Side Gusset Bags in Kalamazoo, MI

Side gusset bags feature expandable side panels that allow the bag to accommodate significantly larger product volumes than flat-back bags of equivalent front panel dimensions — the gussets expand outward when filled, creating a three-dimensional bag with large side panels that add substantial printable surface area. This combination of large volume capacity and maximum print surface area has made side gusset bags the standard for 1 lb, 2 lb, and 5 lb specialty coffee retail, premium pet food, rice, dried legumes, and large-format specialty food products.

Side Gusset Bag Applications

• Specialty Coffee: The original and still dominant application — side gusset bags with one-way degassing valves for 1 lb and 2 lb whole bean and ground coffee retail
• Premium Pet Food: Side gusset bags for 5 lb and 10 lb premium dry kibble retail — the format signals quality in the pet food category
• Rice and Grains: Large-format side gusset bags for 2 lb, 5 lb, and 10 lb rice, quinoa, and specialty grain retail
• Protein Powders: Side gusset bags for 1 lb and 2 lb protein supplement retail packaging
• Dried Legumes: Large-format bags for premium bean, lentil, and legume retail

Sealing and Closure Options

Side gusset bags are sealed at the top after filling using heat sealing, fold-over tin tie, or press-to-close zipper for reseal capability. For coffee applications, the tin tie closure is the artisan standard — the top is folded down and the tin tie bent to hold the closure, allowing the consumer to expel air from the bag before resealing to maintain freshness.
