The Corrugated Board Weight Calculator estimates the total weight of corrugated cardboard based on its construction and specifications. It is widely used in packaging industries to determine the weight of boxes for material selection, logistics planning, and cost estimation. This tool provides quick and accurate calculations for single-wall, double-wall, or triple-wall boards.
Formula of Corrugated Board Weight Calculator
The weight of a corrugated board is calculated using the formula:
board_weight = [(linerboard_weight × number_of_liners) + (medium_weight × fluting_factor × number_of_mediums)] × board_area
Detailed Formula Components
- linerboard_weight:
The weight of the flat layers of paperboard (liner) in grams per square meter (gsm). - number_of_liners:
The total number of liner layers in the corrugated board:- Single-wall board: 2 liners
- Double-wall board: 3 liners
- Triple-wall board: 4 liners
- medium_weight:
The weight of the fluted (corrugated) paper per unit area, measured in gsm. - fluting_factor:
A factor that accounts for the extra surface area due to the corrugation of the medium. Common values:- B-flute: 1.15
- C-flute: 1.25
- E-flute: 1.50
- number_of_mediums:
The number of corrugated mediums in the board:- Single-wall board: 1 medium
- Double-wall board: 2 mediums
- Triple-wall board: 3 mediums
- board_area:
The total area of the board, typically measured in square meters (m²). - board_weight:
The final calculated weight of the corrugated board, expressed in grams (g) or kilograms (kg).
Pre-Calculated Table for Common Scenarios
| Linerboard Weight (gsm) | Medium Weight (gsm) | Fluting Factor | Number of Liners | Number of Mediums | Board Area (m²) | Board Weight (g) |
|---|---|---|---|---|---|---|
| 120 | 100 | 1.25 | 2 | 1 | 1 | 325 |
| 150 | 120 | 1.15 | 3 | 2 | 1.5 | 885 |
| 200 | 150 | 1.25 | 4 | 3 | 2 | 2200 |
| 100 | 80 | 1.50 | 2 | 1 | 0.5 | 112.5 |
Example Corrugated Board Weight Calculator
Scenario:
You need to calculate the weight of a single-wall corrugated board with the following specifications:
- Linerboard weight = 120 gsm
- Medium weight = 100 gsm
- Fluting factor = 1.25 (C-flute)
- Number of liners = 2
- Number of mediums = 1
- Board area = 2 square meters
Step-by-Step Calculation:
- Calculate Liner Contribution:
liner_contribution = linerboard_weight × number_of_liners
liner_contribution = 120 × 2 = 240 gsm - Calculate Medium Contribution:
medium_contribution = medium_weight × fluting_factor × number_of_mediums
medium_contribution = 100 × 1.25 × 1 = 125 gsm - Total Weight per Square Meter:
total_weight_per_m² = liner_contribution + medium_contribution
total_weight_per_m² = 240 + 125 = 365 gsm - Total Board Weight:
board_weight = total_weight_per_m² × board_area
board_weight = 365 × 2 = 730 grams
Result:
The weight of the corrugated board is 730 grams.
Most Common FAQs
Calculating the weight helps in selecting materials that meet the packaging strength and cost requirements while optimizing logistics and transportation costs.
Yes, the formula is applicable for single-wall, double-wall, and triple-wall boards, provided the specifications (liner weight, medium weight, and fluting factor) are known.
The fluting factor accounts for the additional surface area introduced by the corrugation in the medium. Different flute types (B, C, E) have different factors that impact the weight calculation.
