Beschreibung
Zusammenfassung:	The invention provides a hot-melt composition comprising a thermoplastic elastomer, a tackifier, a wax and a polyolefin resin, the wax having a softening point (R & B system) of 140 to 160 DEG C. The hot-melt composition can be easily applied to the mouth-neck portion of a metal can and can be excellently produced. Even when placed under a high-temperature condition, the sealing material that is formed exhibits excellent heat resistance maintaining the sealing.
