Liquid VFFS Sachet Machine

Liquid sachet application

Planning a liquid VFFS sachet application

The machine combines piston-pump dosing with vertical pack forming and sealing. The existing configuration includes an 80 litre hopper with mixer, colour-mark sensing and adjustable sealing, but the final setup must be proven with the actual liquid, film, dose and finished sachet dimensions.

Control contamination of the seal

Liquid on the sealing faces can prevent a consistent closure. Splashing, product stringing and movement of the forming tube should therefore be checked with the real product. Dose timing, headspace, cut-off and sealing sequence may need to be balanced against output. A visually closed sachet should be allowed to cool and then assessed for leakage and handling damage.

The specified seal style must match the film and finished-pack requirement. Confirm sachet width, cut length, fill position, headspace, print orientation and coding area before artwork or reel dimensions are fixed. Where multiple pack sizes are planned, identify which parts and settings change and how long the production team can allow for changeover.

Compare integrated VFFS with other pouch routes

This machine forms the sachet from reel material. If the project requires a shaped, gusseted or otherwise specialist pre-made pack, compare the pre-made pouch filling machine. For other reel-fed formats, review the VFFS category and the broader sachet filling range.

Provide the product, proposed film reel or material data, finished sachet drawing, dose range, target output, utilities and available floor space. Include any coding, checkweighing or downstream conveyor requirement. A timed sample trial is the appropriate way to confirm the practical rate and seal quality for the selected combination.
