Shrink Wrap Machine: The Ultimate Guide

In this guide, you will find all information about shrink wrap machine. Whether you want to learn about design, features, specification, types or working principle – everything you are looking for is right here.

What Is A Shrink Wrap Machine?

This is a machine that uses heat applied to a thin plastic film wrapped around a product to shrink it and package the product.

The item is covered by the plastic film and then passed through an oven or heat tunnel to shrink.

They can wrap various products such as blister packs, pallets and tubes, cups or trays and a variety of other products.

The Shrink Wrap Machines come in a wide range of specialized designs for different industrial applications.

Applications Of A Shrink Wrap Machine

Shrink Wrap machine has many applications in a wide spectrum of industries with new segment applications coming up every day. Some of these applications include:

Wrapping Packaged Foods

A rapidly growing trend in the current food industry is the method of multi-packing food sold at wholesale stores.

Shrink Wrap gives them an edge like prolonged shelf life, tamper proof and an improved visual appeal.

Since they can withstand extreme temperatures and toxic conditions, they are used to wrap frozen foods and other refrigerated products like ice cream.

Wrapping Printed Materials

This is the largest market segment in Shrink Wrapping and was initially dominated by the use of PVC films.

The inclusion of polyolefin with low shrink force has greatly reduced the dominance of PVC in this market.

This segment includes shrink wrapping ranging from large form stationery producers to small scale shop printers.

Wrapping Pharmaceutical Packages

The Pharmaceutical market has tremendously grown impelled by the need to have tamper-proof packages.

Shrink Wraps can also reduce the overall product cost by multi-packing it compared to other packaging options like PVC shrink bands.

Wrapping Sporting Goods, Games And Toys

Shrink Wrapping these products enhances their integrity and gives them an appealing visual effect to the customer.

Plastic model toys various types of sport equipment, puzzles and games all profit from the shrink wrap film security.

Wrapping Houseware And Hardware

Shrink Wrapping is applied to a very wide variety of home appliances and hardware parts and tools. They range from plastic bowls, cutlery sets and assorted tools which are shrink wrapped instead of the conventional blister and corrugated packaging.

Wrapping CD’s And Video Tapes

These two products are packaged using some kind of film overwrap with video tapes primarily shrink wrapped.

Though CD’s normally use tuck and fold as a non-shrink process, more producers are resorting to shrink wraps as their equipment is being updated.

Working Principle Of A Shrink Wrap Machine

The operations of a Shrink Wrap Machine are majorly based on loosely wrapping a plastic film on a product or a number of products as one.

The product is then conveyed to a heating tunnel where the wrap is heated and shrinks to tightly fit the product creating a protective barrier.

This is the basic principle of operation but the mode of operation varies depending on the type of Shrink Wrap Machine.

They may be manual, semi-automatic and fully automatic with different working mechanisms.

Types Of Shrink Wrap Machines

Shrink Wrap Machines are available in a wide range of types depending on the packaging operations they are required to carry out. They include:

Single Reel Shrink Wrap Machine

It involves the use of a single reel that is that is placed around a product overlapping underneath after it has been stretched and cut to fit.

Technically, the film is fed on the conveyor with the product placed on the film then folded, sealed then heat applied to shrink it.

single reel shrink wrap machine

This type of Shrink Wrap Machine is mostly applicable in for wrapping multipacks which mostly require a printed film.

They are very precise when positioning the printed area of the eventual product being wrapped.

Double Reel Shrink Wrap Machine

In this type of Shrink Wrap Machine, two rolls of film are used simultaneously giving a strongly wrapped product.

They are mostly used to wrap very large products such as doors, pallets and multipacks of huge products.

The products can be wrapped much faster than the single reel machine with stronger film wraps produced.

They are recommended low to medium product output with packaging requests that are straightforward.

Side Seal Shrink Wrap Machine

The Side Seal Shrink Wrap Machine extremely versatile enough to wrap products of literally any length.

The reel feeds the shrink wrap film around the product with a loose tube formed around the product length.

Oversized Shrink Wrapper

The products are then sealed and separated by cutting and the conveyor used to forward them to the heating tunnel.

Heat is then used to tightly shrink the wrap around the product.

L-sealer Shrink Wrap Machine

This wrap machines contain dual sealing bars that have been positioned in a backward L shape.

A pocket is formed on the crease created by the shrink film when it is folded along the sealing bars and products placed.

After placing the products on the crease, the shrink film is sealed on the remaining three sides.

The products are then conveyed to the heating tunnel where the film is heated to produce a tight fit around the product.

