PE protective film is as easy to use as a tape. However, as the width and length of the protective film strip increase, the difficulty factor will also increase a little bit. The difficulty of handling a tape that is 4 feet wide by 8 feet long is different from the difficulty of handling a tape that is 1 inch wide by 4 inches long.
A bigger challenge is to make a large piece of PE protective film perfectly aligned with the target surface, and then put it down without producing unsightly wrinkles or bubbles on the surface, especially on the surface of irregular products that are difficult to handle.
In order to better stick the protective film on the surface of the product and make it as perfect as possible, we need at least two people. One person is holding the protective film roll, while the other person pulls the torn end to the other end of the product to be protected, sticks the end to the target surface, and then manually presses the protective film in place, facing the person holding the roll people. This method is labor intensive and low in work efficiency, but the work effect is quite good.
Another way to manually apply large pieces of PE protective film to large pieces of material is to apply the material to the film. The following describes a relatively simple method of applying a large (4.5 x 8.5 ft) surface armor to a 4 x 8 ft material. You will need a roll of double-sided tape and a utility knife. (Note: The material in question should be able to tolerate a certain amount of processing for this method to run successfully.)
How to perfectly stick the protective film on the surface of the product:
1. Prepare a suitable large and flat work space-larger than the object to be protected-clean and free of dust, liquids or contaminants.
2. Place 4.5 feet of double-sided tape near each end of the workspace... about 8.5 feet apart. These will be used to hold the film, not the material to be protected.
3. With the adhesive side facing up, unfold a small section of the 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 place it along the length of the work surface not far from the other double-sided tape.
5. Now, roll up the film and place it on top of the double-sided tape. Be careful not to pull the original connection end out of the tape. Adjust the direction of the film to ensure that the film is straight and free of wrinkles. It is properly tightened, but not so tight that the film will shrink later. (When the film is stretched during use, when the film tries to return to its original shape, the edges tend to pull up.)
6. Lower the film onto the second strip of double-sided tape.
7. Using a utility knife, cut the roll from the film that is now waiting to receive the sheet to be protected.
8. Place one edge of a piece of material on one end or side of the protective film. Place it where the film is held by the double-sided tape.
9. Gradually place the parts on the adhesive film. Note: If the material is flexible, when you place it on the film, bend it slightly to roll it up and allow air to escape between the material and the film.
10. To ensure that the sheet is attached to the film, apply pressure to the material, especially along all edges, to ensure good adhesion. A clean paint roller may be used for this purpose.
11. Use a utility knife to trace part of the outline on the protective film and cut off the excess film. Delete the extra and deal with it.
12. Carefully turn the part, if necessary, apply pressure directly to the film, working from the middle to the outside to ensure good adhesion of the entire area.
13. Check that the finished piece is intact without wrinkle coverage.
For mass production, it is recommended to use a machine commonly called a laminator to coat the protective film. This is especially useful when both sides of the paper need to receive a protective film, because the machine can be applied to both sides at the same time.
