A laminate sheet, particularly an aluminium-based laminate comprises polyethylene having a density of 0.90-0.96 g/cc, a polyethylene-based film having a melting temperature of less than 240° C.; low density polyethylene in order to provide high adhesion; an aluminium barrier film, and a polyethylene-based film having a sealing property. Furthermore, the laminate sheet may further comprise a blown film or a dry laminate for making a tube and a tube shoulder in order to prevent flavor loss of the products packaged therein and without stress crack.
