Germany-based Inotech develops new technology to produce multi-component preforms for PET bottles with individual color, material combinations without need for separate assemblies

NABBURG, Germany , October 13, 2011 (press release) – INOTECH Kunststofftechnik GmbH has developed and created a brand new and unique technology to produce multi-component preforms.

Multi-component moulding is a multi-step moulding process that produces preforms with two or more integrated components. Out of this invention INOTECH created two patent applications for performs and bottles.

The multi-component perform enables one to produce bottles with individual color and material combinations without any separate assemblies. You can create unique 3D effects or transparent areas for windows and filling levels. From now on it is possible to cover critical areas and to solve functional problems, also without any following assembly step.

INOTECH is convinced to improve physical properties like heat resistance or mechanical resistance with a qualified choice of material combinations.

In development together with Merck KGaA in Darmstadt we are creating a bottle with special pigments (Securalic pigments) to have a brand and product protective packaging solution.

Together with a research company INOTECH is also focusing the shelf life time of beverage. Instead of using the currant technologies of hot filling, preservatives or aseptic filling, this new development is working with an anti-microbial material as a partial inner layer of the bottle. The results are unbelievable: filling and storage of fresh milk and orange juice in the new bottle at 30°C reduces bacteria in the product and enlarges the shelf life time.

The Multi-Component-Preforms can be produced with Standard IR or NIR Heating Systems or on Krones new FlexWave (microwave) System. So one can handle them like standard preforms. Some adjustments have to be done on the process according to the preform design, color and shape. Some specific designs may only be possible to be heated on the FlexWave System.
