 Key Features & Capabilities

1. Carton Box Cost Calculator (Roll-Based & Paper-Based)
Flexible Dimensions Input: Enter Length, Width, and Height in Inches, CM, or MM with instant real-time unit conversion.
Automatic Cut Sheet & Deckle Size: Instant cut length and roll width calculations with manual cut size override support.
Multi-Ply Structure: Full support for 3-Ply, 5-Ply, and 7-Ply corrugated board specifications.
Dual Costing Engines:
Roll-Based Mode: Calculate costs from corrugated roll rates, center liner paper GSM, silicate glue, making labor, carriage, wastage %, and target profit margin.
Paper-Based / Plant PSI Mode: Detailed itemized breakdown per paper layer (Kraft, Testliner, Fluting C-factors), plant PSI rates, silicate, and printing.

2. Stiffener, Partition & Pad Costing
Precision Crease Layout: Input Length (L1), Crease Gap (G), Length (L2), and Width (W).
Master Sheet Optimization: Auto-calculates the exact number of stiffeners cut per master corrugated sheet.
Material Requirement Metrics: Calculates total master sheets and roll requirements instantly.

3. Corrugated Roll Cost & Reel GSM Engine
Dual Mode Calculation: Estimate roll cost per inch using Weight/Residual mode or GSM mode.
Live Reel GSM Formula: Automatic calculation of actual paper reel GSM from roll weight, residual weight, and quantity: $$\text{Reel GSM} = \frac{(\text{Net Weight}) \times 1,550,000}{2400 \times \text{Qty}}$$
Flute Reel GSM: Takes into account fluting take-up factors for 2-ply corrugated rolls.

4. Paper Reel Weight, Diameter & Meter Length
Paper Type Profiles: Built-in support for Fluting, Testliner, Kraftliner, High-Performance (HP), and Duplex Board.
Caliper & Micron Precision: Calculates paper caliper in microns based on paper substance (GSM).
Loose Winding Factor: Adjustable slack winding multiplier (+8% effective caliper) for accurate physical reel sizing.
Meter Length & Weight: Instantly determine total paper meters on a reel from outer diameter, roll width, and 4-inch core size.

5. Reel Slitting & Combination Optimizer
Deckle Utilization: Input machine decal roll width to find optimal slitting combinations.
Zero Trim Waste: Algorithmically generates even and odd slit width combinations to eliminate expensive paper wastage.

6. Quick Packaging Utilities
GSM Calculator: Calculate paper substance (g/m²) from sample sheet weight and dimensions.
Paper Weight Calculator: Determine total paper weight in kg and total paper cost.
Quantity Calculator: Calculate exact sheet or box count from total paper weight and GSM.

7. Professional Customer Quotation Generator (PDF)
Branded Quotations: Create itemized quotations complete with your company logo, NTN/Tax ID, address, terms & conditions, and bank details.
Multi-Currency Support: Full support for PKR (Rs.), USD ($), EUR (€), GBP (£), AED, INR (₹), SAR, and more.
PDF Export & Sharing: Generate high-definition PDF quotes and share via WhatsApp, Email, or Print directly from iOS.

8. Saved Costing & History Vault
Local Storage Vault: Save carton and stiffener costing records for quick retrieval.
Advanced Filtering: Filter by Roll Costing, Paper-Manual, Paper-Plant, or Date Ranges (Today, This Week, This Month, Custom).