Components Of A Shrink Wrap Machine

A Shrink Wrap Machine has the following components:

  • Aluminum Hot Sealing Jaws: they use heat to apply pressure on wrapping films to separate products after wrapping.
  • Machine Engine: mainly composed of motors powered from a mains source of electricity.
  • Conveyor System: has a conveyor belt with rollers and powered by a motor to convey products in the wrapping process.
  • Heating Tunnel System: contains heating devices placed over conveyers and can be either hot air, steam or infra-red shrink tunnels.
  • Thermostat: used to regulate the heating temperature when shrink wrapping the product.
  • Cooling Fan: heat is generated when sealing and the fan is used to cool down the machine and product after sealing.
Manual Vs Semi-Automatic Shrink Wrap Machine

A Manual Shrink Wrap Machine requires a dispenser for the film, a heat gun that is manually operated and a sealing bar.

The reel feeds the film onto a level surface and the product positioned on the film with a loosely placed fold of film over it.

A heated sealing bar is used to seal the film seals and a manual heat gun shrinks the film on the product surface by passing over it.

Operational costs are significantly low with a Manual Shrink Wrap Machine but with limited output.

In a Semi-Automatic Shrink Wrap Machine, the dispensing reel machine-feeds the film into a platform.

 The product is then positioned on the film surface which is folded loosely on the product after being cut to size.

An airtight seal is made using a sealer and the product taken to the heat using rollers or conveyer belts tunnel to shrink the wrap.

The products are then moved to a receiving surface from the heat tunnel using the same conveyers

Recyclable Shrink Vs Compostable Shrink Wrap Film in Shrink Wrap Machine

Recyclable Shrink Wrap

Recyclable Shrink Wraps are generally manufactured from polyethylene that has a very low density (LDPE).

Facilities have been set up in most cities to accept consumer waste composed of LDPE with others also accepting polyolefin shrink wraps.

Nevertheless, it is not possible to recycle shrink wraps that have been used on sanitation products or healthcare products.

This will also include shrink wraps used around hazardous waste as containers and those contaminated with organic waste.

Compostable Shrink Wrap

These are shrink wraps that have been engineered to decay in composting systems found at home or in industrial set ups.

Such composting systems must have conditions like high levels of humidity, raised temperatures

and high levels of oxygen.

Such necessities require that the shrink wrap recycling stream be separated from the recycling stream of other compostable plastics.

L-Bar Heat Sealer Vs I-Bar Heat Sealer In A Shrink Wrap Machine

The Shrink Wrap Machine part responsible for cutting and sealing the wrap film on a product after heating is called the sealer.

The various forms are the floor standing sealer, an I/L table-top sealer or a sealing wand that is hand-held.

The two major types of Shrink Wrap Machine sealers are the I and L sealers which offer different merits when used. They vary as follows:

I-Bar Heat Sealer

This type of Shrink Wrap sealer is commonly used in systems that operate manually during the wrap shrinking process.

The name originates from the heating bar/element shape that resembles the letter “I”.

This kind of Shrink Wrap Sealer is recommended for sealing products that are small or medium-sized.

Since the machines they are used in are manual, they are typically hand-operated by lowering it when sealing the film.

L-Bar Sealer

The application of this type of wrap sealer is mostly in the fully automatic and semi-automatic Shrink Wrap Machine.

The heating element resembles the letter “L” with a very efficient sealing technique and fast action.

It is normally operated by means of a foot pedal or a switch when used in a semi-automated Shrink Wrap Machine.

The sealer is electronically controlled I a fully automatic Shrink Wrap Machine ensuring safety and flawless operations.

Benefits Of A Shrink Wrap Machine

The Shrink Wrap Machine has various advantages that include:

Increase In Storage Space

Due to their size, Shrink Wrap Machine fill up very little space thus freeing up extra storage space for other products.

They are smaller than the old-fashioned packaging equipment and are very lightweight.

Increased Marketing

The use of Shrink Wrappings on products is just not eye-catching but greatly assists in marketing the product and company.

The printed wraps spread and improve the product awareness and can also increase the loyalty of customers.

Apply Unique Packaging Choices

Some companies prefer to transport their products cold and the Shrink Wrap equipment is the best choice.

Because of its tight seal and resilience to environmental damage, the plastic wrapping makes refrigeration suitable for the products.

Cost Efficient

The Shrink Wrap technique requires around 75% less material compared to older packaging techniques and corrugated products.

Less material required with minimal space occupied means savings are increased and with easy end-product disposal.

Protection From Damage

The Shrink Wrap is highly efficient in protecting products against harsh environmental damages like humidity and dirt.

It also extends the shelf life of products like perishable foods that would have otherwise gone bad.

