Abstract

PURPOSE: An expandable packaging band composed of a mixture of polypropylene and a specific amount of high-density polyethylene or ethylenevinyl acetate, thus resisting to rapid expansion of stress because of its specific elongation at breakage and elastic recovery.
CONSTITUTION: Polypropylene is combined with 0.5W20wt% of high-density polyethylene and/or ethylene-vinyl acetate containing 65W95wt% of ethylene and they are extruded through orifice into billets, which are then cooled. The resulting billets are drawn at 60W140°C at a draw ratio of at least 4 and heat treated at 140W165, preferably 150W165°C. The products show elongation at break of more than 30% and elastic recovery of more than 80% and 5% elasticity of 50W230kg- f/mm2.
