Choosing the Right Stretch Wrapper for Your Operation
Choosing the right stretch wrapper is one of the most important packaging decisions a company can make. The wrong machine can create bottlenecks, increase labor costs, waste stretch film, and lead to damaged products during shipment. The right machine, however, can improve throughput, reduce freight claims, increase load consistency, and provide years of reliable performance.
With so many options available—including turntable wrappers, rotary arm wrappers, overhead wrappers, orbital wrappers, semi-automatic systems, and fully automatic packaging lines—it can be difficult to determine which solution best fits your operation.
This guide will help you understand the major types of stretch wrapping equipment, the applications they are best suited for, and the key factors to consider before making an investment.
Start With Your Product
Before evaluating machines, begin by evaluating what you are wrapping. Questions to consider include: What are the dimensions of your products or pallet loads? How much do your loads weigh? Are the loads stable or unstable? Are products palletized or non-palletized? Are products long, oversized, or irregularly shaped? How many loads are wrapped each day? The answers to these questions will quickly narrow down which packaging technologies are best suited for your operation.
Turntable Stretch Wrappers
Turntable wrappers are the most common stretch wrapping systems found in manufacturing, warehousing, and distribution operations. With a turntable wrapper, the pallet load rotates while stretch film is applied from a stationary film carriage.
Best Applications
- Standard pallet loads
- Warehousing and distribution
- Manufacturing facilities
- Moderate production volumes
Advantages
- Cost-effective
- Easy to operate
- Minimal floor space requirements
- Reliable and proven technology
Considerations
Turntable wrappers work best when loads are stable enough to rotate safely. Extremely tall, heavy, or unstable products may require a different approach.
Rotary Arm Stretch Wrappers
Rotary arm systems keep the load stationary while a rotating arm applies stretch film around the product. Because the load does not rotate, rotary arm wrappers are ideal for unstable or fragile loads.
Best Applications
- Tall pallet loads
- Lightweight products
- Unstable loads
- High-speed operations
Advantages
- Better load stability during wrapping
- Faster wrapping speeds
- Reduced risk of product shifting
Considerations
Rotary arm systems typically require more floor space and a larger investment than turntable wrappers.
Overhead Stretch Wrappers
Overhead stretch wrappers are designed for heavy, tall, or difficult loads moving on conveyor systems. These systems apply film from above while the load remains stationary or moves through the wrapping zone.
Best Applications
- Concrete products
- Insulation
- Building materials
- Heavy industrial loads
- Conveyorized packaging lines
Advantages
- Handles challenging loads
- Ideal for automated packaging lines
- Excellent load containment
Considerations
These systems are generally selected for higher-volume operations where automation and throughput justify the investment.
Orbital Wrappers for Long Products
Not all products can be wrapped using traditional pallet wrappers. Long products such as roofing panels, metal trim, roll formed products, tube and pipe, extrusions, lumber, and molding often require an orbital or horizontal wrapping system. Orbital wrappers pass the product through a rotating ring that applies stretch film around the length of the bundle.
Advantages
- Protects long products
- Provides weather resistance
- Reduces handling damage
- Improves bundle integrity
Considerations
Orbital wrappers are application-specific equipment designed for products that exceed the capabilities of conventional pallet wrappers.
Semi-Automatic vs. Fully Automatic
One of the biggest decisions is whether to choose a semi-automatic or fully automatic system.
Semi-Automatic Systems
Ideal for:
- Lower-volume operations
- Single-shift facilities
- Manual forklift loading
Benefits include:
- Lower acquisition cost
- Simpler operation
- Faster installation
Fully Automatic Systems
Ideal for:
- High-volume production
- Multiple shifts
- Conveyorized operations
Benefits include:
- Reduced labor requirements
- Increased throughput
- Consistent wrapping performance
- Improved packaging efficiency
The break-even point often depends on labor costs, production volume, and long-term growth plans.
Consider Future Growth
One of the most common mistakes companies make is purchasing equipment based solely on current requirements. When evaluating packaging equipment, consider expected production growth, new product lines, additional shifts, automation goals, labor availability, and future throughput requirements. A machine that meets today’s needs but cannot support tomorrow’s growth may ultimately cost more than selecting the right solution from the start.
Key Factors to Evaluate
Throughput Requirements
How many loads must be wrapped each hour?
Product Characteristics
Size, weight, shape, and stability all influence equipment selection.
Available Floor Space
Some systems require significantly more space than others.
Labor Requirements
Automation can reduce labor dependence and improve consistency.
Film Performance
Proper film delivery systems can significantly reduce stretch film consumption and operating costs.
Service and Support
Reliable equipment backed by experienced service and parts support often delivers the lowest total cost of ownership.
Final Thoughts
There is no one-size-fits-all stretch wrapping solution. The best equipment choice depends on your products, production volume, labor availability, automation goals, and long-term growth plans. Whether you are wrapping standard pallet loads, heavy industrial products, long metal bundles, or high-volume conveyorized shipments, selecting the right packaging equipment can improve efficiency, reduce costs, and help ensure products arrive safely at their destination. Taking the time to evaluate your operation carefully today can prevent costly packaging problems tomorrow.
