Below are twelve misconceptions people have about pallet shrink wrap. Anyone purchasing in bulk should read this before making a purchase. Pallet shrink wrap is a general term, be sure you purchase the products you need.

First, if you are looking for a true pallet shrink wrap, there are thicker pallet heat shrink materials used to shrink and conform to pallet loads of products. The most common of these are pallet shrink bags. Premade bags to fit various pallet sizes are made from a thick polyethylene shrink material to slide over pallet loads of goods to shrink and conform to hold and protect the load. Another less common method for heat-shrinking pallets is using a thick industrial or marine shrink wrap. Most marine wraps are opaque and colored either blue or white. Some new machines and equipment are often wrapped and sent out with this heat shrink material, but it is not often used for wrapping pallet loads of goods.

• 1. The material shrinks down ' The phrase pallet shrink wrap sounds like the plastic shrinks down. Though some 'pallet shrink wraps' shrink down, people often reference the rolls of film wrapped around a pallet, also known as stretch film.

Most people searching for pallet shrink wrap want something they can pull tight around products to hold and unitize during shipment. This material is a stretch film, though people call it shrink wrap. Because the wrap is pulled tightly around the products, it appears shrunk and conformed. The wrap does the opposite and expands to wrap around the skid. With the proper amount of stretch, less film is used, and loads are held tighter together. This form of 'pallet shrink wrap' does not shrink down.

• 2. You must apply heat ' The heat shrink materials mentioned above require heat, but stretch film for wrapping around pallets does not require heat. The proper amount of tension and stretch will appear the plastic shrunken around the shipment.

• 3. Pallet shrink wrap is food grade ' It is tempting to use a wide, thin plastic for food applications. Covering containers as needed or using for direct food contact. We highly discourage any use of pallet shrink wrap with direct food contact. Unless specially made for direct food contact, pallet wrap can not be used touching consumable products.

• 4. Pallet shrink wrap can be stored in the sun ' Made from LLDPE (linear Low-Density Polyethylene), without an ultraviolet inhibitor, the wrap will begin to break down in as little as 30 days of sunlight exposure. The pallet wrap will become brittle and easily pull apart. After enough exposure, the elasticity will be lost, and the film will break down, exposing products. Custom pallet wraps can include UV protection for several months, but it is not a standard feature for most pallet wraps.

• 5. 80 Gauge is the thickness you need ' Any quick search or glimpse at products online will have you thinking 80 gauge is the right thickness. Over the years, it has become the most popular thickness for wrapping loads. It is a versatile wrap but is not always the best choice. Now, most companies are not using a standard 80-gauge pallet shrink wrap.

Though the term '80 gauge' is still popular, many are using an equivalent 80 gauge wrap due to increased petroleum prices. The equivalent materials are thinner than an actual 80-gauge film but are said to have the same holding strength. Thinner yet stronger films can reduce waste and have comparable tension, but they still do not offer the same puncture resistance as a standard 80 gauge.

In addition to the equivalent films, several other thicknesses are available to fit the needs of many scenarios. Lighter materials can protect and wrap half loads or load with less weight. In contrast, thicker 100 gauge can be used for large and heavy pallet loads. There are many different selections available when choosing a pallet shrink wrap; consider other options if applicable to save on money, waste, and possible product damage. View our stretch film thickness chart to get a better idea of the thickness that may work for your needs.

• 6. Pallet shrink wrap is available locally at Home Depot or Lowes ' In a pinch, pallet shrink wrap is available in Home Depot and Lowes by the roll. They are found in the moving section of either store.

Hand-sized rolls with extended cores are most often available. The rolls are perfect for wrapping furniture and bundling boxes and household items. Because of the cost and thickness of the film sold at these stores, we recommend buying pallet shrink wrap in bulk if using any volume. There are more options, better quality, and lower prices for purchasing materials in bulk.

• 7. Hand and machine pallet shrink wrap rolls are the same ' Rolls of pallet wrap are not the same. Larger rolls with thousands of feet of film are made for machine wrapping. Machine pallet shrink wrap has more stretching capabilities. Hand rolls will not stretch more than 150%; machine wrap will expand 250% or more.

