Résumé :	FINAT defines low-temperature adhesion as the ability of pressure-sensitive coated material to adhere at temperatures below 5°C. Today, many applications require adhesion that must be maintained at temperatures of -25°C or lower. One of the main characteristics of pressure-sensitive adhesives (PSAs) is their viscoelastic character, which allows optimal mobility for wetting substrate surfaces in order to bond and obtain maximal adhesion, while absorbing energy as viscoelastic deformation to maintain an effective bonding. Viscoelastic character of an adhesive is given by the elastomeric polymer present in its formulation. PSAs used in applications like tapes and labels for frozen food packaging and other applications in cold environments require special attention for the ingredients selection and, more specifically, in the polymer selection. At temperatures below the glass-transition temperature (Tg), a polymer has a brittle consistency and loses its deformation capacity. Consequently, an adhesive made with that polymer loses its mobility and elastomeric capacity to maintain the adhesion. It is therefore important to select a polymer that will adequately maintain its elastomeric characteristics at reduced temperatures; this is a low-Tg polymer.
