Muller LCS Raptor Plus - 3d, 240h.jpg

"Pallet wrapper" (aka. pallet wrapping machine) is the common term used to describe the majority of equipment offered for sale by Wrapper Direct.  Other terms interchangeably used are: stretch wrapper (aka. stretch wrapping machine), skid wrapper (skid wrapping machine), and shrink wrapper (shrink wrapping machine).

Pallet wrapping machines are designed to partially or completely automate the process of "wrapping" loads that are on pallets with inexpensive and easy to manage "plastic".  Common terms for this plastic are "Hand Wrap", "Machine Wrap", "Plastic Wrap" and "Stretch Film".

The primary reason for wrapping pallet loads is to keep them from falling apart during transport.  Products contained in this way are much more likely to maintain load integrity during transport, and arrive intact at their destination ... reducing or eliminating transportation damage.  In fact, many transport carriers will not accept pallet loads unless they are wrapped.

Pallet Load, Wrapped.jpgOther advantages of wrapping include:

  • theft deterrence
  • dust protection
  • weather proofing

Advantages of using a wrapping machine include:

  • help alleviate ergonomic and safety concerns
  • provide wrapping consistency (vs hand wrapping by operators)
  • manpower savings - semi-automatic models do not require the active participation of the operator throughout the whole wrap cycle, allowing him/her to work productively elsewhere while the load is wrapped automatically
  • cost savings - a wrapper with a pre-stretch film dispenser, keeps film costs low, and maintains the quality load retention that only pre-stretch can provide and helping to ensure that shipped loads arrive intact (see FAQ - Pre-stretch vs Conventional Film Dispensers)
  • process efficiencies - fully automatic models (with conveyors) automate the packaging process such that an operator is not required at all except to replenish film when the machine wrap runs out

What is Pre-stretch vs Conventional Stretch?

Mach 1 E-STRETCH FILM CARRIAGE - 240h, 3D.jpgNon pre-stretch film dispensers typically use hand-wrap, machine wrap, or pre-stretched films and can stretch the film off the roll up to an absolute maximum of 100% of the film's original length. (Although this level can rarely be accomplished without pulling the load off the table or damaging the product.)  It emulates the application of common hand wrap by an operator.  This type of stretching provides only "post-stretch" because all of the stretching of the film occurs outside of the film dispenser.

Some applications call for the application of a "wrap" that is not stretchable, and this conventional film dispenser is preferred.  An example of this is the application of "netting" used in the fresh produce food industry where air flow through the product load is important to negate condensation while preserving load integrity.


Phoenix PLP-2150 - Phoenix Powered Pre-stretch Film Carriage - 20 inch.jpgMost pallet wrapper models (regardless of manufacturer) are equipped with a pre-stretch film dispenser.  Also known as a "powered pre-stretch film carriage", a pre-stretch film dispenser pulls the specially formulated "machine wrap" off of the roll and stretches it within the film carriage itself using two rollers (powered by a motor) that are running at different speeds.  This effectively takes 1 foot off the roll and turns it into 3 feet coming out of the carriage.  This feature of stretching the film in the carriage, instead of after it, is the root of the name "pre-stretch" (vs. "post-stretch").

The differential in these roller speeds is expressed as "pre-stretch level".  In the above example of 1 foot becoming 3 feet, the pre-stretch level is 200%.  Some film carriages are geared to increase this level up to ~300%, albeit at this level specially formulated films may be required.  Most film carriages on new wrappers today are geared between 200% to 250%.

With a pre-stretch film dispenser, the "post-stretch" is still available, and is controlled by the operator using a control.  It can be as tight or as loose as is necessary.

Mach 1 X-STRETCH Film Carriage (v2).jpgThe primary advantage of pre-stretch is the film savings it provides.  The conventional industry wisdom is, that in comparison to hand wrapping, when wrapping between 25 to 35 loads per day, a machine with pre-stretch can pay for itself in film savings alone in approximately two (2) years.  If you are using hand wrap now, you could look at your current "hand wrap" film costs and expect that these costs would likely be reduced by 30% to 50%, with a pre-stretch wrapper.
The secondary advantage of pre-stretch is better load containment.  Simply, a better wrapped load!  This comes from the fact that the film has elastic properties.  Even though the film has been stretched to 3+ times it's original length and applied to the load, over time it contracts a little, so that as the wrapped load sits there in the next few hours to a couple of days, the wrap slowly tightens on the load, securing it even better than it was when originally wrapped!  Some users have a machine with pre-stretch, even though they do not have high production volumes, simply because the combination of the consistency of a machine wrapped load (vs hand wrapping by operators), with improved load retention (provided by pre-stretch) addresses their issues of loads falling apart in shipment.

