Sachet Filling Machine Frequently Asked Questions

It is packaging equipment that meters a product into a small flexible pack and closes the pack. VFFS systems make the sachet from roll stock; premade pouch systems fill an already converted pouch.

Common groups include liquids, pastes, powders, granules and small particulate products. Each group requires an appropriate dosing and product-handling system.

A stick pack is a narrow, elongated sachet, commonly produced on multi-lane VFFS machinery. The exact terminology and seal layout should be defined on a finished-pack drawing.

The machine unwinds film, forms it around a forming set, makes the longitudinal and transverse seals, doses the product, and cuts or perforates the completed packs.

The machine picks a converted pouch, opens it, presents it to the filler, then closes and seals it. Pouch quality and opening consistency are important to reliable operation.

Piston, magnetic, peristaltic or other pump technologies may be considered depending on viscosity, particles, foaming, stringing, temperature, accuracy and compatibility.

Auger filling is a common starting point, but screw geometry, agitation, extraction and dosing control must be established from bulk density, flowability, dust and aeration.

Weighing or volumetric systems are commonly evaluated. Particle size, density, fragility, segregation and target tolerance determine the preferred method.

Accuracy is product-, dose- and filler-dependent. It must be defined with a measurement method and demonstrated using representative product under agreed test conditions.

Product flow, dose, sachet dimensions, film, sealing dwell, lane count, coding, inspection and downstream handling all affect accepted output.

Evaluate multi-lane equipment for high total output of narrow sachets or stick packs, while accounting for parallel product distribution, cleaning and secondary packaging.

Often within a defined range, using recipes and change tooling. Every format should be listed before quotation because forming sets, jaws, cutters, fillers and film widths may change.

Provide the full laminate, total thickness, reel width and diameter, core, winding direction, print repeat, registration mark, seal layer and technical data sheet.

Causes include product contamination, wrinkles, unsuitable film, unstable heat, insufficient dwell or pressure, damaged or misaligned jaws and incorrect cooling.

Date, batch, lot, barcode and other variable data can be added with suitable printing equipment. Coding area, substrate, line speed and verification requirement must be defined.

Checkweighers, metal detectors, vision systems, code verification and reject devices can be integrated where the product, pack and quality-risk assessment justify them.

Compare scope, assumptions, performance, tooling, options, documentation, delivery, installation, training, spares, warranty, exclusions and lifetime operating cost against one written requirement.

Use the declared product, film and format; define run duration, accepted output, dose checks, seal tests, alarms, changeovers, rejects and documentation before the order is finalised.

Requirements vary, but commonly include the specified electrical supply and compressed air. Product feed, extraction, heating, cooling, drainage and environmental controls may also be needed.