This difference in stretch rate is intentional because of the consistent tension a pallet wrapping machine can maintain during the wrapping process. During hand application, users can not pull hard enough as they apply film to reach 250% or more stretch. If a hand roll is used on a wrapping machine, it may not work with the film carriage. If it does work, there will still be waste by not obtaining the total amount of stretch the machine is capable of.

• 8. Pallet shrink wrap can be applied without pulling the material ' The expansion and elasticity of the wrap are what bundle the products. It also gives the material the 'shrink wrapped' look.

Unless using a pre-stretched pallet wrap, users must pull the roll as the load is being wrapped. Without pulling and tightly wrapping the products, they can topple over and move during shipping.

• 9. Pallet shrink wrap is waterproof ' Pallet shrink wrap stretched around a pallet is not waterproof. It can be water resistant, but it is not waterproof. Heat-shrinkable pallet bags are waterproof and an excellent option for moisture protection. For added security when using a pallet wrap, pallet covers and sheeting provide an extra layer against moisture.

• 10. Cheaper the better ' Many equivalent resin mixtures have become popular. They use less material and have more substantial load tension. If a more affordable wrap is an option, we recommend trying a sample to be sure it works. If it does, you can save money and hopefully lower film usage. If wrapping loads with sharp corners and edges, spend more and buy a premium wrap. The additional cost can pay for itself if preventing product loss.

• 11. Pallet shrink wrap cannot be recycled ' It can be recycled, but not often part of local pickup plans. Stretch pallet wrap is made from LLDPE (low-density polyethylene) with a number four recycle code. We recommend calling recycling centers in the local area to find facilities accepting LLDPE.

• 12. Food cling wrap is the same as pallet shrink wrap ' Food cling wrap, often called Saran Wrap, is not the same as pallet stretch wrap. Food cling wrap is usually made from a food-grade PVC material, while pallet wrap is made from LLDPE. Cling wrap does not have the stretch capabilities pallet film wrap does. Pallet shrink wrap is also not recommended for direct food contact. There are many other differences, and they should not be used as substitutions for each other.

Conclusion

Call it pallet shrink wrap, stretch wrap, or cling wrap; the right pallet stretch film can reduce product loss and unitize multiple items. Understanding what many do not realize before making a purchase can ensure you make an informed decision.

Semi and fully-automatic stretch wrappers allow your workers to quickly and safely wrap your skids for shipment. They significantly cut down on manual labor and improve overall efficiencies.

However, determining which type best suits your needs can be challenging. Throughput, load uniformity, space constraints, and budget are just a few considerations that you'll need to evaluate.

Read on to learn more about semi and fully-automatic pallet wrappers and how to decide which one is right for you.

What Are Semi-Automatic Wrappers?

Semi-automatic wrappers require a human operator to drive the pallet onto the turntable and secure the film to the load. 

Want more information on Stretch Foil Machine? Feel free to contact us.

Once the worker pushes the 'Start' button, the machine wraps the pallet according to the pre-selected wrap program.

Several semi-automatic stretch wrapper models can be ideal for low-to-medium operations that need to wrap anywhere from 20 to 300 loads daily. 

For example, the Model UL Ultra-Low enables loading pallets without using a long ramp, thereby saving precious floor space.

Some machines, such as the Handle It® Model 850PS, come with a 250% power pre-stretch film carriage. This feature provides efficient film usage and can save thousands of dollars annually.

What Are Fully Automatic Wrapping Machines?

Automatic pallet wrapping machines offer increased performance and improved efficiency. They're ideal for packaging operations that need to wrap many loads daily. As their name implies, fully automatic wrappers require little human intervention.

The forklift operator drives the pallet onto the turntable, backs away, and then presses a button on the remote control. 

The wrap machine will size up the load via an onboard photo-eye, select the ideal wrapping program, and then secure the start of the wrap.