Tamper Proof

Once the Shrink Wrap has been applied, both seals are hold the product shape in its position and any tampering can be easily noticed.

Many pharmaceutical and food companies are shrink wrapping their products to enhance quality and credibility.


The major thing differentiating Shrink Wrap Machine from other packaging systems is the ability to package any size of product.

From small electrical wires to hardware and game pieces and freight carried on trains and trailers, Shrink Wrapping is applied in all these.

Choosing A Shrink Wrap Machine

There are several factors that should be put into consideration when selecting a Shrink Wrap Machine. Some of them include:

The Product To Be Shrink Wrapped

There is a very wide variety of shrink wrap films that are made for specific products and applications. An appropriate shrink wrap that perfectly suits the product should be selected to avoid shrink wrap issues that may arise later.

Available Premise Space

Shrink Wrap Machines are available in various shapes, sizes and mobility and should be selected depending on premise size.

If the workspace is small with minimal products to package, then a compact I-bar sealer that straight is recommended.

Integration And Future Expansion

You should consider the possibility of the Shrink Wrap Machine to be integrated into an existing packaging production system.

Not all Shrink Wrap Machines can be integrated and add-ons like conveyors will have to be selected for suitable and flexible packaging.

Shrink Wrap Machine Packaging Speed

The speed of Shrink Wrapping systems varies widely in different machines so the wrapping output needs should be identified before purchase.

Some wrapping machines can pack many products per hour while others can do the same number of products in a minute.

Degree Of Automation

The Shrink Wrap Machine comes in different levels of automation depending on the cost and preference of the client.

The available choices include fully automatic wrappers, semi-automatic wrappers and manual wrappers.


The Shrink Wrap Machine should be selected based on the budget available but without compromising the quality and standards of the product.

A variety of manufacturers are available with varied prices for the same Shrink Wrap Machine.

Maintenance Procedures Of A Shrink Wrap Machine

Shrink Wrap Machines are very important packaging tools and their maintenance is vital for efficient operations.

Some of its maintenance procedures include:

Regular Machine Inspection

After every daily operation, a wire brush and film release agents should be used to clean the sealing blades.

Lubricant should be regularly applied to all the moving parts with regular inspection to replace ageing parts on time.

Environmental Conditions

The Shrink Wrap Machine should optimally be operated in an environment having a temperature range of about 10°C – 50°C.

Relative humidity should not exceed 85% with no dust, explosive hazards or corrosive gas in the vicinity.

Electricity Environment

When the Shrink Wrap Machine operations are starting, the operating room should first be ventilated before the machine is energized.

After clearing the operations and the machine shut down, the electricity must first be cut off and then any form of gas shut down.

Proper Cleaning

Proper cleaning procedures should be observed such as keeping the heating and silica gel strip always.

Any foreign matter on the them must be removed immediately to prevent negative effects on the quality of the seals.

Power Numerical

The power ratings on the machine nameplate should be adhered to, to prevent burn out of the machine components or internal wiring.

The input power in actual operation should be equal to or larger than the rating marked on the nameplate instruction.

Machine Placement

The Shrink Wrap Machine should be installed horizontally to ensure the heat pipes are operating normally and prolong service life.

If the angle of installation of the machine is not correct, then the conveying belts and the center will be deviated.

Infra-Red Shrink Tunnel Vs Hot Air Shrink Tunnel In Shrink Wrap Machine

The heating tunnel of a Shrink Wrap Machine is a heating device positioned above the conveyor with a heat chamber forming part of the wrapping machine.

The difference between the Infra-Red Shrink Tunnel and Hot Air Shrink tunnel is as follows:

Infra-Red Shrink Tunnel

Heat in this type of tunnel is radiated using heat bulbs and in terms of response time can be classified as one of the most aggressive shrinking device.

The major advantage over the Hot Air Shrink Tunnel is consistency in heat levels and is very fast.

Its major demerit is its reduced ability when shrinking film on products closely packed together or having complicated shapes.

They also have intense heat emission thus not recommended for packages gentle or mild heat when wrapping.

Hot Air Shrink Tunnel

This is the most common shrinking device and shrinks the wrap film around a product using hot air. It is easy to use and very reliable with varied temperature range settings so that heat can easily be customized for individual needs.

Troubleshooting Shrink Wrap Machine

A Shrink Wrap Machine has a variety of uses that include product protection from moisture and dust, adding retail appeal and environmental impact reduction.

However, certain problems may arise that can affect the performance and quality of products wrapped.

Some of the problems and their solutions include:

Unfinished Cut-Offs or Jagged Seals

Seals that appear jagged, incomplete or torn is a clear indication that the seal temperatures in use are too low.

