Side gusset poly bags provide durable, flexible packaging for bulky or irregularly shaped items across foodservice, industrial, and retail applications. Made from LDPE polyethylene, these bags offer excellent clarity, moisture resistance, and dependable strength. The expandable side gussets allow the bag to open wider, increasing capacity and making them ideal for packaging products that require extra volume compared to standard flat poly bags.
Side gusset poly bags are designed to provide additional capacity compared to standard flat poly bags. The gussets along the sides of the bag expand when filled, allowing the bag to accommodate bulky, irregular, or high-volume items while maintaining a compact footprint when empty.
Common Uses for Gusset Bags
Foodservice packaging such as baked goods, produce, and bulk ingredients
Industrial parts and hardware packaging
Retail packaging for bulky merchandise
Warehouse storage and inventory protection
Packaging irregular or high-volume products
Understanding Side Gussets
Side gussets are folds along each side of the bag that expand outward when the bag is filled. This design allows the bag to open wider and hold more product than a standard layflat bag of the same width. Gusset bags are often used when packaging items that require additional volume or depth.
Choosing the Right Thickness
1–1.5 Mil: Lightweight foodservice or retail items
2 Mil: General-purpose industrial packaging
3–4 Mil: Heavy-duty packaging for sharp or bulky items
Material Options
Most gusset bags are manufactured from low-density polyethylene (LDPE), which provides excellent clarity, flexibility, and moisture resistance. This material makes gusset bags suitable for foodservice, industrial packaging, and retail use.
