Automatic Linear Fill and Seal machines
for premade stand-up pouches (doypack)

The LINAPACK LFS SERIES machine range for filling and sealing premade stand-up pouches has been designed for the user peace of mind and a hygienic high quality production.

These machines are used for a wide variety of products such as food and beverage, animal/pet food, detergents, cosmetics, chemical products, etc.

The linear modular design concept offers great flexibility in the type and the number of different products to be filled as well as pouches sizes.

The flexibility and quick size change make this machine range suitable for short runs or longer productions even in 3 shifts.

The LFS series machines principle is based on a stepping conveyor on which are attached a sequence of function modules. The pouches are naturally standing on the conveyor, maintained in position by quick-change clip-on pucks. Based on this principle, any machine configuration can easily be produced.
