When you put all this time into designing and creating your custom labels, the last thing you want is for them to not stick to your product or start curling up while still in storage.
But worry not. In this post, we will cover why certain labels won't stick and how you can make sure that your labels look perfect and stick.
Why won't my labels stick?
There are plenty of reasons why your permanent labels are not performing the way you want them to. Have a look at the most common issues below.
Textured or unclean surfaces
Labels do not stick to textured or dirty surfaces as well as they do to flat surfaces. This is because the adhesive on the back of the labels is not able to grip onto the surface as well, which can cause them to peel or curl up over time. In order to prevent this from happening, it is important to make sure that you apply your labels to flat surfaces that are free of any dirt or dust. Simply use an alcohol-based cleaner to wipe the area before applying your labels.
Wetness from water or an oil film can cause adhesive to either not bond with the surface or lose its grip over time, which can lead to your label curling or peeling. In order to prevent this, make sure that the surface is completely dry before applying the label. If you are worried about your label being exposed to water, choose the right waterproof label material.
Some materials are more prone to peeling or curling under certain conditions, such as wetness or contact with oils. If you are looking for a label material that can resist water and oils, printed plastic or vinyl labels with a medium-strength adhesive are a good option. High-quality paper labels can stick just as well, but they are more likely to peel when exposed to moisture.
Of course, the adhesive used during label printing is key to making sure they stick. Most labels come with a medium-strength permanent adhesive, which makes them perfect for applying them to hundreds of surfaces. There are also low-tack and high-tack options. However, low-tack mostly works for short-term applications, whereas high-tack can potentially damage the surface. If you are unsure, get self-adhesive samples before you place your order.
What is a permanent adhesive?
A permanent adhesive describes the durability of the glue. Other than removable adhesives, a strong permanent adhesive binds two components (e.g. label and surface) together permanently. Now, this does not mean that you cannot remove the label, but it ensures that your label sticks. Permanent adhesive labels are the ideal all-rounders and stick to plenty of surfaces, like:
- Galvanized or powder-coated metal
- Plastic bottles or tubs (ABS, PET/PETE/polyester plastics)
Does heat make labels stick better?
We use a pressure-sensitive adhesive on our labels. That means that the adhesive is activated once you press it onto your surface; heat is not needed. However, the heat from a hairdryer can help mould your adhesive, especially when you are applying your labels to a curved surface. Do not worry about damaging your labels. All our labels are made to withstand heat of 80 degrees Celsius.
How do I stop my labels from curling
Curling means that the edges or corners of your labels are starting to lift from the surface and have started curling towards the centre. Once this happens, it seems almost impossible to press them back down and create a smooth look. So let's have a look at how you can prevent this.
Your labels will arrive on flat A4 sticker sheets. This is perfect for keeping your labels straight. Lay them down flat and store them in a cool and dry place. Humid environments can cause the material to curl.
If this does happen, you can counteract it by folding your sheets the other way and putting a heavy book or other flat objects onto them.
