GSM (grams per square metre) is the single most important spec after size when ordering non-woven bags, yet it’s often the least understood. Here’s a straightforward non woven bag GSM guide.
What GSM Actually Measures
GSM measures how much a square metre of the non-woven fabric weighs — higher GSM means thicker, denser, generally stronger fabric.
Typical GSM Ranges
- 60-80 GSM — lightweight, cost-effective, suited to light retail items and giveaways
- 80-100 GSM — the most common range for everyday retail and boutique bags
- 100+ GSM — heavier-duty, suited to grocery, gifting hampers, or bags expected to carry more weight repeatedly
GSM vs Cost Trade-off
Higher GSM costs more per piece but extends reuse life and reduces tearing complaints — often cheaper in the long run for businesses that value repeat brand impressions over the lowest upfront price.
How to Decide
Match GSM to your typical bag contents’ weight, not just budget. A manufacturer should be able to recommend GSM based on what you’re actually packing, not just quote their cheapest default.
