Why Is A Packaged Food Grade Poly Bag Silver From Inside？
As you might have noticed, many packaged foods are often stored in silver-colored bags, and you might have wondered why the inside of the bag is silver in color. In this article, we will discuss the reasons behind this phenomenon and also introduce you to KXpack, a food grade poly bag packaging manufacturer that offers customized services and free samples.
The reason why the inside of the packaging bag is silver in color is that it is coated with a layer of aluminum. Aluminum is an excellent material for food packaging because it is lightweight, durable, and airtight. It is also resistant to moisture, light, and odor, making it an ideal choice for storing food products. The layer of aluminum on the inside of the bag acts as a barrier to oxygen, moisture, and other external factors that could damage the food.
The silver color of the food grade poly bag is due to the thin layer of aluminum coating that is applied to the inside of the bag. The aluminum layer is so thin that it is practically transparent, allowing the contents of the bag to be visible. However, it reflects light, giving the inside of the bag a shiny, silver appearance.
