PET Preform Size & Weight Chart
A PET preform size chart lists preforms by neck finish and weight. This one covers every preform in Nawkiran's catalogue: 75+ product types, counted exactly as 79 combinations of family, neck finish and weight. Neck finishes span 22–120 mm and weights span 5.5–101.5 g.
Updated
Each row is one neck finish, and the weights beside it are the weights made in that finish.
- Neck finish is the shape of the preform's mouth, with its thread and support ring. The catalogue lists it in millimetres, and your cap must be made for it.
- Weight is the mass of one preform in grams. It is not the volume of the bottle.
- Family is the catalogue range a preform belongs to. It follows what you will fill, so start there if you are unsure.
- Every weight listed can go into an enquiry. Send the family, neck finish and weight.
