Salt Sachet Packaging Machine

SUK multi-lane salt sachet packaging machines form, dose, fill, seal and cut free-flowing fine granular salt from roll film to produce small three-side seal sachets or stick packs. Crystal size, flow, dust, static, moisture pick-up and corrosion exposure are reviewed from your salt sample before the configuration is confirmed. Lane layout, dose, film and output are finalised from your salt sample and packaging requirements.

Description

The SUK salt sachet packaging machine is a multi-lane salt sachet / stick-pack configuration that works from roll film. Each lane is formed from the roll, dosed with salt, filled, sealed and cut into a finished sachet or stick pack in one continuous in-line sequence. It is intended for B2B salt packing operations that need large numbers of small single-serve salt portions produced in parallel.

This page covers free-flowing fine granular salt, including refined table salt and fine free-flowing salt grades. Salt is not a uniform material: crystal size, flow behaviour, dust, static, moisture pick-up and corrosion exposure all change the way a machine feeds, doses and seals it. The dosing method and the final configuration must therefore be confirmed from your salt sample, target weight, pack format, film and required output.

Solution scope

This page describes one equipment route: a multi-lane configuration that produces small three-side seal salt sachets or narrow salt stick packs from roll film.

  • Roll-film forming, dosing, filling, sealing and cutting in a single in-line workflow.
  • Multi-lane production of single-serve salt sachets or stick packs.
  • Intended for free-flowing fine granular salt within a confirmed crystal-size range.
  • Designed to connect to downstream collection, counting and cartoning equipment where required.

The scope is deliberately narrow. Large bags and premade zipper pouches are a different route and are filled on premade-pouch equipment. Coarse salt, salt blocks, rock salt and other large or irregular materials are assessed separately and are not covered by this standard sachet configuration.

Material scope: salt types this route is built around

The intended product family is free-flowing fine granular salt, packed as single-serve sachets or stick packs. Refined table salt and fine free-flowing salt grades within a tight crystal-size band are the typical starting point.

Other salt materials sit outside this route. Coarse salt, salt blocks, rock salt and other large, irregular or damp materials need a separate assessment before any route can be proposed. In every case suitability is confirmed from a sample rather than from a product name, because salt crystal size, flow, dust and moisture behaviour vary by source and by grade.

Roll-film workflow: forming, dosing, filling, sealing, cutting

Because every pack is built inside the machine from flat film, the stages are interdependent rather than independent options.

  1. Film forming. Roll film is unwound and formed into the pack shape for each lane. Film tracking and print registration are established here, because every later stage depends on the film being correctly positioned.
  2. Dosing. Salt is metered for each lane according to the confirmed target weight. The dosing arrangement is matched to the salt's flow behaviour and proven on the actual sample.
  3. Filling. The dose is released into the formed pack. Dust generation and static build-up in the filling zone are the two factors that most often disturb a stable cycle with fine granular salt.
  4. Sealing. Seal jaws close across the pack. Seal quality depends on the film structure and on the condition and cleanliness of the sealing zone, and is validated on the film that will be used in production.
  5. Cutting. Finished packs are separated and released to collection, counting or cartoning equipment, depending on the downstream plan.

Salt-specific selection considerations

Salt places a specific set of demands on a sachet machine, and these are the factors that drive the configuration. They are treated as engineering review and selection factors rather than fixed claims, because the right answer depends on your material and your plant.

  • Crystal size and flow. A tight crystal-size band usually flows predictably; a wide band, or a product with a high proportion of fines, tends to segregate and to dust more.
  • Dust. Salt dust is generated wherever the product falls. Dust on film and in the sealing zone is a common cause of poor seals, so dust behaviour is reviewed before the sealing arrangement is confirmed.
  • Static. Fine salt particles can hold a static charge and cling to film, guides and machine surfaces. Static behaviour is part of the material review.
  • Moisture pick-up. Salt draws moisture from the air, and damp salt cakes and bridges above the dosing point. Storage, handling and ambient conditions are reviewed together with the material.
  • Corrosion exposure. Salt is aggressive to many metals, so the materials and finishes of the product-contact and nearby surfaces are part of an engineering review. No specific material grade is promised here; it is selected for the application.
  • Seal-zone cleanliness. Keeping the sealing area free of salt dust is a design and housekeeping requirement that is reviewed together with the film choice.
  • Film tracking. Because salt dust and film behaviour interact, film tracking and print registration are checked as part of the configuration.

These items are reviewed together with your sample. No numeric machine parameters, material grades or performance levels are published on this page, because they cannot be stated honestly without your salt sample and packaging requirements.

Three-side seal sachets vs stick packs

A three-side seal sachet is formed from two film layers sealed along three edges, producing a flat, roughly rectangular pack. It is the familiar format for a standard single-serve salt portion and is comparatively tolerant of variation. A stick pack is a long, narrow tube sealed at both ends, designed for slim single-dose sticks; it uses film efficiently, but the narrow lane and long fill path place more emphasis on film tracking and on dust control around the sealing area.

Both formats come from the same family of multi-lane roll-film machines, but the choice is a configuration decision rather than a setting. Pack geometry determines film width, lane layout and dosing arrangement, so the format has to be fixed before the configuration can be confirmed. The companion guide below compares the two formats in detail.

Frequently asked questions

What is a multi-lane salt sachet packaging machine?

It is a roll-film machine that forms, doses, fills, seals and cuts several small salt packs in parallel from a single roll of film. It produces single-serve three-side seal sachets or narrow stick packs in an in-line sequence.

Which salt grades can this configuration pack?

Free-flowing fine granular salt, such as refined table salt and fine free-flowing salt grades within a confirmed crystal-size band, is the intended application. Coarse salt, salt blocks, rock salt and other large, irregular or damp materials must be assessed separately. Suitability is always confirmed from a sample.

Do you publish machine speed, lane count or dosing accuracy?

No. Those figures depend on the salt, the dose, the pack format and the film, so they are confirmed from your sample and packaging requirements rather than quoted in advance on this page.

How do you deal with salt dust, static and moisture?

Dust, static and moisture behaviour are reviewed from your salt sample and treated as engineering selection factors. The feeding and dosing arrangement, control of the filling zone and attention to the sealing area are all part of the configuration review; no specific control solution is promised before the sample is assessed.

Is corrosion resistance standard on this machine?

Salt is aggressive to many metals, so the materials and finishes of product-contact and nearby surfaces are part of an engineering review. No specific material or corrosion grade is published here, because the correct choice depends on your product, your plant and your operating conditions.

What is the difference between a salt sachet and a stick pack?

A sachet is sealed on three sides and is comparatively flat and wide. A stick pack is a narrow tube sealed at both ends for slim single-dose portions. Both are made from roll film, but each changes the lane layout, film width and dosing arrangement.

Can large salt bags or zipper pouches be made on this machine?

No. Large bags and premade zipper pouches are filled on premade-pouch equipment, which is a different route with different selection criteria. This page covers multi-lane roll-film sachets and stick packs only.

What should I send before requesting a quotation?

Send a representative salt sample, the target pack weight and tolerance, pack dimensions and format, the intended film, the daily production plan, factory space, electrical and air supply details, and your collection or cartoning requirements.

Are the packaging images on this page customer products?

No. The equipment images are real SUK machines. The stick pack and sachet image is an unbranded packaging-format illustration, not a customer case, product, trademark or formulation.
