Process for optimizing preforms, and lightened preforms thus obtained |
摘要 |
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 modication of the configuration of the polymer molecular network. <IMAGE> |
