Oxygen Absorbers with Water Dust Oil Resistant Film
With the improvement of people's living standard, people pay more and more attention to food safety. However, food is a complex system, containing a large number of unsaturated fatty acids, proteins, flavor ingredients, metal catalysts, oxidase, pigments, vitamins and other easily oxidized ingredients. Food deterioration caused by oxygen will shorten the shelf life of food and even cause safety accidents, resulting in food safety problems. Studies have shown that most aerobic bacteria and facultative anaerobes can still grow, even if the oxygen volume fraction is as low as 2 to 3 percent in the packaging environment. It can be seen that it is of great significance to remove oxygen before food packaging.
Oxygen occupies 21% of the volume in the air, and it is the main cause of microbial reproduction, oil oxidation, and vigorous respiration of fruits, vegetables and grains, which leads to food corruption, discoloration, deterioration and decline in quality. Compared with other deoxygenation methods, deoxidizer preservation has the characteristics of low cost, simple operation, convenient use and high deoxygenation capacity. Vacuum packaging can only reduce the oxygen content to about 10%, and replacing it with inert gas can only reduce the oxygen content to about 2% .By chemical reaction with deoxidizer, the deoxidization rate can reach nearly 100%, and the oxygen concentration can be reduced to 1%, and the oxygen can be removed from the outside at any time for a long time. Unlike food additives, which are not ingested by the human body and have no toxicity problems, it also keeps the natural flavor of food well.
At present, the commonly used deoxidizer in food preservation is sealed into the packaging method, which is to seal the deoxidizer with oxygen absorption into the food packaging container, so as to remove oxygen from the inside of the container, thus preventing food oxidation and deterioration. The widely used deoxidizer packaging film on the market is composed of inner and outer membranes, which are divided into three layers :PET/ white paper /PE. The process adopts the method of puncture through three layers of compound paper with one needle. However, this kind of wrapping paper has the following problems: oil and water gas in food can easily enter into the packaging, making the content function weakened or invalid. The oxygen-removing material is easy to leak out along the hole, which pollutes the deoxygenated articles, such as grain, dried fruit, tobacco, fur and cotton silk textiles, and brings harm to people's health. At the same time, base paper and air permeable PE film are directly compounded, iron powder of packaging content can easily infiltrate into the paper layer to absorb moisture and oxidize and produce rust spots, thus affecting the appearance.
Therefore, a new high - tech production of three - proof film should be born. The paper film produced by using this technology does not need to be punched to avoid the possibility of water, oil and other infiltration into the deoxidizer. At the same time, it also avoids the possibility of the material inside the deoxidizer leaking and polluting the food. Oxygen molecules can still react with materials within the membrane through the tiny pores of the paper membrane material. As a result, the three - proof deoxidizer is widely used in oil, water and powdered food.

What does 30cc mean? 100cc? 200cc?
CC is a unit of measurement that is equivalent to milliliters. For example 1cc=1ml. and 1000cc or 1000ml=1 liter. So one 30cc oxygen absorber will absorb 90~240 cubic centimeters of oxygen. Remember that air is about 20% oxygen and 80% nitrogen. The oxygen absorbers remove the oxygen only. 100cc or 200cc are bigger and stronger oxygen packets. You would just use the suitable packets when packing your food.
