Sachet Packing Machines

Start with your product: powder, liquid or granule

Start with the dosing route below. Flat sachets use three-side or four-side seals; a narrow back-sealed pack belongs on the stick pack machines page. A similar finished pack does not make the dosing assemblies interchangeable.

Sachet series at a glance

Compare the series only after choosing the product route. The dimensions below are our series ranges; the largest three-side model sets the upper width shown.

The small, medium and large models in each series list 2–4, 3–10 and 4–16 lanes respectively. The two smaller three-side models stop at 75 and 100 mm width. All six series list 20–40 cuts/min; that is the cutting cycle rate, with product, dose and sachet length affecting the achievable run. Confirm the selected lane arrangement and accepted output in the quotation.

These are series ranges. Individual configurations can list their own, narrower figures: the LV-450X lotion and facial cream configuration, for example, lists sachets 15–60 mm wide per lane on 4 lanes. Treat a configuration figure as belonging to that configuration only.

Where sachet packing fits

A sachet filling machine makes a flat single-portion pack from roll film, doses the product, closes the seals and separates the finished packs. Our flat-sachet portfolio focuses on multi-lane configurations. Use all machine families if you are still deciding the packaging route.

For a definition, seal-style width table and the boundary with sticks and purchased pouches, read what a sachet is. To compare sachets with stick packs on seals, finished size and changeover questions, read stick pack vs sachet.

How to choose a sachet machine

Send the product and finished-pack requirement first. We use them to review dosing, sealing and lane layout together; an undecided input can stay open in the first enquiry.

• Product: liquid, paste, powder or granule, its viscosity or granule density, and whether it carries particles or foams
• Dosing system: piston or lobe pump for liquids and pastes, servo auger for powders, volumetric dosing for granules, matched to the product and target dose
• Sachet format: three-side or four-side seal, sachet length and width, tear notch and coding position
• Lanes and output: lane count follows sachet width and film width, and output follows the lane count and the cut rate, as described above, so state your target output
• Film: laminate structure and sealing layer, and how your product behaves against it
• Site: cleaning method, hazardous-area rules for alcohol-based products, and available utilities

For the full decision order with a worksheet to copy, read how to choose a sachet packing machine.

Fill and sachet ranges by configuration

Use each row for its named configuration. We match the fill range, film, lane layout and tooling to your product, then confirm accepted output under the agreed run conditions.

For LV-500SY / LV-700SY / LV-980SY sauce projects, use the series dimensions above and send the target volume, viscosity at fill temperature and particle size. We specify the fill range and pump tooling for the selected sauce configuration.

How a multi-lane sachet machine works

At the functional level, roll film is formed into open packs, a measured dose enters each lane, the final seals close the packs and the cutter separates them. The order and web path depend on the seal format; the diagram shows functions rather than a machine construction drawing.

Formed packs per minute equal cuts per minute multiplied by active lanes before stops and rejects. We confirm accepted packs per minute over a timed run with your product and film.

Tea equipment doses the inner bag and then encloses it in an outer envelope. Specify both materials; the flat-sachet process diagram does not describe tea equipment.

For a running machine with leaks, fill drift or misaligned print, record the affected lane, film change and last good pack in the sachet troubleshooting log. For product storage and barrier questions, see ketchup and condiment packet shelf life.

Sachet or stick pack

A flat sachet has three edge seals and a folded edge, or four sealed edges. A stick pack has a longitudinal back seal and two end seals. Choose the finished format and drawing before selecting tooling; the LV-450X lists several seal types, which must be confirmed for the quoted configuration.

• Three-side or four-side seal requirement
• Finished sachet dimensions and product headspace
• Coding position, tear notch and perforation needs
• Print registration and the position of the eye mark
• Hanging holes, display windows or shaped sachets requiring a format and tooling review

Sachet or premade pouch

A sachet is formed from roll film on the machine and sealed as it is filled. A premade pouch, such as a stand-up, zipper or spouted pouch, arrives already formed and is opened, filled and sealed on a different type of machine.

If your pack is a premade pouch, use the premade pouch family. If it is a flat single-portion pack made from roll film, this family is the right place to start.

Dosing liquids, pastes and powders

The dosing system has to deliver the portion without drips, foam or splashes reaching the seal area. Selected liquid configurations use an independent piston pump for each lane, allowing lane-by-lane fill adjustment.

• Piston pumps for sanitizer, shampoo, lotion and ketchup, with suck-back nozzle configurations to control dripping and trailing
• Rotary piston or lobe pumps and anti-clogging nozzles for sauces with particles, such as mustard
• Anti-foaming nozzles for shampoo and other foaming liquids
• Jacketed, heated hopper and agitator configurations for ketchup, mustard and sports gels
• Independent servo augers per lane on protein and pharmaceutical powder configurations
• Vacuum extraction at the dosing nozzle and sealing jaws on the pharmaceutical powder configuration to keep dust off the seal
• Volumetric dosing for drink granules, with fill set per lane during sample review

Review filling and film together

Share the product properties and film sample so dosing, product clearance from the seal and sealing conditions can be reviewed as one configuration. Check that the product is compatible with the film's sealing layer, especially for alcohol, oils and fragrances.

