Spouted Pouch Filling: Agree the Supplied Bag State

A premade pouch can arrive as a converted package for a compatible filler. In one documented equipment example, SIG's Prime 240 fills a premade center-spouted pouch through its installed spout. In another documented system, SIG describes an HFFS line that forms a pouch from rollstock, fills through the open top and seals the fitment on the line. Those examples establish that the machine and incoming package are linked; they do not establish P&M's equipment or a universal configuration.

The brand should ask its filler for the actual machine model, handling drawing and receiving specification before approving empty pouches. “Spouted pouch” alone does not answer whether the pouch arrives with a welded fitment, an unsealed filling edge, a separate cap, or another project-specific arrangement. Do not order a production lot from a marketing photograph.

Mark the intended product entry point, every edge already sealed at receipt, the edge or spout still to be closed, fitment position and orientation, cap condition, and the surface used by the machine to grip or register the pouch. The filler should confirm which steps it performs and which must be completed by the pouch supplier. Gualapack describes premade spouted pouches as manufactured before filling; that is a useful example of a supply category, not proof that every premade spouted pouch reaches every filler in the same state.

Use one revision-controlled drawing for the pouch supplier, filler and brand. Record whether the line expects separate caps, caps already placed, or caps applied after filling. Confirm the actual cap and neck interface with parts or controlled drawings. If the filler cannot accept the proposed incoming state, resolve the package design before authorizing printed production.

A drawing does not prove that product will fill cleanly or that the final package will pass the filler’s checks. Trial the actual product and intended pouch on the actual line. Record product flow and any particles or foam, pouch pickup and orientation, nozzle-to-spout or open-edge clearance, fill weight, residual headspace, seal or cap operation, leakage inspection, coding and downstream handling. The filler and brand should set acceptance criteria for the application; no universal speed, torque or leak limit follows from the pouch format.

Keep the trial sample and approved drawing tied to the same material, fitment, cap and artwork revision. If the filler changes a machine component or the brand changes the product, revisit the affected interface rather than treating an earlier trial as approval for every variant. The P&M spouted-pouch specification guide covers the wider product, barrier and fitment brief; the filling-equipment guide explains premade and form-fill-seal routes.

Ask the filler to attach its incoming-pouch specification or a marked sample. Send P&M the product and fill conditions, fill volume, intended process, packaging format, controlled bag drawing, spout and cap drawings, exact incoming state, quantity by size and artwork, trial requirements and delivery destination. Identify unknowns explicitly for joint review. P&M's flexible-packaging page is the commercial owner for custom spouted pouches; P&M supplies packaging, not the filling machine.

Request a written quote that states the supplied pouch and cap configuration and any project-specific testing or approvals. Confirm which party performs the final seal or capping step before committing to production. Submit the spouted-pouch project brief with the filler’s drawing or sample reference.
