La finitura di stampati di alta qualità crea effetti straordinari e rende i prodotti più attraenti per gli acquirenti nel punto vendita. L’aspetto superiore è supportato e protetto laminando la superficie con un diverso foglio di finitura. Gli adesivi per questa applicazione devono fornire un’eccellente adesione alle pellicole e ai substrati stampati. Negli ultimi anni, Jowat ha sviluppato un’ampia gamma di adesivi a dispersione. Questi moderni adesivi lamellari sono caratterizzati da una quantità minima di schiuma e quantità di applicazione e da eccellenti proprietà di flusso. L’elevata resistenza e resistenza al taglio e la lunga durata assicurano processi di discesa ottimali, come scanalature, intagli o goffrature.
Products from the Jowacoll® 764.xx product group have been consistently optimised over the last years to improve their performance, for instance mechanical processing characteristics, cutting resistance, coating weight, gloss, and resistance to mechanical stress, e.g. due to embossing or fold burning. In addition, the new product generation also includes several adhesives that are approved for food contact. Which of the modern laminating adhesives is the best fit for an application depends on the machine type and the application method used, as well as on the specific requirements. However, the adhesive choice can also be influenced by what type of paper or film is to be bonded and by whether it has been printed conventionally or digitally.
The table below provides an overview of our dispersion adhesives from the product series Jowacoll® for laminating printed sheets. The product range comprises different product types with special performance characteristics adapted to the general process requirements in laminating applications.The products have been developed to meet the different requirements which arise from the production process as well as from the different carrier substrates and lamination materials. If the laminated compound is exposed to high mechanical stress during downline processing or if the films to be processed have a high rigidity (e.g. PET or acetate films), it is advisable to add 1.5 – 5 % of crosslinking agent Jowat® 195.70 or 195.79 in the case of food packaging.
