U.S. launches frozen packaging bags

In order to overcome the shortcomings of improper freezing of refrigerators and damage to delicious foods, it was not long ago that a domestic vacuum packaging processing company in San Francisco designed and produced a kind of packaging fresh-keeping bag named “Friends of Food” that can better prevent food from being exposed to the refrigerator. Frozen deterioration. Foods that have been frozen in refrigerators can prevent them from deteriorating, but they also cause deterioration in the color, smell and taste of foods. Especially when the refrigerator stores pork, poultry, and other foods, deep freezing can destroy the structure of the meat and cause it to fade. Meat color, tasteless.
According to an independent microbiology research and research institution, experiments show that foods vacuum-packed with “Friends of Food” have much better antifreeze and deterioration capabilities than the reusable plastic food bags that are widely used today. The company's design and production of packaging bags, the advantage is to take full advantage of commercial-grade vacuum to preserve food, so as not to be directly exposed to oxidation in the air, it consists of three layers, one layer of nylon, used to increase strength. The wall of the bag is also equipped with a suction channel, which is the company's patented technology that makes vacuum packaging easier. This vacuum bag is resistant to freezing and can be heated by microwaves. It can also be boiled, washed or resealed. In order to test the performance of the fresh-keeping bags, researchers used chicken and beef as experimental subjects, and they were stored under the commonly used freezing temperature of home refrigerators after being packaged in vacuum packaging of new packaging bags and two kinds of refrigerators commonly used in the market. Comparing the experiments, the experimental results show that after four weeks of freezing, the chicken and beef preserved in the vacuum package of “Friends of Food” have no weight loss, the bag walls are free from ice chips, and there is no obvious deterioration such as fading, while the other two kinds of refrigerator storage bags are used for packaging. The weight of chicken and beef was significantly reduced, the wall of the bag was frozen, and freezing was observed with the naked eye two weeks after freezing. “Friends of Food” vacuum packaging bags and vacuum packaging machines can keep foods frozen for 3 to 5 times longer than normal storage bags.
