- The Stretch Pack: How It Works
- Individual packs or packs grouped together pass the curtain of film which has been formed.
- The forcing rod, the film stretching unit and the side welding station are controlled by a servo motor and can be function fully synchronized in such a way that each can be precisely set to the correct pace.
- The stretch packs can be formed without having to pass through a shrink tunnel.
- The forcing rod pushes the pack through the curtain of film.
- During the whole operation, the film stretching unit keeps the packaging film under tension in function of the forcing movement and the side welding.
- The side sealing station consists of a system that forms flat preheated seals with a mechanical cutting device.
- The sealing time and cool-down time are controlled electrically.
