In the world of packaging, the term shrink wrap is something that you would always come across with. It is one of the most cost effective and efficient method of storing and transporting products easily. The film used for shrink wrapping is typically made of polyolefin or PVC.
The process of shrink wrapping is the same regardless of the size of the product or item to be wrapped. First, you measure the shrink wrap film to fit the item. Then, you spread the film over the product. Apply heat using a shrink wrap film unto the film surface. The film will shrink and will stick to the product, ensuring a secure packaging for your products.
You can easily do it yourself for wrapping two or three items at home. Just follow the same procedure of shrink wrap packaging. You can use a hair dryer or blower and buy the film from a nearby shop. However, if you are going to wrap more items, it is best that you invest in a good shrink wrapping machine.
Shrink Wrap Machines
In the past, shrink wrap machines are only found in commercial warehouses or industrial factories. The old version of this machine is bulky and it would usually require many people to operate it.

I-bar shrink wrap sealers
The I-bar shrink wrapping machine is most suitable for low to medium volume of shrink wrapping. This type of wrapping equipment uses a single bar for sealing. You take down the bar in order for you to cut down the part of the film that is needed. Heat gun is used to shrink the film and make it stick to the item.
L-bar shrink wrap sealers
The L-bar shrink wrap sealers, on the other hand, is best suitable for middle to high volume of shrink wrapping. These machines are commonly used in large businesses. As the name suggests, this type of wrapping machine utilizes a sealer bar that resembles the letter L shape that can easily cut the film, in just one pass. Heat gun or heat tunnel is used to shrink the film onto the item. The process of shrinking is faster when using a heat tunnel as compared to using the heat gun.
