For thick products such as creams and gels, piston or paste pumps combined with servo control are generally used. Using paste or piston pumps together with servo control makes the filling smooth and uniform, and also helps keep the sealing precise and clean, which is especially important for cosmetic and personal-care products.

To keep the pouch in good shape during filling, the pouch packaging machine uses an efficient gripping system together with a smooth, well-controlled filling movement, preventing the pouch from collapsing or forming wrinkles and helping the final pack come out neat and well presented once it is sealed and placed on the shelf.
