Film shrink wrappers with 90° infeed


ASW 150-I ERGON - Film shrink wrappers up to 150 introductions/minute

The ASW ERGON range is composed of different models of compact shrink wrappers with single lane 90º product infeed, suitable for making packs in film only, cardboard pad + film, cardboard tray, cardboard tray + film.

The ASW shrink wrappers are suitable to pack a wide range of cylindrical, oval or square/rectangular containers at a speed of max. 150 introductions/minute, according to the machine model and the type of product to be processed.

The models of this series stand out for their compact structure that is easily adapted to the logistic end of line conditions and for fast and easy changeover, thanks to the single-lane infeed.

1A system with a single-lane infeed facilitates the correct laning of the loose containers on the conveyor. The product feeding system features a continuous motion and the pack formation is performed, in case of the ASW 80-I, by dosing belts synchronized with brushless motors, while in the ASW 150-I by an electronic separation device.


2Then, loose products are pushed by the single lane conveyor to the multi-lane conveyor. This is carried out in the ASW 80-I thanks to a Cartesian axes system, while in the ASW 150-I by a rotary system. In P and T models, a corrugated cardboard pad or blank is picked from the blank magazine by a rotary picker composed of two groups of electrical vacuum suction cups. The pad or the blank moves along the cardboard climb and places itself underneath the group of products in transit with the long side leading. The tray former operates in continuous motion.


3In the tray former, special mechanical devices fold the blank's front and rear flaps. The side flaps are sprayed with hot melt glue and then folded, thus forming the tray. The unwinding of the film is controlled by the cutting unit in the ASW 80-I and by brushless motors in the ASW 150-I.


4The film tensioning is controlled in the ASW 80-I by a system equipped with tensioning spring and in the ASW 150-I by a piston. When the operating film reel is over, a manual sealing bar joins the films. Before the pack enters the shrink tunnel, the film is cut by a knife blade controlled by direct-drive brushless motor, wrapped around the group of containers and overlapped on the bottom of the pack.

  • Machine bearing frame made of sand-blasted and powder-painted steel
  • Sliding protection doors in anodised aluminium featuring a rounded shape which let all the motors (featuring low energy consumption) be placed externally if compared to the mechanical groups they activate. The closing system of doors is equipped with a slow-down device, which accompanies the door smoothly in its final phase of closure
  • Absence of gearboxes and prevailing employment of ICOS brushless motors equipped with digital servo-driver integrated into the motor
  • Cardboard magazine situated beneath the infeed conveyor in an easily accessible position (P and T models)
  • Compact knife group with film cutting blade driven by a direct drive brushless motorization
  • Possibility to handle a wide range of film thicknesses (from 40 to 80 micron for the ASW 80-I; from 30 to 100 micron for the ASW 150-I)
  • Automatic centering system for printed film provided with marks
  • The shrink tunnel features state-of-the-art technical solutions that enables the energy consumption reduction and the maximum environmental compatibility of the processes. Thanks to the precise analysis of thermodynamic phenomena generated by the shrink process, the tunnel distributes hot air flows in an efficient and homogeneous way on the pack, thus ensuring the excellent quality of the final pack. Shrink resistances are positioned on the side walls of the tunnel.
  • Operator panel mounted on an arm sliding on a rail

Compact and ergonomic structure

Loose products get to the machine on a single-lane conveyor belt; as a consequence a divider is not necessary to lane the products. This enables to reduce the costs, as well as the space occupied by the conveyor line. Furthermore, the frame is ergonomic and functional and this enables the operator to carry out easily all activities related to use and maintenance of the installation.

Easy and quick changeover

The single lane infeed offers the advantage of working lots of different kinds of containers, with different sizes, without having to have additional belt equipment. Therefore, format changeover is much faster and easier, as there is no need to regulate the guides on the different lanes.

Product preservation and stability

Product separation doesn't stress the loose product, since this operation is carried out through dosing belts; this allows to preserve the container shape and ensures an enhanced pack stability during the separation.

Operational flexibility

These machines can package a wide range of products in several pack collations, so as to effectively meet the end user's current and future requirements. Moreover, each machine can be equipped with additional devices, which increase its basic functions and ensure a high level of customization of the final package.

Easy and cost-saving maintenance

The rounded safety doors enable to have more space inside the machine and thus to install motors externally compared to the mechanical units they drive, which allows the operator to easily perform the activities connected to the plant maintenance.

Automatic film cut

Film cutting unit equipped with direct drive motorization, that allows to easily carry out the motor maintenance, reduce the noise level, save energy and ensure high reliability and movement precision.

Ergonomic cardboard magazine (P and T models)

The cardboard magazine (for P and T models), located in an easily accessible position for the operator, ensures an ergonomic, easy, fast and safe loading.

User-friendly operator panel

The POSYC® control panel, sliding on tracks running the whole length of the machine, is a user-friendly system that enables an easy and efficient use of the packaging machine. This is possible thanks to intuitive interface, a touch screen display and diagnosis functions and real-time technical support available on the POSYC®.
