Sachet machinery knowledge centre
Use these practical guides to define your product, pack and output, compare quotations on the same basis and reduce surprises during trials and commissioning.
Plan the project
The guides cover dosing, film, pouch architecture, output, price drivers, quotation scope and acceptance testing.
Buyer guide
A reliable sachet line starts with a complete application definition. Machine selection should follow the product and finished pack, not the other way around. Use this guide to turn your initial requirement into a clear engineering specification.

Buyer guide
There is no single useful list price for sachet machinery because the dosing system, pack format and compliance scope can change the engineering substantially. A credible budget separates the base machine from tooling, options, integration and operating cost.

Buyer guide
Vertical form fill and seal machinery makes each sachet from roll stock. A premade pouch machine receives an already converted pouch, opens it, fills it and closes it. Both routes can automate small flexible packs, but their economics, format possibilities and operating demands are different.

Buyer guide
A sachet machine can only make a reliable pack when the film structure, forming geometry, product and sealing process are compatible. Film should therefore be treated as an engineered component of the line, not as a generic consumable.

Buyer guide
A useful quotation is a technical response to a defined requirement. Send every supplier the same application data and ask them to state assumptions, exclusions and acceptance criteria. The checklist below can be copied into an RFQ or user requirement specification.
Read the guideDescribe the product, dose, finished sachet, film and production requirement in measurable terms.
Review machine architecture, included scope, assumptions, lifetime cost and support on a like-for-like basis.
Agree representative trials and acceptance criteria before the machinery is released for production.
Common questions
Start with the machine selection guide, then use the quotation checklist to prepare product, pack and performance data.
No. They help define the project, but representative product and packaging trials are needed to confirm dosing, sealing and output.
Yes. Send the product, dose, sachet, film and target output with any current drawings or quotations for review.
Tell us about your product and pack
Send the product, target dose, sachet drawing, film information and required accepted output. Lancing Ltd will review the application and recommend the next engineering step.
Use the guides as one specification sequence
The strongest quotation starts with the product and finished pack, then fixes the machinery route, film, commercial scope and evidence. Use the sequence below to avoid asking suppliers to price different assumptions.
Translate product behaviour, dose, sachet size, output and hygiene into a suitable dosing and forming process.
Define the laminate, web, registration, seal pattern, tear feature and pack-integrity checks before artwork and tooling are finalised.
Give each supplier the same product, format matrix, utilities, line scope, documentation and acceptance requirements.
Separate base machine, dosing, tooling, coding, feeding, inspection, guarding, delivery, installation, training and support.
Agree representative inputs, dose checks, seal and leak tests, registered film, run evidence, retained samples and accepted output.
Check whether roll-stock sachets, narrow stick packs or converted premade pouches best fit the product and commercial pack.
Define the project around your product and pack
Share the product, dose, finished sachet, film, output, utilities and line scope you have defined. Lancing Ltd can identify missing inputs and narrow the machine route before a detailed quotation is prepared.
Expanded technical library
These guides convert product, film, line and quality requirements into controlled information for quotation, trials, installation and routine operation.
Compare accepted output, lane sampling, changeovers, resilience and installed scope under common conditions.
Screen pumps, pistons, augers and weighing against product behaviour and production feed.
Prepare the dimensioned pack, lane map, reel, artwork and registration information.
Separate eye-mark control, variable coding, verification and fault response.
Define dose, seal, integrity, code, lane sampling and verified rejection.
Coordinate product feed, controls, coding, inspection, discharge and downstream machinery.
Plan access, utilities, interfaces, commissioning and site acceptance before delivery.
Map the complete task, contact parts, line clearance, format families and release evidence.
Isolate dose, seal, film, code, cut and lane faults using controlled evidence.
Question-led resources
Open the dedicated question library for direct answers on machine operation, product behaviour, accepted output, seal contamination and downstream packing. Each page links back to the relevant machinery and planning guide.
Understand the VFFS cycle and how accepted output differs from an instantaneous setting.
Use product-specific answers for foam, stringing, poor powder flow and fragile pieces.
Keep the seal area clear and define how finished sachets will be counted, inspected and packed.
Additional engineering resources
Choose the pack process from the finished feature, material, dosing and downstream task.
Plan suitability, guarding, isolation, controls, line interfaces and site acceptance.
Assess material evidence, dust release, containment, cleaning and competent risk assessment.
