Shrink wrap machines are an important aspect of many businesses, especially when large amounts of merchandise are involved. Have you wondered if a shrink wrap machine would be right for your company, and if so, which kind of machine you would need? There's no reason to look any further because we've included a comprehensive list of shrink wrap machine types to help you better understand the types of machines available and their methods of operation!
Shrink wrap is a polymer plastic film used to protect items. Using a heat source to shrink the wrap to the dimensions of the product it is covering, shrink wrap is applied to fit a product securely. Either a shrink wrap machine or a hand-held heat gun is used as the heat source.
As the name implies, 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.
This specific variety of shrink wrap 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.
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.
Compared to an L-sealer, a sealer with two belts is a little larger and removes one of the side sealer belts to create the last seal just before the side seal. When you need to wrap larger things but don't have the time to extend the length of the production line, this type is the most effective.
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 provide a quality shrink packaging solution in a compact footprint. Systems are available as automatic combo systems or semi-automatic combo systems. Combo systems are available in greatly equipped heavy duty combos, or you can find more compact sizes and customize your options with a standard duty combo system. 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. Shrink wrap machines are used to provide a transparent, tightly wrapped package. Practical and cost effective, shrink packaging is great for packaging boxes, cartons, multi-packs, & beverage cans.
With the seemingly endless amount of shrink wrap products and machines available on the market, it can be a daunting task to attempt to figure out which products are the best fit for your company. By contacting a reputable shrink wrapping company regarding your needs and questions, you can find exactly the methods and products that are right for you!

What is a Shrink Wrap Machine and How Does it Work?
Shrink wrap machines are an essential part of any business selling large amounts of goods
Shrink wrap machines are an essential part of any business selling large amounts of goods. If you are interested in incorporating a shrink wrap machine into your business to improve the efficiency of your current packaging solution, read on below for information about exactly what a shrink wrapping machine is and how they work.
What is Shrink Wrapping?
Shrink wrapping is a procedure where an item is wrapped in a free sleeve or envelope of loose polyolefin shrink film, and heat shrinks the wrap and firmly around the product. The result is a tight, crystal clear wrap around your item.
Shrink wrapping is typically stronger than alternative wrapping solutions like overwraps or stretch wraps. They also conform more tightly to the product shape, usually simply producing a thin amount of plastic over the perimeter of your goods.
What is Shrink Wrapping Machinery?
Shrink wrapping can either be done by a heat gun or through dedicated shrink wrapping machinery. Heat gun shrink wrapping is most often done by individuals who have a very small number of products to shrink wrap each week. For businesses, a shrink wrap machine is vital to efficiently and quickly wrap as many products as they can in as short an amount of time as possible.
What kind of shrink wrapping machinery you need for your business will depend upon understanding your current wrapping process and what you want to achieve. You will need to think about the motivation behind the wrap, how quick is the generation procedure, what range of sizes are required and how fast a changeover is required. Whatever the need, there will be a shrink wrapping machine created to meet the application.
How Does Shrink Wrapping Work?
Many of us don’t really think about how a shrink wrap machine works or how the plastic ends up wrapped tightly around the product. However, it is about controlling and manipulating polymer particles; polymers are long atoms found in plastic, where they are generally twisted and arbitrary, and therefore unsuitable to act as a wrap. When they are made into a plastic film for shrink wrapping, the molecules are extended straight into a thin layer, perfect for wrapping around another product.
This film is then positioned around whatever needs to be wrapped. Once the warmth is connected to the film, it shrinks, because the heat makes the polymers come back to their regular tangled state. How much a polymer shrinks depends on what kind of polymer it is: PVC shrink wrap film can shrink as much as 50 percent of its unique size, while polyolefin shrink wrap film shrinks slightly less, despite offering stronger seals than PVC.
The Benefits of Shrink Wrapping
Shrink wrapping makes products more sealed and keeps out dampness and light introduction as well as protecting the product during transit. Shrink wrapping, for instance, is excellent for CDs as you can observe the cover, as well as food products and pharmaceuticals. Shrink wrap is also known for being a low-cost packaging solution, with an outlay for the packaging machine, polyolefin shrink wrap film is very economically friendly. Polyolefin shrink wrap film may seem thin – it is, in fact, the thinnest on the market – but this doesn’t compromise its strength.
Having been tried and tested for many years, these are just some of the reasons that shrink wrap is one of the leading packaging solutions in the world. For more information, read our article on the benefits of shrink wrap and how it can help your business.
