Side or bottom gusset for bulky items. Food-grade available.
Gusseted poly bags feature expandable side or bottom folds that allow the bag to open into a box-like shape, accommodating bulky, irregularly shaped, or three-dimensional products. When empty, the gussets fold flat for efficient storage, taking up no more shelf space than a standard lay flat bag. This makes them a practical choice for operations that need to stock bags without dedicating excessive warehouse space to packaging materials.
Side gusset bags are the most common configuration, folding inward on both sides to create a rectangular opening when filled. This design conforms neatly around products with depth, such as folded clothing, boxed items, baked goods, and industrial parts. Bottom gusset bags fold at the base, allowing the bag to stand upright on a shelf or display surface. Both styles are available in FDA-grade LDPE for direct food contact, meeting 21 CFR 177.1520 requirements.
One of the key advantages of gusseted bags over oversized lay flat bags is material efficiency. When you use a lay flat bag for a bulky product, you end up with excess material bunching at the sides, creating a sloppy presentation and wasting poly. A gusseted bag uses the fold to distribute material evenly around the product, resulting in a cleaner appearance and actually using less film per bag. For retail applications, this cleaner fit translates directly to a more professional look on the shelf.
Gusseted bags are widely used in the food industry, particularly for bakery products, produce, coffee, pet food, and bulk dry goods. The side gusset design works exceptionally well for loaf-shaped products like bread and for bags that need to be displayed upright on retail shelves. In the industrial sector, gusseted bags are the go-to choice for packaging motors, pumps, valves, and any irregularly shaped component that would not fit efficiently in a flat bag.
All gusseted bags from Flexible Poly Industries are manufactured from virgin LDPE resin and are available with custom flexographic printing up to 6 colors. Printed gusseted bags are common in bakery and retail applications where brand presentation matters. We can print logos, ingredient lists, nutritional panels, UPC codes, and any custom artwork directly on the bag.

Our standard gusset sizes range from 2" to 10" gussets in bag widths from 4" to 20". The gusset measurement refers to the total expansion depth, which is split evenly between both sides of the bag. Custom dimensions are available for any application where our standard sizes do not fit your product. We ship stock gusseted bags from our Los Angeles facility and manufacture custom sizes with competitive lead times.
For bakeries, food processors, and retail operations across Southern California and nationwide, Flexible Poly Industries provides the gusseted bags you need at manufacturer-direct pricing. Call (626) 250-2030 for stock availability or to request a quote on custom gusseted bags.
Bread, pastries, produce, coffee, and bulk food items packaged in FDA-grade gusseted bags. The side gusset design is especially popular for bakery loaves and any product that needs to stand upright for retail display. Micro-perforation is available for baked goods that require ventilation.
Folded garments, boxed products, gift items, and retail merchandise packaged for a clean, professional presentation. The gusset allows the bag to conform to the product shape rather than bunching excess material at the sides, which is critical for retail shelf appeal.
Pillows, blankets, towels, comforters, and soft goods that have significant depth and would not fit properly in a standard lay flat bag. The expandable gusset accommodates the product thickness while keeping the bag neat and allowing it to be heat sealed at the top.
Motors, pumps, valves, and irregularly shaped components that require a bag with depth. Heavy-gauge gusseted bags (2-3 mil) protect parts from moisture, dust, and corrosion during storage and shipping while accommodating the three-dimensional shape of the component.

A gusseted bag has expandable folds (gussets) on the sides or bottom that allow it to open into a box-like shape when filled. This accommodates bulky or three-dimensional products that would not fit well in a standard lay flat bag. When empty, the gussets fold flat, so the bags store and stack efficiently.
Side gusset bags expand outward on both sides when filled, creating a rectangular cross-section. This is the most common configuration and works for the majority of applications. Bottom gusset bags fold at the base, allowing the bag to stand upright on a shelf or display. Choose bottom gusset when you need the product to stand on its own for retail presentation.
Measure the width of your product (this is the bag width), then the depth or thickness (this determines the gusset size), and finally the height (this is the bag length). The gusset measurement is the total expansion, split evenly between both sides. For example, a 10" wide bag with a 4" gusset opens to 10" wide by 4" deep when filled.
Yes. We offer up to 6-color flexographic printing on gusseted bags. Printed gusseted bags are widely used for bakery branding, retail packaging, and food products that require ingredient lists, nutritional information, or UPC codes directly on the bag. Contact us with your artwork for a custom print quote.
Yes. Our gusseted bags are available in FDA-grade LDPE that meets 21 CFR 177.1520 requirements for direct food contact. This is essential for bakeries, produce packers, and any food operation where the product touches the bag directly. Specify FDA-grade when ordering.
We stock gusseted bags in 1.5 mil and 2 mil gauges. 1.5 mil is suitable for lightweight food products, clothing, and general retail. 2 mil is recommended for heavier items, industrial parts, and applications where extra puncture resistance is needed. Custom gauges are available on request.
Yes. We stock the most common gusseted bag sizes in our Los Angeles warehouse for nationwide shipping. Custom sizes, printed bags, and non-standard gauges are manufactured to order with lead times typically in the 2-3 week range. Call (626) 250-2030 to check stock availability.
