Stretch wrap machines are recommended for any business wrapping more than 15 loads per day. Stretch wrap machines help to reduce waste, increase efficiency, and promote a more secure and consistent load.
Categories and sub-categories of stretch wrappers:
Manual (or Hand) Wrappers:
• Extended Core: An extension of the film's core serves as a handle for wrapping; this type of wrapper offers little stretch control and is hard on hands.
• Mechanical Brake: A simple structure supports a film roll and a mechanical brake system provides resistance creating stretch of the film.
• Pole Wrappers: Similar to the Mechanical Brake system, but the roll and brake are at the end of an extended pole, creating an ergonomic design which eliminates the need to bend to wrap the bottoms of loads and strain to reach the tops of loads.
Semi-Automatic Wrappers:
• Turntable Wrappers: The load to be wrapped sits on a turntable which spins the load relative to the film roll, which is housed in a carriage which can move up and down a fixed "mast". Stretch is achieved by rotating the load at a faster rate than the film is fed.
• Orbital Wrappers: The film is housed in a carriage on a vertical ring, the load is fed horizontally through the eye of the rotating ring, applying film to the load. A variation of an orbital stretch wrapper is a horizontal ring system, in which the load remains still while a horizontal ring is rotated around the load and moves up and down vertically relative to the load, similar to a rotary arm stretch wrapper.
• Rotary Arm Wrappers: In this system, the load remains still while a rotating arm turns around it wrapping the load. This system is used for light loads or for speeds which would otherwise cause the load to topple due to high rotation speeds.
• Hybrid Platform Automatic Wrappers: In this system, loads are placed on the turntable via fork trucks or pallet jacks. From there the process is automatic. Attaching the film to the load at the cycle start, cutting and sealing the film to the load at cycle end are all initiated via a remote control, leaving your operators free to perform other duties and avoid the arduous task of getting off and back on their fork lift trucks.
Automatic Wrappers:
Automatic wrappers are generally a variant of a semi-automatic system. Automatic wrappers include a conveyor system to automatically load the wrapping machine and automatic systems to apply, seal, and cut the film.
