In less than three minutes, you’ll see every critical part of a bottle... and be able to understand how they contribute to packaging performance. For example, did you know that if you describe the parts of a bottle beginning from the top that you are actually starting at... the finish? With a name like that, you would never think it is the part of the bottle that is completed first.
