Introduction

• What is the optimal blowing temperature?
• What is the optimal heat profile in the preform wall?
• How does PET absorb infrared energy and how can this knowledge be used to improve bottle properties?
• How do material properties and stretch ratios affect blowing behaviour?
• How can optimal wall thickness distribution be achieved?
• What amount of oven cooling should be used?
• How does blow air timing affect bottle properties?

These are some of the questions that arise when blowing PET bottles. This book gives comprehensive answers for both novices and industry experts. Machinery, process, and auxiliaries are covered in never before published detail. An extensive trouble-shooting section complements the machine and process descriptions.
