Why Blow Molding for the Cosmetic industry?
Thanks to the use of high-density polyethylene (HDPE), bottles benefit from excellent chemical resistance and opacity. This material is commonly used for shampoo and detergent packaging.
Thanks to extrusion blow molding technology, unlike other production methods, it is possible to create bottles with oval and ergonomic sections, inclined shoulders, and high design freedom, combining functional shapes with aesthetic material finishes.
With multi-cavity or neck to neck configurations, very high productivity can be achieved, while investment costs remain lower than injection molding machines.
Neck to neck. Double productivity.
In the cosmetic sector, Neck to Neck (NTN) technology configurable on Techne electric extrusion blow molding machines enables very high production volumes with fast and continuous cycles, ideal for large series of containers.
It retains the typical advantages of blow molding—shape versatility, customized design, and reduced unit costs—and integrates with multi-cavity systems to increase efficiency and production yield.
Fast color change, continuous production.
Techne’s system reduces downtime during color change in bottle production.
Thanks to the PVD coating applied to the extrusion heads, the plastic material flows better on the metal surfaces, reducing adhesion and facilitating cleaning.
The result is a more efficient process with lower material and energy waste, consistent product quality, and more flexible and sustainable production.
