¿Cuáles son los tipos de bolsas para la máquina VFFS?

Vertical Form Fill Seal (VFFS) machines are widely used in packaging for products like snacks, powders, liquids, and granules. They form bags from a roll of flat film or pre-made tubing, fill them, and seal them in a continuous process. The types of bags compatible with VFFS machines depend on the machine's design, product type, and desired packaging style. The five primary VFFS bag types—Pillow Bags, Gusseted Bags, 3 Side Seal Bags，Block Bottom Bags, and Stick Packs—each offer unique advantages for specific food applications and market positioning strategies.
