When importing blanks from China to make the PET bottles for bottling, how much does each batch cost and what are the general quantities/batch of blanks?

Any help would be appreciated as this is for a value chain analysis of the bottling industry.

So nobody can help me out on this? I just need a basic price range on the cost of supplying PET bottles that will then be filled with a beverage.

Patience grasshopper....
Try going to a package supplier listed in the index of this website. Those guys could help you out considerably.
When you talk to these guys have your ducks in a row. Don't be as vague as you are in your original question. You will need quantity breakdowns, volume description(size of bottle) Port of entry,payment terms(cash or credit), cap size( a 20 oz bottel can have differing capping needs), how are you going to fill the bottle( different bottles have differing manufacturing needs). Are you going to order the blanks and blow them yourself or do you actually want the bottle pre-blown and ready for label and fill?
Your question may not have been answered because it was not posed in the manner to which could lead someone to easily answer it.
