What Is Heat Shrink Packaging Machine

 

 

Heat shrink packaging machine is machinery that shrinks any material to be wrapped or to call it in simple terms – a shrink wrapper. It is included in a plethora of industries most dominant being the food and beverages industry. However, all segments including pharmaceuticals have majorly started using the heat shrink packaging machines extensively. Shrink wrap is done with the help of a shrink film and shrink machine which albeit looks thin but is ultra-strong as it comprises of a few layers and bonded strongly. Heat shrink packaging machine wraps an item in a free sleeve or a loose polyolefin shrink film and heat is used to shrink the film tightly around. Shrink packing machines are very handy when a bulk of goods needs to be shrink-wrapped.

Benefits of the Heat Shrink Packaging Machine

Some important benefits of the heat shrink packaging machine include:

Heat Shrink Wrap Machine
 

Tight wrapping

The heat shrink packaging machine is able to deliver a tight wrapping and sealing to eventually save on film consumption and on usage of heat energy. Despite this, the open sides of the package are easily unwrapped when the product is opened up for usage.

Controls

Advanced technology has been used in the development of the automatic shrink wrap machines. The machine is operated through a programmable logic control system and the settings are monitored from a touch screen panel that is integrated in the electrical cabinet. With this kind of innovation, the machine becomes a compact unit occupying a small floor area and will easily fit along any production process.

Height

With the different manufacturing systems around the world having different configurations, the automatic and semi-automatic shrink wrap machines and designed with adjustable height levels, that make it easier to connect the in feed and out feed conveyors in the production line.
The auto shrink wrapper support system has also been fitted with roller wheels for easier moving the equipment from one point to another in the production facility. This also allows for a flexible production layout.
The heated air in the shrink tunnel is directed by means of adjustable flaps that enable the achievement of even and optimized shrinking process. These heat directing flaps are easily operated from outside.

 
 
Types of Heat Shrink Packaging Machines
 
 
Chamber sealer

The chamber sealer passes the items through a chamber or compartment where a film of shrink wrap is used to wrap the item in. The shrink-wrap is compressed and forms a solid covering over the object in this chamber as it is heated enough to do so. Depending on the width of the plastic, the time for this operation varies.

 
L-sealer

This specific variety of heat shrink packaging machine was developed to accommodate larger sizes of shrink-wrapping material. If you have an automatic L-sealer handy, set it up, plug it in, and place the thing you want to seal inside. Two sealing bars on this device have the shape of a backward "L." in order to form a pouch-like aperture via the crinkle of the folds and allow your goods to pass through, shrink film bends down the two bars.
Once your object has been securely positioned inside the crease, the shrink film has three other sides that need to be securely sealed. When an object is fully loaded into the machine, the l-sealer can identify when to cover it with shrink film. Later, a shrink tunnel in the manufacturing line gets a hold of the unheated part of the shrink wrap attached to each product and warms the wrap so that it can firmly and securely fit around each item.

 
Side sealer

This is the quickest and most practical way to bundle a large number of products in a short period of time. The goods are wrapped in a continuous pipe of film, with each unit being divided downstream by a crisscross seal after being covered on one side. There are typically two configurations for the side sealers: Two or three belts.
The sealers with three belts, on the other hand, are slightly larger than those with two belts and have the advantage of precisely spacing the items before they enter the section where they are to be wrapped.

 
Combo shrink systems

Combo shrink systems provide a quality shrink packaging solution in a compact footprint. Systems are available as automatic combo systems or semi-automatic combo systems. L-bar sealers and heat shrink tunnels are combined in one industrial shrink wrapping machine to provide tightly wrapped packaging solutions. First, sealed in a bag using the l-bar sealer, the package then moves to the shrink tunnel where the film is heated and shrinks around the package. Heat shrink packaging machines are used to provide a transparent, tightly wrapped package.

 

 

The Heat Shrink Packaging Machine Process

 

The heat shrink packaging machine process consists of 3 steps:

 
01
 

Product grouping

The products are arranged into a group (e.G. 3×2 bottles to form a 6-pack), in slower machines the product is fed single lane and grouping is done inside machine by successive strokes of pneumatic or electric pusher (or lifter.) in faster machines the product is introduced in multilane or pre-collated outside of machine. While high speed machines use continuous motion grouping

 
02
 

Bundle forming

A sheet of shrink film is wrapped around the products forming a bundle. There are currently two main ways for wrapping the product:
● Using two rolls with hot knife cutting and sealing
● Using single roll with cold knife cutting and overlap sealing in tunnel

 
03
 

Heat shrinking

The bundle passes through a heated zone of the shrink tunnel, where re-circulated hot air causes the film to shrink and conform the the shape of enclosed products. Once outside, the pack is cooled by forced air to tighten the film forming semi rigid pack ready for stacking on pallet or further downstream packaging.

Top Tips for Maintaining Your Heat Shrink Packaging Machine

 

When you purchase capital equipment like wrapping machinery, you not only want it to deliver premium performance and results, you want it to stand the test of time. To protect your investment whilst ensuring you get the most from your machinery throughout it's lifetime, we recommend following these easy steps to maintain it:


Regularly monitor and replace the parts of the machine that experience wear and tear. For most sealers this means the base tape, the teflon tape and the sealing wire. For shrink tunnels this is usually the lubricant that keeps the chains running smoothly. For your convenience, we supply dedicated spare parts lists with every machine that categorises parts according to the frequency they will need to be changed.