The 4-lane granule configuration supports OPP/CPP, PT/PE, KOP/CPP, aluminum foil, paper/PE and other laminated films, subject to the selected sealing layer. Liquid personal care configurations use multi-layer high-barrier laminates. Select SUS304 or SUS316 product-contact parts for the formulation and cleaning requirements; SUS316 contact parts are optional on the LV-450X.

Hand sanitizer and other alcohol-based products require a hazardous-area review. Send the safety data sheet and your site’s area classification so our engineering team can assess the electrical design and specify the required protective measures. Agree those measures for the selected build before ordering.

• Film laminate, foil or paper-based structure
• Product temperature and viscosity at the filling point
• Cleaning method and frequency for product-contact parts

Specifications to confirm, and why

Target output, fill tolerance, film, cleaning, utilities and footprint belong to the selected configuration. The quotation should identify which parts and services cover those requirements.

• State accepted packs per minute or per shift, rather than only a cutting-cycle rate.
• List every sachet size and ask which forming or sealing parts each change needs.
• Provide the film specification and agree sealing checks for new structures, including paper/PE, recyclable mono-material or compostable laminates.
• Include voltage, compressed-air availability and floor-space limits.

Counting, cartoning and related routes

Define the hand-off from loose sachets to counted groups, cartons or outer bags. Compare cartoning machines for the downstream project scope, or cup filling and sealing if the product belongs in a rigid portion cup.

Discuss the configuration and quotation scope

Send the product route and pack requirement through WhatsApp or use the project brief checklist. We use the brief to suggest a configuration, identify the engineering inputs needed and agree the next step.

For uncertain product flow, foaming or a new film, agree sample-test planning before shipping. Set the samples, measurements and record you need in advance. Confirm installation, training, documents and spare-parts scope in the quotation; the About page explains the LINEVO equipment business.

Compare offers against the same product, dose, sachet and film. Use the sachet machine cost worksheet to check change parts, material loss, cleaning and downstream equipment alongside the machine price.

Questions buyers ask about sachet machines

What fill volume can a sachet filling machine handle?

The named configuration table above lists 1–30 ml for LV-450X lotion and 1–50 ml for the sanitizer configuration; granule examples list 1–30 g or 1–50 g. These are separate product and dosing conditions. Request a sauce fill range against the selected series and your product.

Can one sachet machine run liquids and powders?

Not by changing settings: pumps and augers are different assemblies. We configure each frame and product-contact assembly around the chosen dosing system.

Why do liquid sachets leak at the seal?

The usual causes are product or foam on the seal area, drips or trailing from the nozzle with thick creams, a film that does not suit the product, or seal settings outside the film's window. A trial with your own product and film is the way to check.

Should I choose a single-lane or a multi-lane machine?

For flat sachets, this portfolio focuses on multi-lane machines; tea inner-and-outer bags use a separate process. Choose lanes from finished sachet width, film layout and required good output. We confirm the achievable run with the selected dosing unit, product and film.

Can one machine make different sachet sizes?

Sachet width follows the film width and lane layout. List every finished size so we can specify the forming and sealing parts, adjustments and changeover steps for the selected machine.

Can the machine run recyclable or paper-based film?

Paper/PE is listed among the films for the granule configuration, with OPP/CPP, PT/PE, KOP/CPP, aluminum foil and other laminates. For recyclable single-material, compostable or other paper-based films, send the structure, sealing-layer specification and a sample for sealing evaluation before choosing the configuration.

How many lanes do I need?

Start with finished sachet width, target accepted output and the film layout. The small, medium and large brochure models list 2–4, 3–10 and 4–16 lanes respectively. More lanes require an appropriate dosing and sealing arrangement; confirm the selected layout and timed output together.

Can parts be cleaned in place?

The mustard sachet configuration for particle-rich sauces offers cleaning-in-place provisions and quick-release sanitary fittings. Define your cleaning procedure so we can specify the parts cleaned in place, the parts removed and the access needed on your selected configuration.

Engineering basis and sources

Updated 21 October 2026. Our series dimensions, lane ranges and cutting-cycle rates guide initial format selection, while the LV-450X lotion configuration and four-lane granule configuration define their specific fill and pack-size windows. We confirm the dosing unit, lane layout, film, output and acceptance requirements in the project specification.

ASTM F88/F88M-23 defines how to measure seal-strip separation force and record specimen failure mode using a consistent holding technique across a test series. We agree the seal-strength acceptance criteria for your product and film during sample testing.
