In glass bottle manufacturing, NNPB stands for Narrow Neck Press and Blow.
It is a specialized production process used to manufacture high-quality, lightweight glass containers. This technique is particularly effective for bottles with small openings, such as beer or soda bottles, as it allows for a more uniform distribution of glass in the bottle walls compared to the traditional "blow and blow" method.
Key Benefits of NNPB:
Lightweighting: It enables the production of thinner, lighter bottles without sacrificing strength.
Precision: By using a metal plunger to press the glass into the initial "parison" shape, the thickness of the glass is controlled more accurately.
Cost Efficiency: Lighter bottles require less raw material and reduce transportation costs, which is highly valued by large-scale beverage brands like Tito's.
