Modified Atmosphere Packaging (MAP) will ensure that your produce is as fresh as possible for as long as possible.
When your business is supplying fresh-cut produce to major fast food chains and retail outlets, you have to ensure the produce is as fresh as possible for as long as possible.
Modified Atmosphere Packaging (MAP) contributes heavily to fulfilling this mandate, especially with a vegetable like lettuce, which browns easily.
At IEF, we engineer MAP films with controlled oxygen transmission rates (OTR) and moisture vapor transmission rates (MVTR) to help extend the shelf life of our customers’ produce.
By controlling OTR, we can regulate how much oxygen can permeate through film at specified conditions of temperature and relative humidity. Getting the right OTR is important because without the right oxygen barrier and seal integrity, the oxygen will cause ingress.
By controlling MVTR, we regulate the rate at which water vapor permeates through film—again, at specified conditions of temperature and relative humidity. For lettuce, this ensures that it is kept moist. Without the proper MVTR, lettuce would quickly gain moisture until it reaches equilibrium with the environmental relative humidity, making it soggy.
Depending on the food product or film specification, the OTR and MVTR can be engineered and controlled to improve product shelf life.
Looking for specialty film packaging for your food product? Lettuce know if we can help you with your packaging needs.
