why a water bottling company choose to produce its own plastic water bottles:

There are several reasons why a water bottling company choose to produce its own plastic water bottles:


PREFROM FOR water bottle

36 gram preform is most usually use to produce 1500ml plastic bottle. And 36gram preform just cost $0.056 usually while a 1500ml cost $0.08 or more. It will help you save large number of cost per month. The smallest water bottling line will production 300k piece bottle water.

Empty bottle not only take room but also easy been crush while freight. It take room about 10times than preform. So that the freight cost is 10times than preform. What is more, the empty bottle easy been crush when freight. But the preform is strong enough to freight without any damage. 1cube can filler 10k piece preform but only filler 1k piece empty bottle.

Turbidity/NTU ≤1
Smell and tasteNo odor or odor
VisibleNot detectable
Pathogenic bacteria (Salmonella, Shigella, Staphylococcus aureus)NO ALLOW
According the Pure Water Hygienic standard for Bottled/Sachet (PWHS 2021)

In the above form. We can saw that the any bacteria is not allow to detected. But as we know there are a lot bacterias in the air and human being hand. And the water package process can not avoid the human being and air. It is happened in the factory. The factory must have air and human being.

The water been purifier by RO system and mixer with Ozone. It is easy for control its quality. Then the next key control is the bottling process. A lot bottle water company buy the plastic bottle from supplier and freight to water bottling factory. That is a big problem. The freight process is too long time to lead the bottle outside and inside bactrias by air or car.
