What is NNPB?

Answer 1

NNPB = Narrow Neck Press and Blow.

This is a glass bottle forming process,wherein very light weight glass bottles are made compared to the traditional blow and blow process of making glass bottles.

NNPB bottles are lighter by around 30% compared to Blow and Blow process,and the bottles produces have evenly distributed glass,and so stronger than blow and blow glass bottles.

But this process requires hitech glass forming machinery,expensive mould items and very skilled labour.

Most of the renowned glass bottle making companies are now making bottles using this technology.
