How to paste and use the sheet protective film
The sheet protective film is generally applied to a flat surface. One method of application is to have two people apply the film. One person holds the film roll, while the other person pulls the loose end to the other end of the target material, fixes one end to the target surface, and then manually presses the sheet protective film into place and returns to the person holding the film roll This method is a test of labor intensity, but the effect is quite good.
Another method of manually applying a large sheet of sheet protective film to a large sheet of material is to apply the material to the film. The following procedure describes a relatively simple method:
1. Prepare a suitable large, flat work space-larger than the object to be protected-clean and free of dust, liquid or contaminants.
2. Stick a strip of double-sided tape near each end of the work space. These will be used to fix the sheet protective film, not the material to be protected.
3. With the adhesive side facing up, unfold a short section of the sheet protective film. Make sure it is smooth and wrinkle-free, and evenly attach the loose end to one of the double-sided tapes.
4. Continue to unfold the protective film and spread it over the entire length of the work surface until it is only a little shorter than the other double-sided tape. Now, lift the sheet protective film up and unfold it over the double-sided tape. Be careful not to pull the original connection end from the tape. Adjust the alignment of the film to ensure that it is straight, free of wrinkles and properly tightened, but not too tight to prevent the film from shrinking in the future. Place the film on the second double-sided tape.
5. Using a utility knife, cut the sheet protective film from the currently fixed film, which is waiting to receive the sheet to be protected.
6. Align and place one edge of the sheet on one end or one side of the sheet protective film. Place it on the inside of the double-sided tape fixing film.
7. Gradually place the parts on the adhesive film. Note: If the piece of material is flexible, when you place it on the film, bend it slightly to roll it down and allow air to escape between the material and the film.
8. To ensure that the material sheet is attached to the film, apply pressure to the material, especially along all edges, to ensure good adhesion. A clean paint roller can be used for this.
9. Use a utility knife to outline the outline of the part on the protective film, and cut off the excess film. Remove the excess and dispose of it. Carefully turn the part over, and if necessary, apply pressure directly to the film, working from the center to the outside to ensure that the entire area is well adhered.
10. Check whether the finished product is intact and wrinkle-free.
