22gram USD 0.0352
Only 1piece preform different will at 0.0064. If 3millions per year production factory will different at USD 19200
Different weight will effect the strong and thickness of the bottle. Too strong or too thickness is not necessary for bottle water.
Also the bottle design will effect the thickness. Like square bottle will cost more materials than round bottle. That is why most bottle water use round design.
An good bottle blow molding machine will produce clear and good quality plastic bottle with less weight preform. Not only save materials cost, but also produce good quality bottle.
