Bag Knowledge
Polyester is one of the most commonly used materials for drawstring bags. It’s lightweight, durable, and cost-effective—making it ideal for promotions, giveaways, dust bags, or general storage.
Not sure which polyester grade to choose? Here’s a simple breakdown of the most popular types:
These thinner polyester fabrics are affordable and flexible. They’re perfect for short-term use or as promotional giveaway bags. Their lightweight nature also helps reduce shipping costs, especially for bulk orders.
If you’re looking for something that feels more high-end, 420D polyester has a denser weave and firmer structure. It’s great for brand events or corporate gifts where a better visual and tactile impression matters.
Some 420D polyester fabrics come with a PU coating, which makes the surface look stiffer. However, for drawstring bags that are often folded or compressed, coated fabrics can show white crease marks over time. That’s why most drawstring bags don’t use coated polyester. Such materials are more suitable for structured bags like cooler bags, which are not frequently folded and often have inner linings.
For giveaways or promotional events, 190D and 210D offer the best value and practicality. If you want a more polished look for a higher-end occasion, 420D is a solid step up.
