Trendsetter with the edge in know-how

Barrier technology

Modern consumer demands for longer product shelf lives without preservatives while providing good product protection are increasing. Greiner Packaging has followed the trend and is investing heavily in developing barrier technologies for plastic food packaging. This technique involves layers of various materials that protect the filling. By placing a great deal of value on having a wide range of offerings of plastic food packaging for different target groups, Greiner Packaging has succeeded in driving a variety of different barrier technologies forward

IBT (inert barrier technology)
= barrier through coating

Cups are placed in a chamber, which is then placed under vacuum. Afterwards, oxygen and a gas containing silicon are piped into the chamber and a plasma is generated using an electrode. This produces a wafer-thin silicon oxide coating on the cups.

The barrier layer is flexible and can undergo sterilization and pasteurization. It has no effect on the transparency or weight of the cup – an important factor with respect to logistics and CO2 emissions. The coating of this type of plastic food packaging has no effect on disposal or recycling, either.

MBT (multi barrier technology)
= barrier through several layers

A greater oxygen barrier can be achieved by embedding a special barrier layer such as EVOH or PA into a standard plastic, such as PP or PET. The filling requirements can be addressed individually, depending on the plastic systems chosen.

This plastic food packaging technology is used for extrusion, sheet extrusion with subsequent thermoforming for cups and bowls as well as for injection strech blow molding for bottles and containers. Multi barrier technology allows the production of highly transparent products while at the same time offering the possibility of hot filling - a clear advantage over other packaging solutions on the market.
