Everything You Always Wanted to Know About Labelling Machines (but were afraid to ask)

“When it comes to [automatic labelling], there are some mysteries that should remain unexplored. And with my luck, they always will be.”

So said Woody Allen (sort of) but we are here to unravel those mysteries for you!

Now nobody could argue that automatic labelling is sexy - but it is important. ALL brands rely on good labelling to ensure their product is instantly recognisable and perhaps even more importantly, that it conveys regulatory information such as ingredients, instructions or safety information. All consumer goods (FMCG at least) carry barcodes and many companies now require labels to carry tracking information too.

If you’re looking to produce goods at scale, there’s clearly no way your labelling needs can be met by a manual process. So what are your options?

What is a labelling machine?

Labelling machines are used in packing lines to apply labels onto all types of packaging including bottles, jars, phials, tubes, pouches and cartons. Machines increase efficiency without increasing labour costs, plus improve the speed of applying labels and, are much more accurate.

You can also combine a labelling machine with a filling and/or capping machine to complete your production line for a fully automated system.

Are labelling machines all the same?

Definitely not! There is such a huge range of machines - many made for a very specific purpose - that it can he hard to know what to choose. Ultimately it depends on your needs and talking to an expert can really help to narrow down the choices. These are the broad types to consider:

• Manual label machines: machines operated by hand, perfect for smaller production lines. Although manual, they will still improve accuracy and speed.

• Semi-automatic label machines: great for speeding up labelling, semi-automatic labelling machines are usually operated by a hand or foot switch. Good for growing production lines still at the smaller end of the scale.

• Automatic label machines: mainly used in high capacity production, these machines automatically adjust and will bring you the highest application speeds. 

• In-line label machine: automated for high volume projects that require precision and consistency, these machines are easily integrated into existing production and packaging lines.

• Rotary label machine: the best choice for high-speed labelling, rotary labelling machines are large and expensive but offer great efficiency for large scale production lines.

• Print-and-apply label machines: these machines are all-in-one solutions for printing labels and applying them to your packaging in one process. They really speed up production.

Why do I need labelling at all?

As we already said, branding and identification of products is key to grab the attention of customers and inform them they are buying the brand they want, so labelling is used to encourage consumers to make a purchase. It is also its own advert: picture a shelf full of Coca-Cola, or Marmite if you prefer…

In food production you will have to include expiry dates, ingredients and nutritional information. Pharmaceuticals and cosmetics have very stringent requirements for labelling.

You might also need to include instructions and, as we mentioned, there’s barcodes and tracking information also needed.

Okay so what kind of label do I need?

Labelling machines can create and apply labels in a number of ways, including:

• Top and base labelling: often used in fresh and pre-packed food and cosmetics, two separate labels are applied to the top and bottom of the product.

• Front and back labelling: two separate labels are applied to the front and rear of a the product.

• Wraparound labelling: makes the best use of the surface area of your product by applying a single label around the circumference. Works best on cylindrical packaging.

• C-wrap or clamshell labelling: applies a single label from the top of the pack and down the sides, sealing the product. Often used in cosmetics and pharmaceuticals.

• Watch strap labelling: like a clamshell label with the addition that it tucks underneath the package as well.

• Tamper-proof labelling: one or two labels across the product seal for safety, often used in medicine or alcohol.

There are also a number of different types of label, including: 

• Security labels: can include RFID and smart labels, holographic labels, tamper evidence, counterfeit deterrence and theft deterrence.

• Tamper-proof labels: provide protection against tampering to ensure the product reaches the consumer unopened. Sleeving equipment can apply a sleeve of heat-moulded plastic to the neck or body of the container.

• Removable labels: made with custom adhesive so that customers can remove the label after purchase. Some labels are in two parts, with the top layer removable so that more information can be read underneath - often used in pharmaceuticals.

How do labelling machines work?

A labelling machine consists of a number of components and parts that work together to print and apply the label onto your product with little manual effort. Sometimes these are fully integrated, bespoke set-ups and sometimes you’ll begin with a simple labeller and then add more machines later on - as your production grows.

First, the product is fed into the machine via a conveyor belt or roller, which moves the product to allow the label to be attached. Once the machine has labelled the containers, they are then ejected. Sometimes you might need additional machines such as a bottle unscrambler - this ensures bottles are the right way up and positioned ready for labelling.

You might also use a print and apply system.

However, all machines still require an operator to set up the parameters and monitor to ensure they run smoothly. Many machines will alert operators if there is an error or fault.

How do I begin the process of commissioning a labelling machine?

The best way is to start by talking to an expert who can advise you on the type of machine you’ll need. Don’t be put off by assuming they will automatically sell you one of their own set-ups or that they will try to get you to spend more. A good supplier will provide you with free advice that is suited to your needs and won’t be concerned if you don’t go ahead and purchase. Take your time and do your research.

We do also have a free tool that might help. It’s our automated product configurator - you simply input your needs and it will advise you of the product or products that we think are best suited. You are then free to research those products and decide which to go for, or get further personal advice from us.
