Our new tesa ® 4200 ensures reliable and efficient splicing of high slip materials, especially for the release liner industry.
Simply put, release liners can be defined as coated papers or films carrying sticky materials. But usually, nothing is as simple as it seems. An adhesive’s usual purpose is "to stick", but at the same time it should easily be released from the liner material used as an adhesive protection layer. And this requires perfect alignment of parameters such as base material, silicone technology, or coating thickness.
Nowadays, release liners can be found in a vast variety of industries, for example in medical, label, graphics, composites, chemical, electronics, or hygiene sectors; application areas reaching from drinking bottles to medical plasters to holding mobile phones together. Of course, release liners also play an especially important role when producing self-adhesive tapes which makes the application and a well-performing splicing product interesting to us in more than one way.
Despite of market challenges such as scarcity of raw materials or price pressure, the release liner industry faces growth opportunities across the world. Being confronted with the increasing trend towards sustainability, an important development is the rising use of synthetic, film based materials consisting of polypropylene, polyester and polyethylene instead of paper. Those very thin liners do not only involve significantly lower waste and can be produced more efficiently, but they also simplify transportation and storage. At the same time however, changes in materials can be challenging when it comes to secure splicing processes.
With our new tesa ® 4200, we support splicing processes of state-of-the-art release liner materials. The product is a thin, double-sided tape for flying splice, flying core starting as well as static splice applications of siliconized materials. Its major value of very strong adhesion to silicone surfaces leads to a secure splice performance and makes cost-intensive production downtimes a thing of the past. The tape's thin polyester backing ensures excellent conformability and its red color facilitates optical detection to easily remove spliced areas later during production. Another main feature is the tape’s chemical and high temperature resistance which allows its use in a wide variety of applications. Altogether, these features ensure reliable splicing of siliconized materials and increase process efficiency in a substantial manner.

Everyone knows that a solution’s highest efficiency cannot be achieved when its implementation is complicated or unclear. With the development of tesa ® 4200, we did not only focus on achieving maximum product performance but also on facilitating the user-friendliest application.
Within the flying splice application, the top layer of a reel of e.g. release liner material is fixated by using split labels such as tesa ® 54242. After that, tesa ® 4200 comes into play and is applied above the split labels. After liner removal, the reel is ready to be spliced.
For a static splice, the process only differs marginally. First, tesa ® 4200 is applied on a new reel's top layer and then the tape's liner is removed. After that, the end of the previously used reel can be attached to the open adhesive area.
For flying and static core starting, tesa ® 4200 has to be applied onto the core in straight line for static core starting and in a spiral pattern for flying core starting. The application is finished after removing the liner.
In the end, meeting market requirements and providing high performance products requires high quality processes in each phase of the value chain. A step in the direction of highest process efficiency is the implementation of suitable splicing tapes.
