| 摘要 |
<p>The process is characterized by a better distribution of the material both in the neck region and in the preform body, giving a bi-stretching ratio of the order of or higher than 30 % than the conventional ratio despite of the reduction of the preform weight, owing to a modification of the configuration of the polymer molecular network.</p> |
