Food safety is a topic that the public is more concerned about now. Today, the editor will introduce to you some special food packaging paper.
solar thermal insulation paper
A paper developed in the United States that converts solar energy into heat. It’s like a solar collector. If you use it to wrap food and put it in a sunny location, it will raise the temperature of the food and keep it warm until the paper is opened and the heat will dissipate.
Far infrared packaging corrugated paper
The far-infrared packaging corrugated paper developed in Japan can be processed into cartons for packaging fruits, which can extend the shelf life to maintain the activation state of fruit water molecules, so that the freshness of fruits is more than double that of ordinary corrugated cartons. This paper is made of 100% natural pulp corrugated paper, coated with a ceramic layer that emits far infrared rays, and then a polyethylene film is coated on the ceramic to prevent the ceramic from falling off.
edible sterilization paper
Japan has developed a preservative paper that can be used for food packaging. The paper was dipped in an ethanol solution containing 20% succinic acid containing 33% sodium succinate and 0.07% sorbic acid, and then dried. Luwei food is packaged with this kind of wrapping paper, which can be kept at a high temperature of 38°C for 3 weeks, and the food will not deteriorate.
Dehydration functional paper
Japan has developed a paper that can be dehydrated without heat or additives. The surface material of this paper is a semi-permeable membrane (water permeable) with high osmotic pressure material and high polymer water absorption material inside. These water molecules are immobilized by polymeric water absorbents, as the water in the food can be transferred from the liquid to the highly permeable substance through the semi-permeable membrane. This kind of wrapping paper will not destroy the food tissue cells. It absorbs water along the cell gap, which can not only absorb the water on the surface of the food, but also absorb the deep water inside, absorb water at low temperature and other functions. This paper can inhibit enzyme activity, prevent protein decomposition, reduce microbial reproduction, maintain food freshness, enrich umami components, remove moisture, and improve toughness.
The above are the types and introductions of several special food packaging papers summarized by the editor. Did you understand!
