Heavy-Duty Rotary Arm Stretch Wrappers

The LP-1226RA | Landen Strapping

When a load cannot rotate on a turntable, a standard pallet wrapper creates more problems than it solves. Unstable stacks, top-heavy bundles, and irregularly shaped products shift or collapse the moment a spinning platform gets involved. The heavy-duty rotary arm stretch wrapper eliminates that problem. The arm rotates around a stationary pallet, so the load stays fixed on the floor from the first wrap to the last. That single design difference opens up product types, pallet weights, and throughput levels that a conventional turntable machine cannot handle.

Landen Strapping engineers and manufactures rotary arm stretch wrappers for production environments across food processing, lumber, corrugated box, textiles, hardwood flooring, PVC pipe, tobacco, linens, and general packaging. Whether you need a pallet stretch wrapping machine for a single station or a stretch wrap machine integrated into a full conveyor line, the rotary arm configuration delivers where a turntable cannot.

Why Specify a Rotary Arm Design

A non-rotating pallet wrapper is the correct choice when one or more of these conditions exist: the load is too heavy for a turntable motor, the load is unstable and cannot be set in motion without damage risk, or the floor layout does not permit a recessed platform. Because the pallet stays stationary throughout the entire cycle, there is no practical ceiling on load weight. An unlimited weight stretch wrapper built on a rotary arm handles pallets that would stall or damage a conventional machine without any modification to conveyor height or floor infrastructure.

Specifications

Landen's heavy load stretch wrapping machine is engineered and fabricated for continuous industrial use:

• Arm rotation speed: Variable, programmable via PLC
• Film carriage: Powered pre stretch film carriage with up to 300% pre-stretch ratio
• Film compatibility: Standard stretch film rolls, 10–30 in. wide
• Load capacity: Unlimited — no turntable motor constraints
• Load footprint: Up to 60 in. x 60 in. standard (custom configurations available)
• Load height: Up to 100 in. standard (extended mast available)
• Controls: PLC with digital touchscreen operator interface
• Wrap programs: Fully programmable top and bottom wrap counts, film tension, carriage travel speed, and overlap percentage
• Power: 208–230/460V, 3-phase (configuration-dependent)
• Frame: Heavy-gauge welded steel construction
• Safety: Full perimeter guarding with safety interlocks and automatic arm braking on fault or e-stop

The powered pre-stretch film carriage delivers consistent film tension across the full load height while reducing film consumption by up to 50% versus a non-powered carriage. Over a full production year, that reduction in stretch film usage is a measurable cost offset against the machine investment.

Programmable Control for Consistent Containment

The programmable stretch wrapper stores multiple wrap profiles, so operators switch between products or containment specifications without manually reconfiguring the machine. Each program controls arm speed, wrap counts, carriage travel rate, film tension, and total film coverage. That level of control is critical in operations where load containment requirements are set by the end customer, a carrier, or a regulatory standard.

A high-capacity stretch wrapper handles both high-mix operations and dedicated production lines running a single SKU. The same machine that wraps a heavy lumber bundle can be reprogrammed for a food processing application without hardware changes.

Applications

Landen's industrial stretch wrapper runs across a broad range of industries:

• Food processing — Frozen foods, bagged goods, and beverage cases that cannot rotate during wrapping
• Lumber — Heavy loads requiring a stationary pallet wrapping system
• Corrugated box — High-speed palletizing lines where cycle time matters
• Textiles and linens — Compressible, lightweight loads that shift on a turntable
• Hardwood flooring — Dense, top-heavy pallets requiring consistent film tension at all heights
• PVC pipe and tobacco — Fragile or long-format loads benefiting from precise carriage control
• General packaging — Any operation where load stability, weight, or plant layout rules out a turntable

Line Integration and Automation

The semi-automatic rotary arm stretch wrapper operates with a single operator initiating each cycle. For higher-volume lines, the machine is available in fully automatic configurations that integrate with conveyor systems, pallet sensors, and upstream palletizers as part of a complete pallet wrapping system. Optional features include top sheet dispensers, film clamp and cut mechanisms, and remote monitoring for production tracking and fault diagnostics.

Landen's engineering team designs each installation around the specific conveyor height, floor layout, and throughput rate of the facility. The rotary arm design requires no pit and no recessed floor structure, which simplifies integration as standalone packaging automation equipment or as part of a connected line.

Additional strapping equipment is also available for complete end-of-line packaging solutions.

Landen Strapping starts every project with an onsite evaluation. Before recommending a machine configuration, the engineering team reviews the load profile, floor layout, throughput target, and any containment specifications. Once installed, 24/7 service and support keeps the line running.

When you reach out, be prepared to cover a few key details: what product you are wrapping and its typical pallet weight and height, who currently supplies your stretch film and what specs you are running, your target throughput in pallets per hour, and whether you are integrating with an existing conveyor system. Those answers determine whether the standard rotary arm pallet wrapper configuration fits or whether a custom design is the right path.

Submit your application details through the RFQ page or contact Landen's team directly through the Contact page. An engineer will follow up to confirm the right configuration for your load containment equipment requirements.
