How to Know When it’s Time to Invest in a Stretch Wrapping Machine

Stretch wrap is essential in the shipping world, securing pallets and protecting your products during transport but manual wrapping is time-consuming and can be an insufficient solution to handling increasing volumes or meeting quality standards.

Investing in a stretch wrapping machine, however, can replace sweat with smart – a strategic decision that can yield significant benefits for businesses in terms of efficiency, quality, safety, and cost savings.

“Pallet stretch wrapping machines help in labor relocation and free up the workers for more productive tasks. With the automatic machine, almost no labor work is required, and the result is a better one than manual wrapping,” said a global report on the pallet stretch wrapping machine market. “Consistency is the key to success. This is what a company can easily achieve via the automatic pallet stretch wrapping machine. The machines will be equally consistent while wrapping each pallet, irrespective of the load. This can greatly vary in case of manual or hand wrapping.”

It’s not always easy to tell when manual applications have become a bottleneck in operations, so here’s how to know when it’s time to upgrade from manual wrapping to a stretch wrapping machine, a move that can revolutionize your packaging process.

Beyond the Bicep Test: Signs It's Time to Automate

Manual stretch wrapping might seem like a simple task, but for businesses with high-volume shipping needs, it can quickly become a hurdle.

Here are some telltale signs it's time to invest in a machine:

• Packing on the Pressure: Is your packaging volume increasing? A growing business means more pallets to wrap, and manual wrapping simply can't keep up with the pace.
  
  
• Labor Cost Crunch: Wrapping pallets by hand is labor-intensive. Are rising labor costs eating into your profits? A machine can significantly reduce labor requirements.
  
  
• Wrap Roulette: Does the quality of your wrapped pallets vary depending on the person doing the job? Manual wrapping can be inconsistent, leading to loose or uneven wraps that compromise load stability.
  
  
• Safety First: Manual wrapping can cause repetitive strain injuries (RSI) for your employees. Machines eliminate physical strain and ensure a safer work environment.
  
  

Choosing the Right Machine: More Than Just Muscle

Stretch wrapping machines come in various configurations, so understanding your specific needs is crucial.

Here's what to consider:

• Machine Types: Turntables rotate the pallet while the wrap dispenses, while rotary arm machines wrap the pallet while it stays stationary. There are other types such as robot stretch wrap and orbital stretch wrap machines. Choose the type that best suits your workflow and space limitations.
  
  
• Throughput Matters: Consider the number of pallets you need to wrap per hour. Machines have varying speeds, so ensure it can handle your current and projected volume.
  
  
• Size Matters Too: Pallet dimensions and weight capacities vary. Choose a machine that can accommodate your largest and heaviest loads.
  
  
• Space Constraints: Measure your available workspace and choose a machine that fits comfortably within your layout.
  
  
• The Bigger Picture: Consider if the machine can integrate with existing conveyors or palletizers to create a seamless packaging line.
  
  

The Numbers Game: Cost-Benefit Analysis

Investing in a stretch wrapping machine involves an initial cost, but the long-term benefits can be substantial.

• Upfront Investment: This includes the machine cost, installation, and operator training.
  
  
• Savings Potential: Consider potential cost savings in labor, reduced film waste due to consistent wrapping, and minimized damage during transport.
  
  
• Efficiency and Consistency: Machines wrap faster and more consistently, boosting your overall production efficiency.
  
  
• The ROI Calculator: Calculate your return on investment (ROI) by dividing the projected cost savings by the initial investment. Machines with a quick ROI are often the most attractive options.
  
  

One example of how investing in a stretch wrapping machine can pay off comes from Penn Sheet Metal in Allentown, Pa.

“Manual stretch wrapping of its pallet loads of architectural and roofing components and custom decorative products took 15 minutes per load and required two or three workers,” reports The Fabricator.

The company replaced its manual stretch wrapping processes with an automated orbital wrapping machine and reduced the number of workers required for pallet wrapping from two or three to one and cut wrapping time to 60 seconds or less per load. That adds up to an average of 2.5 hours saved per day or more than 78 eight-hour workdays per year.

Finding the Perfect Match: Choosing the Right Machine

There are two main categories of stretch-wrapping machines:

• Semi-Automatic: Operators load and unload pallets, while the machine handles the wrapping cycle. This option offers a balance between automation and affordability.
  
  
• Fully Automatic: These machines automate the entire process, ideal for high-volume operations with minimal operator intervention.
  
  

Beyond the automation level, consider additional features like pre-stretch capabilities (which optimizes film usage) and top sheet dispensers for added protection.

When choosing a manufacturer, prioritize reputable brands with a proven track record and reliable after-sales support.

Implementing Your New Machine

Once you've chosen your machine, a smooth implementation process is key. This involves:

• Site Preparation: Ensure the designated area has a proper power supply and adequate space for machine operation.
  
  
• Installation: Professional installation by trained technicians is crucial for optimal performance.
  
  
• Training Time: Thorough training for your operators is essential to ensure they can safely and effectively use the machine.
  
  
• Workflow Integration: Plan how the machine will integrate with your existing processes and workflows.
  
  
• Performance Optimization: Continually monitor machine performance and make adjustments to maximize efficiency and film usage.
