How to Create a Tech Pack for Custom T-Shirt & Polo Manufacturing (Free Factory Template)

For independent apparel designers, D2C brand founders, and corporate merchandise managers, turning a creative concept into a manufactured garment can feel like translating across two different languages. You imagine a sleek, oversized drop-shoulder polo; the factory produces a boxy dad shirt. Why do communication breakdowns happen?

In 95% of cases, the missing link is a professional Apparel Tech Pack (Technical Package). At Polos Inc in Tirupur, a tech pack serves as the legal blueprint and master recipe for your garments. Below, our pattern masters and sample room coordinators walk you through the essential components of a production-ready apparel tech pack.

What is a Tech Pack in Garment Manufacturing?

A tech pack is a comprehensive multi-page document created by a designer or technical pattern maker that instructs the manufacturing factory on every single specification required to produce the garment. Think of it as an architectural blueprint for clothing.

Without a tech pack, factories are forced to guess collar heights, stitch densities, tolerance allowances, and label placement. With a tech pack, sampling revisions decrease from 4–5 iterations down to a single first-round approval.

The 6 Vital Sections Every Tech Pack Must Contain

1. Cover Sheet & Flat Technical Sketches

The first page contains 2D black-and-white vector flat sketches of the garment (Front, Back, and Side views) drawn strictly to scale without shadows or fashion model styling. This sheet identifies:

• Style Name and Style Number (e.g., PI-2026-POLO-04)
• Target Season (e.g., Autumn/Winter 2026)
• Product Category (e.g., Men’s Classic Pique Polo)
• Key Construction Details (e.g., 2-button placket, side vents with herringbone tape)

2. Bill of Materials (BOM)

The BOM lists every physical component required to construct one unit of the garment:

3. Points of Measure (POM) & Grading Spec Sheet

The measurement sheet dictates the exact dimensions in centimeters or inches across all production sizes (XS to 3XL). Each measurement point must specify an acceptable factory tolerance (e.g., ± 0.5 inches). Compare standard industry measurements in our Polo T-Shirt Size Chart Guide.

4. Colorway & Artwork Placement Pages

Artwork sheets specify the exact placement of branding elements in millimeters from key reference points (e.g., “Left chest embroidery placed 18 cm down from High Shoulder Point and 8 cm in from center placket”). Color codes must be stated in standard Pantone TCX / TPX codes. Learn more in our Pantone Dyeing & Color Guide.

5. Label, Tagging & Packaging Details

Instructions detailing:

• Woven main brand label vs heat-transfer tagless neck print coordinates.
• Satin care/wash label positioning (typically sewn into left inside side seam 10 cm above hem).
• Custom hangtags with barcode stickers and eco-friendly polybag packing specs.

Common Tech Pack Mistakes That Delay Production

1. Specifying Retail Sizes Without Millimeter Dimensions: Telling a factory “Make it like a Zara size M” leads to disaster because brands re-cut patterns every season. Always provide hard measurements.
2. Forgetting Industrial Stitching Callouts: Specify if seams require 4-thread overlock, twin-needle coverstitch, or flatlock stitching.
3. Ignoring Fabric Shrinkage Allowances: A 100% cotton pique fabric naturally shrinks 3% to 5% lengthwise in washing. Professional tech packs state whether measurements are *pre-wash* or *finished washed garment*.
