Why Choose Our Side Gusset Bags
Custom Side Gusset Bags | Coffee, Pet Food & Specialty Food Packaging
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
- 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.
Side Gusset Bags and the Specialty Coffee Retail Standard
The side gusset bag with tin tie closure and one-way degassing valve has been the specialty coffee retail standard for decades — an association so strong that the bag format alone signals specialty quality in coffee retail contexts. Major specialty roasters (Blue Bottle, Intelligentsia, Stumptown) use side gusset bags that their customers recognize as quality indicators before reading a word of copy. For coffee roasters building specialty brand positioning, the side gusset format is not just practical packaging but a category signal investment.
Maximizing Print Surface on Side Gusset Bags
Side gusset bags present the largest printable surface area of any flexible packaging format at equivalent fill volume. The front and back panels provide standard large-format brand communication. The expanded side gussets — when the bag is filled — present two additional large panels visible from different viewing angles on the retail shelf. Many specialty food brands use gusset panels for secondary brand storytelling: origin information, processing details, ingredient callouts, and sustainability credentials that supplement the hero branding on the primary panels.

Side Gusset Bags in Irvine — FAQs
What is a side gusset bag?
A side gusset bag has expandable panels on both side edges of the bag — these gussets fold inward when the bag is empty and expand outward when filled, creating a three-dimensional bag with substantial volume capacity. The expanded gussets add large printable side panels that supplement the front and back print surfaces, making side gusset bags the format with the largest total printable area per unit of fill volume.
Do side gusset coffee bags need a one-way valve?
Yes. Freshly roasted coffee releases CO2 for 7–10 days post-roast. A one-way degassing valve allows CO2 to escape without admitting oxygen — essential for packaging coffee within days of roasting. Without a valve, the CO2 would balloon the sealed bag and potentially rupture the bottom gusset seal. All side gusset bags for coffee applications include valve placement.
What is the difference between a tin tie and a zipper closure?
A tin tie is a flat metal strip integrated into the bag's top edge — the top is folded down and the metal strip bent to hold the fold. It provides infinite reclosure cycles and no plastic mechanism. A zipper provides easier one-handed reclosure and more reliable seal. Tin ties are the artisan standard for specialty coffee; zippers are preferred for consumer convenience in pet food and food applications.
What film constructions are available for side gusset bags?
PET/foil/PE (maximum barrier for coffee and oxygen-sensitive food), PET/PE (standard food barrier), kraft/PE (natural artisan aesthetic), matte PET/PE (premium matte finish), and metalized PET/PE (high barrier with metallic appearance). All food applications use food-safe materials throughout.
