Bischof + Klein (B+K) is one of Europe's leading full-service providers of flexible packaging and technical films. We produce high-quality flexible packaging made of plastic and laminates as well as technical films for almost every application. Bischof + Klein is a modern family business. This includes strong roots at its German locations in Westphalia and Bavaria as well as production facilities abroad and an efficient international sales network. The balance between ecology and economy and the social needs of employees and society is an essential aspect of all business decisions. B+K has been awarded the German government's 2014 CSR Prize for its responsible corporate action. B+K produces on modern systems for mono-/co-extrusion, gravure/ HD-flexo printing, solvent/solvent-based/solvent-free lamination and coating as well as for extrusion lamination and coating. Highly developed assembly technology with product-specific equipment for sealing, welding and gluing enables individual production according to the customer's requirements. The main plant in Lengerich, where all processes for the production of flexible packaging are bundled under one roof, is probably unique in the world. Technicians and development engineers will find a unique spectrum of production possibilities here. Motivated employees are our potential for success. Their motivation is based on recognition and identification - values that we promote and demand. Competence presupposes a willingness for lifelong learning and the desire to develop one's personality. B+K promotes both with an extensive further training programme.
