Arm-Type Stretch Wrapping Machine with 250% Pre-Stretch Ratio Solves High Pallet Stability Issues

Automated solution for high pallets and unstable goods
In factory outbound operations, many pallets are tall, top-heavy, or unsuitable for turntable rotation—especially in industries like chemical, construction, food, and daily chemical products. Manual wrapping is not only inefficient but also results in inconsistent tension, causing loosening, leaning, or even toppling during transport. The arm-type stretch wrapper addresses these issues through a “stationary load, rotating arm” design, achieving stable and even stretch film coverage around the pallet. This makes it ideal for high-frequency, long-term use in factories.
Pre-stretch structure reduces consumable costs
For factories, long-term film consumption often outweighs the initial machine cost. Our arm-type machine uses a pre-stretch film carriage with a 1:2.5 (250%) ratio. Under the same packaging effect, film usage is significantly lower than manual wrapping or machines without pre-stretch. For example, daily pallet packaging can save about 30–40% of film, making long-term savings far exceed the equipment investment. This is a major reason factories increasingly adopt automated stretch wrappers.
Automatic film feeding and cutting reduce labor dependency
Manual wrapping requires dedicated personnel whose efficiency depends on skill level, while labor costs continue to rise. The arm-type machine can automatically load, clamp, and cut film, operating independently without repeated human intervention. Packaging efficiency reaches 20–40 pallets per hour, ensuring stable outbound flow and uniform wrapping. Compared to hiring a full-time wrapper, the machine pays for itself quickly while reducing management burdens.
Stable structure suitable for continuous outbound use
The machine’s heavy-duty frame, variable-speed arm movement, and chain-driven lifting column provide stable operation, suitable for high-frequency, long-duration packaging. It can automatically detect load height, adjust wrapping layers and cycles, and prevent over- or under-wrapping, ensuring consistent pallet stability during transport.
High scalability to meet diverse factory needs
Optional top-press devices prevent load lifting during wrapping. For high-volume factories, the machine can integrate with conveyor lines or chain systems for online automatic packaging, reducing forklift idle time. Whether used as a standalone unit or upgraded into an automated line, the arm-type machine offers flexibility to match factory expansion strategies.
Mature manufacturing ensures long-term reliability
With years of experience in stretch-wrapping equipment, our design emphasizes stable operation, easy maintenance, and robust safety features. A single reliable arm-type machine can genuinely help factories reduce costs, increase efficiency, and standardize outbound packaging.
