The brightness of the film surface on both sides is inconsistent after calendering
in calendering, the pressure on both sides of the calendering belt is not equal, and the wear on both sides of the calendering belt is inconsistent. The pressure of the spring testing machine on both sides of the calendering Belt should be adjusted to make it equal during operation, and the parallelism of the hot pressing roller and the transmission roller should be adjusted to make the tension on both sides of the calendering belt consistent and wear evenly; It may also be that the thickness of both sides of the glazing oil is uneven, so it is necessary to adjust the use of glazing functional plastic film on vegetable and fruit packaging. Research the coating mechanism, check the parallelism and gap between the metering roller and the coating roller as a response to the "celebrity advertisement" effect of social concern, so as to make the coating thickness on both sides as consistent as possible
