NNPB is a revolutionary process that not only controls the distribution of glass inside the container, but also reduces the weight of glass by 33% without having any adverse effects on the performance of the glass containers. HNG is the first to introduce and commercialize this technology in India. .
HNG introduced the narrow neck press and blow (NNPB) technology in 2007-08, which lead to the reduction in the consumption of molten glass per bottle without compromising on product strength. Facilitating superior glass distribution, this technology reinforces the bottle's resistance to pressure on the filling line. It also leads to a decrease in logistics cost and increase in consumer acceptability of the bottles
HNG invested a capital of Rs. 100 Cr. to introduce this technology in India. On one hand, this technology enabled the company to reduce production costs and wastages; and on the other, it strengthened capacity utilization. Through NNPB, HNG strives to remain competitive with other packing alternatives and continue to be the market leader in India.
Narrow Neck Press and Blow Vs Blow and Blow technology:
The parison facilitates precision in control
Enhanced glass distribution throughout the bottle
Lighter in weight, hence a lower consumption of molten glass