What are the power requirements for semi-automatic pallet wrappers?

Printer Friendly Page

The power supply rating of almost all semi-automatic pallet wrapping machines is 110 / 120 VAC, 15 AMPS, 60 Hz.  The power plug used is the same standard 120 VAC plug / receptacle found in your home and office.

The use of a standard plug is especially useful for turntable style wrappers which are fork lift portable.  This allows the machine to be plugged in wherever it is convenient for your wrapping process in your warehouse or shop floor. 

Please consider that for a brief moment, at the start of a wrap cycle, the machine could actually pull close to the 15 AMPS it is rated for.

We recommend that the wrapper should NOT SHARE a 15 AMP circuit with other high current demand devices (eg. air conditioner, space heater, hot plate, etc.).

For truly trouble free operation, the factory recommends dedicating a 20 AMP circuit to the machine, but your needs will dictate what is possible.

We also recommend avoiding the use of a long extension cord because the line voltage loss at 110/120 VAC over an extended distance can be significant and result in issues.

What film (machine wrap | stretch film | plastic wrap) is needed for a wrapper with a pre-stretch film carriage?

Printer Friendly Page

All pallet wrapping machines with pre-stretch run industry standard machine film; typically "Machine film, 20" Roll width, 10" Diameter".

An ever diminishing number of machines use 30" Roll width film.
There are only two (2) industry standard sizes for film, 20" and 30".

The thickness of the film is typically expressed as 'Gauge' (Ga), with thinner film being lower numbers, eg. 40 Ga is thinner than 90 Ga.

Typically, a 50 or 60 Ga film is used when load retention is less important and you want more of a dust cover than a secure wrap.

80 to 90 Ga is typically used when the loads are heavier and load retention is more important.

If you need both light and heavy application of film for different load types, you can use a lighter film, and simply increase the number of wraps on loads that require better retention.  It takes longer to wrap the heavy loads, but saves you from having to change your film roll each time you have different load types.

What environment is this equipment designed to operate in?

All products are designed for operation in a typical warehouse environment:

  • dry
  • clean
  • heated

Options may be available to adapt these machines for operation in other environments:

  • cold / freezing
  • wet
  • dusty
  • custom

Operation of these machines in conditions for which they were not designed might reduce the life expectancy of the machine and/or negate the warranty.

Can something that is not on a pallet be wrapped?

Mach 1 SONIX LPX Window Wrapper - 3D, 240h.jpg

Many other types of automated wrapping are also possible ... even though the product is not on a pallet.

"Door and Window" wrappers are a common variant of the typical turntable style semi-automatic machine when coupled with a load holding top platen.


Mach 1 Automatic Orbital - 3D, 190h.jpg

Other things such as:

  • bundles of pipe
  • lumber
  • plastic extrusions
  • doors
  • windows

can be wrapped with a horizontal ring wrapper (aka. orbital wrapper).

Octopus Cocoon Wrapper - 3D, 240h.jpgLarge coils and rolls of product, such as:

  • steel coils
  • paper tissue
  • rolls of material

can be cocoon wrapped in a process that combines a stretch wrapper with a load roller.


What should my pallet | skid | stretch | shrink wrapper settings be to properly secure my loads for shipment and reduce my stretch film costs?

Printer Friendly Version


  • To properly secure the load for transport (keep loads from falling apart in the truck)
  • To provide protection against dirt and moisture (helps to keep products clean and dry)
  • To provide theft deterrence (make it harder for people to steal products)
  • To minimize packaging costs (save money on the cost of film by preventing needless over wrapping of your loads)


Quick Steps:

  1. Start a wrap cycle.
  2. Adjust the turntable speed to approximately 2/3 to 7/8 of maximum speed.
  3. Adjust the film force to the desired tension.
  4. Adjust the film carriage up (raise) speed of the film carriage until there is a film overlap of approximately 4" (100 mm).
  5. Adjust the overwrap height to make the film fold over the top of the load and create a band around the top of the load that is approximately 4" (100 mm) wide.
  6. Set the top wraps count to at least two (2) revolutions.
  7. Adjust the film carriage down (lower) speed to a fast rate.
  8. Set the bottom wraps count to at least two (2) revolutions.
  9. Repeat wrapping loads as necessary until satisfied with all settings.

