Semi automatic turntable pallet wrappers represent the entry level for many applications. The load is placed on the pallet wrapper 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. A further option is the "horseshoe" type turntable allowing pallets to be loaded by pallet truck without needing a loading ramp.
Mechanical core brake, electromagnetic core brake and power pre-stretch film carriages are available.
Power pre-stretch film carriages are designed for easy film loading and threading, reducing film reel changing time.
Other options including simple automatic film cutting, loading ramps, pit mounting frames, pneumatic top clamps, up to 3m diameter turntables, up to 4m pallet height, flat load wrapping (e.g. doors), stainless steel construction, hazardous area certification and weighing scales are also available.



Fully automatic pallet wrappers 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. Touch screen user interfaces are provided for setting wrapping parameters, monitoring progress and diagnosing alarms. 
Automatic top sheet dispensers and top clamp load stabilizers are available as options to increase the machine specification flexibility.
Inpac fully automatic pallet stretch wrappers 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 40 pallets per hour. 
The rotating arm range is suitable for up to 70 pallets per hour.
The rotating ring range is suitable for up to 120 pallets per hour.



Horizontal stretch wrappers 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 horizontal stretch wrapper 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 horizontal stretch wrapper 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 chain and roller conveyors are available as alternatives to the standard belt conveyors. Where additional collation stability and strength is required, automatic strapping machines can be incorporated into the system.



Shrink hooders

Hoods of a suitable size for the pallet being wrapped will be produced from rolls of shrink material. Machines can carry several roll sizes which, together with auto-sensing of the pallet height and 90º hood orientation, allow a variety of pallet sizes to be handled without manual intervention. The hoods will then be opened before being lowered over the pallet. A shrink frame passes over the pallatized load, shrinking the hood on to the product with hot air.

Stretch Hooding

Hoods of varying sizes are produced in the same way as with Shrink Hooding. The hoods are then opened and stretched before being applied to the pallet. Once released by the stretching head the hoods will attempt to recover their original size, producing a stable, cost effective and weather protected load.

The two most common applications normally referred to as “Shrink Wrapping” are Sleeve Wrapping and L-Sealing.   Sleeve wrapping is most commonly used as product transit packaging and protection and in most cases would leave open areas at the sides of the pack.
Inpac machines use two rolls of film, joining and cutting them in the appropriate places by the use of a long-life heated blade.  
L-Sealing is used where a total, neater wrap is required; typically for individual product wrapping. Centre-folded film is typically used for L-Sealing applications.  
In both of these applications the wrapped package or item would then pass into a heat tunnel or chamber for film covering to be shrunk.
At Inpac we can accommodate both of these popular wrapping technologies.
