Develey / Ketchup

It is light, shatterproof, transparent, and optimally protects the filling, thanks to its high oxygen barrier – the unique Kavoblow plastic bottle with multibarrier technology (MBT) that Greiner Packaging has introduced on the market for the German food company, Develey. The bottle combines three important packaging properties in one single product – high barrier, high transparency and temperature stability – and has therefore become a clear competitor of glass bottles.

Kavoblow is an innovative advancement of 1-step injection stretch blow molding. More production pieces than previously possible can be made within a shorter period; the best quality, free from impact marks and with high design flexibility, can be produced economically. The packaging exhibits a higher oxygen barrier in combination with MBT, giving the ketchup a particularly long life even without any added preservatives. The barrier layer is directly introduced in the injection stretch blow molding procedure, which guarantees efficient production. The Kavoblow technology even makes it possible to produce PP barrier products with a glossy surface and promises a closed EVOH layer from the injection molding base on the bottom of the bottle up to the thread. Especially for products that require high barrier, hot filling and transparency – such as ketchup, sauces or sugos – Kavoblow MBT is the ideal packaging choice, as production is simple, efficient and many design variations are possible. Greiner Packaging is one of the absolute pioneers on the market here.

High oxygen barrier meets transparency and temperature stability

The Kavoblow MBT bottle is a combination that has never before been on the market and makes the product innovative and unique,” emphasizes Günter Ausserwöger, Product Group Director at Greiner Packaging. “High barrier, high transparency and temperature stability can be combined in a single product.” The innovative bottle was first implemented for Develey; the company produces premium ketchup. The ketchup puts value on natural ingredients and top quality, the brand dispenses with the use of preservatives and uses a particularly high concentration of tomatoes. The packaging therefore has to have an excellent oxygen barrier that guarantees long life for the product.
