Descripción de la aplicación
El acabado de impresión de primera calidad crea efectos excepcionales y hace que los productos sean más atractivos para los compradores en el punto de venta. Este aspecto superior está respaldado y protegido por una laminación de la superficie con varias láminas de acabado. Los adhesivos para esta aplicación deben proporcionar una adhesión excelente a las láminas, así como a los sustratos impresos. Durante los últimos años, en Jowat hemos estado desarrollando una amplia gama de adhesivos de dispersión. Estos modernos adhesivos de laminación están caracterizados por una formación de espuma y cantidades de aplicación mínimas, así como por propiedades de flujo excelentes. La gran fuerza de fijación y resistencia al corte, así como una alta durabilidad garantizan un procesamiento posterior óptimo, como el ranurado, el dentado y el gofrado.
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.
