What is a Corrugated Box Job Sheet?
Complete production document with Mixed Flute (B+C, A+B etc.) support
A Job Sheet is a standardized document used in corrugated box factories to communicate all production specifications. This updated version now supports Mixed Flute configurations — where different flute types (e.g., B Flute + C Flute) are used in the same box for optimum strength and print quality.
What is Mixed Flute?
A box made with two different flute types — e.g., B Flute (inner) for print quality and C Flute (outer) for cushioning. Each flute layer uses its own take-up factor for accurate GSM and weight calculation.
Why Different Factors?
Each flute type uses different paper length (take-up). A Flute = 1.55×, B Flute = 1.35×, C Flute = 1.45×, E Flute = 1.30×, F Flute = 1.25×. Mixed flute calculates each independently for accurate total GSM.
What's New in v2?
Each flute layer now has its own flute type selector. 5-Ply has 2 independent flute dropdowns. 7-Ply has 3 independent flute dropdowns. Single flute = same type for all (default). Mixed = different types.
Common Mixed Configs
B+C (5-Ply): Print outside + cushion inside. A+B (5-Ply): Heavy duty. B+B+B (7-Ply): High strength. C+B+C (7-Ply): Balanced. Each can now be configured independently per flute layer.

FREQUENTLY ASKED QUESTIONS
What is Mixed Flute and how is its weight calculated?
Mixed Flute means different flute types in the same box — e.g., 5-Ply with B Flute (1st) and C Flute (2nd). Total GSM = Top + (F1_GSM × F1_Factor) + Middle + (F2_GSM × F2_Factor) + Bottom. Each flute uses its own take-up factor, so weight is accurately calculated for any combination.
What are the Flute Take-up Factors?
A Flute = 1.55 (4.5mm thick, best cushioning), B Flute = 1.35 (3mm, best for printing), C Flute = 1.45 (3.5mm, medium), E Flute = 1.30 (1.5mm, retail boxes), F Flute = 1.25 (0.8mm, micro-flute). These factors represent how much extra paper length the fluting process uses compared to the liner.
What is the corrugated box weight formula?
CL (Cutting Length) = (L+W)×2 + 60mm. Sheet Area = CL × (W+H+30) ÷ 1,000,000 m². Weight per Box = Area × TotalGSM ÷ 1000 × 1.03 (includes 3% standard wastage factor). For mixed flute: TotalGSM = sum of all liner GSMs + sum of (each flute GSM × its own factor).
What does "Dual Sheet in Deckle" mean?
When (W+H+20)×2 is less than or equal to 1320mm, two boxes can be cut from a single deckle width. This significantly reduces paper wastage and is the most efficient way to run small boxes.
What is the difference between OD and ID dimensions?
OD (Outer Dimension) = External size of the finished box. ID (Inner Dimension) = Internal/inside measurement. The calculator automatically adds board thickness: 3-Ply adds +4mm L/W, +7mm H; 5-Ply adds +6mm L/W, +10mm H; 7-Ply adds +9mm L/W, +13mm H.
How is the deckle wastage percentage calculated?
Wastage % = ((Use Deckle − Required Deckle) ÷ Use Deckle) × 100. Less than 2% is excellent, 2–8% is acceptable, 8–15% is high, and above 15% means you should use a smaller deckle size.
