What is the phenomenon of "permeating color"?
In the production of cooking resistant packaging bags, it may be difficult to prevent the phenomenon of "color penetration", resulting in large economic losses.
Color penetration often occurs in the packaging bag with nylon membrane as the outer layer material. When the outer membrane is replaced by polyester or BOPP film (other conditions remain unchanged), color penetration will not occur.
Red and purple are the most common colors. When there are defects in nylon membrane, the phenomenon of color penetration can not be completely eliminated, only the difference between the degree of penetration.
Temperature and water are the two basic factors of color penetration. Under the same temperature conditions, the same packaging bag in the oven will not appear penetration, when the temperature is lower than 70 ℃, the color penetration phenomenon will not appear in the sterilization of conventional time.
