Packaged fresh: MAP technology for extended shelf life

Long Dwell sealing

Packaging machinery that has been designed to take full advantage of Modified Atmosphere Packaging (MAP) technologies can improve product freshness, reduce the amount of added preservatives and extend shelf life.

 

It is estimated, that the appropriate packaging combined with optimal temperatures delays food spoilage by as much as 800 per cent1. MAP technology is based on adding protective gases into a packaging environment. As fresh foods spoil within different spans, blending the right percentages of gases is crucial. The three gases most commonly used for MAP are oxygen (O2), carbon dioxide (CO2) and nitrogen (N2). A closed packaging environment, as for example one with a high-barrier film, is filled with a protective gas mixture which substitutes the atmosphere inside the package, inhibiting the chemical reactions that cause food spoilage.

 

 

MAP with the appropriate packaging machinery

Precondition for successful application of MAP is packaging machinery providing hermetically tight seals. The choice of flow wrapping machinery is crucial. Bosch can fit all of its flow wrappers with MAP equipment like mixers, controllers and gas analyzers. However, MAP technologies are particularly well-suited for our Pack 301 LD and ID flow wrappers. Designed with long dwell sealing jaws, these machines ensure hermetically tight packaging to prevent gases from flowing in or out. In addition, the Pack 301 ID offers an inverted design which is particularly suitable for handling multipacks as well as hard-to-handle and fragile products. The MAP technology is also available for vertical form, fill and seal machinery from Bosch.

 

Improving on a trend

Modifying the packaging environment for food products has proven to be a popular approach that meets consumer demands and reduces logistical challenges for producers. Using MAP technologies, fresh food can be packaged with fewer or no preservatives while the product’s shelf life is extended, meeting the trend towards increasingly health-conscious consumers. Meanwhile, manufacturers profit from less product spoilage and waste as well as enhanced brand integrity.

 

The Pack 301 LD will be showcased at Emballage in Paris, France, from November 19 to 22, 2012, Hall 5a, Booth N° F064.
