Pakcaging Styles

Stand-up Pouch (Doypack): This is the most common style for granule food products such as rice, sugar, nuts, seeds, or candies. It features a bottom gusset that allows the pouch to stand upright on retail shelves, providing excellent stability and visibility. This style is ideal for smaller to medium-sized quantities of granulated food.
Flat Bottom Pouch (Box Pouch): This style offers increased capacity and better stability, making it suitable for larger quantities of granule foods. The flat bottom structure allows the pouch to stand firmly, providing more volume for bulk packaging. It’s often used for products like dried beans, grains, or pet food.
Zipper Stand-up Pouch: A zipper can be added to the stand-up pouch to provide resealability, which is convenient for consumers who need to access products like nuts, dried fruits, or other granular foods multiple times. The zipper helps maintain product freshness and prevents spillage.
Quad Seal Pouch: This type of pouch features seals on all four corners, providing more strength and durability, making it suitable for heavier or bulkier granulated products like larger quantities of cereals or dried goods. The quad-seal design keeps the pouch shape intact during handling and storage.
