Sachet Packing Machine

The Nexus Australia sachet packing machine forms, fills and seals single-dose sachets from a roll of packaging film. Also known as a sachet filling machine or sachet packaging machine, it handles liquids, powders, granules and free-flowing products at up to 40 packs per minute for the food, pharmaceutical, cosmetic, chemical and agricultural industries.

Whether you call it a packing, filling or packaging machine, the task is the same: turn a roll of film and a bulk product into neat, sealed single-serve sachets ready for retail or distribution. The right configuration depends on your product type, dose size, sachet style and target output, and Nexus Australia matches the machine to all four. For low-dose formats, a small sachet filling machine configuration produces compact single-serve sachets, while multi-lane versions lift output for higher-volume production.

How a sachet packing machine works

A roll of film is drawn through the machine and formed into the sachet shape. The dosing system meters a set amount of product into each pack, then heated sealing jaws bond the film and a cutter separates the finished sachets. The seal layout sets the final pack style: pillow pack, three-side seal or four-side seal. For higher output, a multi-lane sachet packing machine forms and fills several sachets side by side in a single cycle.

Filling and sealing in one machine

A sachet filling and sealing machine performs both operations in a single pass, which is what separates it from equipment that only doses product. Forming, dosing, sealing and cutting all happen in one cycle, so the product goes in as bulk and comes out as a finished, sealed pack with no separate sealing step and no manual handling in between.

An automatic sachet packing machine runs this cycle continuously from the film roll, which is how sachet packaging machinery reaches production volumes. Nexus Australia supplies sachet filling machines and sachet packaging machines across the range, from single-lane units for smaller producers up to multi-lane systems, all specified against your product and target output.

Dosing systems by product type

The dosing head is the part of a sachet filling machine matched to your product, and it is what separates an accurate, repeatable fill from a messy one.

• Powders: an auger filler meters drink mixes, protein and pharmaceutical powders by turning a screw a set number of rotations, which is what a powder sachet packing machine relies on.
• Liquids: a piston or pump filler doses sauces, syrups and liquid detergents by volume, giving a clean, drip-free fill on a liquid sachet filling machine.
• Granules and free-flowing solids: a volumetric cup or multi-head weigher doses coffee granules, sugar and seeds consistently.

Products it can fill

• Liquids: sauces, syrups and liquid detergents.
• Powders: drink mixes and pharmaceutical powders.
• Granules: coffee granules, sugar and similar free-flowing solids.
• Free-flowing products: small or irregular items that feed into the pack.

Sachet styles

• Pillow pack: a cost-effective style with space for branding.
• Three-side seal: a flat, compact sachet suited to smaller products, and the style usually meant by a flat sachet machine.
• Four-side seal: sealed on all four edges for added product protection.

Industries served

• Food: condiments and sauces, for example ketchup sachets and instant coffee packets.
• Pharmaceutical: single-use dosing such as medication doses and vitamin supplements. Pharmaceutical powder sachet packaging machines pair an auger dosing head with accurate, repeatable fills for regulated products.
• Cosmetic: lotions, creams and shampoos, such as travel-sized shampoo sachets. Cosmetic cream sachet packaging machines use piston dosing to handle thicker creams and gels without drag or drip.
• Chemical: detergent powder sachets and cleaning-agent samples.
• Agricultural: seeds, soluble fertilisers and other granular products.

Output and configuration

A single-lane machine runs up to 40 sachets per minute, depending on the product, sachet size and fill volume. Where higher throughput is needed, a multi-lane configuration runs several sachets in parallel to lift output. Nexus Australia specifies the lane count, dosing system and film handling to match your production target.

Choosing the right sachet machine

Start with your product type (powder, liquid or granule) so the correct dosing system can be fitted, then set your dose size and target sachets per minute, then choose the sachet style your market expects. If you are unsure, share a product sample and your output goal and the team will recommend a configuration. Contact Nexus Australia for a tailored quote on a sachet packing or filling machine.
