Many different businesses have a shrink wrap on their products, and the shrink-wrap market is enormous. There are many different shrink wrap machines and technologies available since shrink wrapping has a variety of requirements.
Do you wish to grow your company while increasing the effectiveness of its entire output? Many industries depend heavily on an industrial shrink wrap system, especially when the exchange of large quantities of goods is at stake. So, there’s no need to look any further because we’ve included a comprehensive list of all the data you’ll need to enhance your company strategies below.
Understanding Shrink Wrap System
A polymer plastic film called shrink wrap is used to protect items. Using a heat source to shrink the wrap to the specific dimensions of the product, shrink wrap is applied to fit a product snugly. A shrink tunnel or a hand-held heat gun is used as the heat source.
Shrink wrap is frequently used for the following purposes:
- Box security
- combining drinks and canned goods
- Adding to the product’s protection
- Tamper-proof sealing
- huge pallet loading with security
- Packaging combinations
- packaging and sampling used for promotion
A thin film of polyolefin shrink wrap is coated around the item after it is placed in the shrink-wrapping machine, which is not a quick and straightforward process. The film is then tightly shrunk around the object using heat.
In the end, the object is covered in a transparent, sparkling layer. Because it is stronger and safer than stretch wraps or overwraps, it is typically preferred. Additionally, it forms a thin, translucent layer of plastic on top and more exactly fits the object’s shape.
Types Of Shrink Wrap Systems
Shrink wrap equipment is ideal for quick wrapping of products. A hand-held heat gun isn’t cut for shrink-wrapping things on a wider scale. The following are a few examples of the numerous types:
Heat Sealers Shrink Wrap
Shrink wrap sealers come in various sizes and shapes, depending on the needs of the production. Most shrink wrap operations, regardless of size or scale, use a heat sealer to close the open ends of the shrink wrap material. I-Bar sealers and L-Bar sealers are the two most used heat sealers for smaller enterprises.
An I-Bar Sealer is known as a shrink wrapper with a singular sealing bar that closes the wrap to enclose the product. Because they don’t excel at high speeds, I-Bar machines are typically found in activities with a lesser output.
Shrink wrap machines with L-bar sealers are more efficient than I-Bar Sealers since they work faster. The L-Bar sealer gets its name because it contains two sealing bars in the shape of a backward L.
Shrink Wrap Machine
Those who do not have heavy materials on their hands and need to manage a little load every week use the gun. It can be done using either a heat gun or a shrink-wrapping machine. However, a pistol would be useless because businesses must deal with bulkier products in huge quantities.
As a result, a shrink-wrapping machine would be ideal for quickly wrapping large items. The type of shrink-wrapping equipment you’ll need depends entirely on your present-wrapping technique and the tasks you intend to complete.
You’ll need to consider all potential issues, such as how fast the generating process works, what size array is required, how quickly a changeover is possible, and so on. A shrink-wrapping machine will be easily available if you specify your needs.
Functioning Of a Shrink Wrap System
Most of us will pay little attention to the industrial shrink wrap machine’s overall technique and operation. The key is manipulating and changing particular polymers; polymers are long chains of atoms in plastic. They are usually found in a deformed state, making it difficult to wrap them.
When polymers are produced into a wrap-able plastic film, their molecules are stretched into a fine layer, making them ideal for wrapping around various objects. The film above is wrapped around the thing to be wrapped. When the high temperature is applied to the film, it immediately shrinks. Warmth causes the polymers to revert to their original deformed shape.
Why is this the case?
On the other hand, the size of a polymer shrinks entirely depending on its kind. For example, PVC shrink wrap film can shrink up to 50%, whereas polyolefin shrink wrap film shrinks a little less, despite being a harder sealing alternative than PVC.
Advantages Of Industrial Shrink Wrap System
It is chosen over other wrapping methods because it maintains the safety of the products, protects them from moisture and strong light, and keeps them secure throughout transportation. Shrink wrapping is ideal for wrapping CDs, which may be seen through the cover and food and drugs. It is also well-known for its cost-effective packaging.
The polyolefin film for shrink-wrap may appear thin at first glance, and while it is the thinnest film on the market, its strength is unmatched. These are just a handful of the numerous reasons why shrink wrap film is the greatest alternative to any other type of packaging.
Working Mechanism of Shrink Wrap System
The type of shrink-wrapping machine determines how it operates. The three most prevalent shrink-wrapping machines are the chamber-sealer, L-sealer, and side sealer.
As the name implies, the chamber sealer passes the things through a chamber or compartment where the shrink wrap film is prepared to be wrapped around the product. The shrink-wrap is squeezed and creates a tight coating around the object in this chamber because it is heated enough. The width of the plastic determines the length of time it takes to complete this process.
When an item is entirely inside the machine, the L-sealer can determine when to coat the things with shrink film. Later, along the manufacturing line, a shrink tunnel grabs the unheated section of the shrink wrap attached to each product and warms it up so it can snugly fit around each item.
Last but not least, this is the quickest and most convenient way to bundle things in large quantities in a short period. The items are wrapped in a nonstop film pipe that covers one side of the item before a crisscross seal separates the different sections downstream. Side sealers are often available in two configurations: two or three belts.
Sealers with three belts are slightly larger than sealers with two belts, and they also have the advantage of creating precise spacing between the products before they enter the wrapping area.
