The ecopti-box – a revolution in the way facial tissues are packaged
A conventional folding box for the packaging of paper handkerchiefs has always had a specific design shape for the
removal opening. After the perforated area on the lid of the folding box has been separated, a functional layer underneath – usually made of paper, and in the past often even made of PE film – becomes visible.
This layer has the following function: It allows you to reach into the box to grab the top tissue. At the same time, the layer forms a barrier for the next tissue, so that the entire stack of tissues is not pulled out, but only one tissue at a time.
In the production of such a conventional tissue folding box, in addition to the classic processing steps of printing, punching and folding gluing, another step is necessary: gluing in the functional layer described above. Since, in line with the idea of sustainability, this functional layer is again predominantly made of paper (and no longer made of PE film), the question arises as to whether you really need to stick another piece of paper into a box that is already made of paper. Especially since this process requires valuable resources such as paper, electricity and labor.
Current challenges such as climate change, energy crises and a shortage of skilled workers remind us that our resources are not available in unlimited quantities. Therefore, it is more necessary than ever to question what you can do without without functional restrictions.
So why not use the material of the folding box and develop a mechanism that eliminates the need to glue in another piece of paper. But how do you get the properties (flexible engagement and backstop function) that the functional layer of paper fulfills into the already existing, quite stable and thick base material of folding box board?
A special, already known opening variant served as the inspiration, in which the cardboard material is cut (scored) in parallel with a distance of a few millimeters, once from the outside and once from the inside, a little more than half of the way. A stepped tear perforation is created which prevents dust from entering when it is resealed. This opening variant is created into the material using a so-called counter-scoring.
Our eopti-box makes use of exactly this principle of counter-scoring
When opened, the cardboard material is “split” in the middle at the so-called release surface and is only half as thick in this area after opening. One half of the paper thickness is removed from the folding box cardboard in the engagement area by pulling the cardboard material in the direction of the opening perforation after pressing in the finger hole. The second half of the paper thickness remains in the folding box. This simulates conventional paper backing, which is naturally many times thinner than the actual folding box board.
In order to increase the elasticity when engaging with our ecopti-box, there is another incision at a short distance from the release surface, which is also made into the material from the outside of the folding box. This means that the cardboard material, which is still full thickness in this area, springs slightly during engagement and allows the fingers to penetrate deeper into the folding box body. The wavy line that becomes visible when opened serves as an intervention and simultaneous cut protection.
A patent has been submitted to the European Patent Office for the opening variant for tissue folding boxes specially developed by Mugler Masterpack, which does not require window gluing with kraft paper, and is currently being examined.
