The Oxford Dictionary defines packaging as ‘materials used to wrap or protect goods’, but here at Siat, we like to think of it as the science, art, and technology of enclosing or protecting products for distribution, storage, sale, and use. We have been making Siat Packaging Machines for over 30 years now, and our machines are used in various manufacturing plants the world over, but we are aware that not everyone knows what packaging machines are and how they can benefit a business.

To fully understand packaging machines, we really need to understand packaging. Packaging comes in many different forms but tends to fall into two categories – primary packaging and secondary packaging. Primary packaging is best explained as the material that contains the product and is in direct contact with the contents. For example, a plastic bottle containing a soft drink would be classed as primary packaging. Secondary packaging then is the package outside of the primary packaging that may group packages together. So, for example, if we think about the plastic bottle with the soft drink in again, the secondary packaging would be the cardboard tray and shrink wrap used to transport a number of soft drink bottles from the manufacturing plant to the retailer.

There is a wide range of machines out there that deal with both primary and secondary packaging. Here at Siat we are focused on the secondary packaging machines and have a wide range for you to choose from. Each business is different, and the choice of machine for your business will depend on a wide range of factors such as available budget, associated running costs, available floor space, integration, machine technology and payback period.
Packaging machines are usually classed as one of the following types:

Cartoning Machines

Machines that come under the umbrella of cartoning machines are packaging machines that are designed to help with erecting, filling and erecting, filling and closing carton blanks or folded and side seam sealed cartons. As you can probably imagine, cartons are one of the most common types of packaging although you may not realise that although they tend to be either a rectangular or six-sided square shape, there is actually a myriad of different ways they can be filled or closed. For example, some cartons are filled vertically and closed with a fold over ‘lid’ while others are filled and closed via the end flaps.

Other important differences to note include the means of sealing the carton once it has been erected. You could glue it together using adhesive, you could use pre-cut tabs and slots, or you could choose to have the carton pre-coated with a heat sensitive material. Some manufacturers even use window cartons which are cartons that have a pre-cut area behind which transparent film has been fixed to allow the contents to be viewed – like a cake box, for example.

One example of a carton machine is our Siat f144 Automatic Case Erector. This machine can form and seal up to 12 cases per minute – which is a lot faster than doing this task manually.

Closing Machines

Another type of machine commonly used in the packaging process is a closing machine, which is sometimes known as a sealing machine. Sealing machines typically close and seal an individual carton by providing a long continuous horizontal or vertical seal. There are many different types of sealers, from our entry-level Siat SK1 Case Sealer to our Siat SM44 fully automatic case sealing machine.

Pallet Wrapping Machines

Another type of packaging machine that Siat specialises in is the Pallet Wrapping Machine. Machines that deal with Pallet Wrapping and securing a deal with the task of securing goods onto a pallet in such a way that they stay secure and protected during the distribution process. Modern manufacturing techniques mean that most sectors now use pallets for storage and transport of products, and so this a growing sector for us.

Many of the packaging machines that we deal with here at Siat can be integrated into an existing line. For example, a new case sealer machine can be placed within an existing line. However, interfaces between new and old machines should be considered before this is undertaken as well as entrance and exit routes for the equipment. Downtimes of the line and surrounding lines should also be taken into consideration to, as this will have an impact on your bottom line.

Whatever your need from single machines, such as the Siat SK1 as discussed above, to small systems or complete lines containing more than one new packaging machines, whatever your query you should talk to us today. You can contact our experienced team on 01924 483000 or by email at
