The powerful Jowat Toptherm® polyolefin hot melts impress with a high yield and clean processing, reducing maintenance costs and downtimes in packaging processes. Whether tray assembly, folding box sealing or wrap-arounds – the state of the art adhesive formulations with a low impact on resources keep processing costs low. The latest trends in the industry, such as shelf-ready packaging, provide significant benefits at the point of sale for retailers and consumers. Due to the attractive secondary packaging, the articles can be put directly onto the shelves. Special tray shapes with removal cut-outs provide a convenient and safe way of taking the article out of the secondary packaging. The 180° flaps on these cut-outs, however, represent a challenge for the bonding process due to the high restoring forces. To meet the requirements of this application, Jowat has developed special powerful adhesives with superior processing characteristics and high initial strength.
Jowat Toptherm® products provide the high heat resistance required for the sealing of cardboard boxes. This characteristic, however, is not only needed for hot filling. Adhesives with a high heat resistance are also essential for packaging that is exposed to high temperatures during transport. In addition, these adhesives are characterised by a good cut-off at the nozzle, excellent feed performance, and high process stability. For deep-freeze packaging, Jowat also provides special adhesives with a good flexibility at very low temperatures, excellent adhesion and high resistance to humidity and mechanical stress. This combination ensures a permanent bond.
Another major concern in the packaging industry is the risk of harmful substances migrating from the packaging material into the food. Folding boxes for food packaging are manufactured more often from recycled paper, which requires an additional barrier to protect the goods against a potential migration of varnish or print ink components. The barrier function is provided by films, or by dispersion or extrusion coatings that are applied onto the interior side of the folding box. In general, sealing folding boxes used for primary packaging is a very demanding application, due to the difficulty to assess the surface properties of the material. Jowat adhesives developed for closing primary packaging made of recycled and virgin fibre paper provide excellent results on the most different barrier coatings. These adhesive are characterised by a good cohesion at unfavourable counter pressure, plus superior adhesion to surfaces with finishing, film lamination or varnish coatings. Meeting highest requirements, these adhesives also impress in applications with sensitive products due to the excellent resistance to essential oils, such as the bergamot oil in tea.
