Bagged Salads are 100% fresh. Bagged or packaged salads are 100% natural and do not contain any preservatives or additives. The lettuces are kept fresh with modified atmosphere packaging and cold temperatures. Bagged salads must be kept refrigerated at all times. The modified atmosphere packaging system regulates and slows down the breathing rate of the lettuces extending the shelf life of the salad. Each salad blend breathes at a different rate and requires a customized bag or film to properly regulate the oxygen inside. Under refrigeration, the bag will naturally keep salads fresh and the bag also protects lettuces inside. The off odors or the weird smell that some have mentioned occurs when the salads warm-up and haven't been kept continuously cold. The warmer lettuces will produce a gas and then it builds up in the bag. Once the bag is opened it goes away but it is unappealing.
