How to Choose the Right GSM for Your Packaging

What is GSM?

GSM (grams per square meter) measures the weight and thickness of paper or cardboard. It's a critical specification that directly affects your packaging's strength, appearance, and cost.

GSM Ranges and Applications

120-200 GSM - Lightweight

Best for: Inner inserts, tissue paper, lightweight product wrapping

• Cost-effective for non-structural elements
• Easy to fold and manipulate
• Not suitable for shipping boxes

250-300 GSM - Medium Weight

Best for: Folding cartons, retail boxes for light products, labels

• Good balance of cost and strength
• Suitable for products under 500g
• Provides adequate printing surface

300-350 GSM - Standard Weight

Best for: Most retail packaging, gift boxes, mailer boxes

• Most popular choice for e-commerce
• Handles products up to 2kg
• Excellent for printing and finishing

350+ GSM - Heavy Weight

Best for: Premium packaging, rigid boxes, heavy products

• Maximum durability and luxury feel
• Required for heavy items (2kg+)
• Higher cost but premium perception

How to Calculate Your GSM Needs

Follow these steps to determine the right GSM for your project:

1. Weigh your product: Heavier products need higher GSM
2. Consider shipping method: Courier vs postal requires different strength
3. Evaluate brand positioning: Premium brands benefit from higher GSM
4. Factor in budget: Higher GSM costs more per unit
5. Test with samples: Always request samples before full production

Cost Implications

GSM directly affects your packaging cost. Here's a rough estimate:

• 250 GSM box (1000 units): ₹15-20 per unit
• 300 GSM box (1000 units): ₹18-25 per unit
• 350 GSM box (1000 units): ₹22-30 per unit

Remember: The cheapest option isn't always the most cost-effective. Damaged products cost far more than slightly higher GSM packaging.

Common Mistakes to Avoid

• Under-speccing GSM: Leads to damaged products and returns
• Over-speccing GSM: Wastes money on unnecessary strength
• Ignoring material type: Kraft vs white board affects strength regardless of GSM
• Skipping samples: Always test before committing to large orders