What do I need to consider when receiving a machine?

Printer Friendly Page

  1. Most wrappers are forklift portable from one end. (Some from both ends.) This facilitates shipping of the machine and easy movement of the machine throughout your facility as your needs dictate. A 3,000 lbs capacity fork truck, with 4 wheels, is recommended.
  2. Please check the size of the shipping / receiving door, and any other doorways the machine must pass through to its final destination to ensure they are large enough to accommodate. The shipping dimensions of the machines vary. Please check your documentation or speak to your representative for details.
  3. For turntable style wrappers it is important to ensure the machine is placed on a flat and seamless (crack-less) section of flooring to ensure even distribution of load weight and to help prevent structural issues.
  4. For low profile turntable wrappers with a ramp, the ramp ships with the machine, usually stacked on the turntable, and must be manually installed. Dependent upon the machine model, and your installation needs, the drilling and tapping of bolt holes may be required. Unless otherwise arranged, the customer is responsible for this installation.

What is the business case for leasing or financing?

Printer Friendly Page

Would you pay staff a year's salary in advance? Would you prepay a supplier years worth of product before you used it?
The smart business move is to pay for things while you use it, not before you use it.
1Instead of pre-paying for equipment out of your capital and then waiting for your return on investment over 2, 3 or 4 years, lease the equipment today so you match your monthly payments to the revenue generated by the equipment or software.
Now is the time to use leasing because rates are at historical lows. This helps you realize a clear ROI on any equipment investment.
As our economy begins to open up, economists have cautioned inflation is unavoidable. Leasing is your best bet to hedge against inflation. Lock in at current low rates, and get the equipment you need to grow your business.
Conserve your capital and take advantage of the market conditions that make leasing a clear winner!

Mach 1 Packaging specific questions

What is the standard sized heavy duty ramp option?

This option allows loading and unloading of the product from the turntable, without the need for a fork lift truck.

This standard sized heavy duty ramp is suitable to allow operators to load and unload the wrapper turntable with a manual pallet truck, pallet jack, pump truck, jigger, or similar pallet transportation device.

NOTE: Fork lift truck loading and unloading is still possible from either of the other two sides.

Mountable in the position appropriate for your needs, holes are pre-drilled to accommodate the standard three (3) ramp positions used by most applications.

If a non-standard ramp position is required, the drilling and tapping of holes in the required position is possible.

The dimensions of this ramp is 12" flat, 48" incline, by 48" wide.

Fork lift truck loading and unloading is still possible from either of the other two

What is the larger sized heavy duty ramp option?

This option allows loading and unloading of the product from the turntable, without the need for a fork lift truck.

This larger sized heavy duty ramp supports loading and unloading with all of the devices noted in the "standard sized ramp", plus, it supports the use of powered-walkies or transpallets that have a longer wheel base than the traditional hand pump trucks or pallet jacks.

NOTE: Fork lift truck loading and unloading is still possible from either of the other two sides.

Mountable in the position appropriate for your needs, holes are pre-drilled to accommodate the standard three (3) ramp positions used by most applications.

If a non-standard ramp position is required, the drilling and tapping of holes in the required position is possible.

The dimensions of the ramp is 24" flat and 48" incline by 48" wide

How do I attach the ramp to my Mach 1 low profile pallet wrapper?

Printer Friendly Page

  •  The "Ramp" typically ships on top of the wrapper turntable.
  •  A "Ramp mounting bracket" is also supplied.
  •  There are four (4) threaded holes in the pedestal base of the turntable support column.  There are two (2) "Set screws" shipped in 2 of these 4 holes.  Remove these "Set screws".
  •  Attach the "Ramp mounting bracket" to the pedestal base of turntable first (using the "Set screws"), in the position appropriate for your needs.  (The holes are drilled to accommodate the standard three (3) ramp positions used by most applications.)
  •  Then, position the "Ramp" close to the turntable, leaving approximately a 1/4" to 3/8" gap between the turntable plate and the ramp.  (Use a screwdriver or crowbar to maneuver the ramp.)  Attach the "Ramp" to the "Ramp mounting bracket" with bolts, fixing it in place, and maintaining a proper gap.
  • Test the turntable rotation and ensure there is no binding.  Adjust if necessary.

