Tissue paper is commonly wound onto cores (board rolls) made from strips of paperboard wound on a horizontal spindle while simultaneously being bonded layer to layer; the result is a continuous core that is then cut to the desired length (Figure 8.37). The paperboard has a basic weight of 120-160 gm-2, with two to four […]

Manufacture of Tissue Paper Products
The manufacture of tissue papers is an important sector of the paper industry, as a wide variety of tissue papers is now available for daily use. The adhesive systems and raw materials used for these applications are tailored to the needs of the tissue products and the machinery used to produce them. The adhesive systems […]
Cigarette Production
One special application of adhesives in the use of paper is the production of cigarettes. At present, cigarette rods are manufactured at a line speed of up to 750 m min-1, during which the cigarette papers are side-seam-bonded using dispersion adhesives and starch-based adhesives are applied by means of discs or nozzles. One particularly high-demanding […]
Membrane Bonding
Membrane bonding is a special way of creating a tamper-evident closure for jars. To this end, a membrane made from coated paper or aluminum foil, for example, is bonded to the glass rim. When the jar is opened, the bonding is broken, leaving an obvious visual indication that the jar has indeed been opened. The […]
Tamper-Evident Bottle Closures
The purpose of a tamper-evident bottle closure is to comply with statutory regulations and to issue a guarantee for producer bottling and product integrity. Either hot melts or waterborne adhesives can be used, as necessary and depending on the bottle material. Both adhesive systems must meet high demands as to the initial strength, detachabili — […]
Inline Labeling
As with precoated labels, adhesives used for so-called ‘inline’ labeling must be selected correctly to ensure high-quality labeling. For inline labeling, either waterborne adhesives or hot melts are applied during the labeling process — that is, at the same time as the labels. Both adhesive systems can be combined for special applications. Waterborne Labeling Adhesives […]
Pressure-Sensitive Labels
Although, currently the European label market (Figure 8.33) is dominated by precoated pressure-sensitive labels, this market share of about 50% is expected to grow further. Self-adhesive labels are usually applied as tags, they adhere well to the majority of materials, and they can be made from either papers or plastic films. Precoated PSA labels are […]
Labeling
Today’s produce is unimaginable without labels, which are used to inform, decorate and aid logistics. In modern shopping centers and supermarkets, labels help to provide an alluring appearance to the products that must be self-sellers. Labels play a particularly important role in the beverage, cosmetics and cleaning products industry sectors as they bring products ‘to […]
Pallet Securing
Cargo is commonly transported in palletized unit loads, with individual packages stacked on each other on a pallet base. In order to secure the load to the pallet during transport, one solution is to use plastic wraps; however, because this creates much packaging waste, such wraps are being increasingly replaced by palletizing adhesives (Figure 8.32) […]
Carton Closing
Bonding is the most important method of closing packages made from paper, cardboard or paperboard. Depending on the automation level of the packaging line, the design of the machinery and the demands placed on the packages during transport and storage, one of the following systems is used: • hot melts • PSA packaging tapes • […]
