Turntable - A rotating platform at the base of a stretch wrapper used to place product loads
on and rotate during wrapping.
Mast - Also referred to as a tower, the tall part of a stretch wrap machine holding the film
carriage and often the control panel.
Base - The bottom frame of a stretch wrap machine connecting the mast and the turntable.
Pallet Diagonal - The measurement of a pallet across diagonally opposite corners.
Pre-stretch Rate - The amount of film stretch measured in percentage.
Load Force - The amount of tension applied to a stretch film when wrapping a pallet load.
Directly related to the amount of pre-stretch rate attained.
Film Carriage - A film holder that is attached to the mast of a stretch wrap machine. The
film carriage either mechanically or manually moves up and down during pallet wrapping.
Control Panel - The primary control input for a stretch wrap machine, often containing power
on/off, pre-set settings, load force, and more.
Load Sensor - Used on a mechanically operated stretch wrap machine to identify the height
the film carriage needs to obtain to wrap the top of the pallet load.
Photo-Eye - The most common form of load sensor using a beam that bounces off the pallet
back to the photo-eye to detect pallet height.
Laser Eye - A form of load sensor using a laser to detect the height of a pallet. The laser
beam does not require refraction back to the laser eye.
Soft Start/stop - A slower start and stop of the stretch wrap turntable to reduce product
Top Wrap - The wrap at the top of the pallet load, often consisting of 2-4 wraps depending
on the load.
Bottom Wrap - The wrap at the bottom of the pallet load, often consisting of 2-4 wraps
depending on the load.
Error Code - A reading on the control panel displaying an error has occurred.
Idler Wheels - Rotating wheels on the base of the stretch wrap machine used to assist
Turntable Drive - The motor power and material used to rotate the stretch machine turntable.
Most often, the drive is belt or chain driven.
Porch - The extra area on a pallet ramp for an electric pallet jack to maneuver when
offloading a pallet.
Limit Switch - Safety switches to stop the film carriage from raising or lowering if
