Pallet Wrapping, Stretch Wrapping and Shrink Wrapping Products

Pallet Stretch Wrappers
A new generation of pallet wrapping machines, both semi-automatic and fully automatic, designed to reduce packaging, waste and maintenance costs.

Semi-automatic turntable stretch wrapping machines (sometimes mistakenly referred to as "Shrink Wrappers) represent the entry level for many applications. The load is placed on the turntable by pallet truck or forklift truck and the stretch film is attached to it. The operator then starts the machine's wrapping process. At the end of the cycle the operator simply cuts the film and removes the load. Various turntable and mast sizes are available, enabling the customer to choose the most economical solution to suit the range of likely loads.
Core brake, electromagnetic brake and power pre-stretch film carriages are available, again enabling the customer to choose the most economical solution for his application. For high useage machines it is not uncommon for the film savings associated with power pre-stretch to enable a machine “pay-back” time to be measured in months.
An option is available incorporating an automatic film cut and grip mechanism which, coupled with a wireless remote control, enables the wrapping process to be carried out without the operator needing to leave the forklift truck.
Other options, including loading ramps and pneumatic top clamps, are also available.

Fully automatic machines are normally integrated into an automated production line and, to facilitate that integration, our control panels are designed to enable easy interfacing with external conveyor control panels. All Inpac fully automatic stretch wrapping machines feature Siemens S7 PLCs as standard although other manufacturers’ units can be fitted to suit customers’ requirements. Touchscreen user interfaces are provided for setting wrapping parameters, monitoring progress and diagnosing alarms. Power pre-stretch film carriages are fitted to ensure economical film use.
Automatic top sheet dispensers and top clamp load stabilizers are available as options to increase the machine specification flexibility.
Inpac fully automatic stretch wrapping machines are available in three ranges; turntable, rotating arm and rotating ring, all of which are normally supplied with purpose built safety fences and light curtain style personnel barriers.
The turntable range is suitable for up to 50 pallets per hour. The palletised load is delivered by the infeed conveyor to the conveyor topped turntable where it is centralised before being rotated for the wrapping process. At the conclusion of that process the load is fed to the discharge conveyor for transport to the pallet storage or handling areas.
The rotating arm range is suitable for up to 80 pallets per hour. Unlike on the turntable range, the pallet does not rotate during the wrapping process but remains static on the conveyor. A counter-balanced arm moves the film carriage and vertical mast around the load, the carriage moving up and down the mast to suit the selected wrapping pattern.
The rotating ring range is suitable for up to 130 pallets per hour. Like on the rotating arm range the pallet remains stationary on the conveyor during the wrapping process. The film carriage is fitted to a ring which is lowered around the pallet, allowing very high wrapping speeds.

Horizontal stretch wrappers

Horizontal stretch wrapping machines, which are sometimes referred to as Spiral Wrappers or Orbital Wrappers, are ideal for applications requiring long items or bundles to be wrapped for protection or collation. They are also suitable for wrapping items such as doors, worktops or laminated panels.

Semi-automatic machines represent the entry level in the Inpac range of horizontal stretch wrappers. The operator lays the product on the infeed conveyor rollers, actuates the foot switch and pushes the load through the machine. Actuating the foot switch starts the wrapping head; releasing it causes the head to return to its home position where the film is automatically cut and prepared for the next load.

Fully automatic machines just require the load to be placed on the infeed conveyor, either manually by an operator or as part of an integrated production line. The product is automatically transported through the machine head where the stretch film is applied. During normal use no operator intervention is required other than to make any desired changes to the wrapping parameters via the touch-screen interface or to change the film roll. Powered roller conveyors are available as an alternative to the standard belt conveyors. Where additional collation stability and strength is required, automatic strapping machines can be incorporated into the system.

Shrink Sleeve Wrapping Machines
Manufactured to a high level of specification, these machines offer economic film usage. Accurate clutch and brake control film feed and clamping by heat resisting rubber rollers during the sealing and cutting operation, results in strong seals. The machines feature the unique Inpac 'warm cut' knife blade system which provides reliable, low temperature film cutting. Model features include:

• 90º or 180º product feed
• Accurate clutch/brake system
• Minimum maintenance
• Choice of tunnel size & capacity
• Comprehensive electronic control system, incorporating a PLC
• Dot matrix rapid diagnostic fault finding
• Digital display of jaw temperature

Conveyor Systems
These systems are designed to move product around the facility and between separate manufacturing stages.
