VFFS pouch-format guide

Pouch types for VFFS machines: confirm the format before you compare machines.

VFFS describes a vertical form-fill-seal process, but it does not mean every machine can make every pouch style. Finished dimensions, film, sealing arrangement, forming parts and optional attachments must match the required pack.

General industry terminology

Common pouch-format names you may hear when discussing VFFS.

These are general packaging-industry examples, not claims that every S.K. Packaging machine supports every format. Actual pouch compatibility must be confirmed for the selected configuration.

Pillow / centre-seal pouch

A common VFFS format made from roll film, typically with a longitudinal back seal and top/bottom seals.

General industry format. Confirm the exact seal arrangement, finished pouch dimensions and film specification with the selected machine supplier.

Gusseted pouch

A pouch with side or bottom gusseting used where additional pack volume or a different shelf shape is required.

Not every VFFS machine supports gusset forming. Confirm the required attachment and the actual pouch dimensions before ordering.

Block-bottom / quad-seal style

Structured bag styles can be produced on suitably configured vertical systems for applications that need a more defined pack shape.

This requires a suitable machine configuration and should never be assumed from the term VFFS alone.

What is confirmed in the current catalogue

S.K. Packaging's VFFS-related product direction.

The current catalogue identifies the Collar Type Pouch Packing Machine as Collar Type / VFFS and lists automatic operation with a catalogue capacity of 60 pouches per minute. Specific pouch-style compatibility is not published, so it should be confirmed from the required pouch and final configuration.

Before requesting a VFFS quote

Send the pouch as a specification, not just a name.

Terms such as pillow, gusseted or block-bottom can still hide important differences in dimensions, laminate and sealing needs.

Direct answers

Common VFFS pouch questions.

1

Does every VFFS machine make every pouch style?

No. VFFS describes the vertical form-fill-seal process, not a guarantee of every pouch format. Pouch compatibility depends on the forming set, sealing arrangement, film, dimensions and optional attachments on the selected machine.

2

Which pouch styles does S.K. Packaging's current catalogue guarantee?

The current catalogue identifies a Collar Type Pouch Packing Machine in the Collar Type / VFFS category, but it does not publish a guaranteed list of specific pouch styles such as pillow, gusseted or block-bottom. Confirm the required pouch sample, dimensions and film before final configuration.

3

Does the filler decide the pouch type?

The filler and pouch-forming system solve different parts of the job. Auger or servo-auger systems are used for selected powder applications, while cup fillers are used for suitable free-flowing products. Pouch format still needs separate confirmation.

4

What should I send before asking whether a VFFS machine can make my pouch?

Send the finished pouch sample or drawing, width and length, laminate or film structure, target fill weight, product details, required output and any special sealing or coding requirement.
