Sewn vs. Heat-Sealed Spunbond Bags: Which is the Right Choice?

Spunbond fabric bags are primarily manufactured using two methods: sewn and heat-sealed. Sewn bags involve cutting the fabric and stitching the seams with a sewing machine, resulting in a strong, heavy-duty bag suitable for applications requiring durability and repeated use. Heat-sealing uses heat and pressure to fuse the fabric together, creating a smooth, clean seam and offering faster production, but potentially less strength than sewn bags.

The choice depends on the intended use. For short-term, light giveaways like documents or small items, heat-sealed bags are sufficient and cheaper. However, for heavy items or repeated use, sewn bags offer greater assurance.

Another advantage of heat-sealed bags is their smooth surface, ideal for printing logos or graphics requiring high clarity. Sewn bags may have visible seams but allow for customization of size, shape, and special features. Choosing the right method based on your needs and budget will ensure your spunbond bag is strong, durable, and enhances your brand image.
