<p>PURPOSE:To improve transparency and eliminate non-uniform thickness of the titled container, by making injection orientation blow molding of a random copolymer of propylene and ethylene whose ethylene content is 1-6wt% and a melt flow index is 4-50g/10min. CONSTITUTION:A molded container which is superior in transparency and having non-uniform thickness is obtained by applying injection orientation blow molding method to a random copolymer of propylene and ethylene whose ethylene content is 1-6wt% and a melt flow index is 4-50g/10min. As for the molded container, as transparency of the same becomes favorable further a, nucleating agent can be loaded, and in this case, the nucleating agent of less than 1wt% is favorable to a propylene-ethylene random copolymer. In addition to the above, additives such as an anti-oxidizing agent, an ultraviolet absorbing agent, an antistatic agent, a coloring agent and lubricant, the other resin and elastomer can be added to.</p> |
