Application 1,Banding tape should be stored in the condition of room temperature. If environment temperature is above 30degree, the products should be put in the freezer. 2,The testing of properties (for example: test volatile content) should be carried within one hour after the banding tape is taken from the plastic bag. 3,When apply the banding tape, keep it in the plastic bag at the room temperature for 24 hours after taking out from the freezer. 4,During the process of application, uneven tension and unsmooth banding would make the tape separation. You could continue to use after neatening the remaining pancake.
