When it comes to packaging, one of the most overlooked aspects is GSM (Grams per Square Meter). This technical detail, which defines the thickness and weight of the packaging material, plays a significant role in durability, product protection, and overall aesthetic appeal. GSM also affects packaging costs, customer experience, and ultimately, your brand’s reputation.
In this guide, we’ll break down what GSM is, why it matters, and how it directly impacts your packaging’s performance.
What is GSM?
GSM stands for Grams per Square Meter, a measure of the weight and thickness of paper or board material. Unlike simply focusing on thickness or height, GSM considers the weight based on the length and breadth of the material.
It’s important to note that thickness doesn’t always equal weight. For instance, corrugated fiberboard may feel thick due to its structure, but it won’t always be heavier.
However, a higher GSM typically indicates a thicker, heavier material. Higher GSM often correlates with durability and better print quality, making it a preferred choice for premium packaging.
Why is GSM Important in Packaging?
Understanding GSM is crucial because it impacts both the functionality and presentation of your packaging. Here’s why it matters:
-
Durability: A higher GSM equals more sturdiness. For example, a 300 GSM box is far more durable than a 120 GSM box. This is essential when packaging heavy or greasy foods like curries or delicate apparel.
-
Leak Prevention: Packaging with a higher GSM like the Kraft Containers with PeT Lids (image below) can better handle moisture and grease, preventing leaks and collapses, which are especially important in food delivery.
-
Brand Perception: Packaging influences how customers perceive your brand. A higher GSM feels more substantial and premium, making it perfect for upscale restaurants or luxury apparel brands.
-
Unboxing Experience: Today’s customers value the unboxing experience as much as the product itself. A well-constructed box with higher GSM creates a memorable experience, making your brand stand out.
Understanding Common GSM Paper Thickness & Its Applications

Does Higher GSM Mean Higher Cost?
While higher GSM materials might seem more expensive at first glance, they can actually be cost-effective in the long run. Finding the right balance between GSM and cost is essential. You don’t need to go for the highest GSM all the time, but you also don’t want to skimp on quality where it counts. Here are a few strategies to optimize costs:
-
Use medium GSM for lighter products: For lighter foods or clothing, a 150-200 GSM paper may provide the necessary protection while saving costs.
-
Choose premium GSM for premium products: For high-end apparel or food items, a 300 GSM box adds a luxury feel that reinforces the premium nature of your brand.
-
Consider eco-friendly alternatives: Materials like bagasse and recycled paper can offer cost-effective solutions while maintaining a high-quality feel.
Cost-Saving Tips:
- Use high GSM where necessary: Not all products need high GSM. Lighter or non-greasy foods and basic apparel can use medium GSM (150-200) for optimal cost-efficiency.
- Buy in Bulk: Ordering larger quantities of packaging can significantly reduce the cost per unit.
5 Key Tips to Choose the Right GSM for Your Product
Selecting the right GSM for your packaging depends on various factors, including your product type, delivery distance, and branding goals. Here are five key tips:
-
Know Your Product’s Weight: Heavier products like full meals or heavy garments require higher GSM (250-300). Opt for higher GSM when packaging items with multiple components or heavier fabrics.
-
Consider Moisture and Grease Levels: For greasy or moist foods, choose packaging with at least 200-250 GSM to avoid leaks. For instance, burgers, pizzas, and fried foods should be packed in sturdy boxes.
-
Delivery Distance: Longer delivery routes demand more durable packaging. If your product will be in transit for a long time, a 300+ GSM option is your best bet.
-
Branding and Customer Experience: If you want your packaging to offer a premium unboxing experience, invest in higher GSM. This is especially crucial for luxury brands, where every detail of the packaging contributes to the customer experience.
-
Test Before You Commit: Conduct tests to ensure your packaging can hold up under real-world conditions. Simulate deliveries and see how the packaging fares. This helps prevent costly errors and disappointed customers.
