Although it’s not something consumers are likely to ever see, a label liner plays an important role in the application of a pressure sensitive label. Since these liners can affect the performance of pressure sensitive labels but are often overlooked, we want to provide all the information you need to choose the right option for your specific needs.
The main purpose of a label liner is to carry a label to the applicator and then ensure that they’re easily released onto the product that’s being labeled. While the right type of liner can ensure this process runs as smoothly as possible, the wrong one can cause the process to go very slowly. Not only will an inefficient process result in lost time, but it will also cause material to be wasted.
As with considerations like finishes, adhesives, inks and label materials, there’s not really a label liner that’s “best” in traditional sense. Instead, what’s best depends on how a label liner is being used with a pressure sensitive label. By understanding the different options that are available, you can then take that knowledge and use it to select the right liner.
There are five different criteria used to measure the performance of a label liner. Those criteria are die-cutting, cost, lay flat, strength and dust. Criteria like die-cutting and dust are going to be more relevant to certain application types than they are to others. In terms of the different types of label liners that can be used for pressure sensitive labels, there are four main options that are most common.
The first is semi-calendered Kraft (SCK). While SCK has a low cost and is good for die-cutting, its main weakness is lay flat. If lay flat is the most important consideration, lay flat liners (LF) are a great choice that only cost slightly more than SCK. Poly-coated Kraft (PK) and polyester film Liners (PET) are the other two main liner types. PK is quite strong and has a low dust particulate. PET offers the lowest dust level. They’re excellent for speed die-cutting and stripping but fall short with sheeting.
We covered a lot of information above. So if you have a better understanding of label liners but still aren’t exactly sure which type is going to work best for your labels, don’t worry.
