These days, technical superiority is crucial, but this is not the only consideration. In this age of image, the world is asking for more in terms of consumer perception with creativity in design and colour. The product must attract our eyes and brain and deliver the marketing message in a way that appeals to the consumer… then they buy it. A SLEEVE LABEL that achieves the highest consumer impact helps the product differentiate itself from, and have an advantage over, the competition. Alfatherm TD (transversely oriented) shrink films are nowadays recognised as the ideal solution when we are looking for a printing substrate, sleeve label converting, tamper evident seals, wine caps and promotional packaging. Our shrink film range gives our customers, printers and converters, the widest choice of possibilities in terms of shrinking characteristics and printing/application specifications and techniques.
