The 5 Core Sections of an Industrial Tech Pack
| Section | Contents | Critical Manufacturing Function |
|---|---|---|
| 1. Technical Sketch & Callouts | Front, back, and interior vector line drawings with detail zoom boxes. | Specifies seam construction (e.g. flatlock, coverstitch), topstitching gauge, and pocket placements. |
| 2. Bill of Materials (BOM) | Itemized table of shell fabrics, linings, interlinings, threads, buttons, and zippers. | Enables accurate fabric consumption calculations and early procurement of trims. |
| 3. Points of Measure (POM) | Comprehensive measurement chart with precise step-by-step measuring guides. | Establishes golden sample evaluation metrics and factory floor QA tolerances. |
| 4. Grading Rules Table | Mathematical grade increments for XS, S, M, L, XL, 2XL across all POMs. | Guides digital pattern cutting without distorting the intended garment silhouette. |
| 5. Packaging & Labeling Spec | Main brand label, care/content label, hangtag placement, folding, and carton specs. | Ensures customs compliance, barcode scannability, and retail-ready warehouse handling. |
