Base machine architecture
A compact single-lane VFFS machine is fundamentally different from an eight- or twelve-lane platform. Frame size, sealing stations, drives, controls and product channels all scale the equipment cost. Premade pouch rotary systems add pick-up, opening and indexing stations that are not required on a roll-stock bagger.
Product and dosing complexity
A free-flowing granule can use a simpler weighing or volumetric system than an aerated powder, stringy sauce or corrosive liquid. Agitation, heating, extraction, special contact materials, pump selection and fast-clean tooling add engineering and fabrication.
Several products or a wide dose range can require multiple pistons, augers, forming sets or product-contact assemblies. Price them as defined changeover packages rather than assumed flexibility.
Pack format, film and tooling
Tooling cost is influenced by sachet width, seal pattern, tear features, corner shape and cutting method. Printed film may require registration control. Multiple pack widths can require dedicated forming tubes or shoulders, while special seal patterns may require additional jaw sets.
Speed, lane count and downstream handling
Higher output demands faster motion control, more lanes or parallel machines. The budget must also cover product feeding and equipment after the sachet machine. A line producing several hundred small packs per minute may need counting, collating, conveying and cartoning with substantial additional cost.
Coding, inspection and data
Date coding, checkweighing, metal detection, vision, seal inspection and reject verification are separate cost centres. Regulated production may also need user access, recipe controls, audit functions and documentation. Define the quality risk each option addresses.
Delivery, installation and commissioning
Include crating, freight, insurance, offloading, positioning, utilities, installation, commissioning, training and production support. Site works such as electrical distribution, compressed air, extraction or platforms are normally outside the machine supply unless listed.
Lifetime cost matters more than purchase price
Film yield, product giveaway, labour, changeover time, cleaning, spares, energy, rejects and downtime affect total cost of ownership. A cheaper machine can be more expensive over its life when it consumes more film or is difficult to maintain.
Build a comparable budget request
Ask suppliers to show the base machine, dosing system, tooling, options, documentation, delivery, installation, training and recommended spares separately. State what is included in performance acceptance and which products and films will be used for testing.
