Flexible and strong, sacks and bags ensure a safe transport of goods such as free flowing bulk material. To protect the goods from mechanical stress and moisture, this packaging is usually manufactured from a composite material consisting of several layers of paper and plastic foils, paper and paper, or paper and aluminium foils. Special Jowacoll® dispersion adhesives used in manufacturing ensure, for instance, a fibre-free separation of the paper-plastic compound. In addition, the adhesives are characterised by superior feed properties, are easy to clean, provide a reliable, permanent adhesion to the different substrates, and meet the demands of food contact regulations.
