Speaking of flexo printing, that is where tesa® Twinlock, our self-adhesive flexo sleeve, came into play.
At first one set of sleeves was bought, and after one year of testing, 100 sleeves followed.
The main drivers to check out tesa® Twinlock were the reduction of plate mounting tape and the corresponding waste prevention, as well as the idea of improving the efficiency of the mounting process.

Read the full story of tesa® Twinlock @ Walki in our interview:


"As the orders are becoming shorter every year we had to find a mounting technology that will allow us keeping the right efficiency on the printing presses. Printing plates mounting and demounting with tesa® Twinlock is 50 % shorter than traditional tape mounting / demounting as there is no tape in the process. The tesa® Twinlock technology with its effectiveness allows us to be more flexible with our production plan. Today we can react much faster on changing needs of our customers.
tesa® Twinlock sleeves ensure very good plate adhesion during printing, even at high print speeds. In the beginning we were afraid of  possible damages to the sleeves, but we saw that by following some simple rules we can avoid it. We don’t have to treat the sleeves in a very special way."

"When it comes to sustainability, there are three main types of solutions Walki is working with: products that are easy to recycle, compostable and/or biodegradable products, as well as products that are based on renewable resources and thus lowering the CO2 footprint. The right solution or combination of solutions is decided based on customers and end-customers needs. At the same time one needs to have sufficient barrier properties to protect the goods inside the packaging. Many customers are also interested in sustainable printing processes, for example using water-based inks instead of solvents."

"At Walki, we believe in a sustainable and circular tomorrow. Our mission is to accelerate the world’s transition into a zero waste future in packaging and promote the use of energy efficient materials across industries. In addition to developing sustainable solutions for our customers, Walki has initiated an internal continuous improvement program concentrating on reducing waste from its operations and improving production efficiency – more with less. We are also, for example, using environmental friendly water-based inks in all our printing operations and invested in new state of the art printing technology."


"This is becoming more and more important as the average order sizes are getting smaller and the number of change-overs is increasing. Without modern printing machines, optimised processes, and innovative solutions - like tesa® Twinlock - this would lead to increased waste volumes and unfavourable developments when it comes to sustainability."

"With tesa® Twinlock we have exchanged the standard sleeves and tapes, and the cost has returned within 1 year from the purchase. Thanks to reducing the time of mounting process to 50 % we can keep printing press efficiency on a very good level. tesa® Twinlock sleeves work very well on high speeds. We don’t have problems any more with printing plate edge lifting during the printing process."