The loading ramp must be attached to the wrapper’s base or anchored into the floor in such a manner that it will not be in contact with the rotating turntable.  A 3/8” gap between the two is advisable.  Furthermore, the ramp must be leveled at least 1/8” below the turntable’s surface to prevent rotating pallets from rubbing on it.

Recommended Tools:  Socket wrench; 9/16" Socket (long); Extension; Large flat head screw driver (or small crowbar)

What is the height detection photo-eye upgrade option?

This option addresses potential issues with the industry standard photo-eye that detects the top of the loads, affecting the auto height functionality. 

If some of your loads are particularly bright white, shiny, or deep black (like tires), the standard photo-eye might not reliably detect the top of the load. 

If your loads loads consist of cardboard boxes and otherwise unremarkable packaging, you likely don't need it.

What is the extra film carriage idler roller option?

This option facilitates wrapping of smaller loads on standard machines, or the wrapping of smaller (and standard) sized loads on extended base or split base wrappers. 

Applicability is dependent upon the particulars of the application. 

Without this option, the film might not pull the dancer bar roller (which controls film feed) at an angle sufficient to activate it, resulting in film feed issues.

What is the independent settings switch for 3 load types option?

This panel mounted 3-position selector switch provides operators a very quick and easy means to switch from one set of wrapping parameters to another.

Useful if you have different load types that need to be wrapped in a particular way (for example with  differing number of top and bottom wraps, differing up or down speeds, a different amount of overwrap, etc.)

Mach 1 DIGI-TECH Control PanelThe control panel is very user friendly, and quickly allows changing any wrap parameter, but if you are changing more than one or two things from one load to the next, expecting your operators to do this on a consistent basis may be a challenge. With this option, changing from one wrapping 'recipe' to the next is as easy as flipping a switch to one of three positions before hitting the start

This is a very inexpensive option and may be worth obtaining just as a hedge against potential future wrapping needs, even if you don't need it now.

Allows ALL machine functions to be set differently for up to 3 different load types:

Including independent settings for:

  • turntable speed
  • carriage up speed
  • carriage down speed
  • film tension
  • and ALL other control system parameters.

What is the base mounted adjustable roping bar option?

This option allows the precise positioning of the lowest level the film is applied to the load / pallet. 

The PRIMARY purpose of this option is to wrap loads without wrapping in the pallet. Without this option the sides of the pallet are wrapped, creating a single pallet supported load, however, when picking up and taking the load away, the film over the sides of the pallet could be pierced, affecting the quality of the load / pallet unitization. (The affect of pierced film is often inconsequential, but in certain applications it is an important consideration.) 

The SECONDARY purpose of this option is to create a "film rope" around the sides of the pallet (at the base of the load) that increases the reliability of holding the load to the pallet, while at the same time positioning the film so the load can be removed without piercing the film. 

At time of order, please advise the stated intent, a) to prevent wrapping in the pallet, or b) to create a 'film rope' that enhances load / pallet unitization. This will ensure a properly configured roping bar is supplied.

NOTE: Most customers successfully wrap their loads without this option, but in certain applications it is a benefit.

What is the automatic end of cycle film cut option?

This option automatically breaks the film at the end of the wrap cycle, providing an opportunity for a forklift driver to take the load away without needing to get off his forklift truck simply because he has to cut the film. 

Useful in high production rate environments where minimizing operational steps is important to increase efficiencies. Works best when pallets are of similar size, A or B type, square or rectangular (not round) and 40" x 40" or larger

This option does not seal the film tail to the load or secure it in any way. The operator is still responsible to attach the film to the load at the beginning of the wrapping process.

What is the "Starter Film Package" option?

This option is for customers who do not already have a pallet stretch wrapper and do not have a supply of machine stretch wrap film on hand. 

This is the same film used by the factory to setup and test the machines. 

It allows you to run the machine upon receipt and provides a point of comparison for machine wrap to be supplied by your film supplier before committing to a whole skid of film that might not meet your needs.

General purpose, high performance (supports higher pre-stretch levels).

  • Mach 1 semi-automatic wrappers using the "DIGI-TECH control unit", including the following models:
    • Mach 1 ROCKET LP-HP
    • Mach 1 ROCKET LPX-HPX
    • Mach 1 SONIC LPX-LPS-HPX


  • Turntable rotation, film carriage up / down, or pre-stretch (film feed) does not function.


  • Fuse replacement.


