Gusseted Poly Bags

A gusseted poly bag includes folded material along the sides or bottom that expands when the bag is filled. This added depth allows the bag to accommodate bulky, dimensional, or irregular products while maintaining a more practical fit around the contents.

Flat poly bags are designed primarily around width and length. Gusseted plastic bags add expandable depth, making them better suited to products that are thick, boxed, rounded, or otherwise difficult to fit into a flat bag.

Gusseted bags are commonly listed by width, gusset, and length. For example, an 8W x 4G x 18L bag measures 8 inches wide, includes a 4-inch gusset, and is 18 inches long. Measure the product at its widest, deepest, and longest points, then allow additional room for loading and closing the bag.

The appropriate thickness depends on the product weight, edges, handling conditions, and required level of protection. Lighter bags can support routine packaging, while heavier gauges may be better for larger products, demanding handling, or applications with greater puncture and tear concerns.

The best format depends on how the bags will be filled, dispensed, stored, and used:

• Standard gusseted poly bags support general packaging, storage, and product protection.
• Gusseted poly bags on rolls provide convenient dispensing for repetitive packaging operations.
• UVI/UVA gusseted poly bags are intended for applications requiring added protection from ultraviolet exposure.
• Wicketed bottom gusset bags support organized dispensing and efficient loading workflows.

Depending on the individual product and application, gusseted poly bags may be heat sealed, tied, taped, stapled, or secured using another closure method. Review the product specifications and select a closure that matches the bag material, contents, and required level of security.

Some gusseted poly bags are manufactured for food-contact applications, but this should not be assumed for every product. Confirm that the specific bag is identified as suitable for food contact before using it to package food or ingredients.

Many gusseted bags are available in business-ready package and case quantities. Review each listing for dimensions, thickness, quantity, price breaks, and availability. Businesses with recurring or high-volume requirements can contact our team for ordering assistance.

Custom options may be available when standard bag dimensions, thicknesses, materials, quantities, or other specifications do not fit your application. Submit your requirements through our custom order request page for review by our packaging team.
