How does shrink wrapping work

For this reason Autopack offer many grouping options and two wrapping systems to match customer requirement. All these forms of packaging, as well as shrink wrapping, can have custom designs printed on the packaging. Most bottles, cans, cartons and boxes are ideal for shrink wrapping. It is also possible to shrink wrap many other sorts of products. Very lightweight or oddly shaped products can be challenging to shrink wrap, either because they are hard to convey and collate during the wrapping process, or because they can not form stable geometrical group which after handling may become loose.

Due to the short exposure time and protection offered by the shrink film itself, very few products are affected by the process. Even foil-wrapped chocolate can be shrink wrapped. It depends on the size and weight of the products. With smaller products, more can be included.

Note that we have vertical stacking options to allow multiple layers of cans and boxes. Although the film shrinks around the products, there will be a round opening in the film on either side of the pack called "bulls eyes". Most Autopack machines are designed to be rapidly adjustable to a wide range of products. Submit an enquiry if you would like to find the best machine to suit your needs. This is because it is relatively strong, inexpensive and can be made with correct shrink ratio for Sleeve Wrapping.

The main advantage of overlap machines is higher throughput, better suited for printed film, they tend to be longer and more expensive. For additional pack strength or ease of handling, a cardboard pad or tray can be introduce under the product before being shrink wrapped.

As a result, a shrink wrapping machine would be perfect to swiftly handle sizeable goods. The type of shrink-wrapping machinery that you require depends entirely upon taking into account your present wrapping procedure and the things you want to accomplish. You will need to think of all the possible problems to tackle, such as how fast the generation process works, what array of sizes are needed and how quickly a changeover may be available, and so on and so forth.

Name your requirements, and a shrink wrapping machine will be readily available. Most of us will not pay much mind to the overall procedure and operation of the industrial shrink wrap machine. The secret lies in altering and manipulating certain polymers; lengthy atoms in plastic are known as polymers.

Here, they are normally found in a distorted manner which makes them difficult to wrap. When the polymers are formed into a film of plastic suitable for wrapping, its molecules are stretched out into a fine layer which makes them excellent for wrapping around different objects.

The said film is placed around the object that has to be wrapped. After the heat is linked to the film, it instantaneously shrinks. Why so? Because the warmth causes the polymers to acquire their initial distorted shape. However, the size that a polymer shrinks is completely dependent on its kind. For instance, the PVC film for shrink wrap is able to shrink for up to fifty percent, whereas the polyolefin film for shrink wrap shrinks a little less, despite being a firmer sealing option than PVC.

It is preferred over other methods of wrapping as it ensures the safety of the products and protects them from any dampness, bright light, and it also keeps the object secure during transportation. Shrink wrapping is perfect for wrapping CDs which can be seen from its covering; it is also perfect for food items and pharmaceuticals.

It is also popular for its economical packaging. At first glance, the polyolefin film for shrink wrap might look quite thin, and while it is the thinnest film available in the market, its strength is no match. These are only a few of the many multiple factors why the shrink wrap film is the best alternative to any other packaging method.

The way a shrink wrapping machine works is dictated by its kind. The chamber-sealer, L-sealer, and side sealer are the three most common types of shrink wrapping machines. The chamber sealer, as the name suggests, puts the items through a chamber or compartment, where the film of shrink wrap is prepared to be packaged around the object.

This chamber is warm enough so that the shrink-wrap is compressed and forms a secure coating over the object. With more attention than ever on the impact of plastic on the environment, many ask can shrink wrap be recycled? So is shrink wrap recyclable: in short it is.

Being made of low density polyethylene — or polythene — means that the answer to is plastic shrink wrap recyclable is yes. Polythene is widely recycled and can be put into the recycling waste and reused.

To recycle it, simply keep it once you have removed it and either put it in the standard recycling or, if you find you have a lot of it, there are companies that will come and collect it and take it away to recycle. They will shred it and melt it down to make polythene beads which may very well end up being used to make new shrink wrap.
