Blow/Fill/Seal Machine

Automatic Liquid Packaging, Inc. Blow/Fill/Seal machine automatically delivers a package in four stages:

Stage 1

Polyethylene resin is subjected to high temperature and pressure, and is extruded continuously into a tubular shape, called a parison. When the tube reaches the proper length, the mold is closed and the parison is cut. The bottom of the parison is pinched closed and the top is held in place. The mold is then conveyed to a position under the blowing and filling nozzle of the sterilized machine.

Stage 2

The blow-fill nozzle is then lowered into the parison until it forms a seal with the neck of the mold. The container is formed by blowing filtered compressed air into the parison, expanding it out against the walls of the mold cavity. The compressed air is then vented from the container and product is metered into the container through the fill nozzle. After the container is filled, the nozzle is retracted to its original position.

Stage 3

At this point in the cycle, the length of the parison is at the neck of the hold is semi-molten. Separate sealing molds close to form the top and hermetically seal and form the container.

Stage 4

After the container is sealed, the molds open. The formed, filled, and sealed container is then conveyed out of the machine, and the mold returns to its point of origin to start the next cycle.
