In packaging design, the combination of design, graphics and materials plays a major role. A conception of accessories this means closures or labels, is also very important. Capsules are one of the subtle, yet important features. For wine bottles, die-cuts covering only the top of a cork are used beside complete capsules. Tin or aluminium capsules range  among the finest and most successful variants in marketing. However, there are also plastic (PVC especially) or laminate (PVC/Al) capsules. So called heat-shrink capsulesare traditional capsules manufactured from plastics in particular.
