Liquid and paste VFFS
Use this guide to compare liquid sachet packing, pump filling and paste form fill seal machinery before sending product samples, pack drawings and output targets to Lancing for a practical machine shortlist.

Lancing helps UK manufacturers compare packaging machinery by product behaviour, dosing technology, film and seal requirements, target bags per minute, available utilities and line layout. The aim is to specify the correct form fill and seal machinery route before a formal proposal is prepared.
Liquid sachet packing machinery is built around viscosity, temperature, fill volume, drip control and product compatibility. Thin liquids, sauces, gels, oils, creams and chemical liquids can require different pumps, tank feeds, nozzles and seals.
Liquid products make seal integrity especially important because any product on the seal face can create leaks. Film choice, seal temperature, dwell time, nozzle cut-off and bag presentation should be confirmed before the line is specified.
Single-machine liquid and paste form fill seal systems suit many bag sizes, while multi-channel liquid sachet machines can suit high-output portion packs. The right route depends on output, pack dimensions, fill volume and cleaning requirements.
