Sachet packaging machine: Selection, Configuration and RFQ Guide

Contents: application and input specification

Sachet packaging machines form and fill flat flexible packs with defined seals around the contents. Sachets can contain powders, liquids, pastes or discrete items, but these require different dosing and handling concepts; the same pack name does not establish a universal filling capability.

Provide the contents, dose, behavior and finished sachet drawing with actual film. State viscosity, dust, particles or inserted-item dimensions as applicable. Define seal positions, opening features and presentation so the offered process follows the complete pack rather than only a width and length range.

The seal region is a product exclusion zone. Fine powder, a liquid droplet or the edge of an inserted article can disrupt it. Show the supplier the difficult normal condition and inspect how the process keeps that region clear before increasing seal energy or adding inspection.

Pack material: configuration tradeoffs

Compare horizontal or vertical forming, intermittent or other motion concepts and the dosing arrangement against the application. A powder auger, liquid path and item insertion system solve different problems. Ask which product-specific modules and format parts are actually included in the quotation.

Film properties influence forming and appearance as well as barrier. Printed registration, reel winding and stiffness can change handling. Supply real reels with the intended artwork and splice expectations, retaining the qualified laminate specification so later substitutions can be reviewed.

Process integration and handover points

Assign product supply, film handling, printing, registration, filling, sealing, cutting and discharge. Establish the route for missing fills or damaged packs. If sachets are grouped or cartoned, define how count and reject information remain associated with the correct finished units.

For liquid and paste sachets, define the condition at the nozzle. Temperature, aeration and ingredient separation may affect the dose or create strings. Review upstream agitation or conditioning and ask how an interrupted fill is identified and removed from accepted output.

Installation and maintainable operating arrangements

Review cleanability of the dosing and seal areas, with extraction or drip control for the product. Confirm utilities and reel handling. Include access to seal tools and change parts, plus safe removal of partly formed sachets after a stoppage or film problem.

For powders, discuss bulk-density variation and dust generation. A small free-flowing sample may not represent a normal hopper refill. Include ordinary replenishment and difficult blends during trials, sampling accepted packs over time rather than selecting only the first favorable group.

Acceptance evidence for future formats

Run the intended formulation or item with production film and inspect dose, placement, seal cleanliness, integrity and opening. Include normal replenishment, print registration changes and restart. Evaluate completed sachets after discharge handling rather than equating every machine cycle with an accepted pack.

Opening and use are part of package acceptance. A notch or tear feature should be tested on the filled production laminate, with attention to spilling or incomplete opening. Preserve approved samples with the sealing-tool revision so the intended customer experience remains a practical reference.

OEM/ODM scope and future changes

ODM may cover shaped sachets, special dosing, inserts, fitments or transfer systems after feasibility review. Agree tooling rights and sample approvals. OEM artwork and manuals are separate requests; a change to product or laminate still needs the affected filling, sealing and opening checks.

Format expansion needs a matrix of modules, tools and materials. Some future sachets may fit the dimension range while requiring a new filler or seal geometry. Ask for a feasibility response per product family before treating a broad machine portfolio as a promise for every planned SKU.
