The acid modified polyethylene resin and the crystalline polyethylene resin are selected so that a temperature at which {HEAD ~ the resin} has a crystallinity of 60%, Tmα60, is lower than {TAIL ~ a temperature} at which the resin has a crystallinity of 60%, Tmβ60, preferably lower than a temperature at which the resin has a crystallinity of 70%, Tmβ70, more preferably lower than a temperature at which the resin has a crystallinity of 80%, Tmβ80
