LFT Tray Model

Single and double tray, flat pad and film only

LFT Model with Tray


The shrink wrap machine LFT tray model is available in single and double trays, in flat pad and in film-only.

It can pack all products, even those with particularly sharp edges, thanks to the addition of a tray or a flap that protects and acts as a base for the film.

The products do not run the risk of damage to the outer packaging and are equally protected from atmospheric agents, making them easy to store and transport and being visually pleasing when displayed on store shelves.

Energy saving tunnel

The shrink tunnel present in all Zambelli Shrink wrap machines has 7 fundamental characteristics:

  1. Tunnel flow setting through adjustable holes
  2. Extra resistors already installed (zero downtime replacement)
  3. Minimum energy consumption
  4. Three possible configurations on the same tunnel (1, 2 or 3 lanes)
  5. Separate cooling section at the exit for best shrink
  6. Tunnel adjustment according to the film characteristics
  7. Possibility of working with different types of films by adjusting the air flows and temperature

Machine Details

Special groups

90° cluster rotation
90° continuous translator for multi-flavor cans

It is possible to compose the packs in: 4 flavors, 2 cans and 3 tracks; or 4 flavors, 3 cans and 2 tracks; or in 4 flavors, 6 cans and 1 track.

Cluster stacker

A conveyor with intermittent vertical movement deposits a layer on the upper surface. The upper surface is adjustable by means of a handwheel with numerical indicator based on the height of the cluster.

Subsequently a motorized trolley accompanies the product step by step with the tray formation group or on a belt to create a bundle in film only or flat pad.

Multi-flavor power supply Special feeds for channeling several rows of product with different flavors, to then be conveyed into a single feed and forming a single bundle.
It can be built in line or with rotary tables.
Removable side cards for trays

Device for inserting rectangular or "C" cards from the top into one side of the tray.

Single and double pre-retraction handle

The pre-retraction handle applicator, available in single and double, includes:

  • double scotch reel holder (1,500 m) with automatic change or single reel holder (5000 m) paper reel holder (1,500 m)
  • paper-scotch coupling and handle cut
  • paper length adjustment
  • automation and control
  • light indicator
Tray stacker

Continuous stacking unit, suitable for stacking full trays in double layer.

The complete bundle with two stacked trays is transferred to the wrapping section with shrink film.

This device includes width adjustment and tray lifting via side grip.

Lids magazine with holes for conical bottles Device for inserting a cardboard from the top with holes, to be placed on the neck of the bottles in order to keep them in the correct position during wrapping and retraction.
Continuous stacker for stackable cans

Can stacking system consisting of infeed belts complete with overlapping unit with stars.

The cans transported to the entrance of the machine are then packaged in tray + film or wrap-around.


On the Zambelli shrink wrappers it is possible to take advantage of an automatic motorized adjustment of the product guides in the areas normally adjustable by means of a handwheel for format change. All the moving parts of the machine that are subject to format change can be equipped with brushless motors for quick format change.

The carton loading operation takes place in the external area of ​​the warehouse and subsequently, independently, the movements with brushless motors feed the cartons to the main warehouse, thus increasing the autonomy of the machine.

For easier access by the operator, the reel holder and the manual 90 ° welder are placed on the side of the machine.

In machines that have an automatic welder, in case of use of printed film, a photocell stops the unwinding near the reference notch printed in the film, in order to proceed with the welding between the exhausted reel and the new one. This system guarantees the perfect position of the printed film without film waste or bundles when restarting after the reel change.

In the tray model shrinkwrappers it is also possible to process products in film only and with flat pad + film thanks to the presence of the bypass belt, a device that can be easily lifted using suitable supports when not in use.

The energy saving bulkheads are present at the entrance and exit of the heat tunnel, designed to lower automatically to reduce energy consumption and to quickly reach the temperature "set point" when the machine is started.

In combination with this, through the PLC it is possible to manage the resistances that turn on and off according to the temperature detected inside the shrink chamber.

Also through the PLC, it is possible to automatically activate the lubrication pump for a time that can be set according to the hours of operation of the machine.

The touch screen PC includes, in addition to what is described, also: the alarm signaling complete with photos and explanation for the relative reset, the video instructions for the format change, the list of recommended spare parts, the wiring diagram, the user manual and maintenance of the machine and, finally, the performance statistics of the machine.
