Description

A preform is a blank for the production of bottles and cans from PET (polyethylene terephthalate) by blow molding, that is, a blank that is needed to blow a bottle using a mold and blow molding machine. The neck part of the preform is the neck part of the future container, therefore PET preforms are the most important and distinctive advantage - high accuracy and repeatability of the neck part.

The weight of the preform directly depends on the volume of the blown bottle; the requirements for the strength and barrier characteristics of its walls are also taken into account.
The approximate ratio between the weight of the preform and the capacity of the resulting bottle is as follows:

Preform weight, gr. / Bottle capacity, liters
20 g - 0.33 l
23 g - 0.5 l
39 g - 1 l
42 - 44 g - 1.5 l
48 g - 2 l
87 g - 3.5 l
710 - 770 g - 19 l

Given the strength characteristics, the weight of the preform will vary. For example, to blow a bottle of 2 liters of still water, a preform weighing 48 grams is needed, and for carbonated water, the weight of the preform will increase to 52 grams.
