Depending upon pouch width, the HFFS machine can make pouches in simplex or duplex operation. In case of duplex operation, one can have perforations between the two pouches.

In the HFFS machine, one can change the pouch size (width), in the given range of the machine specification, simply, by changing the machine settings.

With special attachments, the HFFS machine can also be used for making packed pouches with centre / corner spouts, re-closable zippers or slots / rounds for hanging the pouches..

The HFFS machine prevents contamination of the seal area as the filler enters inside the open pouch before dispensing the product..

Machine interlocks, such as “no bag no fill” and “no bag open no fill”, are provided to avoid wastage and downtime for cleaning. The operator is signaled when the interlocks are actuated and at the end of the roll..

Facility for data storage and downloading to PC, for production statistics, is provided.

The unwinder and bag forming sections may be replaced with a conveyor for feeding preformed pouches. A pick and place mechanism lifts one pouch at a time, and hands it over to the walking beam which moves it onward for opening, filling, closing and sealing.The machine is modular in construction for use in either a pick fill and seal or a form fill and seal mode

The HFFS machine can have provision for the installation of an additional filler for achieving higher production or for packing products constituted of a mixture of two or more ingredients to be dispensed separately.

Vertical and top sealing stations are followed by respective seal cooling stations for better seal quality.

Opening/closing movement of each pair of heat sealing jaws is parallel and not scissor type. This ensures even heating and pressure across the full seal length.

The provision of toggle arrangement in the movement of sealing jaws helps in adjusting and ensuring uniform seal pressure at all times.

1. This is carried out, successively, by two pairs of beams; fixed and walking.
2. In both cases, as the beams close and open, the pouch is, respectively, held and released by grippers on the beams.
3. Only the walking beams have back and forth reciprocal motion in the machine direction.
4. The pouch is moved away from the cutter,by the walking beams, to subsequent stations.
5. At each station, the pouch is held by the fixed beams to carry out the following sequential operations; pouch opening, filling, closing and sealing.
