<p>PROBLEM TO BE SOLVED: To provide a lightweight multi-layer plastic bottle which is made thin-walled and weight-reduced, having good moldability, and on which unbalanced wall-thickness or deformation does not occur when molded, and which is excellent in surface luster, transparency, rigidity and heat resistant properties, and in the ability to be impervious to contents included therein, and which has improved impact-resistance. SOLUTION: In the lightweight multi-layer plastic bottle having outer layers and a main layer, the main layer is constituted of high-pressure process low- density polyethylene being greater in Olsen flexural rigidity than the resin composition constituting the outer layers.</p> |
