Three-sided seal pouches are a type of flexible packaging characterized by being sealed on three sides, leaving one side open for filling the contents. These pouches are typically made from a single piece of film or laminate material. The three sealed sides provide stability and protection to the packaged contents, while the open side allows for easy filling and sealing. They are widely used in the food industry for packaging items like snacks, coffee, and condiments. Additionally, three-side seal pouches are employed in the pharmaceutical and cosmetic industries for packaging products like powders, creams, and small items.
