A company in San Francisco, USA, designed and manufactured a vacuum packaged fresh-keeping bag that can better prevent food from freezing and deteriorating in the refrigerator. The bag is made up of three layers, one of which is nylon for increased strength. An air extraction channel is also implanted on the wall of the bag. This vacuum bag is resistant to freezing and can be heated by microwaves. It can also be boiled, washed or resealed. The experimental results show that there is no weight loss in the foods vacuum packed in this packaging bag, there is no ice flakes in the bag walls, there is no obvious deterioration phenomenon such as fading, the vacuum bag can make the frozen food preservation time longer than the ordinary storage bag 3 -5 times.