Mach 1 Packaging has given careful consideration to the mechanical and electrical design of these machines, ensuring that the machine will electrically protect itself from severe electrical damage in the case of an electrical overload or short.

It is fortunate that external factors tend to be the cause of drive board issues the majority of the time, and that correction of most drive issues is the simple replacement of a blown fuse.

Scope:  This document describes the procedure to resolve the most common cause of a drive board issue ... a blown fuseIt is not a comprehensive trouble-shooting guide that deals with other solutions to drive board issues.  See the ADDITIONAL SUPPORT section of this document if fuse replacement does not rectify the issue.

Caution:  Take steps to ensure that any potential causes of the issue are rectified before proceeding.


Blown fuses are the the result of electrical overload conditions that typically occur due to factors external to the machine.


The machine is rated to operate at 110/120 VAC, 15 AMPS, 60 Hz.

Potential causes of power supply issues can be:

  • electrical interference or current draw from other devices on the same supply circuit
    • under normal operating conditions, at the start of a wrap cycle, the machine can draw close to the 15 AMPS it is rated for
    • we recommend that the wrapper should NOT SHARE a circuit with other high current demand devices (eg. air conditioner, space heater, hot plate, etc.)
  • improperly sized or damaged power feed wiring
  • poor quality power feed wiring
  • low power supply voltage
  • high power supply voltage
  • running the machine on a long or insufficiently rated extension cord


  1. measure the supply voltage at the plug where the machine is connected
  2. measure the supply voltage both when the machine is at rest, and when it is running a normal wrap cycle with a load on the turntable and the film attached to the load


Potential causes of mechanical binding or blockage can be:

  • the turntable physically contacting or binding on something
    • loading ramp (ensure sufficient clearance between turntable and ramp)
    • poor condition skids over-hanging the turntable and contacting the turntable surround or ramp
    • improperly centered skids/loads contacting the film carriage
    • skids/loads contacting nearby adjacent objects
  • excess film caught under the turntable and getting caught in the turntable casters
  • starting a wrap cycle without backing the forklift out from the load
  • "joy-riding" on the film carriage
  • machine film "wrap up" on the pre-stretch rollers


Determine that the problem could be a blown fuse in one of the drive boards!

At least one of the following conditions will be true:Mach 1 SONIC LPX - CONTROL PANEL and ACCESS PANEL CLOSED

  • the machine display will power up when the machine power is turned on
  • manual control [jogging] will function as expected
    • turntable rotation
    • film carriage up and down
    • the film carriage will feed film manually (TIP: after pressing the PAUSE button to enable the pre-stretch)
  • the machine will start a wrap cycle, however, one of the above functions (turntable, film carriage up/down, or pre-stretch (film feed)) will not work


1. Ensure that the power to the machine is off. Preferably unplug the machine, or turn off the circuit breaker (or remove the fuse) at the panel supplying power to the machine, or ensure the main power switch is off.

2. Remove the control panel access plate that is located at the same height, but at the rear of the tower. Use a hex key to remove the machine screws. (The plate is not otherwise attached to the tower, but sometimes the plate will need to be pried away from the tower with a screw driver.)

Mach 1 SONIC LPX - PANEL OPEN3. Once the control panel access plate is off, you will see the three drive boards to the right. Each are three slightly different versions of the same DC drive board. On each, you will see a fuse, the same kind commonly found in vehicles.

4A. The pre-stretch (film feed) drive board is the one at the top.

4B. The film carriage (up / down) drive board is the one in the middle.

4C. The turntable drive board is the one on the bottom.

5. A factory supplied spare fuse, in a bag (or attached with silver duct tape), can be found at the bottom of the panel. The same fuse can typically be used in all three of the drive boards.

6. Replace the fuse in the suspect board.

7. Power up the machine and test for functionality.

8. Replace the control panel cover.


We encourage stocking a small supply of extra fuses to minimize downtime should another blown fuse issue occur.

Fuse details:

  • The fuse is MDA-xx-R.
  • XX stands for the amperage -> MDA-8-R and MDA-10-R

Please do not use any other value fuses in these machines unless verified with the factory design engineer.

The motor size dictates the fuse size:

  • 0.50 HP -> 8 amp
  • 0.75 HP -> 10 amp

(The standard motor size in most applications is 0.50 HP.)


Should the above procedure not rectify the issue with the machine, please contact Wrapper Direct, or technical support at the factory for additional assistance.
