Pallet Wrapping Machine Suppliers & Manufacturers

A pallet wrapping machine (stretch wrapper) wraps a palletised load in stretch film to secure it for transport and storage — preventing product movement, protecting against dust and moisture, and maintaining the pallet pattern integrity during handling. The three main machine configurations are: turntable stretch wrapper — the pallet rotates on a rotating turntable while the film carriage travels up and down the fixed mast, wrapping the film helically around the pallet; the most common type for standard pallets on a production floor or distribution centre; requires the pallet to rotate, which is suitable for stable, well-stacked loads; not suitable for very heavy or very unstable loads that cannot safely rotate. Rotary arm stretch wrapper — the pallet stays stationary on the conveyor and a rotating arm carries the film carriage around the pallet; better for unstable, top-heavy, or very heavy loads (bulk bags, drums) that cannot safely rotate; slightly more complex and expensive than a turntable; available in semi-automatic and fully automatic inline versions. Ring-type stretch wrapper — the film carriage is mounted on a large rotating ring above the pallet; very fast wrapping cycle (high throughput for high-speed beverage and FMCG lines); the pallet travels through the ring on a conveyor; the film is applied from the ring as it passes through. Pre-stretch systems: a pre-stretch unit on the film carriage stretches the stretch film before it is applied to the pallet — typically 150–300% pre-stretch. Pre-stretch has two major benefits: it reduces film consumption (a 200% pre-stretch means less film mass is used per pallet, reducing material cost and waste); it improves load containment (the stretched and rebounding film exerts higher clamping force on the pallet load than unstretched film). Modern pallet wrappers all include an electronic powered pre-stretch system.

Pallet wrapping machines use machine stretch film (cast or blown stretch film, typically 15–35 micron gauge before pre-stretch) supplied in machine rolls (500mm or 100mm width, core sizes of 50mm or 76mm). Stretch film for pallet wrapping: cast stretch film — the most common for pallet wrapping machines; produced by casting molten polyethylene onto a chill roller; very clear, low noise on unwind, consistent gauge; blown stretch film — produced by blown film extrusion; higher puncture resistance and load retention; preferred for sharp-cornered or heavy loads; coloured or black stretch film is available for security or UV protection. Film selection depends on pallet load weight, corner sharpness, storage conditions (outdoor, freezer, or standard ambient), and stretch wrapping machine compatibility. Pallet wrapping integration: in a fully automated end-of-line, the pallet wrapping machine is integrated after the palletiser on a conveyor; the wrapped pallet is then conveyed to a labelling or stencilling station (pallet label application) and discharged to the dispatch area or pallet storage. Semi-automatic turntable wrappers are used at smaller scales where pallets are moved to the wrapper by fork-lift. Wrapping program: wrapping parameters (number of base wraps, number of top wraps, carriage travel speed, rotational speed, pre-stretch level, film tension) are programmed into the machine's controller and stored as recipes per pallet format. Key suppliers: Robopac, Lantech, Signode, Robovic, Lachenmeier, and a large number of Chinese manufacturers for standard turntable models. When sourcing, specify: pallet dimensions, pallet weight, load stability, required output (pallets per hour), pre-stretch level required, integration with conveyor system, and stretch film specification.
