By carrying the message of a brand, labels can influence the customers decision. The choice of the right adhesive depends on more than just the flawless exterior appearance of the label. Special adhesives from the product series Jowat-Toptherm® and Jowatherm® facilitate a strong, flexible, and clean bonding of labels to containers, as well as comfortable handling and an attractive appearance. Some container types, for instance PET bottles, may expand or collapse depending on the ambient conditions. To ensure this does not affect the superior appearance, the adhesive must be able to compensate for the different size of the bottle and the label. In addition, the clean adhesives from the Jowat-Toptherm® product series for labelling do not bleed through even thin and sensitive paper labels.
Pressure-sensitive adhesives based on polyolefin for labelling in the beverage industry.
Jowat-Toptherm® products based on polyolefin also impress with a long thermal stability in the melt, low stringing during application, as well as reduced energy consumption. The adhesives are characterised by optimum adhesion to containers made from a wide range of materials like PE, PP, PET, aluminium, sheet metal, or glass. Rubber-based adhesives from the Jowatherm® series have an outstanding surface tack, and have been developed especially for containers of carbonated drinks. The adhesive products from both series have been approved according to food contact regulations.
Polymers are responsible for creating the inner strength, the cohesion of the bond. Modern, tailored polyolefin-based polymers are highly suitable as raw material bases for labelling adhesives, since the balanced cohesive properties will give the adhesive high strength and excellent flexibility. The new Jowat-Toptherm® adhesives provide higher-than-average initial tack, which is a major factor when labelling with wraparound foil or split paper labels. The processing window permits outputs of up to 48,000 bottles per hour.
Production can profit from the lower process cost for polyolefin-based hot melt adhesives. The numerous advantages of this group of adhesives are already known on the market from the application carton closing, and are now applied to the labelling process. The PO basis makes those drawbacks obsolete that were known from the processing of labelling hot melts based on EVA or rubber, like burning, cracking or separation. The reduced stringing effect during application, and the high heat resistance in the melt, limit cleaning operations and allow for longer maintenance intervals. The new raw material basis promotes a highly stable viscosity, with the consequence of a good and even flow and transfer performance during application.
