Since it was established, it has reached the top level of quality and hygiene in Plastic Industry without compensating on quality and service in accordance with the goals which have been intended to improvement. Our company, which made packaging for cologne and cosmetics industry until the year 1998, from this date on, invested in ‘’coex’’ and ‘’pet’’ machines which are produced at lower level in our country under the quality policy by improving it’s substructure at a level of advanced technology. Coex, which is the highest level of plastic blowing industry, consists of three layers and provides the liquid become healthy and shelf-stable through polyamide that is in bottom layer. Due to the fact that it reduced the oxygen permeability in minimum level, coex became irreplaceable in agricultural pesticide sector. We have been producing coex bottles from 50 cc to 30 lt and also their caps through our injection section.
