GEA OxyCheck

GEA OxyCheck

GEA OxyCheck is an in-line quality control system that checks the oxygen (O2) content and seal integrity of every single Modified Atmosphere Pack (MAP) that leaves your thermoformer. It eliminates the need for time-consuming sample testing that wastes packaging material, contents and only tests a small percentage of the packs.

Consumers, retailers and producers all benefit

Consumers want safe, fresh and healthy packaged foods, retailers seek prolonged shelf-life and excellent visual appeal, and food producers must deliver products in accordance with agreed quality specifications. All will benefit from the new GEA OxyCheck, which has an essential role in ensuring food in Modified Atmosphere Packs (MAP) reaches the consumer in perfect condition.

In-line quality control system for MAP on GEA thermoformers

The GEA OxyCheck uses non-invasive technology to accurately measure the O₂ content in sealed packs immediately after they are sealed on a GEA PowerPak thermoformer. Unlike common techniques, which only inspect sample packages randomly taken from the line, the GEA OxyCheck inspects every single package without damaging the film or breaking the seal. A second measurement station on the thermoformer re-checks the O₂ content to recognize leakage. Packages that don’t meet the specifications are automatically rejected and do not enter the supply chain.

Unique sensor spot technology

The system uses a unique sensor spot printed on the inner side of a lidding film. The spot is food safe and conforms to all relevant regulations for material having food contact. The GEA OxyCheck uses the fluorescence properties of a special dye in the spot. The thermoformer-mounted optical sensors project light on the sensor spot and measures the wavelength of the light that fluoresces from the dye to accurately determine the O₂ content.

For new and existing GEA thermoformers

The application is now available for GEA PowerPak horizontal thermoformers as an option on new machines and a retro-fit upgrade on the existing PowerPak NT machine generation with MAP capability. The GEA PowerPak has a rated speed of up to 20 cycles per minute, and the GEA OxyCheck operates at this line speed meaning throughput of the thermoformer is practically not affected by the in-line MAP quality control system.

Key benefits

100 percent certainty because every pack is inspected for O₂ content
No packaging material or contents are wasted thanks to non-invasive measurement technique
Fast and efficient, thanks to being an in-line automated process
No time wasted for tracing when an out-of-specification pack first occurred
Significantly reduced risk that an out-of-specification pack leaves your site
