Craftsmanship is essential

A label looks a very simple product; a piece of paper or plastic with some printing on it. But it takes much more to produce a good label. A label must be applied at high speed, with no disruptions to the labelling lines. What makes a label a good label that can be applied at any speed and in any conditions?

Choose the right materials

First of all, the choice of the right substrate is very important. This is a combination of the type of labelling machine, the type of glue and mainly the climate conditions in the factory during labelling. Paper is a natural product and reacts to its surroundings. The specifications of the substrate must meet the requirements of the humidity of the production site. A well-chosen substrate is essential for good process ability.

Type of varnish or lacquer

Secondly is the choice of lacquer or varnish. Not only has varnish a decorative function; glossy or matt (or combination of both) appearance, but it also has a protective function. Packaging without a reversed panel can get damaged during transportation because of the friction of the labels. By using varnish you have less chance the labels can get damaged.

The choice whether or not to use varnish has also an influence on the surface properties of the label, such as water repellency and/or slip factor. A proper slip factor is essential for good and fast labelling. If the labels are too stiff, multiple labels can be simultaneously picked from the magazine instead of only one. If the labels too slippery they can fall out of the magazine. A good balance must be achieved.

Consistency of colour

Of course the colour of the labels must be consistent. Not only for the first print runs but also for the the 100.000th. The products from different production runs must be identical if they stand next to each other on the shelves. We print our labels according the guidelines of ISO 12647 with CYMK and PMS or special colours. By doing so, we can guarantee the consistent quality at all times.

Consistency in size

The final important factor for good runnability of labels is a consistent size. We deliver the labels in cut & stack, die-cut & stack or in reel formats. Our labels are cut with high precision and always with a sharp knife and our equipment is set up to a hundredth of a millimetre. We have invested in high-quality cutting and die-cutting tools to achieve this. These investments pay off, because our labels are always dimensionally stable, without frayed edges and edge welding. All this contributes to optimal runnability of your labels.

Do you want to know how you can improve the runnability on your production line? We are happy to advise and assist you with this. Please contact one of our experts.

Royal Sens has very good knowledge of the labeling process, therefore it is able to deliver high-quality labels and customers good advice on possible improvements. In addition, the technical knowledge available to meet with us to good solutions for each customer.
