Sachet sealing machinery

Sachet sealing machine considerations before buying

Compare sachet sealing requirements for powder, granule and liquid packs before choosing a form fill seal or multi-lane sachet machine.

Specification focus

Keep the machine choice tied to the product and pack.

Seal quality depends on film, product contamination, jaw temperature, pressure and dwell time as much as on machine speed.

The seal must hold product safely, look consistent and suit the film. Poor film choice or product in the seal area can cause leaks or weak packs.

Powders may dust into the seal, liquids may drip and granules may sit across the seal area. Each product needs specific control at the filling point.

Sachets can be made using vertical form fill seal machinery, multi-lane sachet systems or specialist liquid sachet machines depending on the product.

Buyer questions

Common causes include incorrect film, temperature, pressure, dwell time or product contamination in the seal.

Only with careful review, because dosing and seal-area control differ between powders and liquids.

Send product samples, sachet dimensions, film type, target dose and output target.