It is recommended that the heat be adjusted upwards in increments of 25°F until the seal film attains a clean seal.

Shocks Created By The Shrink Wrap Machine

When Electro-Static Discharge (ESD) occurs, it is a sign that static electricity is present on the machine.

The ESD can also bring about other issues related to film tracking, tension on the film or matted film.

This issue can be fixed by using three-prong plugs to ground the equipment and connecting the frame to a grounding source.

To prevent static and film drag from the polished surfaces, they can be roughened up using some sand paper.

Weak Pinholes or Seals

When tiny brittle seals recurrently appear in open areas and pinholes, it is most likely because the seal temperatures are too high.

Reducing the seal temperatures will prevent the film from crystallizing around the seal area.

Flat Films Unable To Come Off The Roll

This phenomenon is called “blocking” whereby the flat film layers tend to stick together due to extreme storage temperatures.

The film storage temperature must be maintained around the normal room temperature to prevent its layers from fusing.

Damaged Or Curled Products

An extremely aggressive film force or improper tunnel parameters often result in the product being damaged by the film.

To counter this, a reduction in air flow and temperature, increase in conveyor speed or wrapping more film on the package might help.

If these do not work, then a film with lower energy should be considered since its shrink force will be a bit gentle.

Split Seals

This is usually caused by a bad film roll or when the film is too thin or the film have unwanted holes or perforations.

The clamp should be assessed to ensure that it exerts the correct amount of pressure evenly and the sealing wires cleaned.

Limitations Of Shrink Wrap Machine.

The Shrink Wrap Machine has the following limitations:

i. The polyolefin used in the Shrink Wrap Machine is a bit expensive as opposed to the PVC film.

Some applications may also require it to be perforated to evade bumpy surfaces and air bubbles.

ii. Some wrap films like Polyethylene are not as clear compared to other films and with a low shrink rate of about 20%.

In terms of Cost, Polyethylene is also costlier than other films.

iii. Extremely high sealing temperatures makes the wrapping film wrinkled and soft.

When the temperatures are too cool, the film wrap becomes brittle and hard.

iv. Many countries are now banning the use of polyvinyl chloride (PVC) films due to their toxic byproducts and chemical composition.

This means that Shrink Wrap Machines in such countries cannot use PVC for wrapping products.

v. Shrink Wrapping using PVC produces strong, toxic odors therefore should be done in well ventilated areas.

Stretch Wrap Vs Shrink Wrap

Stretch wrap and shrink wrap are mostly mistaken to be the same since they are both made of plastic material.

However, there are major significant variations between these two methods of packaging.

Stretch wraps made from polythene are a stretchable and thin plastic film normally used to seal products in pallets and not the products themselves.

Tension is applied to the stretch wrap as the film gets wrapped around the pallet extending its length by around 800%.

A constrictive force is created around the product by the tension making the product to very stably hold in its place.

Stretch wraps have many varieties like hand stretch and machine stretch which has cast stretch, blown stretch and pre-stretched films.

On the other hand, Shrink Wraps are plastic films that are used in packaging the actual product such as toys and frozen foods.

A protective wrap that is tight is created around the product being packaged when the plastic shrink after heat is applied to it.

Shrink Wraps have two collective types that are polyethylene which is thick but with a lower clarity making it durable.

The other is polyolefin which is versatile, has great clarity and is highly durable making it suitable for freezer applications.

Eliminating Static Buildup In Shrink Wrap Machine

Many shrink materials are prone to static hence static build up is a major contributor of many Shrink Wrapping issues.

To find out if the machine has any form of static-cling, a piece of shrink film is held an inch or so above the machine.

If the shrink film piece is attracted to the machine, then some grounding is required to eliminate this static.

To reduce this type of issue, then a separator can be added to the folded film or static strings and eliminators if they were not pre-installed.

Another method of eliminating static is to use sand paper with a light grit to lightly scrub shiny surfaces.

Only the surfaces that the film drag surfaces (where the shrink film glides over) and any other static-causing spot are to be roughed up.

Common Shrink Wrap Problems

Some common problems displayed by shrink wraps include:

Shrink Film Tears

Usually caused by thickness or type of shrink film used and this heat shrink problem is fixed by changing the type of film used.

Dog Ears

These triangular projections on the corners are caused by the filming not shrinking sufficiently and is avoided by applying more heat.

Fish Eyes

They are oval or round patterns on the film surface due to poor air velocity or lack of heat and is avoided by proper maintenance of heating element.

Burn Holes

They are as a result of too much heat applied on the film and can be avoided by exposing the film to the correct temperature when sealing.
