How Does Shrinkwrap Machinery Work?

Shrinkwrap machines work by encasing a free sleeve or envelope of loose shrink film around a product. Heat is then applied to shrink the free sleeve or envelope 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. If the film is properly applied by a shrinkwrap machine then the packaging will conform more tightly to the product shape and result in a thin amount of plastic over the perimeter of your goods.

Shrink wrapping can either be done by a heat gun or through specialist packaging machinery. 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 Type Of Shrinkwrap Machine Do You Need?

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. If you would like to discuss individual requirements then Kempner can help you to understand which packaging machine and shrinkwrap film options may be best suited to your needs.

How a shrink wrapping machine operates depends on the type of shrink wrapping machine involved. The three significant kinds of shrink wrapping machines are the chamber sealer, the L-sealer, and a side sealer.

A chamber sealer puts the product with the shrink wrap film through a compartment, or chamber, where the shrink wrap is ready to be wrapped around the product. The compartment is heated, so the shrink wrap then compresses, surrounding the product and forming a protective layer. The time this process takes depends on the thickness of the plastic.

An L-Sealer is specifically designed for larger volumes of shrink wrapping. If you are using one of our automatic L-sealers, once plugged in and set up, you feed your product through the machine.

The L-sealer has two sealing bars, which make a backwards L (hence the name). The shrink film folds along these bars to create a pocket through the crease of the fold for your products to enter. Once your product is placed in that crease, the other three sides of the shrink film need to be sealed. The shrink wrapper detects when a product is entirely in the machine to know when to wrap your items with shrink film before pushing it further down the production line. Afterwards, typically a shrink tunnel in the production line takes the unheated shrink wrap that has been attached to each item and heats up the wrap until it tightly fits around each product.

A side sealer is the quickest and most versatile way of packaging large volumes of products. They wrap products in a continuous tube of film, sealing one side of the package then separating individual units downstream through a cross seal. Side sealers usually come in one of two configurations: two belts or three belts. A two belt sealer is more compact (only slightly bigger than an L-sealer) and eliminates one of the indeed belts to make the end seal before the side seal. They are best when you need to wrap longer products but cannot afford to expand production line lengths. Three belt sealers are slightly larger than two belt sealers and have the added advantage of precisely spacing the products before entering the wrapping area.

Semi-Automatic Shrink Wrap Machine

Our semi-Automatic shrink wrapping machines add a degree of automation to the shrink wrap process, to aid both the seal function and permit the automatic transfer of packs to the shrink tunnel. With these shrink wrap machines, pack speeds of up to 10 packs per minute are normally achievable.

Fully Automatic Shrink Wrap Machine

A fully automatic packaging shrink wrap machine begins with an output rate of 25-30 packs per minute and moves up to and beyond 100 packs per minute. This removes direct operator involvement whilst maintaining enough flexibility to be customised for most shrink pack profiles.

We would request any potential user of our wrapping machinery to seek our specific guidance, so that we can ensure that the most appropriate selection of equipment and shrink wrap film is made.

Why Use A Shrink Wrap Machine?

If you decide to use shrink wrap in your business, there are many reasons to invest in a shrinkwrap machine. For one, automatic shrinkwrapping machinery dramatically speeds up production lines. By substituting in manual wrapping for an automated machine, you do not need to complete the tedious, time-consuming tasks of packaging products in shrink film, which gives you more time to achieve more meaningful work. You also save on film costs: automatic shrink wrapping machinery is much more efficient with the amount of film it uses on each product than someone could hope to be by hand, which means shrink wrapping machinery can save you even more money in the long run.

Shrinkwrap machinery also helps significantly with inventory control. On the one hand, when you use the right shrink wrapping machine, your goods will be securely wrapped to prevent damage from dirt, dust, and moisture. This can give you added peace of mind that your stock is ready for shipping. On the other hand, shrink wrapping lets you bring consistency to how much shrink wrap you use per product, allowing you to more accurately know how much material you will need at any one time and reduce your storage requirements.
