The downside of online shopping and free delivery orders: tonnes of cardboard and paper waste that is not disposed of correctly. Filler materials and adhesive tapes often end up in the waste paper and have to be meticulously separated before recycling processes are even possible. Holistic recyclability can only be achieved by using single-material packaging that does not use plastics. This is where tesa comes in with its new product solution tesa 51344.

Application on mailing bags and cardboard boxes

tesa 51344 is a paper-based tear strip for mailing envelopes and cardboard boxes. The tape's innovative, strong paper backing is coated with an adhesive compound that ensures reliable adhesion even to cartons with a high recycled content. Once the packaging has been disposed of, the tape can be recycled along with the packaging material. tesa is one of only a few manufacturers on the market to offer this innovation in its portfolio, providing customers in the corrugated cardboard industry with a more sustainable product that is also suitable for automated production lines.

"With this new product solution, we are offering our customers a fully integrated and more sustainable solution for the production of packaging and shipping cartons. We produce tesa 51344 without solvents, and the paper used for the backing comes from controlled sources," says Frank Domann, Corporate Marketing Director Industrial Markets at tesa. "Developing products that contribute to sustainability is a strategically important goal for tesa. And we also want to support our customers and partners in achieving their sustainability goals. With tesa 51344, our customers get a more sustainable product for their manufacturing process, while at the same time we improve the eco-balance of shipping boxes or mailing bags," adds Domann.

Classified as recyclable

The fact that tesa 51344 is recyclable and can thus be disposed of with the cardboard material is also confirmed by the recyclability test in accordance with PTS-RH 021:2012. This method determines the content of dissolved, colloidal and suspended substances in the aqueous phase of the fibre suspension after dissolution using a laboratory scale. In the further development phase, the innovation also passed several application tests with different types of cardboard and corrugated board with flying colours. The adhesive tape convinced in the tests with its high adhesive strength and reliable opening behaviour.
