Seal quality after filling

Protect the pouch seal area from product, wrinkles and an uncontrolled cooling cycle.

A pouch can be filled to the correct weight and still fail commercially if product enters the seal area, the pouch is not presented flat, the seal parameters do not suit the laminate, or the pack is handled before the seal has stabilised. The weighing, pouch presentation, filling and sealing stages should therefore be assessed as one process.

What pouch samples should be tested?

Use production-intent pouches from the expected supplier and batch range, including the smallest and largest formats. Provide the complete laminate, zip, gusset, spout or special feature information and the required seal-quality method.

How can a weighed dose affect the seal?

Product can scatter, rebound or remain suspended while the pouch moves to sealing. Piece size, dust, oil, static, drop height and timing determine whether the seal area stays clean. Review the complete product path.

How should seal quality be checked?

Agree the visual and physical inspection method before the trial. The correct method depends on the pouch, product and commercial requirement. Retain failed examples and the machine state associated with them.

What should be checked after a pouch changeover?

Confirm pouch pickup, opening, fill position, headspace, product settling, seal alignment, coding, inspection and outfeed. Run enough packs to include normal stops and restarts rather than accepting only the first successful cycle.

Pouch and product review

Send filled and empty pouch samples with the product.

Include pouch drawings, laminate information, target fill, headspace, seal requirements and the intended upstream dosing method.

Final pack closure

Reliable pouch sealing starts before the pouch reaches the sealer.

The fill level, pouch presentation and cleanliness of the seal area determine whether the final closure can be made consistently.

Seal compatibility

Confirm pouch material, seal layer, total thickness, seal width and whether the pack includes a zipper, gusset or other feature near the sealing area. Temperature, pressure, dwell and cooling must be proven on the actual pouch rather than assumed from a generic material description.

Product and headspace

Powder, crumbs, oil or oversized pieces in the seal can cause weak or leaking packs. The weighing and filling stage should control the product drop and allow suitable headspace and settling before sealing.

Inspection and downstream handling

Plan coding, seal inspection, cooling, checkweighing, reject handling and collection. Finished packs should be supported so a warm seal is not distorted immediately after closing.

Evidence to provide

Send empty pouch samples, filled pack examples, material specification, target output, desired seal position and details of any nitrogen flush, vacuum, coding or inspection step.
