water resistance, making them suitable for various products including food packaging and promotional materials.
- Environmental Impact: Many duplex boards are made from recycled materials and are compliant with food safety standards, making them an eco-friendly choice for packaging.
Understanding these specifications helps in selecting the appropriate duplex board for different applications, ensuring both functionality and quality in end products.
