Correct use of 3M double-sided tape can improve Black Folding Magnetic Paper Boxes printing quality
1. The temperature has a great influence on the use of 3M tape on the board. All operations should be carried out at room temperature to avoid viscosity effects due to temperature.
2. Before the plate is pasted, the surface of the plate and the plate roller should be kept clean. Dirt, rust, ink and other dirt will destroy the adhesion of 3M tape, resulting in poor adhesion and warping. High-concentration alcohol should be used for cleaning the plate and plate roller, because other chemical solvents may damage the plate or sleeve.
3. When pasting the plate, the area of the 3M tape should be larger than the area of the plate, so the edge of the tape should be larger than the edge of the plate, which can greatly reduce the risk of warping the plate.
4. When pasting the plate, the interface of the plate and the interface of the tape should be avoided. If the interface of the plate is facing the interface of the tape, it will easily lead to the phenomenon that the plate at the interface is not sticky, warped and the plate falls off.
5. When sticking the tape, do not directly roll the tape with your hands. Take the double-sided tape and peel off part of the release paper on one side. Do not open the release paper immediately. After a part of the tape is fixed, peel off the release paper gradually.
6. After the printing plate is pasted, in order to prevent the ink and solvent from contacting the adhesive tape and the edge of the plate during printing and cleaning, a ring of edge banding tape can be attached around the plate to avoid the phenomenon of warping. The thickness of the edge banding tape should be thin.
7. When unloading the plate, it is recommended that the printing plate be removed slowly and smoothly at an angle of less than 90° (the angle between the removed printing plate and the surface of the cylinder), so as to avoid the wrinkle or breakage of the plate. The slower the unloading, the weaker the adhesive force to the tape plate, on the contrary, the faster the adhesive force is stronger. When removing the tape, the method is the same as that of removing the plate.
Flexo is a delicate printing process with many variables to control. As manufacturers have higher and higher requirements for label printing quality, the process control of each printing process becomes more and more important. I hope this simple discussion on plate-laying tape can help you.
