Gusseted bags are used as an alternative to flat bags for many products, such as mattress bags, furniture covers, food products and more. Gusseted bags include an extra piece of material in the sides, bottom, or both to allow for more room and better strength.

Bottom-Gusseted Bags

A variation on gusseted bags, bottom-gusseted bags feature additional material at the bottom of the bag that allows it to stand up on its own, or easily slip over a product. This type of bag is available in a variety of styles and sizes. Pet food and coffee bean bags are common examples of bottom-gusseted bags.

This type of bag is the simplest (think of a zip-top bag), but also offers nearly limitless options for customization. From color to printing to size and thickness, layflat bags are a blank canvas.

These bags come pre-sealed along the side(s) of your choosing, allowing for easy access on the other side for filling with your product. For example, small pouches for salad dressing may come sealed along three sides. Once the product has been added, the last side can be sealed.

Compartment bags offer multiple options for customization depending on your product. They’re used when you want to package multiple pieces separately, yet keep them together.
