📋 How to Read a Bag Tech Pack: The BAKKA Beginner's Guide
By BAKKA Bags | India's Bag Authority

🎯 Why Tech Packs Matter (A Lot More Than You Think)

Think of a tech pack like ordering gulab jamuns from a sweet shop. If you just say "I want sweets," you get something random. But if you say "I want gulab jamuns—25 pieces, light syrup, delivered in a box by 5 PM," you get exactly what you want.

Without a clear tech pack:

• ❌ Manufacturer guesses what you want

• ❌ Supplier swaps materials without asking

• ❌ Zippers don't match your vision

• ❌ Colors are off by 2–3 shades (monsoon water impact? Nobody knows)

• ❌ Handles don't fit broad Indian shoulders

• ❌ You rework entire batches at your cost

With a clear tech pack:

• ✅ Manufacturer knows exactly what you want

• ✅ Zero ambiguity on materials, dimensions, construction

• ✅ Faster sampling (fewer correction rounds)

• ✅ 20–30% lower production costs (no surprises)

• ✅ Consistent quality across all units

In India's manufacturing ecosystem—from artisan workshops in Jaipur to ISO-certified facilities in Tamil Nadu—a tech pack is the only document that ensures consistency.

📑 The 7 Critical Sections You Must Understand

1. Cover Page: Your Bag's ID Card 🎫

This seems obvious but causes 40% of manufacturing disasters.

• Style Number: e.g., "BAKKA-VOYAGER-25L" (your unique identifier)

• Version Number: Rev A, Rev B, Rev C, OR date-marked (e.g., 15-Jan-2026) THIS IS CRITICAL

• Contact WhatsApp Number: Fastest communication in India's factories

Why it matters: One old version sent by accident = 5,000 bags manufactured wrong. Lost ₹3,50,000.

✓ Always label versions clearly with dates
✓ Include WhatsApp contact (email delays by 2–3 days in India)

2. Technical Drawings: 2D CAD Sketches ✏️

Manufacturers cannot build from 3D renders. They need exact 2D blueprints showing:

• Front, back, left/right, top, and interior views

• Every dimension labeled (no "approximately 20 cm"—write "20 cm ±0.5 cm")

• Zipper placements, pocket positions, strap attachment points

Common mistake: Hand-drawn sketches with vague dimensions = factory manufactures three different versions.

3. Bill of Materials (BOM): Your Ingredient List 📋

This is the most critical section. One small change = ₹100 cost difference per bag AND durability difference.

Never write:

• ❌ "Fabric" → Write ✅ "600D Polyester, PU-coated"

• ❌ "Metal zipper" → Write ✅ "YKK #5 coil, antique brass"

• ❌ "D-Ring equivalent" → Write ✅ "Zinc Alloy, D-Ring, 25mm, matte black"

4. Measurements with Tolerances: The Precision Blueprint 📏

This defines how much variation is acceptable.

Golden rule: ±0.5 cm for critical areas (laptop sleeve), ±1.0 cm for general areas.

A 1 cm difference in handle drop completely changes how the bag feels on your shoulders. In India's monsoon, a 1 cm shallow gusset = water leaks in.

5. Construction & Stitching Details 🧵

This tells factories how to assemble bags.

Stitch Type:

• Lockstitch (8–10 SPI): Premium, durable, interlocked threads

• Chainstitch (6–7 SPI): Budget, weak, unravels if thread snaps

Bartacks (Reinforcements): Zigzag stitching at stress points (handles, zipper corners, strap bases).
BAKKA Standard: Minimum 12 bartack passes. Difference? Handles stay on for 5 years vs. rip off in 6 months.

6. Hardware Specifications: Every Metal Detail ⚙️

• Zipper brand/type (YKK, not "equivalent")

• Metal material & finish (Zinc Alloy, Antique Brass—NOT brass that rusts in monsoon)

• Protective feet at bag bottom (prevent scratches on concrete, extends life 2+ years)

• Magnetic snaps (Neodymium, gunmetal finish)

Example mistake: Specifying "D-Ring buckle" instead of "Zinc Alloy D-Ring, matte black, 25mm."
Result? Factory sends brass (rusts in monsoon rain).

7. Packaging & Branding: Your Bag's Final Presentation 🎨📦

• Logo placement: Exact measurements (e.g., "2 cm from top edge, centered, 8 cm × 5 cm")

• Pantone codes: Pantone 19-1546 (Classic Navy), NOT just "navy"

• Polybag size: Fits snugly (prevents transit damage)

• Carton weight: Realistic for logistics (heavy cartons crack during delivery)

• "Made in India" label: Mandatory for exports

✅ Your Tech Pack Checklist: Before Sending to Factory

• ✓ Version number & date clearly marked

• ✓ All sketches dimensioned (no vague measurements)

• ✓ BOM complete with exact material specs & Pantone codes

• ✓ Hardware has brand, material, finish, and code

• ✓ Measurements have realistic tolerances (±0.5 to ±1.0 cm)

• ✓ Stitching specs include SPI (8+ for premium) and bartacks

• ✓ Quality standards (AQL) defined: "0.5% major, 2.5% minor defects"

• ✓ Lead times noted: PPS 10–14 days, production 4–8 weeks

• ✓ MOQ specified: Minimum 500 units