Run high-quality films. Purchasing cheaper films is always a false economy when it comes to getting the best from your shrink wrapping equipment (and pack quality). Using high-end films reduces costs in production through reduced temperatures in the tunnel and faster seal times, translating into greater production rates. However high-end films also reduce the build-up of film caught along the sealing jaw/blade which will not only produce poor seals on your packs but will affect the lifespan of the part. Furthermore, high-quality films usually take advantage of ultra-thin technology. This means the gauge is reduced compared to conventional films, without any sacrifice to their properties. The thinner micron films can be run at lower temperatures and therefore significantly reduce the output pressure on the sealers and shrink tunnels over time, whilst also removing the potential for damage caused by scorching or blistering.


Keep it clean! Dust and debris can impair the performance of your machine and also the finish and quality of your packs. If you are wrapping food or pharmaceutical items, maintaining a hygienic packaging line is even more critical, for obvious reasons. A regular wipe down of the equipment with a non-abrasive, clean and dry cloth should suffice. In particular, the sealing jaws on our machinery should be checked at the end of every shift to ensure no debris is caught in them. We also recommend using a dust cover when your machine is idle as a hassle-free solution to keeping it spotless.


Keep it dry! Moisture can be damaging to mild steel machinery as it can cause rusting and corrosion. If you are wrapping liquids like chemicals or drinks, you would benefit considerably from upgrading to a stainless steel system, which can be easily washed down, for an increased lifespan.


Implement a servicing schedule. Customers who run an intensive 24-hour wrapping operation will need more regular preventative maintenance than those who power up their equipment only seasonally or have low volumes. They will compile a personalised schedule with an arrangement to contact you prior to a service due date.

FAQ
 
 

Q: What is a shrink packing machine used for?

A: The shrink wrapping machine is widely used in many packaging fields including foods, beverages, pharmaceuticals and chemical products. The equipment can be used for multiple packaging of products either in loose form, prepacked in cartons or packaged in trays.

Q: What is heat shrink packaging machine?

A: They provide both sealing and heat shrinking in a single motion and so quickly! Heat shrink packaging machines dispense a film over a product, which is heated, and this forms a tighter wrap around the product, creating a secure covering. These are a much faster alternative to other desk top systems.

Q: How does a heat shrink packaging machine work?

A: The bundle passes through a heated zone of the shrink tunnel, where re-circulated hot air causes the film to shrink and conform the the shape of enclosed products. Once outside, the pack is cooled by forced air to tighten the film forming semi rigid pack ready for stacking on pallet or further downstream packaging.

Q: What are the features of shrink wrap?

A: Shrink wrap is typically a clear plastic or polymer-based film that shrinks when heated to conform to the shape of the object it is wrapped around. Shrink wrap can form a very tight, tamper-evident seal to protect the products from insects or other pests, moisture, dust or other contaminants, and discourage theft.

Q: What temperature should heat shrink packaging machine be?

A: The shrink-wrapping process requires heat to shrink the packaging around the product, and this is the part of the process that can cause damage. The average temperature achieved by a PVC shrink wrap will be between 120ºc to 130ºc, whilst a standard polyolefin shrink wrap machine requires a 150ºc to 175ºc setting.

Q: What types of shrink films can be used with a heat shrink packaging machine?

A: Various types of shrink films can be used with a heat shrink packaging machine including PVC, polyolefin, and polyethylene films.

Q: What is the problem with shrink wrapping?

A: Ballooning. Ballooning occurs when there is exposure to excessive air after sealing. This problem is common with items that have not been sealed before using shrink wrap. If the material is sealed before the film begins to shrink, the trapped air has nowhere to escape.

Q: Is it easy for heat shrink packaging machines to shrink packaging?

A: Shrink wrapping is an easy process that only requires two things—the right kind of plastic wrap and heat. Shrink wrap is a plastic film that you can wrap around any object, no matter what size or shape. Heat is then applied to the surface, which causes the plastic to shrink.

Q: What are the different types of heat shrink packaging machines?

A: There are two main types of heat shrink packaging machines: I-bar sealers and L-bar sealers. I-bar shrink wrap machines are often used for low-to-mid volume applications. These shrink wrap machines have a long bar to make single cuts in PVC or polyolefin film.

Q: Why is my heat shrink packaging machine not shrinking?

A: First, allow more film around the package, then adjust the tunnel parameters by increasing the conveyor speed, turning down the temperature and reducing the air flow. If this does not work, chances are your film's shrink force is too aggressive.

Q: What temperature should heat shrink packaging machine be?

A: The heat shrink packaging machine process requires heat to shrink the packaging around the product, and this is the part of the process that can cause damage. The average temperature achieved by a PVC shrink wrap will be between 120ºc to 130ºc, whilst a standard polyolefin shrink wrap machine requires a 150ºc to 175ºc setting.

Q: What is the function of heat shrink packaging machine?

A: A heat shrink packaging machine is a type of thermal machine used in the packaging industry. This machine wraps a PVC or polyolefin film around the products and then increases the temperature of this film. This temperature increase allows the film to tightly wrap around the product, thus packaging the product.

Q: What industries can benefit from heat shrink packaging machines?

A: Food and beverage: Snack food production factories, such as those producing chips, cookies, and candy, rely on heat shrink packaging machines to maintain product freshness and extend shelf life.
