Gusset Styles of Plastic Bags

The gusset of a bag refers to the additional material that expands the bag's capacity and creates a more spacious interior. Whether you require a bottom gusset for stability, a no gusset for a sleek presentation, or a side gusset for added capacity, choosing the right gusset style can enhance the functionality and appeal of your packaging solution.

• Bottom Gusset: Bags with a bottom gusset are manufactured to expand at the base, providing extra room for bulkier items or products that require more space. This style is ideal for packaging items like bread loaves, produce, or larger quantities of ingredients. The bottom gusset helps the bag stand upright, making it easier to load and display items for sale.
• No Gusset: Some plastic food grade bags, also known as flat bags, are constructed without a gusset, offering a sleek and simple design. Bags without a gusset are best suited for flat or light weight items that do not require additional space. These bags are commonly used for packaging items like sandwiches, cookies, or small pastries.
• Side Gusset: Bags with side gussets expand along the sides, allowing for increased storage capacity without compromising the bag's overall shape. Side gusset bags are versatile and can accommodate a wide range of products, including snacks, candies, or bulk items. The expandable sides make it easier to pack items efficiently and maintain the bag's structural integrity.
