6New technologies open new markets Focus Injection stretch blow molding with barrier Efficient economical and custom made Greiner Packaging has been working with Mould Matic part of the HAIDLMAIR GROUP since 2009 to further develop the injection blow molding procedure Greiner Packaging is now in a position to offer its customers numerous advantages thanks to Kavoblow 03 15 unique packpaper Injection stretch blow molding is among the most common ways to manufacture hollow parts in the plastics industry There are two variants to this process In the 1 step method the so called pre forms are blown immediately after the injection process while still warm while in the 2 step me thod the preforms are cooled and stored after the injection procedure Greiner Packaging is among the industry pioneers in the 1 stage method in particular What is different about Kavoblow The preforms are line produced and blown in multiple rows This is a considerable advantage since more production pieces than previously possible can be made within a shorter period of time Greiner Packaging occupies a niche especially in regard to the number of pieces With the 1 step method it was previously possible to manufacture only up to five million pieces on one machine economically Now however the company is able to offer cost ef ficient manufacturing even beyond this quantity The technology therefore combines the high quality of one step production with the efficiency previous ly reserved for two step systems Top quality free of impact marks while ensuring utmost flexibility different materials such as PET PP PA and PE can be used but multilayer applications are also possible Packaging with non round and off cen ter mouths can likewise be manufactured as can containers in the most diverse colors shapes and sizes This also allows the cost efficient production of customer specific special editions Packaging is changed much more frequently these days than it was a few years ago consumers expect change This naturally represents a challenge for product suppliers and in turn for us as packaging pro ducers Therefore our job is to respond to these demands flexibly and in a cost efficient manner We have succeeded magnificently with Kavoblow says Günter Ausserwöger Sales Director Kavo Maximum benefit through the combination of two technologies However much more is being demanded of packa ging these days in the food sector Aside from eco nomical production they not only have to stand out visually but must also protect the filling to the greatest extent possible Consumers expect in creasingly longer shelf life but without sacrificing naturalness and sustainability Preservatives ad ditives or ultra high heating are increasingly be coming things of the past Following this trend Greiner Packaging is combining its Kavoblow tech nology with mbt multi barrier technology hel ping foods achieve longer shelf life directly in the packaging With this technology a special barrier layer such as EVOH or PA is embedded in a stan dard plastic such as PP or PET This achieves a higher oxygen barrier for packaging and protects the filling from external effects thereby substanti ally increasing the food shelf life The barrier lay er is introduced during production of the preform with injection stretch blow molding with Kavoblow Focus