Once the process is completed, the machine cuts the film and secures the tail end. This makes it a completely seamless operation and allows the operator to stay on their forklift for the entire cycle.

Fully automatic and rotary arm stretch wrappers range in price from $50,000 and up, depending on the project requirements This type of equipment eliminates all of  the labor associated with the wrapping process. Check out our automatic stretch wrapper comparison table to see which model is right for your packaging operation.

Fully-Automatic vs. Semi-Automatic Stretch Wrapper Machine

Semi-automatic and automatic stretch wrappers each have different advantages. For example, semi-automatics provide flexibility for irregular loads and varying pallet sizes with operator oversight. Alternatively, automatics streamline high volumes of uniform-sized pallets.

Semi-automatics require manual loading but enable customizing settings per pallet. Automatics work continuously with no oversight but only suit consistent, standardized pallets. 

Consider your throughput, load consistency, and labor goals when choosing between the two types of stretch wrappers.

In summary, automatic wrappers provide fully unattended operation at high speeds but require a more considerable capital investment. Semi-automatic machines have a lower upfront cost but involve operator labor that can limit throughput.

What Are the Benefits of Automatic and Semi-Automatic Machines?

The main difference between full and semi-automatic pallet wrappers is the manual effort required to operate the machine. However, depending on the model, they both share several benefits, such as:

• User-Friendly Control Panel'The integrated control board enables you to customize up to 18 wrap programs. Users can also control speed, film tension, and view wrap counts.
• Power Pre-Stretch'The power pre-stretch feature stretches the film up to 250% before beginning the wrapping process. This can result in thousands of dollars in film savings every year.
• Optional Scale'You can add a factory-installed optional scale to most machines. This allows for accurate weight and increased freight savings.
• Consistent Results'Achieve uniform wrap quality and pallet stability load after load.
• Increased Safety'Minimize product shift during transport and securely contain loads.
• Labor Savings'Automate wrapping to reduce direct labor costs compared to manual wrapping.
• Maximized Output'Fast operation increases throughput and pallets wrapped per day. 
• Easy Operation'Intuitive controls make machines easy to operate after basic training.
• Enhanced Monitoring'Digital displays provide instant notifications if issues arise.

How to Choose the Right Stretch Wrapper?

Semi-automatic machines provide more flexibility because they are not in line with a conveyor. Automatic machines are more limited in terms of pallet width and depth, and they're typically better for wrapping A-load pallets. 

Automatic stretch wrappers operate without human interaction. If unstable B or C loads shift, they can cause full line stoppages. Alternatively, a semi-automatic pallet wrapper allows the forklift driver to stop and rewrap a shifting B or C load without causing a stoppage.

Several other considerations can help you determine which model stretch wrapper will work best for your packaging operations:

Loads Per Day'How many pallets do you need to wrap daily? Each model varies in how many loads they can wrap per hour or day.

Film Savings'Is saving film a concern? If so, consider models with a power pre-stretch feature to ensure maximum film savings.

Warehouse Space'How much floor space can you allot to a stretch wrapping machine? If available space is a concern, consider the Model UL. It offers a unique frame design that's ideal for smaller areas.

Pallet Jacks or Forklifts'Using manual or electric pallet jacks for loading? We have several ramp options to improve safety and efficiency.

Film Flexibility'Semi-automatic wrappers are ideal for accommodating multiple film types, like colored or printed rolls for seasonal packaging. The operator can switch film types between pallets while automatics are optimized for consistent film.

Integration'Automatic stretch wrappers integrate well at the end of the line, and with conveyor systems, matching high throughput operations. Semi-automatics create a start-and-stop workflow between pallets rather than continuous operation. Consider how wrapping fits your overall automation ecosystem.

Which Stretch Pallet Wrapper Is Right for You?

Fully automatic and semi-automatic pallet wrappers offer many advantages, such as increased efficiency, faster wrapping speeds, and quick ROI. The ideal stretch wrapper should closely meet your workflow, speed, load type, and labor availability needs.
